Abstract
INTRODUCTION To confirm real-world clinical practice results reported with anatomically fixed bifurcated endograft, a physician-initiated study was designed-AFX2-LIVE registry. MATERIALS AND METHODS From November 2019 to August 2021, investigators enrolled all consecutive patients treated with AFX2 (Endologix Inc., Irvine, CA, USA) endograft. Patients with abdominal aortic aneurysms (AAAs), penetrating aortic ulcers (PAU), and isolated infrarenal aortic dissections were included. Clinical and anatomical data, including baseline, intraoperative, and in-hospital details, as well as follow-up data, were collected in an anonymized prospectively compiled database. The primary endpoint of this study was to evaluate the technical and clinical success of endovascular aortic repair (EVAR) using AFX2 endograft. RESULTS A total of 535 patients were enrolled from 43 Italian and Spanish centers and analyzed according to the protocol. Four hundred eighty-nine patients were male (91.4%), with a mean age of 75±8.92 years (range 52-94). Four hundred sixty-six patients (87.1%) were treated for AAA, 49 (9.3%) for PAU, and 20 (3.6%) for isolated abdominal aortic dissection. A proximal extension was needed in 48% of the cases. Assisted technical success was achieved in all but one patient (99.8%). At 30 days follow-up, no AAA-related deaths were recorded, and nine patients (1.6%) required reintervention. At a mean follow-up period of 15.22±13.65 (range 1-53) months, data were available for 479 patients (89.5%). Clinical success was achieved in 98.2% (95% confidence interval [CI]: 96.4-99.1) at 3 months, 93.9% (95% CI: 90.1-96.1) at 1 year, and 74.1% (95% CI: 62.8-82.4) at 4 years follow-up. The estimated freedom from all-cause mortality was 97.7%, 93.4%, 81.6%, 77.5%, and 70.9%, and freedom from AAA-related mortality was 100%, 99.6%, 99.6%, 99.6%, and 97.3% at 3, 12, 24, 36, and 48 months, respectively. Twenty reinterventions (3.7%) were required in 19 patients, of which 3 late open conversions (0.6%) were performed, and 2 AAA-related deaths were observed. CONCLUSION This study demonstrated excellent clinical and technical success rates of EVAR with anatomically fixed endografts, providing valuable insights into real-world clinical outcomes. CLINICAL IMPACT The AFX2-LIVE study could have a significant impact by providing robust evidence supporting the effectiveness and safety of EVAR using bifurcated endografts with anatomical fixation in real-world clinical practice, ultimately leading to improved outcomes and enhanced patient care in the management of abdominal aortic pathologies.

Choi E, Kwon TW. Endovascular Treatment versus Open Surgical Repair for Isolated Iliac Artery Aneurysms. Vasc Specialist Int 2024; 40:31. [PMID: 39328043 PMCID: PMC11437323 DOI: 10.5758/vsi.240041] [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: 04/19/2024] [Revised: 06/27/2024] [Accepted: 07/16/2024] [Indexed: 09/28/2024] Open
Abstract
Purpose Endovascular treatment (EVT) has been shown to be effective and safe for isolated iliac artery aneurysms (IAAs). However, concerns remain regarding the lack of consideration to recent advances in perioperative care and surgical techniques, as well as a significant number of re-interventions with EVT. This study compares the outcomes of open surgical repair (OSR) and EVT using recent clinical data. Materials and Methods This retrospective, single-center study included patients who underwent OSR or EVT for isolated degenerative IAAs between January 2007 and December 2018. Primary outcomes were procedure time, number of transfusions during admission, length of hospital stay, complications, and number of preserved internal iliac arteries. Secondary outcomes included all-cause and aneurysm-related mortality, and re-intervention rates. Results Fifty-eight consecutive patients underwent treatment for isolated IAAs (25 underwent OSR and 33 underwent EVT), with a median follow-up of 75 months (range: 39-133 months). Baseline characteristics were similar between the groups, except for a lower mean age in the OSR group than in the EVT group (66.0±8.2 vs. 73.1±8.6, P=0.003). Both groups had a mild risk of comorbidity severity score. Early complications (within 30 days of the procedure) occurred more frequently in the OSR group, though not statistically significant (24.0% vs. 6.1%, P=0.07). Late complications, including sac expansion and thrombotic occlusion, were significantly more common in the EVT group (15.2% vs. 0%, P=0.04). Re-intervention rate was higher in the EVT group but not statistically significant (9.1% vs. 4.0%, P=0.44). No significant differences were observed in major adverse cardiovascular events and mortality between the groups (P=0.66 and P=0.27), and there were no aneurysm-related deaths. Conclusion For patients with mild risk factors, EVT does not offer a survival or re-intervention advantages over OSR in the treatment of isolated IAAs. However, EVT is associated with an increased risk of late complications. Although larger randomized studies are necessary, OSR may be considered the first-line treatment for isolated IAAs in younger and mild-risk patients.

