Abstract
OBJECTIVE The objective of this study was to report long-term results of an ongoing physician-sponsored, investigational device exemption (IDE) pivotal clinical trial using physician-modified endovascular grafts (PMEGs) for the treatment of patients with juxtarenal aortic aneurysms. METHODS Data from a nonrandomized, prospective, consecutively enrolling IDE clinical trial were used. Data collection began on April 1, 2011, and data lock occurred on January 2, 2024, with outcomes analysis through December 31, 2023. Primary safety and effectiveness end points were used to measure treatment success. The safety end point was defined as the proportion of subjects who experienced a major adverse event within 30 days of the procedure. The effectiveness end point was the proportion of subjects who achieved treatment success. Treatment success required the following at 12 months: technical success, defined as successful delivery and deployment of a PMEG with preservation of intended branch vessels; and freedom from: type I and III endoleak, stent graft migration >10 mm, aortic aneurysm sack enlargement >5 mm, and aortic aneurysm rupture or open conversion. RESULTS Over the 12-year study period, 228 patients were enrolled; 205 began the implant procedure, and 203 received PMEG. Thirteen patients withdrew prior to PMEG. Two withdrew (<1.0%) after failure to deploy due to tortuous iliac anatomy and are tracked as intent to treat, and a total of 24 withdrew after receiving the PMEG implant. Forty-four patients died during the study period. A total of 14 were deemed lost to follow-up. Fifty-nine completed the 5-year follow-up period, and 62 remain active in follow-up visits.Aneurysm anatomy, operative details, and lengths of stay were recorded and included: aneurysm diameter (mean, 67.5 mm; range, 49-124 mm), proximal seal zone length (mean, 41.6 mm; range, 18.9-92.9 mm), graft modification time (mean, 48.7 min), procedure time (mean, 137.7 min), fluoroscopy time (mean, 33.8 min), contrast material use (mean, 93.0 mL), estimated blood loss (mean, 118.8 mL), length of hospital stay (mean, 3.7 d), and intensive care unit length of stay (mean, 1.6 d).A total of 575 fenestrations were created for 387 renal arteries, 181 superior mesenteric arteries (SMAs), and 7 celiac arteries. Renal arteries were in 96% of patients and included 410 renal artery stents in 203 patients. The SMA was stented as needed and included one patient with an SMA stent placed before the procedure, 19 during the procedure, and 2 patients who underwent stent placement after the procedure. There were no open conversions or device migrations and 1 partial explant due to late distal graft occlusion. Three ruptures (1.4%) were recorded on days 830, 1346, and 1460. There was 1 presumed graft infection at 750 days (<0.5%) treated with? Thirty-day all-cause mortality was 2.9% (6/204). One type Ia, 1 type Ib, and 7 type III endoleaks were identified during follow-up and treated with successful reintervention at the 1-year period. The overall rate of major adverse events at 30 days was 15% (29/194). Technical success was 93.7%, and overall treatment success was 82.6%. CONCLUSIONS PMEG can be performed with low rates of long-term morbidity and mortality, confirming our early and midterm reports that endovascular repair with PMEG is safe, durable, and effective for managing patients with juxtarenal aortic aneurysms. While historically considered experimental, these results suggest that PMEG is a safe and durable option and should be considered for patients where off-the-shelf devices are not available.

J Vasc Surg 2024; 80:604-611. [PMID: 38904580 DOI: 10.1016/j.jvs.2024.04.054] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2024] [Revised: 04/23/2024] [Accepted: 04/24/2024] [Indexed: 06/22/2024]
Abstract
OBJECTIVE Despite regulatory challenges, device availability, and rapidly expanding techniques, off-label endovascular repair of complex aortic aneurysms (cAAs) has expanded in the past decade. Given the lack of United States Food and Drug Administration-approved endovascular technology to treat cAAs, we performed a national census to better understand volume and current practice patterns in the United States. METHODS Targeted sampling identified vascular surgeons with experience in off-label endovascular repair of cAAs. An electronic survey was distributed with institutional review board approval from the University of Rochester to 261 individuals with a response rate of 38% (n = 98). RESULTS A total of 93 respondents (95%) reported off-label endovascular repair of cAAs. Mean age was 45.7 ± 8.3 years, and 84% were male. Most respondents (59%) were within the first 10 years of practice, and 69% trained at institutions with a high-volume of off-label endovascular procedures for complex aortic aneurysms with or without a physician-sponsored investigational device exemption (PS-IDE). Twelve respondents from 11 institutions reported institutional PS-IDEs for physician-modified endografts (PMEGs), in-situ laser fenestration (ISLF), or parallel grafting technique (PGT), including sites with PS-IDEs for custom-manufactured devices. Eighty-nine unique institutions reported elective off-label endovascular repair with a mean of 20.2 ± 16.5 cases/year and ∼1757 total cases/year nationally. Eighty reported urgent/emergent off-label endovascular repair with a mean of 5.7 ± 5.4 cases/year and ∼499 total cases/year nationally. There was no correlation between high-volume endovascular institutions (>15 cases/year) and institutions with high volumes of open surgical repair for cAAs (>15 cases/year; odds ratio, 0.7; 95% confidence interval, 0.3-1.5; P = .34). Elective techniques included PMEG (70%), ISLF (30%), hybrid PMEG/ISLF (18%), and PGT (14%), with PMEG being the preferred technique for 63% of respondents. Techniques for emergent endovascular treatment of complex aortic disease included PMEG (52%), ISLF (40%), PGT (20%), and hybrid-PMEG/ISLF (14%), with PMEG being the preferred technique for 41% of respondents. Thirty-nine percent of respondents always or frequently offer referrals to institutions with PS-IDEs for custom-manufactured devices. The most common barrier for referral to PS-IDE centers included geographic distance (48%), longitudinal relationship with patient (45%), and costs associated with travel (33%). Only 61% of respondents participate in the Vascular Quality Initiative for complex endovascular aneurysm repair, and only 57% maintain a prospective institutional database. Eighty-six percent reported interest in a national collaborative database for off-label endovascular repair of cAA. CONCLUSIONS Estimates of off-label endovascular repair of cAAs are likely underrepresented in the literature based on this national census. PMEG was the most common technique for elective and emergent procedures. Under-reported off-label endovascular repair of cAA outcomes data appears to be limited by non-standardized PS-IDE reporting to the United States Food and Drug Administration, and the lack of Vascular Quality Initiative participation and prospective institutional data collection. Most participants are interested in a national collaborative database for endovascular repair of cAAs.

Abstract
OBJECTIVES Physician modified endografts (PMEGs) have expanded the scope of endovascular abdominal aortic repair beyond the infrarenal aorta. Patients with prohibitively high surgical risk and visceral segment disease are often candidates for this intervention, which mitigates much of the morbidity and mortality associated with conventional open repair. Here we present the institutional PMEG experience of a high-volume aortic center. METHODS We studied all PMEGs performed at our institution from 2012-2023. This includes cases that were submitted to the FDA in support of an IDE trial, as well as those in the subsequently approved IDE trial. Over this 11-year period we assessed the changes in operative characteristics and perioperative outcomes over time. Additionally, we compared the outcomes from PMEG cases to those of Zenith Fenestrated (ZFEN) grafts (done by the surgeon with the PMEG IDE), an alternative device used for aneurysms involving the lower visceral segment. Here we assessed operative characteristics, perioperative outcomes, and 5-year survival and reintervention rates. RESULTS When assessing the change over time for PMEG operative characteristics, we found a trend towards decreased fluoroscopy time and decreased proportions of completion type-I and type-III endoleaks (all p<.05). Perioperative outcomes have remained stable over this period with an overall perioperative mortality rate of 4.9% (noting that this registry also includes cases that were urgent and emergent). Despite the increased complexity of PMEGs relative to ZFENs we found comparable perioperative outcomes with regards to mortality (4.9% vs 4.3%, p=.86), permanent spinal cord ischemia (1.1% vs 0%, p=.38), postoperative MI (4.3% vs 2.9%, p=.60), postoperative respiratory failure (7.1% vs 4.3%, p=.43), and new dialysis usage (2.2% vs 4.3%, p=.35). Additionally, 5-year survival (PMEG 54% vs ZFEN 65%, p=.15) and freedom from reintervention (63% vs 74%, p=.07) were similar between these cohorts. CONCLUSIONS Throughout our greater than 10-year experience with PMEGs we have noted improvements in operative outcomes, which can likely be attributed to technological advances and increased physician experience. Additionally, we have found that PMEGs perform well when compared to ZFENs, despite being a more complicated repair that is able to treat a larger segment of the aorta. PMEGs are crucial for the comprehensive care of vascular patients with complex aortic disease. As further operative advancements are made, we only expect the usage of this intervention to increase.

Abstract
OBJECTIVE Prior studies suggest female sex is associated with worse outcomes after complex endovascular aneurysm repair (EVAR) due to anatomic differences. Therefore, we aimed to compare 30-day perioperative and long-term outcomes after complex EVAR by sex METHODS: A single-center retrospective review of consecutive elective and emergent complex EVAR with company-manufactured devices, laser fenestration, snorkel/periscope, or octopus technique was performed from 2012-2023. The primary outcome was a composite endpoint of any major adverse event (MAE), new-onset dialysis, or death within 30 days. Secondary 30-day technical and long-term outcomes were also assessed RESULTS: 293 patients (57 females, 19%), mean age 74 years, underwent complex EVAR with commercially available ZFEN (71%), p-Branch (2%), laser fenestration (8%), snorkel/periscope (16%), or octopus (2%) techniques. Females had significantly different aneurysm-related anatomic characteristics compared to males, including smaller aneurysm diameters (58 ± 7.2 vs 64 ± 13.2 mm, P<.001), more involved aneurysm extent (21.7% vs 9.8% thoracoabdominal, P=.04), increased renal artery calcification (43.9% vs 27.1%, P=.01), and smaller iliac (7.6 ± 1.3 vs 8.9 ± 1.8 mm, P<.01). Operative outcomes were similar; however, females had a greater need for adjunctive access conduits (21.1% vs 10.6%, P=.04), lower technical success (91.2% vs 98.3%, P=.02), and longer median [interquartile range] length of stay (3.0 [4.0] vs 2.0 [2.5] days, P<.001). The composite 30-day outcome of any MAE, new dialysis, or death was not significantly different (15.8% females vs 11.4% males, P=.37). Technical endpoints including 30-day rates of target artery occlusion and type 1 or 3 endoleak were also similar between groups. At mean follow-up of nearly 3 years, females had significantly lower rate of renal function decline (16.0% vs 41.9%, P<.001), but no differences were found in long-term all-cause mortality, aneurysm sac regression, reintervention, or total follow-up imaging studies between groups. CONCLUSIONS Females undergoing complex EVAR had challenging anatomy with higher intraoperative target artery occlusion, conduit use, and longer length of stay. However, 30-day and long-term outcomes were similar, suggesting females can undergo complex EVAR with high technical success and comparable perioperative outcomes to males. Females appeared to have protection from long-term renal function decline, which will be important for future study.

Abstract
Standard endovascular aortic repair (EVAR) has become the standard of care for treating infrarenal abdominal aortic aneurysms (AAAs) in patients with favorable anatomies, while patients with challenging AAA anatomies, and those with suprarenal or thoraco-abdominal aneurysms, still need alternative, more complex, solutions, including custom-made branched or fenestrated grafts, which are constrained by production delay and costs. To address urgent needs and complex cases, physicians have proposed modifying standard endografts by manually creating graft fenestrations. This allows for effective aneurysm exclusion and satisfactory patency of visceral vessels. Although physician-modified grafts (PMEGs) have demonstrated high technical success, standardized creation processes and long-term safety data are still lacking, necessitating further study to validate their clinical and legal standing. The aim of this article is to illustrate the state of the art with regard to this surgical technique, summarizing its origin, evolution, and the main clinical evidence supporting its effectiveness. The paper also aims to discuss the main medico-legal issues related to the use of PMEGs, with particular reference to the issue of safety related to the standardization of the surgical technique, medical liability profiles, and informed consent.

Abstract
Endovascular procedures are minimally invasive approaches to treat conditions affecting blood vessels without the need for large incisions. The benefits are less blood loss and faster recovery. One condition commonly treated endovascularly is aortic aneurysmal disease often secondary to atherosclerosis or chronic hypertension. As endovascular aneurysm repair becomes increasingly complex and sophisticated, the intraoperative organization and management of wires from multiple access sites becomes paramount. Often, the physician selects visceral or great vessels for delivery of stent grafts to maintain vessel patency. Loss of wire in critical target vessels and wire contamination pose significant patient risks. WireWatch (BioTex Inc. Houston, Texas, USA) is a novel device designed for intraoperative wire management to improve surgical field organization, provide wire stabilization, and prevent dropped wires. This case describes its use in a 73-year-old female undergoing a fenestrated endovascular aneurysm repair of 5.6 cm types IV thoracoabdominal aortic aneurysm.