Abstract
PURPOSE Prevalence of abdominal aortic aneurysms (AAAs) increases with age. Previous trials confirm that elective endovascular aneurysm repair (EVAR) is an effective intervention for AAA. However, few elderly patients were recruited into randomized trials, whereas in contemporary clinical practice, elective repair is commonly performed on octogenarians. We evaluated the safety and outcome of elective EVAR in elderly patients to inform clinical practice and vascular service provision. METHODS A systematic review and meta-analysis of studies reporting risk of complications and death in patients undergoing elective EVAR was performed (PROSPERO CRD: 42022308423). Observational studies and interventional arms of randomized trials were included if the outcome rates or raw data were provided. Primary outcome was 30-day mortality. Secondary outcomes were longer-term mortality, 30-day major adverse events, and aneurysm-related mortality. Primary and secondary outcomes were compared between octogenarians and non-octogenarians. Exclusion criteria were emergency procedures, non-infrarenal aneurysms, and lack of octogenarian data. RESULTS A total of 41 studies were eligible from 10 099 citations, including 10 national and 5 international registries, 26 retrospective studies, and our own prospective cohort. The analysis included 208 997 non-octogenarians (mean age=70.19 [SD=0.62]) and 106 188 octogenarians (mean age=83.75 [SD=0.35]). The 30-day mortality post-elective EVAR was higher in octogenarians (1.08% in non-octogenarians, 2.31% in octogenarians, odds ratio [OR]=2.27 [2.08-2.47], p<0.0001). Linear regression demonstrated a 0.83% increase in 30-day mortality for every 10-year age increase above 60 years old. Mortality for octogenarians increased significantly during follow-up: 11.35% (OR=1.87 [1.65-2.13], p<0.001), 22.80% (OR=1.89 [1.52-2.35], p<0.001), 32.00% (OR=1.98 [1.66-2.37], p<0.001), 47.53%, and 51.08% (OR=2.40 [1.90-3.03], p<0.001) at 1-through-5-year follow-up, respectively. The 30-day major adverse events after elective EVAR were higher in octogenarians (OR=1.75-2.83, p<0.001). CONCLUSIONS Octogenarians experience higher but acceptable peri-operative morbidity and mortality compared with younger patients. However, 3-year to 5-year survival is very low among octogenarians. Our findings challenge the notion of routine intervention in elderly patients and support very careful selection for elective EVAR. Many octogenarians with peri-threshold (<6 cm) AAAs may derive no benefit from EVAR due to limited 3-year to 5-year overall survival and low risk of aneurysm rupture with conservative management. An adjusted threshold for intervention in octogenarians may be warranted. CLINICAL IMPACT Octogenarians with infra-renal AAA are increasingly managed with elective EVAR. Previous studies have demonstrated that EVAR is safer than open repair for octogenarians, with lower peri-operative mortality and major adverse events. However, randomised trials, on which much of contemporary evidence is based, recruited a relatively younger population of participants. This systematic review and meta-analysis provides a contemporary synthesis of the literature comparing outcomes in octogenarians to younger patients. The results of this analysis, together with low rupture rates amongst octogenarians in existing literature, question the benefit of routine elective intervention for peri-threshold aneurysms and an adjusted threshold for intervention in octogenarians may be warranted.

Early and Mid-Term Results of Endovascular Aneurysm Repair with the Cordis Incraft Ultra-Low Profile Endograft: A High-Volume Center Experience. J Clin Med 2024; 13:5413. [PMID: 39336900 PMCID: PMC11432392 DOI: 10.3390/jcm13185413] [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: 07/04/2024] [Revised: 08/09/2024] [Accepted: 09/09/2024] [Indexed: 09/30/2024] Open
Abstract
Background/Objectives: In recent years, manufacturers have developed new low-profile stent grafts to allow endovascular treatment of abdominal aortic aneurysms (AAA) in patients with small access vessels. We evaluated the early and mid-term outcomes of the Incraft (Cordis Corp, Bridgewater, NJ, USA) ultra-low profile endograft implantation in a high-volume single center. Methods: Between 2014 and 2023, 133 consecutive endovascular aneurysm repair (EVAR) procedures performed using the Incraft endograft were recorded in a prospective database. Indications included infrarenal aortic aneurysms, common iliac aneurysms, and infrarenal penetrating aortic ulcers. Mid-term results were analyzed using the Kaplan-Meier method. Results: During the study period, 133 patients were treated with the Cordis Incraft endograft, in both elective and urgent settings. The Incraft graft was the first choice for patients with hostile iliac accesses, a feature characterizing at least one side in 90.2% of the patients in the study cohort. The immediate technical success rate was 78.2%. The intraoperative endoleak rate was 51.9% (20.3% type 1 A, 0.8% type 1 B, and 30.8% type 2 endoleak). Within 30 days, technical and clinical success rates were both 99.3%; all type 1A and 1B endoleaks were resolved at the 30-day follow-up CT-angiogram. After a mean follow-up of 35.4 months, the actuarial freedom from the re-intervention rate was 96.0%, 91.1%, and 84.0% at 1, 3, and 5 years, respectively. The iliac leg patency rate was 97.1%, 94.1%, and 93.1% at 1, 3, and 5 years, respectively. No statistically significant differences were observed between hostile and non-hostile access groups, nor between the groups with grade 1, grade 2, and grade 3 access hostility. Conclusions: The ultra-low profile Cordis Incraft endograft represents a valid option for the endovascular treatment of AAA in patients with hostile iliac accesses. The procedure can be performed with high rates of technical and clinical success at 30 days and the rates of iliac branch occlusion observed during the follow-up period appear acceptable in patients with poor aorto-iliac outflow.

Abstract
INTRODUCTION Women are generally underrepresented in trials focusing on aortic aneurysm. Nevertheless, sex-related differences have recently emerged from several studies and registries. The aim of this research was to assess whether sex-related anatomical disparities existed in fenestrated and branched aortic repair candidates and whether these discrepancies could influence endovascular repair outcomes. METHODS Data from all consecutive patients treated during the 2008-2019 period within the Italian Multicenter fenestrated or branched endovascular aortic repair (F/BEVAR) Registry were included in the present study. Propensity matching was performed using a logistic regression model adjusted for demographic data and comorbidities to obtain comparable male and female samples. The selection model led to a final study population of 176 patients (88 women and 88 men) among the total initial cohort of 596. Study endpoints were technical and clinical success, overall survival, aneurysm-related death, and reintervention rates evaluated at 30 days and during follow-up. RESULTS Twenty-eight patients (15.9%) received urgent/emergent repair. In most of the cases (71.6%), women received treatment for extensive thoracoabdominal pathology (Crawford type I, II, or III aneurysm rather than type IV or juxta-pararenal) versus 46.6% of men (p=0.001). Female patients presented with more challenging iliac accesses with at least one side considered hostile in 27.3% of the cases (vs 13.6% in male patients, p=0.039). Finally, women had significantly smaller visceral vessels. Women had significantly worse operative outcomes, with an 86.2% technical success rate versus 96.6% in the male population (p=0.016). No differences were recorded in terms of 30-day reinterventions between men and women. The 5-year estimate of freedom from late reintervention, according to Kaplan-Meier analysis, was 85.6% in men versus 81.6% in women (p=ns). No aneurysm-related death was recorded during follow-up (median observational time, 23 months [interquartile range, 7-45 months]). CONCLUSION Women presented a significantly higher incidence of thoracoabdominal aneurysms, smaller visceral vessels, and more complex iliofemoral accesses, resulting in a significantly lower technical success after F/BEVAR. Further studies assessing sex-related differences are needed to properly determine the impact on outcomes and stratify procedural risks. CLINICAL IMPACT Women are generally underrepresented in trials focusing on aortic aneurysms. Aiming to assess whether sex may affect outcomes after a complex endovascular aortic repair, a propensity score selection was applied to a total population of 596 patients receiving F/BEVAR aortic repair with the Cook platform, matching each treated female patient with a corresponding male patient. Women presented more frequently a thoracoabdominal aneurysm extent, smaller visceral vessels, and complex iliofemoral accesses, resulting in significantly worse operative outcomes, with an 86.2% technical success versus 96.6% (p=0.016). No differences were recorded in terms of short-term and mid-term reinterventions. According to these results, careful and critical assessment should be posed in case of female patients receiving complex aortic repair, especially regarding preoperative anatomical evaluation and clinical selection with appropriate surgical risk stratification.

Abstract
OBJECTIVES To evaluate if ileo-psoas muscle size and visceral adipose tissue (VAT) can predict long-term survival after endovascular aneurysm repair (EVAR). METHODS Patients who underwent EVAR between 2004 and 2012 in a single centre were included. Total psoas muscle area (TPA), abdominal VAT area, subcutaneous adipose tissue (SAT), and total adipose tissue were measured on the preoperative CT. Primary endpoint was all-cause mortality. Values are presented as median and interquartile range or absolute number and percentage. Cox regression analyses were performed to assess the associations with mortality. RESULTS Two hundred and eighty-four patients could be included in the study. During a median follow-up of 8 (4-11) years, 223 (79.9%) patients died. Age (P ≤ .001), cardiovascular (P = .041), cerebrovascular (P = .009), renal diseases (P = .002), and chronic obstructive pulmonary disease (P ≤ .001) were independently associated with mortality. TPA was associated with mortality in a univariate (P = .040), but not in a multivariate regression model (P = .764). No significant association was found between mortality and TPA index (P = .103) or any of the adiposity measurements with the exception of SAT (P = .040). However, SAT area loss in a multivariate analysis (P = .875). CONCLUSIONS Assessment of core muscle size and VAT did not contribute to improving the prediction of long-term survival after EVAR. ADVANCES IN KNOWLEDGE The finding of this study contradicts the previously claimed utility of core muscle size and VAT in predicting long-term survival after EVAR.

Abstract
INTRODUCTION Perioperative myocardial ischemia (PMI) is a serious postoperative complication. Aortic operations represent an especially high-risk surgery concerning cardiac complications. This aim of this study was to analyse the clinical features of PMI after elective aortic aneurysm surgery. PATIENTS AND METHODS This study is a retrospective analysis of 863 patients who underwent elective aortic aneurysm surgery between 2005 and 2012 in the Department of Vascular and Endovascular Surgery of Heidelberg University Hospital with regard to PMI. The PMI diagnosis was based on a positive serum troponin diagnostic test. We evaluated the clinical course, time point of the diagnosis and features of diagnostics to characterise PMI. Moreover, we analysed the treatment options and management of the patients' discharge. RESULTS Thirty-one patients (3.6% of 863) with PMI after elective aortic aneurysm surgery were identified. Of these, 21 patients (67.7%) underwent open surgery and 10 patients (32.3%) received endovascular treatment. PMI was diagnosed in 24 patients (77%) during the first 3 days. More than half of these patients (16/31) were clinically asymptomatic. Electrocardiogram did not show pathological findings in 24 cases (77.4%). The first troponin measurement was not elevated in eight patients (25.8%). Drug therapy alone was used in 17 cases (54.8%) of PMI, coronary catheterisation was performed in 12 patients (38.7%) and two patients (6.5%) received aortocoronary bypass. Fourteen patients (45.1%) were discharged home and another 14 patients (44.1%) were transferred to another hospital or to a rehabilitation institution. Two patients died because of multi-organ failure. CONCLUSION PMI is not a rare complication after elective aortic surgery. The diagnosis of PMI can be challenging because of occult symptoms especially in a perioperative setting. Due to the potentially serious consequences, cardiac enzyme diagnostics should be initiated immediately if there is suspicion of PMI or routinely in defined at-risk patients after aortic surgery.

Abstract
BACKGROUND Patients with unruptured abdominal aortic aneurysm (AAA) at the surgical threshold may benefit from aneurysmal exclusion either by open surgery or endovascular repair. A patient decision aid (PtDA) could be useful to help patients and their surgeons choose between the 2 techniques. The aim of this study was to develop a shared medical decision support tool, in french language, for the surgical treatment of AAA. METHODS Following the steps recommended by the International Patient Decision Aids Standards, we carried out a qualitative study using semi-structured interviews with patients and vascular surgeons and focus group with patients to identify their main points of interest. After analyzing the interviews using grounded theory with independent double coding, the verbatims were discussed at a steering committee, at the end of which a prototype of the tool was created. RESULTS Four surgeons and 14 patients were interviewed. No new codes emerged from the last 2 interviews. At the end of the steering committee meeting, the information selected for inclusion in the PtDA tool were the definition of an AAA, a description of the 2 surgical techniques (approach, duration of operation), the main complications, the peri-operative mortality rate, and postoperative follow-up (length of hospital stay, monitoring frequency, and risk of re-intervention). It had to be produced on a synthetic paper format, with 6 illustrations and a simple vocabulary. CONCLUSIONS We developed a PtDA tool for use in a sharing decision making process with the patient during consultation with the vascular surgeon and the general practitioner. Further studies are needed to validate the tool and to test it in clinical practice.