Abstract
BACKGROUND Open surgery is still acknowledged as the gold standard for complex abdominal aortic aneurysm (c-AAA). Recently, advanced-endovascular aortic aneurysm repair (EVAR) for c-AAA has been developed, but its effectiveness compared to open surgery is still unclear. METHOD A systematic search was performed on the MEDLINE through PubMed and ScienceDirect databases. The search was aimed to investigate outcomes of both fenestrated- and chimney-EVAR (consider as advanced EVAR) compared to open surgery in c-AAA. Outcomes included postoperative complications, 30-day mortality, long-term mortality, and reintervention rate. Data were collected using the Mantel-Haenszel fixed effects model with relative risk (RR) as the effect size with 95% confidence interval (CI). RESULTS A total of 25 studies (n = 12,845 patients) were included in our study. The results demonstrated that advanced-EVAR correlated with diminished postoperative complications (RR 0.53; 95% CI 0.49-0.57; p < 0.001) compared to open surgery. Advanced-EVAR was associated with lower 30-day mortality compared to open surgery (RR 0.66; 95% CI 0.53-0.82; p < 0.001). Subgroup analysis revealed that fenestrated-EVAR resulted in superior outcomes (p < 0.001), whereas the chimney-EVAR subgroup did not show significant differences (p = 0.79), compared to open surgery in terms of 30-day mortality. Unfortunately, advanced-EVAR was associated with a higher long-term mortality rate (RR 1.46; 95% CI 1.20-1.78; p < 0.001) and a higher reintervention rate (RR 1.26; 95% CI 1.01-1.59; p = 0.04) compared to open surgery. CONCLUSION Advanced EVAR, especially fenestrated-EVAR, presented better short-term outcomes compared to open surgery; however, it failed to demonstrate superiority over open surgery in improving long-term outcomes.

J Vasc Surg 2024; 79:1360-1368.e3. [PMID: 38219966 PMCID: PMC11111352 DOI: 10.1016/j.jvs.2024.01.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2023] [Revised: 12/29/2023] [Accepted: 01/09/2024] [Indexed: 01/16/2024]
Abstract
OBJECTIVE Fenestrated endovascular aneurysm repair (FEVAR) has become a mainstay in treating complex aortic aneurysms, though baseline patient factors predicting long-term outcomes remain poorly understood. Proteinuria is an early marker for chronic kidney disease and associated with adverse cardiovascular outcomes, but its utility in patients with aortic aneurysms is unknown. We aimed to determine whether preoperative proteinuria impacts long-term survival after FEVAR. METHODS A single-institution, retrospective review of all elective FEVAR was performed. Preoperative proteinuria was assessed by urinalysis: negative (0-29 mg/dL), 1+ (30-100 mg/dL), 2+ (101-299 mg/dL), and 3+ (≥300 mg/dL). The cohort was stratified by patients with proteinuria (≥30 mg/dL) vs those without (<30 mg/dL). Baseline, perioperative, and long-term outcomes were compared. The primary outcome, all-cause mortality, was evaluated by Kaplan-Meier analysis and independent predictors with Cox proportional hazards modeling. RESULTS Among 181 patients who underwent standard FEVAR from 2012 to 2022 (mean follow-up 33 months), any proteinuria was noted in 30 patients (16.6%). Patients with proteinuria were more likely to be Black (10.0% vs 1.3%) with a lower estimated glomerular filtration rate (eGFR) (52.7 ± 24.7 vs 67.7 ± 20.5 mL/min/1.73 m2), higher Society for Vascular Surgery comorbidity score (10.9 ± 4.3 vs 8.2 ± 4.7) and calcium channel blocker therapy (50.0% vs 29.1%), and larger maximal aneurysm diameter (67.2 ± 16.9 vs 59.8 ± 9.8 mm) (all P < .05). Thirty-day mortality was higher in the proteinuria group (10.0% vs 1.3%; P = .03). Overall survival at 1 and 5 years was significantly lower for those with proteinuria (71.5% vs 92.3% and 29.5% vs 68.1%; log-rank P < .001). On multivariable analysis, preoperative proteinuria was independently associated with over threefold higher hazard of mortality (hazard ratio [HR]: 3.21, 95% confidence interval [CI]: 1.66-6.20; P < .001), whereas preoperative eGFR was not predictive (HR: 0.99, 95% CI: 0.98-1.01; P = .28). Additional significant predictors included chronic obstructive pulmonary disease (HR: 2.04), older age (HR: 1.05), and larger maximal aneurysm diameter (HR: 1.03; all P < .05). CONCLUSIONS In our 10-year experience with FEVAR, preoperative proteinuria was observed in 17% of patients and was significantly associated with worse survival. In this cohort, proteinuria was independently associated with all-cause mortality, whereas eGFR was not, suggesting that urinalysis may provide an additional simple metric for risk-stratifying patients before FEVAR.

National registry insights on genetic aortopathies and thoracic endovascular aortic interventions. J Vasc Surg 2024:S0741-5214(24)01101-7. [PMID: 38729586 DOI: 10.1016/j.jvs.2024.05.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2024] [Revised: 04/30/2024] [Accepted: 05/03/2024] [Indexed: 05/12/2024]
Abstract
OBJECTIVE Thoracic endovascular aortic repair (TEVAR) in patients with genetic aortopathies (GA) is controversial, given concerns of durability. We describe characteristics and outcomes after TEVAR in patients with GA. METHODS All patients undergoing TEVAR between 2010 and 2023 in the Vascular Quality Iniatitive were identified and categorized as having a GA or not. Demographics, baseline, and procedural characteristics were compared among groups. Multivariable logistic regression was used to evaluate the independent association of GA with postoperative outcomes. Kaplan-Meier methods and multivariable Cox regression analyses were used to evaluate 5-year survival and 2-year reinterventions. RESULTS Of 19,340 patients, 304 (1.6%) had GA (87% Marfan syndrome, 9% Loeys-Dietz syndrome, and 4% vascular Ehlers-Danlos syndrome). Compared with patients without GA, patients with GA were younger (50 years [interquartile range, 37-72 years] vs 70 years [interquartile range, 61-77 years]), more often presented with acute dissection (28% vs 18%), postdissection aneurysm (48% vs 17%), had a symptomatic presentation (50% vs 39%), and were less likely to have degenerative aneurysms (18% vs 47%) or penetrating aortic ulcer (and intramural hematoma) (3% vs 13%) (all P < .001). Patients with GA were more likely to have prior repair of the ascending aorta/arch (open, 56% vs 11% [P < .001]; endovascular, 5.6% vs 2.1% [P = .017]) or the descending thoracic aorta (open, 12% vs 2% [P = .007]; endovascular, 8.2% vs 3.6% [P = .011]). No significant differences were found in prior abdominal suprarenal repairs; however, patients with GA had more prior open infrarenal repairs (5.3% vs 3.2%), but fewer prior endovascular infrarenal repairs (3.3% vs 5.5%) (all P < .05). After adjusting for demographics, comorbidities, and disease characteristics, patients with GA had similar odds of perioperative mortality (4.6% vs 7.0%; adjusted odds ratio [aOR], 1.1; 95% confidence interval [CI], 0.57-1.9; P = .75), any in-hospital complication (26% vs 23%; aOR, 1.24; 95% CI, 0.92-1.6; P = .14), or in-hospital reintervention (13% vs 8.3%; aOR, 1.25; 95% CI, 0.84-1.80; P = .25) compared with patients without GA. However, patients with GA had a higher likelihood of postoperative vasopressors (33% vs 27%; aOR, 1.44; 95% CI, 1.1-1.9; P = .006) and transfusion (25% vs 23%; aOR, 1.39; 95% CI, 1.03-1.9; P = .006). The 2-year reintervention rates were higher in patients with GA (25% vs 13%; adjusted hazard ratio, 1.99; 95% CI, 1.4-2.9; P < .001), but 5-year survival was similar (81% vs 74%; adjusted hazard ratio, 1.02; 95% CI, 0.70-1.50; P = .1). CONCLUSIONS TEVAR for patients with GA seemed to be safe initially, with similar odds for in-hospital complications, in-hospital reinterventions, and perioperative mortality, as well as similar hazards for 5-year mortality compared with patients without GA. However, patients with GA had higher 2-year reintervention rates. Future studies should assess long-term durability after TEVAR compared with the recommended open repair to appropriately weigh the risks and benefits of endovascular treatment in patients with GA.

[PMID: 37931886 PMCID: PMC10960673 DOI: 10.1016/j.jvs.2023.11.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2023] [Revised: 10/28/2023] [Accepted: 11/01/2023] [Indexed: 11/08/2023]
Abstract
OBJECTIVE Despite the advantages that fenestrated endovascular aortic repair has over open repair, it is accompanied by the consequence of radiation exposure, which can result in long-term complications for both the patient and surgical staff. Fiber Optic RealShape (FORS) technology is a novel advancement that uses emitted light from a fiber optic wire and enables the surgeon to cannulate vessels in real time without live fluoroscopy. This technology has been implemented at select centers to study its effectiveness for cannulation of target vessels and its impact on procedural radiation. METHODS We collected prospective data on physician-modified endograft (PMEG) cases before and after the introduction of FORS technology. FORS PMEGs were matched with up to three conventional fluoroscopy cases by number of target vessels, inclusion of a bifurcated device below, aneurysm extent, and patient body mass index. The procedural radiation parameters were compared between these cohorts. Within the FORS cohort, we analyzed the rate of successful target vessel cannulation for all cases done with this technology (including cases other than PMEGs), and we compared the radiation between the cannulations using only FORS with those that abandoned FORS for conventional fluoroscopy. RESULTS Nineteen FORS PMEGs were able to be matched to 45 conventional fluoroscopy cases. Procedures that used FORS technology had significantly reduced total air kerma (527 mGy vs 964 mGy), dose area product (121 Gy∗cm2 vs 186 Gy∗cm2), fluoroscopy dose (72.1 Gy∗cm2 vs 132.5 Gy∗cm2), and fluoroscopy time (45 minutes vs 72 minutes). There was no difference in procedure length, total contrast, or digital subtraction angiography. Within FORS cases, 66% of cannulations were completed using only FORS. Cannulations using only FORS had significant reduction of navigation air kerma (5.0 mGy vs 26.5 mGy), dose area product (1.2 Gy∗cm2 vs 5.1 Gy∗cm2), and fluoroscopy time (0.6 minutes vs 2.3 minutes) compared with cannulations abandoning FORS for conventional fluoroscopy. CONCLUSIONS This study demonstrates the advantages of FORS for total procedural radiation as well as during individual cannulation tasks. The implementation of FORS for target vessel catheterization has the potential to decrease the total degree of radiation exposure for the patient and surgical staff during complex endovascular aortic surgeries.

[PMID: 37963191 PMCID: PMC10776526 DOI: 10.1093/bjs/znad376] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2023] [Revised: 08/17/2023] [Accepted: 10/22/2023] [Indexed: 11/16/2023]
Abstract
BACKGROUND It is unclear whether women derive mortality benefit from early repair of abdominal aortic aneurysms (AAA). The aim of this study was to compare short- and mid-term mortality for women treated at small versus large diameters. METHOD Women receiving elective repair of AAA at small (49-54 mm) and large (≥55 mm) diameters from 2008 to 2022 were extracted from the Swedish National Registry for Vascular Surgery (n = 1642 women). The effect of diameter on 90-day, 1- and 3-year mortality was studied in logistic regression and propensity score models. Age, co-morbidities, smoking and repair modality were considered as confounders. Men (n = 9047) were analysed in parallel. RESULTS Some 1642 women were analysed, of whom 34% underwent repair at small diameters (versus 52% of men). Women with small (versus large) AAAs were younger (73 versus 75 years, P < 0.001), and 63% of women in both size groups had endovascular repairs (P = 0.120). Mortality was 3.5% (90 days), 7.1% (1 year) and 15.8% (3 years), with no differences between the size strata. There was no consistent association between AAA size and mortality in multivariable models. Sex differences in mortality were almost entirely due to mortality in younger-than-average women versus men (3-year mortality: small AAAs 11.1% versus 7.3%, P < 0.030, or large 14.4% versus 10.7%, P < 0.038). CONCLUSION Mortality in women is high and unaffected by AAA size at repair. The optimal threshold for women remains undefined. The higher rupture risk in women should not automatically translate into a lower, women-specific threshold.

Eur J Vasc Endovasc Surg 2024; 67:119-129. [PMID: 37572869 DOI: 10.1016/j.ejvs.2023.08.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Revised: 07/13/2023] [Accepted: 08/07/2023] [Indexed: 08/14/2023]
Abstract
OBJECTIVE Despite widespread use, long term outcomes for fenestrated endovascular aneurysm repair (FEVAR) are uncertain. This meta-analysis reports long term survival, freedom from re-intervention, target vessel patency, and one year sac regression after FEVAR. DATA SOURCES Systematic review and meta-analysis to pool time to event data according to PRISMA guidelines. The study was registered with the international prospective register of systematic reviews (PROSPERO) (ID: CRD42023401468). REVIEW METHODS Medline, Embase, and Cochrane databases were searched from 1992 - 2023; articles were independently screened by two authors. Publication of complete time to event data for any outcome of interest was an inclusion criterion. Raw Kaplan-Meier probabilities were directly extracted from published curves and pooled by random effects. Risk of bias was assessed using ROBINS I and certainty with GRADE. RESULTS A total of 3 569 records were retrieved, 2 869 screened after duplicate removal, yielding 37 included studies (n = 4 371). The pooled mean age was 73.2 years (interquartile range [IQR] 72.2, 73.7) and 87.4% were male (95% confidence interval [CI] 85.8 - 88.9). Pooled Kaplan-Meier estimated probabilities of survival (n = 34 studies, n = 4 192 patients) at one, three, and five years were 91.6% (95% CI 90.2 - 92.9), 80.8% (95% CI 78.0 - 83.2), and 65.1% (95% CI 60.9 - 69.1). For freedom from re-intervention (n = 24, n = 3 211 patients) at one, three, and five years these were 90.2% (95% CI 87.3 - 92.7), 80.9% (95% CI 76.5 - 84.9), and 73.8% (95% CI 67.1 - 79.6). For target vessel patency (n = 13, n = 5805 target vessels) at one, three, and five years, these were 96.6% (95% CI 94.9 - 98.0), 94.5% (95% CI 91.7 - 96.7), and 93.1% (95% CI 89.3 - 96.0). Pooled estimate of sac regression (n = 8, n = 560) at one year was 40.2% (95% CI 28.9 - 52.7). Risk of bias was judged as moderate in 11 studies and low for the remaining 26. CONCLUSION There are moderate to low certainty data supporting reasonable long term outcome estimates following fenestrated endovascular aneurysm repair. Beyond five years there is a lack of data in the literature.

Greater Patient Travel Distance is Associated with Perioperative and One-Year Cost Increases After Complex Aortic Surgery. Ann Vasc Surg 2023; 97:289-301. [PMID: 37355014 PMCID: PMC10739569 DOI: 10.1016/j.avsg.2023.05.040] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2023] [Revised: 05/23/2023] [Accepted: 05/25/2023] [Indexed: 06/26/2023]
Abstract
BACKGROUND With increasing regionalization of complex aortic surgery within fewer US centers, patients may face increased travel burden when accessing aortic surgery. Longer travel distances have been associated with inferior outcomes after major surgery; however, the impacts of distance on reinterventions and costs have not been described. This study aims to assess the association between patient travel distance and longer-term outcomes including costs and reinterventions after complex aortic surgery. METHODS A retrospective review was conducted of all patients in the Vascular Implant Surveillance and Interventional Outcomes Network database undergoing complex endovascular aortic repair including internal iliac or visceral vessel involvement, complex thoracic endovascular aortic repair including Zone 0-2 proximal extent or branched devices, and complex open abdominal aortic aneurysm repair including suprarenal or higher clamp sites. Travel distance was stratified by Rural-Urban Commuting Area population-density category. Multinomial logistic regression models, negative-binomial models, and zero-inflated Poisson models were used to assess the association between travel distance and index procedural and comprehensive first-year costs, long-term imaging, and long-term reinterventions, respectively. RESULTS Between 2011 and 2018, 8,782 patients underwent complex aortic surgery in the Vascular Implant Surveillance and Interventional Outcomes Network database, including 4,822 complex endovascular aortic repairs, 2,672 complex thoracic endovascular aortic repairs, and 1,288 complex open abdominal aortic aneurysm repairs. Median travel distance was 22.8 miles (interquartile range 8.6-54.8 miles, range 0-2,688.9 miles). Median age was 75 years for all distance quintiles. Patients traveling farther were more likely to be female (26.8% in quintile 5 [Q5] vs. 19.9% in Q1, P < 0.001) and to have had a prior aortic surgery (20.8% for Q5 vs. 5.9% for Q1, P < 0.001). Patients traveling farther had higher index procedural costs, with adjusted odds ratio (OR) 2.34 (95% confidence interval [CI] 1.86-2.94, P < 0.0001) of being in the highest cost tertile versus lowest for patients in Q5 vs. Q1. For patients with ≥ 1-year follow-up, those traveling farther had higher imaging costs, with adjusted Q5 OR 1.55 (95% CI 1.22-1.95, P = 0.0002), and comprehensive first-year costs, with adjusted Q5 OR 2.06 (95% CI 1.57-2.70, P < 0.0001). In contrast, patients traveling farther had similar numbers of reinterventions and imaging studies postoperatively. CONCLUSIONS Patients traveling farther for complex aortic surgery have higher procedural costs, postoperative imaging costs, and comprehensive first-year costs. These patients should be targeted for increased care coordination for improved outcomes and healthcare system burden.

Ann Vasc Surg 2023; 97:163-173. [PMID: 37586562 PMCID: PMC10956480 DOI: 10.1016/j.avsg.2023.07.102] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2023] [Revised: 07/19/2023] [Accepted: 07/31/2023] [Indexed: 08/18/2023]
Abstract
BACKGROUND Fenestrated endovascular aneurysm repair (FEVAR) is a well-established treatment approach for juxtarenal and short-neck infrarenal aortic aneurysms. Recommendations and clinical outcomes are lacking for offering FEVAR in patients with chronic kidney disease (CKD). We aimed to compare short- and long-term outcomes for patients with none-to-mild versus moderate-to-severe CKD undergoing FEVAR. METHODS We retrospectively reviewed consecutive patients undergoing standard FEVAR with Cook devices at a single institution. The cohort was stratified by preoperative CKD stage none-to-mild or moderate-to-severe (CKD 1-2 and CKD 3-5, respectively). The primary outcome was postoperative acute kidney injury (AKI). Secondary outcomes included 30-day perioperative complications, 1- and 5-year rates of overall survival, dialysis, renal target artery patency, endoleak, and reintervention assessed by the Kaplan-Meier method. Aneurysm sac regression, number of surveillance computed tomography (CT) scans, and CKD stage progression were assessed at latest follow-up. Multivariate Cox proportional hazards modeling was used to evaluate the association of CKD stage 3 and stage 4-5 with all-cause mortality, controlling for differences in baseline characteristics. RESULTS From 2012- to 2022, 184 patients (of which 82% were male) underwent FEVAR with the Cook ZFEN device (mean follow-up 34.3 months). Group CKD 3-5 comprised 77 patients (42%), was older (75.2 vs. 73.0 years, P = 0.04), had increased preoperative creatinine (1.6 vs. 0.9 mg/dL, P < 0.01), and demonstrated increased renal artery ostial calcification (37.7% vs. 21.5%, P = 0.02) compared with Group CKD 1-2. Perioperatively, CKD 3-5 sustained higher estimated blood loss (342 vs. 228 ml, P = 0.01), longer operative times (186 vs. 162 min, P = 0.04), and longer length of stay (3 vs. 2 days, P < 0.01). Kaplan-Meier 1- and 5-year survival estimates were lower for CKD 3-5 (82.3% vs. 95.1%, P < 0.01 and 55.4% vs. 70.8%, P = 0.02). Fewer CKD 3-5 patients remained free from chronic dialysis at 1 year (94.4% vs. 100%, P = 0.015) and 5 years (84.7% vs. 100%, P < 0.01). There were no significant differences in postoperative AKI rate (CKD 1-2 6.5% vs. CKD 3-5 14.3%, P = 0.13), long-term renal artery patency, reinterventions, type I or III endoleak, mean sac regression, or total follow-up CT scans between groups. CKD stage progression occurred in 47 patients (31%) at latest follow-up but did not differ between stratified groups (P = 0.17). On multivariable modeling, age (hazard ratio 1.05, 95% confidence interval 1.01-1.09, P = 0.02) and CKD stage 4-5 (hazard ratio 6.39, 95% confidence interval 2.26-18.05, P < 0.01) were independently associated with mortality. CONCLUSIONS Preoperative CKD status did not negatively impact the durability or technical success related to aneurysm outcomes after FEVAR. Worsening CKD stage was associated with lower 1- and 5-year overall survival and freedom from dialysis after FEVAR with no statistically significant differences in 30-day or long-term technical aneurysm outcomes.

Abstract
PURPOSE To describe and compare mid-term outcomes from 2 real-world data collection efforts on fenestrated and branched endovascular aortic repair (fbEVAR) for complex abdominal aortic aneurysms (AAAs) in France and to evaluate the potential of health care databases for long-term post-market surveillance (PMS) and continued reimbursement approval. METHODS Two real-world studies were conducted in France: a retrospective health care database study (SNDS) and a prospective clinical study. In the SNDS study, data from implantation and/or hospital stays occurring during follow-up were extracted for all patients treated with the study devices from April 2012 to December 2018. In the clinical study, high-risk patients undergoing fbEVAR with the study devices were enrolled consecutively at 15 sites in France from December 2016 to November 2018. RESULTS Data from 1073 patients were extracted from SNDS and compared with analogous variables from 186 patients in the clinical study. Most demographic details were similar between studies (SNDS vs clinical: mean age, 71.9 vs 71.8 years; men, 91.0% vs 89.8%), as was 30-day mortality (SNDS: 5.5%, clinical: 4.3%). Patients received custom-made fenestrated or branched devices (SNDS: 80.7%, clinical: 96.2%) or CE-marked Zenith Fenestrated devices (SNDS: 19.3%, clinical: 3.8%). Initial or technical success was above 94% for both studies. Two-year freedom from all-cause mortality was 80.0% (SNDS) and 85.1% (clinical study). Two-year freedom from aneurysm-related mortality was 93.8% (SNDS) and 94.6% (clinical study). Detailed imaging outcomes were not captured within SNDS; however, information on secondary procedures to restore patency was available and used as a surrogate measure for secondary interventions. Two-year freedom from secondary interventions was 73% for the SNDS study. In the clinical study, at 2 years, aneurysm stability or shrinkage was observed in 92.3% of patients, freedom from target vessel primary patency loss was above 95% for all visceral target vessels, and freedom from secondary interventions was 79.1%. CONCLUSION Real-world outcomes from the SNDS and clinical study suggest positive mid-term outcomes in high-risk populations following fbEVAR for complex AAAs. The similarities between these studies suggest that the use of health care databases may be an alternative to prospective clinical studies for long-term follow-up and PMS. CLINICAL IMPACT Positive results following endovascular repair of complex abdominal aortic aneurysms are observed from data extracted from both the French health care database and a post-market clinical study despite initial high-risk patient status and diverse center experience. These outcomes parallel more rigorously designed studies and suggest that with careful study design, real-world data collections have high translatable value to add to the clinical understanding of fenestrated and branched endovascular aortic repair (fbEVAR).

Severity of acute kidney injury is associated with decreased survival after fenestrated and branched endovascular aortic aneurysm repair. J Vasc Surg 2023; 78:892-901. [PMID: 37330702 DOI: 10.1016/j.jvs.2023.05.034] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2023] [Revised: 05/19/2023] [Accepted: 05/22/2023] [Indexed: 06/19/2023]
Abstract
OBJECTIVE Acute kidney injury (AKI) occurs frequently in complex aortic surgery and has been implicated in perioperative and long-term survival. This study sought to characterize the relationship between AKI severity and mortality after fenestrated and branched endovascular aortic aneurysm repair (F/B-EVAR). METHODS Consecutive patients enrolled by the US Aortic Research Consortium in 10, prospective, nonrandomized, physician-sponsored investigational device exemption studies evaluating F/B-EVAR, between 2005 and 2023, were included in this study. Perioperative AKI during hospitalization was defined by and staged using the 2012 Kidney Disease Improving Global Outcomes criteria. Determinants of AKI were evaluated with backward stepwise mixed effects multivariable ordinal logistic regression. Survival was analyzed with conditionally adjusted survival curves and backward stepwise mixed effects Cox proportional hazards modelling. RESULTS In the study period, 2413 patients with a median (interquartile range [IQR]) age of 74 years (IQR, 69-79 years) underwent F/B-EVAR. The median follow-up duration was 2.2 years (IQR, 0.7-3.7 years). The median baseline estimated glomerular filtration rate (eGFR) and creatinine were 68 mL/min/1.73 m2 (IQR, 53-84 mL/min/1.73 m2) and 1.1 mg/dL (IQR, 0.9-1.3 mg/dL), respectively. Stratification of AKI identified 316 patients (13%) with stage 1 injury, 42 (2%) with stage 2 injury, and 74 (3%) with stage 3 injury. Renal replacement therapy was initiated during the index hospitalization in 36 patients (1.5% of cohort, 49% of stage 3 injuries). Thirty-day major adverse events were associated with AKI severity (all P ≤ .0001). Multivariable predictors of AKI severity included baseline eGFR (proportional odds ratio, 0.9 per 10 mL/min/1.73 m2 [95% confidence interval (CI), 0.85-0.95 per 10 mL/min/1.73 m2]; P < .0001), baseline serum hematocrit (0.58 per 10% [95% CI, 0.48-0.71 per 10%]; P < .0001), renal artery technical failure during aneurysm repair (3 [95% CI,1.61-5.72]; P = .0006), and total operating time (1.05 per 10 minutes [95% CI, 1.04-1.07 per 10 minutes]; P < .0001). One-year unadjusted survivals for AKI severity strata were 91% (95% CI, 90%-92%) for no injury, 80% (95% CI, 76%-85%) for stage 1 injury, 72% (95% CI, 59-87%) for stage 2 injury, and 46% (95% CI, 35-59%) for stage 3 injury (P<.0001). Multivariable determinants of survival included AKI severity (stage 1, hazard ratio [HR], 1.6 [95% CI, 1.3-2]); stage 2, HR, 2.2 [95% CI, 1.4-3.4]); stage 3 HR, 4 [95% CI, 2.9-5.5]; P < .0001), decreased eGFR (HR, 1.1 [95% CI, 0.9-1.3]; P = .4), patient age (HR, 1.6 per 10 years [95% CI, 1.4-1.8 per 10 years]; P < .0001), baseline chronic obstructive pulmonary disease (HR, 1.5 [95% CI, 1.3-1.8]; P < .0001), baseline congestive heart failure (HR, 1.7 [95% CI, 1.6-2.1]; P < .0001), postoperative paraplegia (HR, 2.1 [95% CI, 1.1-4]; P = .02), and procedural technical success (HR, 0.6 [95% CI, 0.4-0.8]; P = .003). CONCLUSIONS AKI, as defined by the 2012 Kidney Disease Improving Global Outcomes criteria, occurred in 18% of patients after F/B-EVAR. Greater severity of AKI after F/B-EVAR was associated with decreased postoperative survival. The predictors of AKI severity identified in these analyses suggest a role for improved preoperative risk mitigation and staging of interventions in complex aortic repair.