Pirinen R, Laine MT, Mani K, Gunnarsson K, Wanhainen A, Sund R, Venermo M. The Outcome after Endovascular and Open Repair of Abdominal Aortic Aneurysms-A Binational Study Conducted between 1998 and 2017. J Clin Med 2024; 13:4449. [PMID: 39124716 PMCID: PMC11313620 DOI: 10.3390/jcm13154449] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2024] [Revised: 07/25/2024] [Accepted: 07/25/2024] [Indexed: 08/12/2024] Open
Abstract
Objective: We aimed to analyse patient outcomes following open (OAR) or endovascular repair (EVAR) of an abdominal aortic aneurysm (AAA) in Finland and Sweden from 1998 to 2017. Both intact and ruptured AAAs (rAAAs) were included in the analysis. Methods: Patient-level data from national registries in Finland and Sweden were analysed, pairing operations for intact and ruptured AAA repair with mortality data (date of death). All-cause mortality was the primary endpoint. Anonymized patient data from both countries were pooled, comprising a total of 32,324 operations. Ruptured and intact AAAs were considered separately. In total, EVAR was performed on 9619 intact AAAs and 1470 rAAAs, while OAR was performed on 13,241 intact AAAs and 7994 rAAAs. The patient's age, sex and the date of operation were obtained as demographic information. Cox regression and Kaplan-Meier analyses were used to evaluate long-term (10-year) survival after the treatment of AAA or rAAA with either modality. Kaplan-Meier analysis was performed in three different age groups (<65 years, 65-79 years and ≥80 years). Results: Considering all age groups together, the 1-, 3- and 10-year Kaplan-Meier survival rates after EVAR were 93.4%, 80.5% and 35.3%, respectively, for intact AAA repair and 67.2%, 55.9% and 22.2%, respectively, for rAAA repair. For OAR of intact AAAs, the 1-, 3- and 10-year Kaplan-Meier survival rates were 92.1%, 84.8% and 48.7%, respectively. The respective rates for OAR of rAAAs were 55.4%, 49.3% and 24.6%. In a Cox regression analysis, a more recent year of operation was associated with improved survival, and older age affected survival negatively for both intact and ruptured AAA repair. If patients survived the first 90 days after the operation, the survival after intact AAA repair was 13.5 years for those <65 years (general population: 18.0 years), and 7.3 years for those ≥80 years (general population: 7.9 years). After rAAA repair, the mean survival was 13.1 years for patients <65 years and 5.5 years for patients ≥80 years, respectively. Conclusions: The long-term survival of patients undergoing intact AAA treatment at the age of 80 or older is close to that of the general population, provided they survive the operation. Conversely, for patients younger than 65, the long-term survival is markedly worse. The long-term survival of AAA patients has improved over time. Open surgery is still a safe and effective option for young patients undergoing intact AAA repair. Our results support the ESVS guidelines recommendation of EVAR being the first-line treatment for patients with rAAA.

J Pers Med 2024; 14:759. [PMID: 39064014 PMCID: PMC11278265 DOI: 10.3390/jpm14070759] [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: 06/07/2024] [Revised: 07/08/2024] [Accepted: 07/15/2024] [Indexed: 07/28/2024] Open
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
BACKGOUND The number of endovascular abdominal aortic aneurysm repairs (EVARs) has surpassed the number of open surgical repair of AAAs worldwide with a great variety of endografts being available. The aim of this study is to conduct a systematic review of the literature and meta-analysis of studies reporting patients with infrarenal abdominal aortic aneurysm (AAA) subjected to EVAR with the Anaconda endograft. METHODS We performed a systematic review of multiple electronic databases for studies including patients with infrarenal AAA who were subjected to elective EVAR with Anaconda endograft exclusively. We conducted a proportional meta-analysis cumulating the results of the included studies. The endpoints were first month overall mortality, first and second-year survival after EVAR, AAA-related deaths, incidence of endoleaks, endograft migration, endograft occlusion, open conversion, and primary and secondary technical success. The mean value for each separate studied factor was calculated, and the respective percentage or incidence was extracted so that it can be compared to endograft outcome studies in the literature. We assessed the methodologic quality of studies by using the Briggs Institute critical appraisal tool. RESULTS Seven observational studies were found including 954 patients (males 91.9%, mean age 73.38 ± 6.97 years). The mean transverse diameter of AAAs was 56.83 ± 9.97 mm. The mean proximal aortic neck diameter and length were 23.06 ± 3.33 mm and 24.14 ± 12.16 mm, respectively. Increased aortic neck calcification and aortic neck thrombus were present in 12.5% of patients. The 30-day overall mortality post-EVAR was 1.3%, 1 and 2-year survival rates were 95.9% and 91.4%, respectively. The mean follow-up period in the studies was 46.59 ± 15.5 months. AAA-related mortality was 1.3%. Primary technical success was 97.9% and secondary success was 99.3%. Open conversion was required in 3.4% of all patients (0.6% during the primary operation [Prim. Op]). The most common endoleak was type II, reported in 17.4% of all patients. Early type Ia endoleak was reported in 1.5% of patients and late type Ia in 1.7%. Overall, 2 endoleaks type III and 1 type IV were reported. Endograft migration occurred in 1.7% of patients. Main body and/or one/both iliac legs thrombotic occlusion was found totally in 7.6% of patients (5 main body occlusions and 64 iliac leg occlusions). CONCLUSIONS The use of Anaconda endograft in electively treated patients with infrarenal AAAs presented good results with high technical success and low postoperative and mid-term complications, except for an increased incidence of stent-graft thrombosis, which seems to be the "Achilles heel" of the device.