Ann Vasc Surg 2023; 96:195-206. [PMID: 37075835 DOI: 10.1016/j.avsg.2023.03.037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2022] [Revised: 01/31/2023] [Accepted: 03/31/2023] [Indexed: 04/21/2023]
Abstract
BACKGROUND To evaluate longer-term results of a cohort treated with primary chimney endovascular aneurysm sealing (ChEVAS) for complex abdominal aortic aneurysms or secondary ChEVAS after failed endovascular aneurysm repair/endovascular aneurysm sealing. METHODS A single-center study was conducted of 47 consecutive patients (mean age 72 ± 8 years, range 50-91; 38 men) treated with ChEVAS from February 2014 to November 2016 and followed through December 2021. The main outcome measures were all-cause mortality (ACM), aneurysm-related mortality, occurrence of secondary complications and conversion to open surgery. Data are presented as the median (interquartile range [IQR]) and absolute range. RESULTS 35 patients received a primary ChEVAS (=group I) and 12 patients a secondary ChEVAS (=group II). Technical success was 97% (group I) and 92% (group II); 30-day mortality was 3% and 8%, respectively. The median proximal sealing zone length was 20.5 mm (IQR 16, 24; range 10-48) in group I and 26 mm (IQR 17.5, 30; range 8-45) in group II, respectively. During a median time of follow-up of 62 months (range 0-88), ACM amounted to 60% (group I) and 58% (group II); aneurysm mortality was 29% and 8%, respectively. An endoleak was seen in 57% (group I: 15 type Ia endoleaks, four isolated type Ib, and 1 endoleak type V) and 25% (group II: 1 endoleak type Ia, one type II, and 2 type V), aneurysm growth in 40% and 17%, migration in 40% and 17%, resulting in 20% and 25% conversions in group I and II, respectively. Overall a secondary intervention was performed in 51% (group I) and 25% (group II), respectively. The occurrence of complications did not significantly differ between the 2 groups. Neither the number of chimney grafts, nor the thrombus ratio significantly affected the occurrence of abovementioned complications. CONCLUSIONS While initially delivering a high technical success rate, ChEVAS fails to provide acceptable longer-term results both in primary and secondary ChEVAS, resulting in high rates of complications, secondary interventions and open conversions.

Abstract
BACKGROUND Endovascular aneurysm repair (EVAR) is often attempted in patients with marginal anatomy. These patients' midterm outcomes are available in the Vascular Quality Initiative for analysis. STUDY DESIGN Retrospective analysis of prospectively collected data in the Vascular Quality Initiative from patients who underwent elective infrarenal EVAR between 2011 and 2018. Each EVAR was identified as either on- or off-instructions for use (IFU) based on aortic neck criteria. Multivariable logistic regression models were used to assess associations between aneurysm sac enlargement, reintervention, and type Ia endoleak with IFU status. Kaplan-Meier time-to-event models estimated reintervention, aneurysm sac enlargement, and overall survival. RESULTS We identified 5,488 patients with at least 1 follow-up recorded. Those treated off-IFU included 1,236 patients ([23%] mean follow-up 401 days) compared with 4,252 (77%) treated on-IFU (mean follow-up 406 days). There was no evidence of significant differences in crude 30-day survival (96% vs 97%; p = 0.28) or estimated 2-year survival (97% vs 97%; log-rank p = 0.28). Crude type Ia endoleak frequency was greater in patients treated off IFU (2% vs 1%; p = 0.03). Off-IFU EVAR was associated with type Ia endoleak on multivariable regression model (odds ratio 1.84 [95% CI 1.23 to 2.76]; p = 0.003). Patients treated off IFU vs on IFU experienced had increased risk of reintervention within 2 years (7% vs 5%; log-rank p = 0.02), a finding consistent with results from the Cox modeling (hazard ratio 1.38 [95% CI 1.06 to 1.81]; p = 0.02). CONCLUSIONS Patients treated off IFU were at greater risk for type Ia endoleak and reintervention, although they had similar 2-year survival compared with those treated on IFU. Patients with anatomy outside IFU should be considered for open surgery or complex endovascular repair to reduce the probability for revision.

Abstract
OBJECTIVE Abdominal aortic graft and endograft infections (AGIs) are rare complications following aortic surgery. Radical surgery (RS) with resection of the infected graft and reconstruction with extra-anatomical bypass or in situ reconstruction is the preferred therapy. For patients unfit for RS, a semi-conservative (SC), graft preserving strategy is possible. This paper aimed to compare survival and infection outcomes between RS and SC treatment for AGI in a nationwide cohort. METHODS Patients with abdominal AGI related surgery in Sweden between January 1995 and May 2017 were identified. The Management of Aortic Graft Infection Collaboration (MAGIC) criteria were used for the definition of AGI. Multivariable regression was performed to identify factors associated with mortality. RESULTS One hundred and sixty-nine patients with surgically treated abdominal AGI were identified, comprising 43 SC (14 endografts; 53% with a graft enteric fistula [GEF] in total) and 126 RS (26 endografts; 50% with a GEF in total). The SC cohort was older and had a higher frequency of cardiac comorbidities. There was a non-significant trend towards lower Kaplan-Meier estimated five year survival for SC vs. RS (30.2% vs. 48.4%; p = .066). A non-significant trend was identified towards worse Kaplan-Meier estimated five year survival for SC patients with a GEF vs. without a GEF (21.7% vs. 40.1%; p = .097). There were significantly more recurrent graft infections comparing SC with RS (45.4% vs. 19.3%; p < .001). In a Cox regression model adjusting for confounders, there was no difference in five year survival comparing SC vs. RS (HR 1.0, 95% CI 0.6 - 1.5). CONCLUSION In this national AGI cohort, there was no mortality difference comparing SC and RS for AGI when adjusting for comorbidities. Presence of GEF probably negatively impacts survival outcomes of SC patients. Rates of recurrent infection remain high for SC treated patients.

Low-volume surgeons can have better outcomes at certain hospital settings for open abdominal aortic repairs. J Vasc Surg 2023; 78:638-646. [PMID: 37172621 DOI: 10.1016/j.jvs.2023.04.041] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2022] [Revised: 03/28/2023] [Accepted: 04/09/2023] [Indexed: 05/15/2023]
Abstract
OBJECTIVE The volume-outcomes relationship is cross-cutting among open abdominal aortic operations, where higher-volume surgeons have better perioperative outcomes. However, there has been minimal focus on low-volume surgeons and how to improve their outcomes. This study sought to identify if there are any differences in outcomes among low-volume surgeons for open abdominal aortic surgeries by different hospital settings. METHODS We used the 2012-2019 Vascular Quality Initiative registry to identify all patients who underwent open abdominal aortic surgery for aneurysmal or aorto-iliac occlusive disease by a low-volume surgeon (<7 operations annually). We categorized high-volume hospitals using three distinct definitions: those that performed ≥10 operations annually, those with at least one high-volume surgeon, and by the number of surgeons (1-2 surgeons, 3-4 surgeons, 5-7 surgeons, and 8+ surgeons). Outcomes included 30-day perioperative mortality, overall complications, and failure-to-rescue. We compared outcomes among low-volume surgeons using univariable and multivariable logistic regressions across each of these three hospital categorizations. RESULTS Among 14,110 patients who underwent open abdominal aortic surgery, 10,252 (7 3%) were performed by 1155 low-volume surgeons. Two-thirds of these patients (66%) underwent their surgery at a high-volume hospital, fewer than one-third (30%) at a hospital that had at least one high-volume surgeon, and one-half (49%) at hospitals with at least five surgeons. Among all patients operated on by low-volume surgeons, rates of 30-day mortality were 3.8%, perioperative complications were 35.3%, and failure-to-rescue were 9.9%. Low-volume surgeons operating at high-volume hospitals for aneurysmal disease had lower rates of perioperative death (adjusted odds ratio [aOR], 0.66; 95% confidence interval [CI], 0.48-0.90) and failure-to-rescue (aOR, 0.70; 95% CI, 0.50-0.98), but similar rates of complications (aOR, 1.06; 95% CI, 0.89-1.27). Similarly, patients undergoing their operation at hospitals that had at least one high-volume surgeon had lower rates of death (aOR, 0.71; 95% CI, 0.50-0.99) for aneurysmal disease. Patient outcomes among low-volume surgeons for aorto-iliac occlusive disease did not vary by hospital setting. CONCLUSIONS The majority of patients undergoing open abdominal aortic surgery have a low-volume surgeon, where outcomes are slightly better for those taking place at a high-volume hospital. Focused and incentivized interventions may be needed to improve outcomes among low-volume surgeons across all practice settings.

Abstract
PURPOSE Ruptured mycotic pararenal aortic aneurysms are rare and serious condition that requires prompt treatment. Open surgery with aortic resection and in-situ or extra-anatomic reconstruction is the standard treatment. The aim of this technical note is to report urgent endovascular treatment using a readily available custom-made device (created for another patient), with a back-table modification using pericardium patch and a new fenestration. TECHNIQUE In preoperative measurements on centerline-based workstation, aortic diameter in proximal and distal landing zone and target vessel position matched the measurements of graft plan of custom-made device (CMD) besides left renal artery. To address current patient`s anatomy, closure of the nonsuitable fenestration with pericardial patch and creation of new fenestration (1 cm above and 1:15 hours posterior to original fenestration) for the respective target vessel have been performed. Postoperative computed tomography angiography (CTA) scan showed complete exclusion of aneurysm, perfused target vessels, and no endoleak. Under resistance-based antibiotic therapy, the patient was asymptomatic and showed normal infection parameters in blood samples postoperatively. CONCLUSION In the hands of an experienced endovascular aortic surgeon modification of a custom-made device is a quick and feasible technique in this emergency situation. Long-term follow-up must confirm the durability and reliability of this new technique. CLINICAL IMPACT The described technique of modification of a custom-made endograft can provide an alternative endovascular treatment option for urgent complex abdominal aortic pathologies. Compared to the current available treatment modalities, like physician modified endografts, off-the-shelf branched devices, parallel grafts and in-situ fenestration, it can save considerable time and provides reasonable sealing in ruptured cases. The technique offers a valuable add-on to the armamentarium of experienced endovascular physicians.

Abstract
BACKGROUND Endovascular management of thoracoabdominal aneurysms (TAAA) is becoming more common. Technological advances including custom devices under the Physician-Sponsored Investigational Device Exemption (PS-IDE), physician-modified endografts (PMEG), and parallel stenting techniques have expanded the extent of disease that is amenable to endovascular treatment. Patients within the PS-IDE studies are a highly selected group of patients, whereas patients treated with PMEG as captured within the Society for Vascular Surgery Vascular Quality Initiative (SVS VQI) represent a real-world experience. Research within both the SVS VQI on PMEG and the US Aortic Research Consortium (US-ARC) has demonstrated a relationship between extent of aneurysmal disease and mortality after complex endovascular TAAA repair, but no direct comparison of these cohorts has been conducted. In this study, we sought to compare outcomes of custom PS-IDE devices with off-label uses of commercially available devices for the endovascular management of TAAAs. METHODS A retrospective review of patients presenting for elective endovascular TAAA repair for asymptomatic disease between 2011 and 2019 was conducted within both the SVS VQI registry and the US-ARC. Patients within the SVS VQI registry were treated with either PMEG or with parallel stenting techniques. Patients within the US-ARC were treated with PS-IDE custom devices. The extent of aneurysm disease was defined by the deployment zones documented for the devices entered in the registry using Crawford extents I to V. Primary outcomes were 30-day and 1-year mortality rates. RESULTS A total of 3212 patients were included in the study: 1571 PMEG/parallel stenting within the VQI registry and 1641 with PS-IDE within the US-ARC database. The majority of patients presented with extent IV aneurysms (n = 1827 [57%]), with extent IV aneurysms being slightly more prevalent within the US-ARC cohort. Maximal aneurysm diameter within each extent did not vary between the US-ARC and VQI cohorts. Across all patients, the 30-day mortality was 4.4% and the 1-year mortality was 12.2%. Unadjusted mortality at 30-days was 6.7% within the VQI, and 2.2% in the US-ARC (P < .001). The unadjusted 1-year mortality was 14.3% within the VQI and 10.2% within the US-ARC (P < .001). When adjusted for aneurysm extent, similar differences in 30-day and 1-year survivals were identified. CONCLUSIONS Patients treated in PS-IDE studies had better 30-day and 1-year survival rates compared with those treated with a similar extent of disease using off-label approaches in a real-world registry. These differences are complex and likely associated with a number of factors, including arterial anatomy, patient comorbidities, device construct, and volume outcomes, as well as complex and unmeasurable surgeon- and patient-specific factors.

Longer patient travel distance is associated with increased non-index readmission after complex aortic surgery. J Vasc Surg 2023; 77:1607-1617.e7. [PMID: 36804783 PMCID: PMC10213129 DOI: 10.1016/j.jvs.2023.02.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2022] [Revised: 02/07/2023] [Accepted: 02/09/2023] [Indexed: 02/17/2023]
Abstract
OBJECTIVE Recently evolving practice patterns in complex aortic surgery have led to regionalization of care within fewer centers in the United States, and thus patients may have to travel farther for complex aortic care. Travel distance has been associated with inferior outcomes after non-vascular surgery, particularly non-index readmission. This study aims to assess the impact of patient travel distance on perioperative outcomes and readmissions after complex aortic surgery. METHODS A retrospective review was conducted of all patients in the Vascular Quality Initiative and Vascular Implant Surveillance and Interventional Outcomes Network databases undergoing complex endovascular aortic repair (EVAR) including internal iliac or visceral vessel involvement, complex thoracic endovascular aortic repair (TEVAR) including zone 0 to 2 proximal extent or branched devices, and complex open abdominal aortic aneurysm (AAA) repair including suprarenal or higher clamp sites. Travel distance was stratified by rural/urban commuting area (RUCA) population-density category. Wilcoxon and χ2 tests were used to assess relationships between travel distance quintiles and baseline characteristics, mortality, and readmission. Travel distance and other factors were included in multivariable Cox models for survival and Fine-Gray competing risk models for freedom from readmission. RESULTS Between 2011 and 2018, 8782 patients underwent complex aortic surgery in the Vascular Quality Initiative and Vascular Implant Surveillance and Interventional Outcomes Network databases, including 4822 complex EVARs, 2672 complex TEVARs, and 1288 complex open AAA repairs. Median travel distance was 22.8 miles (interquartile range [IQR], 8.6-54.8 miles). Median age was 75 years for all distance quintiles, but patients traveling longer distances were more likely female (26.8% in quintile 5 [Q5] vs 19.9% in Q1; P < .001), white (93.8% of Q5 vs 83.8% of Q1; P < .001), to have larger-diameter AAAs (median 59 mm for Q5 vs 55 mm for Q1; P < .001), and to have had prior aortic surgery (20.8% for Q5 vs 5.9% for Q1; P < .001). Overall 30-day readmission was more common at farther distances (18.1% for Q5 vs 14.8% for Q1; P = .003), with higher non-index readmission (11.2% for Q5 vs 2.7% for Q1; P < .001) and conversely lower index readmission (6.9% for Q5 vs 12.0% for Q1; P < .001). Multivariable-adjusted Fine-Gray models confirmed greater hazard of non-index readmission with farther distance, with a Q5 hazard ratio of 3.02 (95% confidence interval, 2.12-4.30; P < .001). Multivariable-adjusted Cox models demonstrated no association between travel distance and long-term survival but found that non-index readmission was associated with increased long-term mortality (hazard ratio, 1.46; 95% confidence interval, 1.20-1.78; P = .0001). CONCLUSIONS Patients traveling farther for complex aortic surgery demonstrate higher non-index readmission, which, in turn, is associated with increased long-term mortality risk. Aortic centers of excellence should consider targeting these patients for more comprehensive follow-up and care coordination to improve outcomes.

Abstract
Background: To investigate the usability of Mixed-Reality (MR) during patient education in patients scheduled for abdominal aortic aneurysm (AAA) repair. Patients and methods: Consecutive patients scheduled for elective AAA repair were block-randomized in either the Mixed-Reality group (MR group) or the conventional group (control group). Patients of both groups were educated about open and endovascular repair of their respective AAA. The MR group was educated using a head-mounted display (HMD) demonstrating a three-dimensional virtual reconstruction of the respective patient's vascular anatomy. The control group was educated using a conventional two-dimensional monitor to display the patient's vasculature. Outcomes were informational gain as well as patient satisfaction with the educational process. (DRKS-ID: DRKS00025174). Results: 50 patients were included with 25 patients in either group. Both groups demonstrated improvements in scores in the Informational Gain Questionnaire (IGQ) when comparing pre- and post-education scores. (MR group: 6.5 points (±1.8) versus 7.9 points (±1.5); Control group: 6.2 points (±1.8) versus 7.6 points (±1.6); p<0.01) There was no significant difference between the MR group and the control group either in informational gain (MR group: 1.4±1.8; Control group: 1.4±1.8; p=0.5) nor in patient satisfaction scores (MR group: mean 18.3 of maximum 21 points (±3.7); Control group: mean 17 of 21 points (±3.6); p=0.1) Multiple regression revealed no correlation between the use of MR and informational gain or patient satisfaction. Usability of the system was rated high, and patients' subjective assessment of MR was positive. Conclusions: The use of MR in patient education of AAA patients scheduled for elective repair is feasible. While patients reported positively on the use of MR in education, similar levels of informational gain and patient satisfaction can be achieved with MR and conventional methods.

Abstract
Gender Medicine is rapidly emerging as a branch of medicine that studies how many diseases common to men and women differ in terms of prevention, clinical manifestations, diagnostic-therapeutic approach, prognosis, and psychological and social impact. Nowadays, the presentation and identification of many pathological conditions pose unique diagnostic challenges. However, women have always been paradoxically underestimated in epidemiological studies, drug trials, as well as clinical trials, so many clinical conditions affecting the female population are often underestimated and/or delayed and may result in inadequate clinical management. Knowing and valuing these differences in healthcare, thus taking into account individual variability, will make it possible to ensure that each individual receives the best care through the personalization of therapies, the guarantee of diagnostic-therapeutic pathways declined according to gender, as well as through the promotion of gender-specific prevention initiatives. This article aims to assess potential gender differences in clinical-radiological practice extracted from the literature and their impact on health and healthcare. Indeed, in this context, radiomics and radiogenomics are rapidly emerging as new frontiers of imaging in precision medicine. The development of clinical practice support tools supported by artificial intelligence allows through quantitative analysis to characterize tissues noninvasively with the ultimate goal of extracting directly from images indications of disease aggressiveness, prognosis, and therapeutic response. The integration of quantitative data with gene expression and patient clinical data, with the help of structured reporting as well, will in the near future give rise to decision support models for clinical practice that will hopefully improve diagnostic accuracy and prognostic power as well as ensure a more advanced level of precision medicine.

Abstract
PURPOSE This study aimed to investigate the demographic and anatomic characteristics, as well as perioperative and follow-up results of fenestration and parallel techniques for the endovascular repair of complex aortic diseases. MATERIALS AND METHODS A retrospective study was conducted on 67 consecutive patients underwent endovascular treatment for complex aortic diseases including abdominal aortic aneurysm (AAA), thoracoabdominal aneurysm (TAAA), aortic dissection, or prior endovascular repair with either fenestrated and parallel endovascular aortic repair (f-EVAR or ch-EVAR) at a single institute from 2013 to 2021. Choices of intervention were made by the disease' emergency, patients' general condition, the anatomic characteristics, as well as following the recommendation from the devices' guidelines. Patients' clinical demographics, aortic disease characteristics, perioperative details, and disease courses were discussed. Short- and mid-term follow-up results were obtained and analyzed. Endpoints were aneurysm-related and unrelated mortality, branch instability, and renal function deterioration. RESULTS Totally, 34 and 27 patients received f-EVAR and ch-EVAR, while 6 patients received a combination of both. Fenestrated endovascular aortic repair was conducted mainly in AAA affecting visceral branches and TAAA, whereas ch-EVAR was normally utilized for infrarenal AAA. Regarding the average number of reconstructed arteries per patient, there was a significant difference among f-EVAR, ch-EVAR, and the combination group (mean = 2.3 ± 0.9, 1.4 ± 0.6, 3.5 ± 0.5, p<0.001). Primary technical success was achieved in 28 (82.4%), 22 (81.5%), and 3 (50.0%) patients for each group. Besides operational time (5.77 ± 2.58, 4.47 ± 1.44, p=0.033), no significant difference was observed for blood transfusion, intensive care unit (ICU) or hospital stay, blood creatinine level, 30-day complications, or follow-up complications between patients undergoing f-EVAR or ch-EVAR. Patients receiving combination of both techniques had a higher rate of blood transfusion (p=0.044), longer operational time (p=0.008) or hospital stay (p=0.017), as well as more stent occlusion (p=0.001), endoleak (p=0.004) at short-term and a higher rate of endoleak (p=0.023) at mid-term follow-up. CONCLUSION In conclusion, this study demonstrated that f-EVAR and ch-EVAR techniques had acceptable perioperative and follow-up results and should be considered viable alternatives when encountering complex aortic diseases. CLINICAL IMPACT This study sought to investigate the baseline and pathological characteristics, as well as perioperative and follow-up results of f-EVAR and ch-EVAR at a single Chinese institution. F-EVAR (mostly physician-modified f-EVAR) was applied in patients with a wide range of etiologies and disease types, while ch-EVAR was preferred for AAA in older patients with an average higher ASA grade. Our experience suggested acceptable safety and efficacy both for techniques, and no significant difference was observed between the two groups regarding any short or mid-term adverse events.

The effect of supraceliac versus infraceliac landing zone on outcomes following fenestrated endovascular repair of juxta-/pararenal aortic aneurysms. J Vasc Surg 2023; 77:9-19.e2. [PMID: 35981657 PMCID: PMC9789162 DOI: 10.1016/j.jvs.2022.08.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Revised: 07/29/2022] [Accepted: 08/05/2022] [Indexed: 02/03/2023]
Abstract
OBJECTIVE With increasing experience in fenestrated endovascular aneurysm repair (FEVAR) over time, devices designed to treat juxta-/pararenal aortic aneurysms have evolved in complexity to extend to more proximal landing zones and incorporate more target vessels. We assessed perioperative outcomes in patients who underwent juxta-/pararenal FEVAR with supraceliac vs infraceliac sealing in the Vascular Quality Initiative. METHODS We identified all patients who underwent elective FEVAR (commercially available FEVAR and physician-modified endografts) for juxta-/pararenal aortic aneurysms in the Vascular Quality Initiative between 2014 and 2021. Supraceliac sealing was defined as proximal sealing in aortic zone 5, or zone 6 with a celiac scallop/fenestration/branch or celiac occlusion. Primary outcomes were perioperative and 3-year mortality. Secondary outcomes included completion endoleaks, in-hospital complications, and factors associated with 3-year mortality. We calculated propensity scores and used inverse probability-weighted Cox regression and logistic regression modeling to assess outcomes. RESULTS Among 1486 patients identified, 1246 patients (84%) underwent infraceliac sealing, and 240 patients (16%) underwent supraceliac sealing. Of the supraceliac patients, 74 (31%) had a celiac scallop, 144 (60%) had a celiac fenestration/branch, and 22 (9.2%) had a celiac occlusion (intentional or unintentional). After risk-adjusted analyses, there were no differences in perioperative mortality following supraceliac sealing compared with infraceliac sealing (2.3% vs 2.5%; hazard ratio [HR], 0.67; 95% confidence interval [CI], 0.26-1.8; P = .42), or 3-year mortality (12% vs 15%; HR, 0.89; 95% CI, 0.53-1.5; P = .67). Compared with infraceliac sealing, supraceliac sealing was associated with lower odds of type-IA completion endoleaks (odds ratio [OR], 0.24; 95% CI, 0.05-0.67), but higher odds of any complication (12% vs 6.9%; OR, 1.6; 95% CI, 1.01-2.5) including cardiac complications (5.5% vs 1.9%; OR, 2.6; 95% CI, 1.3-5.1), lower extremity ischemia (3.0% vs 0.9%; OR, 3.2; 95% CI, 1.02-9.5), and acute kidney injury (16% vs 11%; OR, 1.6; 95% CI, 1.05-2.3). Though non-significant, there was a trend towards higher risk of spinal cord ischemia following supraceliac sealing compared with infraceliac sealing (1.7% vs 0.8%; OR, 2.2; 95% CI, 0.70-6.4). There were no differences in bowel ischemia between groups (1.7% vs 1.5%; OR, 0.83; 95% CI, 0.24-1.23). A more proximal aneurysm disease extent was associated with higher 3-year mortality (HR zone 8 vs 9, 1.7; 95% CI, 1.1-2.5), whereas procedural characteristics had no influence. CONCLUSIONS Compared with sealing at an infraceliac level, supraceliac sealing was associated with lower risk of type IA endoleaks and similar mortality. However, clinicians should be aware that supraceliac sealing was associated with higher perioperative morbidity. Future studies with longer follow-up are needed to adequately assess durability differences to comprehensively weigh the risks and benefits of utilizing a higher sealing zone within the visceral aorta for juxta-/pararenal FEVAR.

Introduction: This systematic review with network meta-analysis aimed at comparing the medium-term results of open surgery (OS), fenestrated endovascular repair (FEVAR), and chimney endovascular repair (ChEVAR) in patients with juxta/pararenal abdominal aortic aneurysms (JAAAs/PAAAs). Materials and methods: MEDLINE, SCOPUS, and Web of Science were searched from inception date to 1st July 2022. Any studies comparing the results of two or three treatment strategies (ChEVAR, FEVAR, or OS) on medium-term outcomes in patients with JAAAs/PAAAs were included. Primary outcomes were all-cause mortality, aortic-related reintervention, and aortic-related mortality, while secondary outcomes were visceral stent/bypass occlusion/occlusion, major adverse cardiovascular events (MACEs), new onset renal replacement therapy (RRT), total endoleaks, and type I/III endoleak. Results: FEVAR (OR = 1.53, 95%CrI 1.03-2.11) was associated with higher medium-term all-cause mortality than OS. Sensitivity analysis including only studies that analysed JAAA showed that FEVAR (OR = 1.65, 95%CrI 1.08-2.33) persisted to be associated with higher medium-term mortality than OS. Both FEVAR (OR = 8.32, 95%CrI 3.80-27.16) and ChEVAR (OR = 5.95, 95%CrI 2.23-20.18) were associated with a higher aortic-related reintervention rate than OS. No difference between different treatment options was found in terms of aortic-related mortality. FEVAR (OR = 13.13, 95%CrI 2.70-105.2) and ChEVAR (OR = 16.82, 95%CrI 2.79-176.7) were associated with a higher rate of medium-term visceral branch occlusion/stenosis compared to OS; however, there was no difference found between FEVAR and ChEVAR. Conclusions: An advantage of OS compared to FEVAR and ChEVAR after mid-term follow-up aortic-related intervention and vessel branch/bypass stenosis/occlusion was found. This suggests that younger, low-surgical-risk patients might benefit from open surgery of JAAA/PAAA as a first approach.