Abstract
PURPOSE The impact of preoperative patent inferior mesenteric artery (IMA) on late outcomes following endovascular aneurysm repair (EVAR) remains unclear. This study aimed to investigate the specific influence of IMA patency on 7-year outcomes after EVAR. MATERIALS AND METHODS In this retrospective cohort study, 556 EVARs performed for true abdominal aortic aneurysm cases between January 2006 and December 2019 at our institution were reviewed. Endovascular aneurysm repairs performed using a commercially available device with no type I or type III endoleak (EL) during follow-up and with follow-up ≥12 months were included. A total of 336 patients were enrolled in this study. The cohort was divided into the patent IMA group and the occluded IMA group according to preoperative IMA status. The late outcomes, including aneurysm sac enlargement, reintervention, and mortality rates, were compared between both groups using propensity-score-matched data. RESULTS After propensity score matching, 86 patients were included in each group. The median follow-up period was 56 months (interquartile range: 32-94 months). The incidence of type II EL at discharge was 50% in the patent IMA group and 19% in the occluded IMA group (p<0.001). The type II EL from IMA and lumbar arteries was significantly higher in the patent IMA group than in the occluded IMA group (p<0.001 and p=0.002). The rate of freedom from aneurysm sac enlargement with type II EL was significantly higher in the occluded IMA group than in the patent IMA group (94% vs 69% at 7 years; p<0.001). The rate of freedom from reintervention was significantly higher in the occluded IMA group than in the patent IMA group (90% vs 74% at 7 years; p=0.007). Abdominal aortic aneurysm-related death and all-cause mortality did not significantly differ between groups (p=0.32 and p=0.34). CONCLUSIONS Inferior mesenteric artery patency could affect late reintervention and aneurysm sac enlargement but did not have a significant impact on mortality. Preoperative assessment and embolization of IMA might be an important factor for improvement in late EVAR outcomes. CLINICAL IMPACT The preoperative patency of the inferior mesenteric artery was significantly associated with a higher incidence of sac enlargement and reintervention with type II endoleak following endovascular aneurysm repair, even after adjustment for patient background. Preoperative assessment and embolization of inferior mesenteric artery might be an important factor for improvement in late EVAR outcomes.

ANZ J Surg 2024; 94:819-825. [PMID: 38131414 DOI: 10.1111/ans.18815] [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: 04/13/2023] [Revised: 11/20/2023] [Accepted: 11/26/2023] [Indexed: 12/23/2023]
Abstract
BACKGROUND Current guidelines for AAA management are based on landmark trials comparing EVAR and open aneurysm repair (OAR) conducted more than 20 years ago. Important advancements have been made in peri-operative care but the impact of EVAR and OAR on long-term patient survival has not been well reported using contemporary data. The objective of this study was to compare the short and long-term outcomes of OAR and EVAR in the recent era. METHODS This retrospective observational study included all patients undergoing intact AAA repair in NZ from 1st of January 2011 until 31st of December 2019. Data was collected from national administrative and clinical vascular databases and matched using unique identifiers. Time-to-event survival analyses was conducted using cox proportional hazard models to adjust for confounders and propensity score matching were used. RESULTS Two thousand two hundred and ninety-seven patients had an intact AAA repair with a median (IQR) age of 75 (69-80) years; 494 (21.2%) patients were females and 1206 (53%) underwent EVAR. The 30-day mortality for OAR and EVAR was 4.8% and 1.2%. The median (IQR) follow up was 5.2 (2.3-9.2) years. After propensity matching for co-variates, the study cohort consisted of 835 patients in each matched group. Patients undergoing EVAR had a higher overall mortality (HR 1.48 (95% CI: 1.26-1.74) after adjusting for confounders compared to OAR. CONCLUSION Analysis of survival following EVAR and OAR in the current era demonstrates that patients that underwent EVAR had a lower 30-day mortality. However, in the long-term after adjusting for confounders OAR had a better overall survival.

Abstract
BACKGROUND The historical size threshold for abdominal aortic aneurysm (AAA) repair is widely accepted to be 5.5 cm for men and 5.0 cm for women. However, contemporary AAA rupture risks may be lower than historical benchmarks, which has implications for when AAAs should be repaired. Our objective was to use contemporary AAA rupture rates to inform optimal size thresholds for AAA repair. METHODS We used a Markov chain analysis to estimate life expectancy for patients with AAA. The primary outcome was AAA-related mortality. We estimated survival using Social Security Administration life tables and published contemporary AAA rupture estimates. For those undergoing repair, we modified survival estimates using data from the Vascular Quality Initiative and Medicare on complications, late rupture, and open conversion. We used this model to estimate the AAA repair size threshold that minimizes AAA-related mortality for 60-year-old average-health men and women. We performed a sensitivity analysis of poor-health patients and 70- and 80-year-old base cases. RESULTS The annual risk of all-cause mortality under surveillance for a 60-year-old woman presenting with a 5.0 cm AAA using repair thresholds of 5.5 cm, 6.0 cm, 6.5 cm, and 7.0 cm was 1.7%, 2.3%, 2.7%, and 2.8%, respectively. The corresponding risk for a man was 2.3%, 2.9%, 3.3%, and 3.4% for the same repair thresholds, respectively. For a 60-year-old average-health woman, an AAA repair size of 6.1 cm was the optimal threshold to minimize AAA-related mortality. Life expectancy varied by <2 months for repair at sizes from 5.7 cm to 7.1 cm. For a 60-year-old average-health man, an AAA repair size of 6.9 cm was the optimal threshold to minimize AAA-related mortality. Life expectancy varied by <2 months for repair at sizes from 6.0 cm to 7.4 cm. Women in poor health, at various age strata, had optimal AAA repair size thresholds that were >6.5 cm, whereas men in poor health, at all ages, had optimal repair size thresholds that were >8.0 cm. CONCLUSIONS The optimal threshold for AAA repair is more nuanced than a discrete size. Specifically, there appears to be a range of AAA sizes for which repair is reasonable to minmized AAA-related mortality. Notably, they all are greater than current guideline recommendations. These findings would suggest that contemporary AAA size thresholds for repair should be reconsidered.