Disparities in reporting and representation by sex, race, and ethnicity in endovascular aortic device trials. J Vasc Surg 2022; 76:1244-1252.e2. [PMID: 35623599 PMCID: PMC9613501 DOI: 10.1016/j.jvs.2022.05.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2022] [Accepted: 05/15/2022] [Indexed: 11/21/2022]
Abstract
OBJECTIVE Vulnerable populations, including women and racial and ethnic minorities, have been historically underrepresented in clinical trials. We, therefore, studied the demographics of patients enrolled in pivotal endovascular aortic device trials in the United States. METHODS We queried the Food and Drug Administration (FDA) medical devices database for all FDA-approved endografts for the treatment of aortic aneurysms, transections, and dissections from September 1999 to November 2021. These included abdominal endovascular aortic repair (EVAR), thoracic EVAR (TEVAR), fenestrated EVAR (FEVAR) devices, and dissection stents. Multiple cases of approval for expanded indications were included separately. The primary outcomes included the proportion of trials reporting participant sex, race, and ethnicity and the proportion of enrolled participants across sex, racial, and ethnic groups. RESULTS The FDA provided 29 approvals from 29 trials of 24 devices: 15 EVAR devices (52%), 12 TEVAR devices (41%), 1 FEVAR device (3.4%), and 1 dissection stent (3.4%). These trials had included 4046 patients. Of the 29 trials, all had reported on the sex of the participants, and the median female enrollment was 21% (interquartile range [IQR], 11%-34%). The EVAR trials had the lowest female enrollment (11%; IQR, 8.7%-13%) compared with 41% (IQR, 27%-45%) in the TEVAR trials, 21% in the FEVAR trial, and 34% in the dissection stent trial (P < .01 for the difference). Only 52% of the trials had reported the three most common racial groups (White, Black, Asian), and only 48% had reported Hispanic ethnicity. The TEVAR trials were the most likely to report all three racial groups and Hispanic ethnicity (92% and 75%, respectively), while the EVAR trials had the lowest reporting rates (13% and 20%, respectively). Where reported, the median enrollment of racial and ethnic groups across the trials was as follows: Black patients, 9.8% (FEVAR, 0%; EVAR, 1.9%; TEVAR, 12%; dissection stent, 25%; P = .01); Asian patients, 2.4% (EVAR, 0.6%; FEVAR, 2.4%; TEVAR, 2.5%; dissection stent, 11%; P = .24); and Hispanic patients, 3.8% (EVAR, 1.3%; FEVAR, 2.4%; TEVAR, 3.9%; dissection stent, 4.1%; P = .75). CONCLUSIONS Racial and ethnic minority groups were underrepresented and underreported in pivotal aortic device trials that led to FDA approval. Female patients were also underrepresented in these aortic trials, especially for EVAR. These data suggest the need for standardization of reporting practices and minimum thresholds for minority and female participation in pivotal trials to promote equitable representation.

Abstract
BACKGROUND Aortic aneurysms are normally treated by an endovascular approach. Due to the lack of devices and increasing experience, there is a growing number of complex aneurysms undergoing repair by physician modified endografts (PMEGs). Previously, our practice was to target visceral vessels exclusively through upper extremity access. We have since then shifted to an all transfemoral approach when possible. This study aims to show the operative benefits of transfemoral only approaches. METHODS Patients who underwent a PMEG at a tertiary center between 2015 and 2020 were included. Patients were stratified into 2 groups based on branched vessel approach-transfemoral only versus axillary or composite (axillary and femoral). Forty-one patients had a pararenal or type IV thoracoabdominal aortic aneurysm (TAAA) and 15 patients had more complex TAAA. Primary outcomes were operative time, radiation exposure, fluoroscopy time, contrast, and blood loss. Secondary outcomes were 30-day mortality and major adverse events. Linear regression models were used to evaluate the association between approach type and the main outcomes. RESULTS Fifty-six patients were included with 48% (n = 27) in the transfemoral group and 52% (n = 29) in the axillary/composite group. Baseline characteristics were similar between the groups. Intraoperative outcomes revealed significant increase in the average operative time (418 vs. 246 min, P < 0.001), in radiation exposure (2,755 vs. 1,740 mGy, P = 0.03), in fluoroscopy time (108 vs. 74 min, P = 0.01) and in blood loss (579 vs. 202 cc, P = 0.002) in the axillary/composite group compared to the transfemoral group. There was no significant difference in 30-day mortality or major adverse events including stroke. CONCLUSIONS This study shows a transfemoral approach to complex endovascular aortic aneurysm repair as opposed to axillary/composite approach has decreased operative time, radiation exposure, and fluoroscopy time and no significant differences in 30-day mortality or major adverse events. When treating complex aneurysms, improving efficiency is important to minimize morbidity to patients and operators.

Abstract
Renal arteries are involved in a wide spectrum of pathologies including atherosclerosis, fibromuscular dysplasia, Takayasu arteritis, aneurysms, and aortic type B dissections extending into main renal arteries. They manifest as renovascular hypertension, renal ischemia, and cardiovascular dysfunction. The location of the renal arteries in relation to the abdominal aortic aneurysm is a critical determinant of interventional options and long-term prognosis. This article provides a comprehensive review of the role of interventional radiologists in transcatheter interventions in various pathologies involving the main renal arteries with analysis of epidemiology, pathophysiology, newer interventional techniques, and management options.

Capturing the Complexity of Open Abdominal Aortic Surgery in the Endovascular Era. J Vasc Surg 2022; 76:1520-1526.

Abstract
OBJECTIVE Volume and quality benchmarks for open abdominal aortic surgery and particularly open aortic aneurysm repair (OAR) in the endovascular era are guided by the Society for Vascular Surgery (SVS) guidelines, but the Vascular Quality Initiative (VQI) OAR module fails to capture the full spectrum of complex OAR. We hypothesized that VQI-ineligible complex OAR is the dominant form of open repairs performed at a VQI-participating tertiary center. METHODS All OAR cases performed at a single tertiary care center from 2007 to 2020 were reviewed. The VQI OAR criteria were applied with exclusions (non-VQI) defined as concomitant renal bypass, clamping above the superior mesenteric artery (SMA) or celiac artery, repairs performed for trauma, anastomotic aneurysm, isolated iliac aneurysm, or infected aneurysms. Linear regression was used to assess temporal trends. RESULTS Among a total of 481 open abdominal aortic operations, 355 (74%) were OAR. The average annual OAR volume remained stable over 14 years (25 ± 6; P = .46). Non-VQI OAR comprised 54% of all cases and persisted over time (R2 = .047, P = .46). Supra-celiac clamping (35%) was often necessary. The proportion of endograft explantation cases significantly increased over time from 4% in 2007 to 20% in 2019 (P = .01). Infectious indications represented 20% (n = 70) of cases. Visceral branch grafts were performed in 16% of all cases. OAR for ruptured aneurysm constituted 10% of cases. Thirty-day mortality was significantly higher in non-VQI vs. VQI-eligible OAR cases (10% vs. 4%; P = .04). CONCLUSIONS Complex OAR comprises a majority of OAR cases in a contemporary tertiary referral hospital, yet these cases are not accounted for in the VQI. Creation of a "complex OAR" VQI module would capture these cases in a quality-driven national registry and help to better inform benchmarks for volume and outcomes in aortic surgery.

Abstract
OBJECTIVES Fenestrated endovascular aneurysm repair (FEVAR) is increasingly used in the treatment of juxtarenal aortic aneurysms and short-neck infrarenal aneurysms. Reinterventions (REIs) occur frequently, contributing to patient morbidity and resource utilization. We sought to determine if REIs impact long-term survival after FEVAR. METHODS A single-institution retrospective review of all Cook ZFEN repairs was performed. Patients with ≥6 months follow-up and without adjunctive branch modifications were included. REI was defined as any aneurysm, device, target branch, or access-related intervention after the index procedure. REIs were categorized by early (<30 days) or late (≥30 days), indication (branch, endoleak, limb, access-related, or other), and target branch/device component. Patients were stratified into REI vs No REI and Branch REI vs Non-Branch REI. RESULTS Of 219 consecutive ZFEN from 2012-2021, 158 patients met inclusion criteria. Forty-one (26%) patients underwent a total of 51 REIs (10 early, 41 late) over a mean follow-up of 33.9 months. The most common indication for REI was branch-related 61% (31/51), with the renal arteries most frequently affected 51% (26/51). The only differences found in baseline, aneurysm, or device characteristics were a higher mean SVS comorbidity score (9.6 vs 7.9, P=.04) and larger suprarenal neck angle (23.3 vs 17.1 degrees, P=.04) in No REI, while REI had larger mean proximal seal zone diameter (26.3 vs 25.1 mm, P=.03) and device diameter (31.9 vs 30.0 mm, P=.002) than No REI. Technical success and operative characteristics were similar between groups, except for longer mean fluoroscopy time (74.9 vs 60.8 min, P=.01) and longer median length of stay (2 vs 2 days, P=.006) in REI. While the rate of early major adverse events (<30 days) was higher in REI (24.4% vs 6.0%, P=.001), 30-day mortality was not statistically different (4.9% vs 0.9%, P=.10). On Kaplan-Meier analysis, freedom from REI at 1- and 5-years was 85.7% and 62.6%, respectively, in the overall cohort. There was no difference in estimated 5-year survival between REI and No REI (62.8% vs 63.5%, log-rank P=.87) and Branch REI and Non-Branch REI (71.8% vs 49.9%, log-rank P=.16). In multivariate analysis, REI did not predict mortality; age, the SVS comorbidity score, and preoperative maximum aneurysm diameter each increased the hazard of death (HR 1.07 95% CI 1.02-1.12, P=.007; HR 1.10, 95% CI 1.01-1.18, P=.02; HR 1.05, 95% CI 1.02-1.08, P=.003 respectively). CONCLUSIONS Following ZFEN, 26% of patients required a total of 51 REIs with most occurring ≥30 days and 61% being branch-related, with no influence on 5-year survival. Age, comorbidity, and baseline aneurysm diameter independently predicted mortality. FEVAR mandates lifelong surveillance and protocols to maintain branch patency. Despite their relative frequency, REIs do not influence 5-year post-procedural survival.

Cadaver Simulation is Associated with Increased Comfort in Performing Open Vascular Surgery Among Integrated Vascular Surgery (0+5) Residents and Recent Graduates. Ann Vasc Surg 2022; 86:68-76. [PMID: 35697278 DOI: 10.1016/j.avsg.2022.05.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2022] [Revised: 05/10/2022] [Accepted: 05/13/2022] [Indexed: 11/24/2022]
Abstract
BACKGROUND With the evolution in vascular surgery toward increased endovascular therapy and decreased open surgical training, comfort with open procedures by current trainees is declining. A proposed method to improve this discomfort is simulator training. We hypothesized that open, cadaver, and endovascular surgery simulation would be associated with increased self-perceived comfort in performing corresponding procedures. METHODS Integrated (0 + 5) vascular surgery residents and recent graduates in the United States were asked to complete a survey quantifying comfort via a Likert scale with procedures and experience with simulation training. Simulation groups were then matched using coarsened exact matching. Ordinal logistic regression assessed the association between simulation experience and comfort in performing procedures. RESULTS Surveys were completed by 68 trainees and 20 attending surgeons in their first 5 years of practice. On unmatched analyses, there were no significant differences in comfort in performing any open or endovascular aorto-mesenteric or peripheral vascular procedures between respondents who reported experience with open or endovascular simulation, respectively. However, respondents who reported cadaver simulation experience (58%, 51/88) had a significantly higher reported comfort score performing open juxtarenal aortic repair (2.4 vs. 1.7), superior mesenteric artery thrombectomy or bypass (2.5 vs. 1.9), inferior vena cava or iliac vein repair (2.2 vs. 1.7), axillary-femoral artery bypass (3.4 vs. 2.5), femoral-popliteal artery bypass (3.7 vs. 2.8), and inframalleolar artery bypass (2.8 vs. 2.1; all P < 0.05). After matching on training level, number of abdominal cases completed, and number of open vascular cases completed, ordinal logistic regression demonstrated that previous cadaver simulation was significantly associated with increased comfort in performing open aortic repairs, venous repair, visceral revascularization, and peripheral bypasses. CONCLUSIONS In this nationally representative sample, cadaver, but not open or endovascular, simulation was associated with increased comfort in performing open vascular surgery. Providing cadaver simulation to trainees may help to improve comfort levels in performing open surgery. Integrated vascular surgery training programs should consider implementing these experiences into their curriculum.

Abstract
OBJECTIVE Abdominal aortic aneurysms (AAAs) with adverse morphology of the aneurysm neck are "complex". Techniques employed to repair complex aneurysms include open surgical repair (OSR) and a number of on label endovascular techniques such as fenestrated endovascular aneurysm repair (FEVAR) and endovascular aneurysm repair (EVAR) with adjuncts (including chimneys and endo-anchors), as well as off label use of standard EVAR. The aim was to conduct a network meta-analysis (NMA) of published comparative outcomes. DATA SOURCES An electronic search was performed in Embase, MEDLINE, and the Cochrane Central Register of Controlled Trials (CENTRAL). These databases were interrogated using the PubMed interface and the Healthcare Databases Advanced Search (HDAS) interface developed by the National Institute of Health and Care Excellence. REVIEW METHODS Online databases were interrogated up to April 2020. Studies were included if they compared outcomes between at least two methods of repair for complex aneurysms (those with at least one adverse neck feature: absent/short neck, conicality, angulation, calcification, large diameter, and thrombus). The primary outcome measure was peri-operative death. Pre-registration was done in PROSPERO (CRD42020177482). RESULTS The search identified 24 observational studies and 7854 patients who underwent OSR, FEVAR, off label EVAR, or chimney EVAR. No comparative studies included EVAR with endo-anchors. NMA was performed on 23 studies that reported outcomes of aneurysms with short/absent infrarenal neck. Compared with OSR, off label EVAR (relative risk [RR] 0.10, 95% confidence interval [CI] 0.01 - 0.41) and FEVAR (RR 0.62, 95% CI 0.32-0.94) were associated with lower peri-operative mortality. This difference was not seen at the midterm follow up (30 months). Compared with OSR, FEVAR was associated with a lower peri-operative myocardial infarction (MI) rate (RR 0.37, 95% CI 0.16 - 0.62) but a higher midterm re-intervention rate (hazard ratio 1.65, 95% CI 1.04 - 2.66). All studies had a "moderate" or "high" risk of bias. Confidence in the network findings (GRADE) was generally "low". CONCLUSION This NMA demonstrated a peri-operative survival benefit for off label EVAR and FEVAR compared with OSR, potentially due to reduced risk of MI. FEVAR carries a greater midterm re-intervention risk than OSR, with potential implications for cost effectiveness. There is paucity of comparative data for cases with adverse neck features other than short length.

Abstract
OBJECTIVE Perform a systematic review and meta-analysis of the outcomes of physician modified endografts (PMEG) for treatment of thoraco-abdominal (TAAA) and complex abdominal aortic aneurysm (C-AAA) repair. METHODS We searched MEDLINE, CENTRAL, Web of Science Core Collection, Scielo and Open Grey databases from inception to July 2021 for studies reporting on outcomes of PMEGs for TAAA or C-AAA repair. A systematic review was conducted (protocol CRD42021267856) and data were pooled using a random-effects model of proportions. The outcomes analyzed were major adverse events at 30-days [30-day mortality, myocardial infarction, respiratory failure requiring prolonged ventilation (>24h or re-intubation), renal failure requiring dialysis, bowel ischemia requiring surgery, major stroke or definitive paraplegia]; technical success; 30-day mortality; ruptures; spinal cord ischemia; endoleaks; re-interventions and target vessel patency. RESULTS Twenty studies were included. Overall study quality assessment was found to be low. Overall, 909 PMEGs were reported and analyzed. Regarding aneurysm location (n=867), 222 patients had extent I-III TAAAs and 645 had C-AAA or extent IV TAAA. Regarding presentation, 14 studies reported if the patients were treated in an elective or urgent setting (n=782 patients). Overall, 500 (63.9%) patients were treated in an elective setting and 282(36.1%) in an urgent setting. Major adverse events (at thirty-days) occurred in 15.5% of patients (95%CI:10.8;20.8;I2=63%,135/832cases), being 11.6%(95%CI:8.1;15.7;I2=0%,23/280 cases) for elective patients and 24.6% for urgent (95%CI:14.1;36.6;I2=65%,50/192cases). Overall technical success was 97.2%(95%CI:95.4;98.7;I2=0%,587/611cases), being 98.0%(95%CI:92.1;100;I2=0%,106/113cases) for extent I-III TAAAs and 99.4%(95%CI:97.5;100;I2=0%,317/324cases) for C-AAA and extent IV TAAAs. Regarding technique, technical success was 96.1% for FEVAR (95%CI:93.2;98.4;I2=0%,313/329cases) and 99.8% for F/B-EVAR (95%CI:99.8;100;I2=0%,17/18 cases). CONCLUSION Physician modified fenestrated or branched grafts for endovascular aortic repair seems feasible and safe in the short-term follow-up. However, the quality of the available data is low which highlights the need for better and more accurate data regarding this technique.

Outcomes of off-the-shelf multibranched stent grafts with intentional occlusion of directional branches using endovascular plugs during endovascular repair of complex aortic aneurysms. J Vasc Surg 2022; 75:1142-1150.e4.

Abstract
OBJECTIVE To evaluate the technique and outcomes of intentional occlusion of directional branches (DBs) using endovascular plugs during branched endovascular aortic repair using off-the-shelf Zenith t-Branch thoracoabdominal (TAAA) stent grafts. METHODS We reviewed the clinical data and outcomes of all consecutive patients treated by branched endovascular aortic repair using off-the-shelf Zenith t-Branch TAAA stent-graft (Cook Medical, Bloomington, Ind) in seven academic centers from 2013 to 2019. All patients had at least one DB intentionally occluded using extension of the branch with balloon or self-expandable covered stent, followed by placement of endovascular plugs. Intentional occlusion was indicated in patients with variations in the normal four-vessel renal-mesenteric anatomy, pre-existing dialysis, or in those who failed catheterization of a target vessel. End points were 30-day/in-hospital mortality, major adverse events, secondary interventions, target artery (TA) patency, TA instability, and patient survival. RESULTS There were 100 patients, 65 male and 35 female, with median age of 71 years (interquartile range [IQR], 66-75 years). Of these, 31 patients (31%) had urgent/emergent operations for symptomatic/contained ruptured aneurysms. The median aneurysm diameter was 72 mm (IQR, 61-85 mm). A total of 290 renal-mesenteric arteries were incorporated with a median of three (IQR, 3-3) vessels/patient. Indications for DB occlusion were less than four suitable renal-mesenteric targets in 84 patients or pre-existing dialysis and inability to catheterize a target vessel in eight patients each. There were 110 DBs occluded by vascular plugs, including 48 celiac axis, one superior mesenteric artery, and 61 renal DBs. Thirty-day/in-hospital mortality was 10%, including 9% for elective and 13% for urgent/emergent procedures. Major adverse events occurred in 44 patients (44%), including acute kidney injury in 19 patients (19%), estimated blood loss >1 L in 12 patients (12%), respiratory failure and new onset dialysis in six patients (6%) each, bowel ischemia in five patients (5%), and myocardial infarction and paraplegia in two patients (2%) each. The median follow-up was 5 months (range, 1-13 months). Eighteen patients (18%) required secondary interventions, none for problems related to the occluded DB. There were no endoleaks related to the occluded DB. At 2 years, primary and secondary patency and freedom from TA instability were 93% ± 3%, 97% ± 2%, and 91% ± 4%, respectively. Freedom from secondary interventions and patient survival were 75% ± 6% and 63% ± 7%, respectively. CONCLUSIONS Intentional occlusion of DBs using endovascular plugs allows versatile use of a four-vessel off-the-shelf multi-branched TAAA stent graft in patients with variations in the normal renal and mesenteric anatomy or when technical difficulties prevent successful target vessel stenting. There were no endoleaks or secondary interventions associated with the occluded DB.

Female sex is associated with worse outcomes following complex fenestrated or branched endovascular aortic repair. Ann Vasc Surg 2022; 87:113-123. [PMID: 35339593 DOI: 10.1016/j.avsg.2022.03.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2022] [Revised: 03/09/2022] [Accepted: 03/11/2022] [Indexed: 11/17/2022]
Abstract
INTRODUCTION Sex-related discrepancies after standard endovascular aneurysm repair (EVAR) are noted to disproportionally affect females. A growing body of literature suggests similar disparities may extend to complex fenestrated or branched endovascular aneurysm repair (FBEVAR). However, recent examination of complex FBEVAR by a consortium of high-volume centers noted equivalent mortality among sexes. Whether similar results extend to non-trial data is unknown. METHODS We examined all juxta-renal through type IV thoraco-abdominal aneurysms (sealing zones 6-8) who underwent elective FBEVAR within the Vascular Quality Initiative (VQI) database from January 2012 to December 2020. Urgent, symptomatic, ruptured, and staged cases were excluded, as were parallel stent grafts. Demographics, comorbid conditions, and technical factors were compared between sexes. Univariate analysis with Wilcoxon ranked sum tests and Chi-square tests of proportion were performed, followed by multivariate logistic regression for failure of target vessel technical success, reintervention, complications, and in-hospital mortality. RESULTS Our analysis included 1521 patients, 1180 males (77.6%) and 341 females (22.4%). There were noted differences in pre-operative demographics, medical optimization, and technical aspects of the procedure. However, no difference was noted in proximal or distal sealing stents, number of fenestrations, or immediate endoleaks. On multi variate logistic regression, female sex was an independent predictor of failure of target vessel technical success (OR 3.339, 95% CI: 2.173-5.132, p<.001), reintervention (OR 2.192, 95% CI: 1.304-3.683, p=.003), complications (OR 1.747, 95% CI: 1.282-2.381, p<.001), and in-hospital mortality (OR 2.836, 95% CI: 1.510-5.328, p=.001). CONCLUSION Females suffer worse outcomes after FBEVAR despite similar extent of disease, number of fenestrations, and incidence of immediate endoleak. Notable discrepancies were higher rates of COPD and lower rates of pre-operative aspirin, statin, and beta blocker therapy in females. Controlling for pre-operative demographics, female sex remained an independent predictor of worse outcomes. These discrepancies warrant further examination and should impact case planning for female patients undergoing complex aortic aneurysm repair.

Abstract
OBJECTIVE Aortic neck anatomy has a significant impact on the complexity of endovascular aortic aneurysm repair (EVAR), with concern that neck characteristics outside of instructions for use (IFU) may result in worse outcomes. Therefore, this study determined the impact of neck characteristics outside of IFU on perioperative and one-year outcomes and mid-term survival after EVAR. METHODS We identified all patients undergoing elective infrarenal EVAR from December 2014 to May 2020 in the Vascular Quality Initiative database. Neck characteristics outside of IFU were determined based the specific device IFU neck characteristics (Neck diameter, length, and angulation). Patients without one-year follow-up were excluded for the 1-year outcomes analyses (n=6,138 (40%)). We used multivariable adjusted logistic regression and Cox proportional hazard models to identify the independent associations between neck characteristics outside of IFU and our outcomes. RESULTS Of the 15,448 patients identified, 22.1% had neck characteristics outside of IFU, including 6.6% with a infrarenal angle, 6.8% with a neck length, 10.4% with a neck diameter, and 1.1% with a suprarenal angulation outside of IFU. Of these, 2.4% had more than one neck characteristic outside of IFU. Patients with neck characteristics outside of IFU were more often female (27.9% vs. 15.0%, P<.001) and were older (median age 75 vs. 73, P<.001). EVAR patients with neck characteristics outside of IFU had higher rates of type Ia endoleaks at completion (4.8% vs. 2.5%, P<.001), perioperative mortality (1.2% vs. 0.6%, P<.001), one-year sac expansion (7.1% vs. 5.3%, P=.017), and one-year reinterventions (4.4% vs. 3.2%, P=.03). In multivariable adjusted analyses, neck characteristics outside of IFU were independently associated with type Ia completion endoleaks (OR 1.6, [1.3-2.0], P<.001), perioperative mortality (OR 1.8; [1.2-2.7]; P=.005), one-year sac expansion (OR 1.4; [1.0-1.8]; P=.025) and one-year reinterventions (OR 1.4; [1.0-1.9]; P=.039). Unadjusted mid-term survival was lower for patients with neck characteristics outside of IFU than for patients without (5-year survival 84.0% vs. 86.7%, log-rank<.001). However, after adjustment, survival was similar for patients with neck characteristics outside of IFU to those within (HR: 1.1; [1.0-1.3]; P=.22). CONCLUSION Neck characteristics outside of IFU are independently associated with completion type Ia endoleaks, perioperative mortality, one-year sac expansion and one-year reinterventions among patients undergoing elective EVAR. These results indicate that continued effort is needed to improve the proximal seal in patients with neck characteristics outside of IFU undergoing EVAR. Also, in patients with severe hostile neck characteristics, alternative approaches such as open repair, use of a fenestrated or branched device, or endoanchors should be considered.

Physician-modified endografts are associated with a survival benefit over parallel grafting in thoracoabdominal aneurysms. J Vasc Surg 2022; 76:318-325.e4.

Abstract
OBJECTIVE Physician-modified endografts (PMEG) and parallel grafting (PG) are important techniques for endovascular repair of complex aortic aneurysms using off-the-shelf devices. However, there is little data regarding the relative efficacy and outcomes of these techniques in thoracoabdominal extent aneurysms. This study sought to compare outcomes of PG and PMEG across different extents of thoracoabdominal aneurysms to which they can be employed. METHODS The SVS VQI TEVAR/Complex EVAR module was queried for all patients undergoing repair of an unruptured, thoracoabdominal aneurysm (TAAA, Extents I-IV) years 2012-2020; aneurysm types were defined by repair extent as determined by proximal and distal seal zones. Patients were differentiated based on whether they received repair with a physician-modified endograft (PMEG) or parallel grafting technique (PG). The primary outcomes for this study were overall survival and freedom from aneurysm/procedure-related mortality at 1-year determined via Kaplan-Meier analysis, with Cox hazard regression analysis conducted to examine the independent association of repair modality with primary outcomes. RESULTS 813 patients met inclusion criteria (TAAA I-III 362, TAAA IV 451; 426 PG, 387 PMEG). PMEG repairs were performed at centers with a nearly 2-3-fold higher annual volume of endovascular TAAA repairs. Type Ia endoleaks were reduced with PMEG repair, most significantly in TAAA IV (TAAA I-III: 2.2% PMEG vs. 10% PG, p = 0.2; TAAA IV: 1.2% PMEG vs. 21.6% PG, p <0.001). Thoracoabdominal repairs demonstrated improved survival at 1-year with PMEG devices, significant for TAAA I-III repairs (TAAA I-III: PMEG 85% vs. PG 74%, p = 0.01; TAAA IV: 84% PMEG vs. PG 78%, p = 0.08). Freedom from aneurysm/procedure-related mortality was also improved with PMEG repairs, remaining significant at 1-year in the case of TAAA IV (TAAA I-III: PMEG 94% vs. PG 86%, p = 0.06; TAAA IV: PMEG 94% vs. PG 88%, p = 0.02). PMEG demonstrated reductions in several measures of post-operative morbidity, including stroke/death, MACE, and post-operative complications. In multivariate analysis, repair modality was not associated with either primary outcome, rather, several perioperative complications conveyed the greatest hazard for both primary outcomes across repair extents. CONCLUSIONS Survival after endovascular TAAA repair is improved with the use of PMEG compared to PG. Several key factors of this study demonstrate the shortcomings of parallel grafting in complex aneurysm repair, namely high rates of critical endoleaks, the need for adjunctive access sites, and an increase in perioperative complications that influence longer-term outcomes.