Systematic review of risk factors and outcomes of post-implantation syndrome following endovascular aortic repair. J Vasc Surg 2024; 79:1240-1250.e4. [PMID: 38122858 DOI: 10.1016/j.jvs.2023.12.029] [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: 10/16/2023] [Revised: 12/08/2023] [Accepted: 12/14/2023] [Indexed: 12/23/2023]
Abstract
OBJECTIVE Post implantation syndrome (PIS) is an early systemic inflammatory response following endovascular aortic repair (EVAR). The response is variable in patients and the clinical significance of PIS upon outcomes is unknown. This study aims to evaluate the incidence, risk factors, and prognostic implication of PIS. METHODS Systematic literature review and analysis was performed in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) and Cochrane guidelines of PubMed, Scopus, ClinicalTrials.gov, and the Cochrane Central Register of Controlled Trials. Eligible English-language studies regarding PIS after infrarenal EVAR were included, after removing duplicates. RESULTS After screening, 31 studies were included. A total of 2847 patients were reviewed, with mean age of 70.7 years, of which 2012 (90.4%) were male, with a pooled mean follow-up of 26.1 months. PIS was reported in 25.3% of cases, with mean aneurysm diameter of 56.4 cm. Polytetrafluoroethylene (PTFE) grafts were utilized in 794 patients (27.9%) with polyester in 1839 (64.6%). White blood cell count, C-reactive protein, interleukin (IL)-6, IL-8, and IL-10 levels were all significantly elevated postoperatively. Thirty-day outcomes included type I endoleak rate of 0.8%, type II endoleak rate of 1.7%, reintervention rate of 0.35%, and mortality rate of 0.25%. Subgroup pooled analysis of patients with PIS (n = 309) vs No-PIS (n = 691) revealed that polyester (n = 642), rather than PTFE (n = 234) grafts, were associated with a higher rate of PIS (94.8% vs 3.7%; P = .0001), White blood cell count was higher in the PIS group both preoperatively (7.61 vs 6.76 × 109/L; P = .04) and postoperatively (15.0 vs 9.8 × 109/L; P = .0007) and IL-6 levels were higher in the PIS group postoperatively (98.6 vs 25.2 pg/mL; P = .02). Aneurysm diameter and amount of chronic or new thrombus within the aneurysm sac was not identified as a risk factor for PIS. Pooled outcomes of patients with PIS vs No-PIS demonstrated a significantly higher rate of 30-day mortality (0.6% vs 0%; P = .03) and major adverse cardiac events (5.8% vs 0.43%; P < .0001) without any differences seen in reintervention or 30-day type I or type II endoleaks. CONCLUSIONS This systematic review suggests that polyester grafts are strongly associated with PIS compared with PTFE. Interestingly, this report is suggestive of an association between 30-day mortality and major adverse cardiac events and PIS. Given these clinical sequelae, consideration for use of PTFE over polyester grafts to reduce the incidence of PIS may be a simple step to improve overall outcome. Further, exploration of the relationship between inflammatory mediators associated with PIS and mortality and cardiac complications may engender deeper understanding of risks, leading to eventual mitigation of harm for patients experiencing PIS.

Rakemaa L, Aho PS, Tulamo R, Laine MT, Laukontaus SJ, Hakovirta H, Venermo M. Ultrasound Surveillance is Feasible After Endovascular Aneurysm Repair. Ann Vasc Surg 2024; 100:223-232. [PMID: 37926137 DOI: 10.1016/j.avsg.2023.09.085] [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: 07/06/2023] [Revised: 09/05/2023] [Accepted: 09/09/2023] [Indexed: 11/07/2023]
Abstract
BACKGROUND Surveillance after endovascular aneurysm repair (EVAR) is traditionally done with computed tomography angiography (CTA) scans that exposes patient to radiation, nephrotoxic contrast media, and potentially increased risk for cancer. Ultrasound (US) is less labor intensive and expensive and might thus provide a good alternative for CTA surveillance. The aim of this study was to evaluate in real-life patient cohorts whether US is able to detect post-EVAR aneurysm-related complications similarly to CTA. METHODS This retrospective study compared the outcome of consecutive patients who underwent EVAR for intact abdominal aortic aneurysm and were surveilled solely by CTA (CTA-only cohort, n = 168) in 2000-2010 or by combined CTA and US (CTA/US cohort, n = 300) in 2011-2016, as a standard surveillance protocol in the department of vascular surgery, Helsinki University Hospital. The CTA-only patients were imaged at 1, 3, and 12 months and annually thereafter. The CTA/US patients were imaged with CTA at 3 and 12 months, US at 6 months and annually thereafter. If there were suspicion of >5 mm aneurysm growth, CTA scan was performed. The patients were reviewed for imaging data, reinterventions, aneurysm ruptures, and death until December 2018. The 2 groups were compared for secondary rupture, aneurysm-related and cancer-related death, reintervention related to abdominal aortic aneurysm, and maximum aneurysm diameter increase ≥5 mm. The mean follow-up in the CTA-only cohort was 67 months and in CTA/US cohort 43 months. RESULTS The 2 cohorts were alike for basic characteristics and for the mean aneurysm diameter. The total number of CT scans for detecting aneurysm was 84.1/100 patient years in the CTA-only cohort compared to 74.5/100 patient years for US/CTA cohort. Forty percent of patients under combined CTA/US surveillance received 1 or more additional CTA scans. The 2 cohorts did not differ for 1-year, 5-year and 8-year freedom from aneurysm related death, secondary sac rupture, nor the incidence of rupture preventing interventions. CONCLUSIONS Based on the follow-up data of this real-life cohort of 468 patients, combined surveillance with US and additional CTA either per protocol or due to suspicion of aneurysm-related complications had comparable outcome with sole CTA-surveillance. Thus, US can be considered a reasonable alternative for the CTA. However, our study showed also that the need of additional CTAs due to suspicion of endoleak or aneurysm nonrelated reasons is substantial.

Anthony L, Gillies M, Goh D. Trends in AAA Repair in Australia Over Twenty Years. Vasc Health Risk Manag 2024; 20:69-75. [PMID: 38435054 PMCID: PMC10909325 DOI: 10.2147/vhrm.s449375] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2023] [Accepted: 01/31/2024] [Indexed: 03/05/2024] Open
Abstract
Background The advent of endovascular techniques has revolutionised the treatment of abdominal aortic aneurysms (AAA). Many countries have seen a transition from open AAA repair (OAR) to endovascular AAA repair (EVAR) over the past 25 years. The only study done in Australia that describes this change was done in the private sector. Majority of healthcare in Australia is delivered through the public, universal healthcare system. The aim of this study was to evaluate the trends in AAA repair in the Australian public sector over the past two decades. Methods The Australian Institute of Health and Welfare (AIHW) Procedures Data Cubes from the National Hospitals Data Collection was used to extract data pertaining to AAA repairs from 2000 to 2021. Population data from the Australian Bureau of Statistics was used to calculate incidence of each type of repair per 100,000 population. Results There were 65,529 AAA repairs performed in the Australian public sector from 2000 to 2021. EVARs accounted for 64.4% (42,205) and OARs accounted for 35.6% (23, 324) of them. EVAR surpassed OAR as the preferred method of AAA repair in 2006. This trend was observed in both males and females and across all age groups. Conclusion There was a consistent and steady transition from OAR to EVAR over the 21 year period with EVAR surpassing OAR as the preferred method of AAA repair relatively early in Australia compared to other countries. Further research that investigates medium- and long-term outcomes of newer stent grafts is needed to further ascertain the continued viability and effectiveness of this trend in AAA treatment.

Abstract
BACKGROUND Limb occlusion is a potentially serious consequence of endovascular abdominal aortic aneurysm (EVAR). This case-control study identifies factors that predispose to limb occlusion. METHODS A consecutive series of patients from 2 centers undergoing EVAR over an 11-year period 2007-2017 were identified retrospectively. Patient records were interrogated allowing collations of demographics, intraoperative and perioperative data and surveillance data. The preoperative computed tomography angiogram was analyzed to determine EVAR relevant anatomical data. The primary outcome was occlusion of the iliac limb of the implanted EVAR. Raw data are presented as percentages, with comparative data analyzed using Mann-Whitney U-test and binomial logistic regression. RESULTS A total of 787 patients (702 males; median age 78 years, range 53-94 years old) were analyzed. Fifty patients reached the primary outcome, resulting in an overall limb occlusion rate of 6.35%. Factors predictive of limb occlusion were oversizing by >10% native vessel diameter, with oversizing of >20% in 50% of those that occluded. External iliac artery landing zone (12/50 limb occlusions) 24% and postoperative kinking (5/50 limb occlusions) 10% were also more common in those that occluded. Fifty randomly selected controls with similar baseline characteristics were studied. Oversizing of the iliac endograft was found to be significantly greater in the limb occlusion group compared to the controls (P < 0.001) which remained significant on regression analysis. There was no correlation with iliac tortuosity. The Cook stent graft had a 9% limb occlusion rate across sites. Medtronic and Vascutek endografts had 2.4% and 2.5% limb occlusion rates respectively. CONCLUSIONS Oversizing of iliac limbs by >20% could be a contributing factor to limb occlusion after EVAR and judicious oversizing should be used.

Abstract
OBJECTIVE The European Society for Vascular Surgery (ESVS) has developed clinical practice guidelines for the care of patients with aneurysms of the abdominal aorta and iliac arteries in succession to the 2011 and 2019 versions, with the aim of assisting physicians and patients in selecting the best management strategy. METHODS The guideline is based on scientific evidence completed with expert opinion on the matter. By summarising and evaluating the best available evidence, recommendations for the evaluation and treatment of patients have been formulated. The recommendations are graded according to a modified European Society of Cardiology grading system, where the strength (class) of each recommendation is graded from I to III and the letters A to C mark the level of evidence. RESULTS A total of 160 recommendations have been issued on the following topics: Service standards, including surgical volume and training; Epidemiology, diagnosis, and screening; Management of patients with small abdominal aortic aneurysm (AAA), including surveillance, cardiovascular risk reduction, and indication for repair; Elective AAA repair, including operative risk assessment, open and endovascular repair, and early complications; Ruptured and symptomatic AAA, including peri-operative management, such as permissive hypotension and use of aortic occlusion balloon, open and endovascular repair, and early complications, such as abdominal compartment syndrome and colonic ischaemia; Long term outcome and follow up after AAA repair, including graft infection, endoleaks and follow up routines; Management of complex AAA, including open and endovascular repair; Management of iliac artery aneurysm, including indication for repair and open and endovascular repair; and Miscellaneous aortic problems, including mycotic, inflammatory, and saccular aortic aneurysm. In addition, Shared decision making is being addressed, with supporting information for patients, and Unresolved issues are discussed. CONCLUSION The ESVS Clinical Practice Guidelines provide the most comprehensive, up to date, and unbiased advice to clinicians and patients on the management of abdominal aorto-iliac artery aneurysms.