Abstract
Stents are a widely-used device to treat a variety of cardiovascular diseases. The purpose of this review is to explore the application of regenerative medicine principles into current and future stent designs. This review will cover regeneration-relevant approaches emerging in the current research landscape of stent technology. Regenerative stent technologies include surface engineering of stents with cell secretomes, cell-capture coatings, mimics of endothelial products, surface topography, endothelial growth factors or cell-adhesive peptides, as well as design of bioresorable materials for temporary stent support. These technologies are comparatively analyzed in terms of their regenerative effects, therapeutic effects and challenges faced; their benefits and risks are weighed up for suggestions about future stent developments. This review highlights two unique regenerative features of stent technologies: selective regeneration, which is to selectively grow endothelial cells on a stent but inhibit the proliferation and migration of smooth muscle cells, and stent-assisted regeneration of ischemic tissue injury.

Abstract
Thoracoabdominal aneurysms pose technical challenges for endovascular repair due to involvement of visceral and renal vessels. We report a case series of four patients diagnosed with thoracoabdominal aneurysm who underwent complex endovascular repair with Fenestrated Device and chimney grafts (FEVARCh). FEVARCh is a technically feasible approach for repair of thoracoabdominal aneurysms that involve renal, superior mesenteric, and celiac arteries for patients not appropriate for open surgical repair. Further studies are needed to understand the implications of resultant Type 1a endoleaks and strategies to minimize the displacement of the main body graft with adjunct chimneys.

Abstract
OBJECTIVE Recent guidelines recognize the role of chimney endovascular aneurysm repair (ChEVAR) in the treatment of complex aortic disorders. The optimal configuration and number of visceral vessels that can be incorporated is still controversial. We aim to review outcomes from a multi-institutional decade-long experience with ChEVAR. METHODS Patients undergoing ChEVAR with multiple (≥2) chimney branches were selected from a prospectively maintained database at the two academic university hospitals. All patients were poorly suited for fenestrated or branched endograft repair (F/BEVAR) and deemed poor-risk for open surgery. RESULTS Forty-nine multiple ChEVAR were performed in 44 men and 5 women, with complete outcome data at a mean follow-up of 18 months. Overall, 2 patients died during follow-up (4%) with no aneurysm-related mortality and two ruptures after ChEVAR (4.1%) due to a type Ib endoleak from iliac limb pullout and persistent gutter-flow, both repaired with endovascular means. No stroke or spinal cord ischemia was noted during the follow-up period. Reintervention was undertaken in eight patients (16.3%) with five reinterventions for persistent gutter-flow and four chimney graft-associated. Three-vessel ChEVAR was performed in 16 patients, with two-vessel ChEVAR in 33 patients for a total of 114 chimney branches (mean 2.3 chimneys per patient). There were 21 superior mesenteric artery (SMA), 45 right renal, 46 left renal artery (LRA), and two accessory LRA chimneys placed. Antegrade configuration of chimney branches was chosen in 43 patients (88%). There were no significant differences between three-vessel and two-vessel ChEVAR upon univariate analysis in aneurysm size (65.6 vs 60.5 mm; p = 0.059), iliac diameter (7.3 vs 7.1 mm; p = 0.85), or endograft oversizing (30 vs 32.5%; p = 0.43). Three-vessel ChEVAR was associated with a larger aneurysm neck diameter (28.4 vs 25.0 mm; p = 0.021), shorter native infrarenal neck (0.5 vs 3.37 mm; p = 0.002) as well as longer seal zone (36.33 vs 22.67 mm; p = 0.005) compared with two-vessel ChEVAR. At follow-up, there were no significant differences in gutter area between three-vessel and two-vessel ChEVAR (18.9 vs 15.7 mm3; p = 0.73) nor the rate of persistent gutter-flow (12.5 vs 9.1%; p = 0.71). CONCLUSION Reintervention to multiple chimney grafts and for persistent gutter-flow is higher compared to single chimneys and demands close surveillance. However, based upon this combined transantlantic experience, we believe multiple ChEVAR provides a reasonable and safe option for complex aortic aneurysm repair when open or custom endografts are not available or indicated based on their Instructions For use, even when triple chimney grafts are required. The optimal configuration for multiple ChEVAR still warrants further study, although theoretical preliminary advantages may exist for a combination of antegrade and retrograde chimneys.

Abstract
Thoraco-abdominal aneurysm (TAA) repair carries a significant risk of spinal cord infarction. The latter results from irreversible changes in the spinal cord arterial network, e.g., sacrifice of the segmental arteries. Intra-operative neurophysiology with somatosensory and especially motor evoked potential (SEP and MEP respectively) monitoring, has emerged as an effective tool to assess the efficiency of the collateral blood flow, detect reversible spinal cord ischemia and guide the peri-operative multidisciplinary management to prevent postoperative paraplegia. The main roles of such monitoring include diagnosis of spinal cord vs peripheral limb ischemia, titration of mean arterial pressure during aortic clamping, the guidance of selective re-implantation of critical segmental arteries, and management of hemodynamics in the immediate postoperative period. In addition, manipulation of the aortic arch and proximal descending aorta, adds the risk of cerebral infarction from both low flow state and/or thromboembolic events. As such, EEG monitoring may be a useful add-on for either assessment of the efficiency of cerebral cooling as a neuroprotective method and/or for detection and treatment of reversible cerebral ischemia. This chapter presents the multimodality approach to open TAA monitoring as a versatile tool for the prevention of devastating postoperative neurologic deficits.

Abstract
OBJECTIVE We evaluate nationwide perioperative outcomes of complex EVAR and assess the volume-outcome association of complex EVAR. SUMMARY OF BACKGROUND DATA Endovascular treatment with fenestrated (FEVAR) or branched (BEVAR) endografts is progressively used for excluding complex aortic aneurysms (complex AAs). It is unclear if a volume-outcome association exists in endovascular treatment of complex AAs (complex EVAR). METHODS All patients prospectively registered in the Dutch Surgical Aneurysm Audit who underwent complex EVAR (FEVAR or BEVAR) between January 2016 and January 2020 were included. The effect of annual hospital volume on perioperative mortality was examined using multivariable logistic regression analyses. Patients were stratified into quartiles based on annual hospital volume to determine hospital volume categories. RESULTS We included 694 patients (539 FEVAR patients, 155 BEVAR patients). Perioperative mortality following FEVAR was 4.5% and 5.2% following BEVAR. Postoperative complication rates were 30.1% and 48.7%, respectively. The first quartile hospitals performed <9 procedures/yr; second, third, and fourth quartile hospitals performed 9-12, 13-22, and ≥23 procedures/yr. The highest volume hospitals treated the significantly more complex patients. Perioperative mortality of complex EVAR was 9.1% in hospitals with a volume of < 9, and 2.5% in hospitals with a volume of ≥13 (P = 0.008). After adjustment for confounders, an annual volume of ≥13 was associated with less perioperative mortality compared to hospitals with a volume of < 9. CONCLUSIONS Data from this nationwide mandatory quality registry shows a significant effect of hospital volume on perioperative mortality following complex EVAR, with high volume complex EVAR centers demonstrating lower mortality rates.

Abstract
OBJECTIVES Ruptured and symptomatic juxtarenal and paravisceral aneurysms present technical challenges during endovascular repair. We sought to compare physician modification and fenestrated (PMEG) versus chimney/periscope/snorkel (CHIMPS) repair techniques for the treatment of ruptured and symptomatic paravisceral and juxtarenal aortic aneurysms (r/sPJAA). METHODS Patients in the thoracic and complex endovascular aneurysm module of the Vascular Quality Initiative (VQI) national registry undergoing CHIMPS and PMEG for r/sPJAA were included. Patients who underwent thoracic aneurysm repair with only celiac intervention or who had coverage or occlusion only of one renal or visceral branch vessel were excluded. One-year mortality was the primary outcome. Secondary outcomes included peri- and postoperative endoleak, hospital and ICU length of stay, reintervention, and other local and systemic complications. RESULTS A total of 81 CHIMPS and 47 PMEG patients were identified. Patients undergoing PMEG were more frequently symptomatic, had a history of CHF and were taking aspirin, statin and P2Y12 antiplatelet medications. Patients undergoing CHIMPS presented more frequently with rupture. There was no significant survival advantage for CHIMPS over PMEG patients (P = 0.5). There were no apparent long-term differences in the numbers of endoleaks or in the rates of subsequent reinterventions between the two groups. CONCLUSIONS It does not appear that the procedure type (CHIMPS versus PMEG) is associated with postoperative survival in patients with r/sPJAA. Not surprisingly, survival is associated with postoperative complications, particularly myocardial infarction and intestinal ischemia. Further research should evaluate reasons for failure to rescue from and the impact of postoperative complications on the postoperative survival after endovascular repair of r/sPJAA.

Abstract
INTRODUCTION In one-third of all abdominal aortic aneurysms (AAAs), the aneurysm neck is short (juxtarenal) or shows other adverse anatomical features rendering operations more complex, hazardous and expensive. Surgical options include open surgical repair and endovascular aneurysm repair (EVAR) techniques including fenestrated EVAR, EVAR with adjuncts (chimneys/endoanchors) and off-label standard EVAR. The aim of the UK COMPlex AneurySm Study (UK-COMPASS) is to answer the research question identified by the National Institute for Health Research Health Technology Assessment (NIHR HTA) Programme: 'What is the clinical and cost-effectiveness of strategies for the management of juxtarenal AAA, including fenestrated endovascular repair?' METHODS AND ANALYSIS UK-COMPASS is a cohort study comparing clinical and cost-effectiveness of different strategies used to manage complex AAAs with stratification of physiological fitness and anatomical complexity, with statistical correction for baseline risk and indication biases. There are two data streams. First, a stream of routinely collected data from Hospital Episode Statistics and National Vascular Registry (NVR). Preoperative CT scans of all patients who underwent elective AAA repair in England between 1 November 2017 and 31 October 2019 are subjected to Corelab analysis to accurately identify and include every complex aneurysm treated. Second, a site-reported data stream regarding quality of life and treatment costs from prospectively recruited patients across England. Site recruitment also includes patients with complex aneurysms larger than 55 mm diameter in whom an operation is deferred (medical management). The primary outcome measure is perioperative all-cause mortality. Follow-up will be to a median of 5 years. ETHICS AND DISSEMINATION The study has received full regulatory approvals from a Research Ethics Committee, the Confidentiality Advisory Group and the Health Research Authority. Data sharing agreements are in place with National Health Service Digital and the NVR. Dissemination will be via NIHR HTA reporting, peer-reviewed journals and conferences. TRIAL REGISTRATION NUMBER ISRCTN85731188.

Abstract
OBJECTIVE Type 3 Endoleaks (T3EL) following complex EVAR (c-EVAR) for abdominal aortic aneurysm have been historically difficult to study due to their relative rarity. Previous studies within standard infrarenal EVAR have found an association between T3EL and decreased survival. This study aims to evaluate the occurrence of T3EL in a national multicenter cohort, identify potential procedural characteristics associated with T3EL development, and determine their impact on clinical outcomes in c-EVAR. METHODS A retrospective cohort review was conducted of elective c-EVAR for non-ruptured aneurysms within the Vascular Quality Initiative (VQI) between January 2010 and March 2020. The VQI standards define c-EVAR as suprarenal or pararenal AAA repaired with any thoracoabdominal repairs, fenestrated/branched repairs, parallel stent repairs, custom manufactured devices, and physician modified endografts. End-points assessed were rates of T3EL within c-EVAR, and impact of T3EL on reintervention and survival. Index endoleaks were defined as endoleaks discovered during index hospitalization. Incident endoleaks were defined as new endoleaks, that were not present at index hospitalization, discovered at follow-up. RESULTS 4,070 c-EVAR cases were identified between January 2010 and March 2020, of which, 2,656 (65.2%) had appropriate follow-up data. Half the cohort had a modified or custom graft (n=2,055/4,070, 50.5%). Branches were employed in 3,687 patients (90.5%), while fenestrations and chimney techniques were documented in 13% (n=533) and 15.1% (n=613) respectively . The rate of index T3EL was 4.1% (n=167), and the rate of incident T3EL at follow-up was 0.04% (n=1). Devices categorized as either custom or physician modified were utilized more frequently in patients with index T3EL (78.4%, n=131/167) compared to patients without index T3EL (49.2%, n=1,924/3,903) (p<0.001). Compared to those without T3EL, the presence of index T3EL was not statistically associated with increased aortic reinterventions or increased mortality. CONCLUSIONS T3EL in c-EVAR remain relatively uncommon and are identified predominately at index hospitalization. Development of T3EL was associated with higher device modularity and modification, which suggests that as device technologies continue to advance and become more intricate the occurrence of T3EL may persist and continue to require evaluation. In this study, the presence of T3EL did not appear to have a statistically significant relationship with aortic reinterventions or survival, however these findings are not definitive due to low event rate numbers and high potential for Type 2 errors. Amid the theoretical risk of device fatigue and degeneration, continued evaluations of large cohorts at extended follow-up intervals and diligent reporting remain paramount.