Abstract
BACKGROUND While endovascular aneurysm repair has become a first-line strategy in many centers, open surgical repair (OSR) of abdominal aortic aneurysms (AAAs) is still the best option for certain patients. A significant number of patients who are offered OSR for AAA have been previously submitted to other open abdominal surgeries (PAS). It is unclear, however, how this may impact their outcomes. The purpose of this study was to determine if there is an association between PAS and outcomes of OSR of AAA. METHODS This is a retrospective cohort study based on clinical data from the American College of Surgeons National Surgical Quality Improvement Program database, including all patients undergoing elective OSR for AAA between 2011 and 2017. Excluded were patients with missing data on prior abdominal surgery, supramesenteric clamping, or urgent repairs. Patients with prior abdominal surgery (PAS) and patients without prior abdominal surgeries (nonPAS) were compared. The primary outcome was 30-day postoperative mortality. Secondary outcomes were operating time, ischemic colitis, postoperative complications, and lengths of hospital stay. RESULTS Of the 2034 patients included, 27% had previous open abdominal surgery and 73% did not. Overall, the median age was 71(interquartile range 65-76), 72% of patients were male, 44% were smokers, and the average body mass index was 27 kg/m2. Univariate analysis showed no difference in postoperative 30-day mortality (4.0% PAS vs. 4.1% nonPAS, P = 0.91) or overall postoperative complication rates (33% PAS vs. 29% nonPAS, P = 0.07). Previous open abdominal surgery was significantly associated with longer operating times (P = 0.032) and an almost doubled rate of ischemic colitis (4.7% PAS vs. 2.6% nonPAS, P = 0.02). Postoperative intensive care unit and hospitalization were also significantly longer in patients with prior abdominal surgery (P = 0.005 and P = 0.014, respectively). Finally, there were significantly less patients discharged home, as opposed to institutionalized care (75.7% PAS down from 82.4% nonPAS, P = 0.001). Despite these initial univariate analysis results, on multivariate analysis, PAS actually did not prove to be a statistically significant independent risk factor for 30-day mortality, ischemic colitis, or longer operating times. CONCLUSIONS This study suggests that patients who have undergone PAS may have some disadvantages in OSR of AAA. However, these negative trends do not go so far as to statistically significantly identify PAS as an independent risk factor for 30-day mortality, ischemic colitis, or longer operating times. As such, we suggest that a history of previous open abdominal surgery, in and of its own, should not exclude patients from consideration for open aortic abdominal aneurysm repair.

Abstract
Objective Endovascular aortic repair (EVAR) has become a routine procedure worldwide. Ultimately, the increasing number of EVAR cases entails changing conditions for open surgical repair (OSR) regarding patient selection, complexity, and surgical volume. This study aimed to assess the time trends of open abdominal aortic aneurysm (AAA) repair in a high-volume single center in Austria over a period of 20 years, focusing on the operation time and clinical outcomes. Materials and methods A retrospective analysis of all patients treated for infrarenal AAAs with OSR or EVAR between January 2000 and December 2019 was performed. Infrarenal AAA was defined as the presence of a >10-mm aortic neck. Cases with ruptured or juxtarenal AAAs were excluded from the analysis. Two cohorts of patients treated with OSR at different time periods, namely, 2000-2009 and 2010-2019, were assessed regarding demographical and procedure details and clinical outcomes. The time periods were defined based on the increasing single-center trend toward the EVAR approach from 2010 onward. Results A total of 743 OSR and 766 EVAR procedures were performed. Of OSR cases, 589 were infrarenal AAAs. Over time, the EVAR to OSR ratio was stable at around 50:50 (p = 0.488). After 2010, history of coronary arterial bypass (13.4% vs. 7.2%, p = 0.027), coronary artery disease (38.1% vs. 25.1%, p = 0.004), peripheral vascular disease (35.1% vs. 21.3%, p = 0.001), and smoking (61.6% vs. 34.3%, p < 0.001) decreased significantly. Age decreased from 68 to 66 years (p = 0.023). The operation time for OSR remained stable (215 vs. 225 min, first vs. second time period, respectively, p = 0.354). The intraoperative (5.8% vs. 7.2%, p = 0.502) and postoperative (18.3% vs. 20.8%, p = 0.479) complication rates also remained stable. The 30-day mortality rate did not change over both time periods (3.0% vs. 2.4%, p = 0.666). Conclusion Balanced EVAR to OSR ratio, similar complexity of cases, and volume over the two decades in OSR showed stable OSR time without compromise in clinical outcomes.

Abstract
BACKGROUND The advent of endovascular techniques has revolutionized the care of patients with uncomplicated abdominal aortic aneurysms. This analysis compares the overall survival and the freedom from reintervention rate between open surgical repair (OSR) and endovascular repair (EVAR) in patients undergoing elective abdominal aortic aneurysm (AAA) repair. METHODS PubMed, Scopus, and Cochrane databases were searched for studies including patients who underwent either OSR or EVAR for uncomplicated AAA. All randomized controlled trials and propensity-score-matched cohort studies reporting on the outcomes of interest were considered eligible for inclusion. The systematic search of the literature was performed by 2 independent investigators in accordance with the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. We conducted 1-stage and 2-stage meta-analyses with Kaplan-Meier-derived time-to-event data and meta-analysis with a random-effects model. RESULTS Thirteen studies met our eligibility criteria, incorporating 13 409 and 13 450 patients in the OSR and EVAR arms, respectively. Patients who underwent open repair had improved overall survival rates compared with those who underwent EVAR (hazard ratio [HR]=0.93, 95% confidence interval [CI]=0.88-0.98, p=0.004) during a mean follow-up of 53.8 (SD=29.8) months and this was validated by the 2-stage meta-analysis (HR=0.89, 95% CI=0.8-0.99, p=0.03, I2=62.25%). Splitting timepoint analysis suggested that EVAR offers better survival outcome compared with OSR in the first 11 months following elective intervention (HR=1.37, 95% CI=1.22-1.54, p<0.0001), while OSR offers a significant survival advantage after the 11-month timepoint and up to 180 months (HR=0.84, 95% CI=0.8-0.89, p<0.0001). Similarly, freedom from reintervention was found to be significantly better in EVAR patients (HR=1.28, 95% CI=1.14-1.44, p<0.0001) within the first 30 days. After the first month postrepair, however, OSR demonstrated higher freedom-from-reintervention rates compared with EVAR that remained significant for up to 168 months during follow-up (HR=0.73, 95% CI=0.66-0.79, p<0.0001). CONCLUSIONS Despite the first-year survival advantage of EVAR in patients undergoing elective AAA repair, OSR was associated with a late survival benefit and decreased risk for reintervention in long-term follow-up. CLINICAL IMPACT Open surgical repair for uncomplicated abdominal aortic aneurysm offers better long-term outcomes in terms of survival and freedom from reintervention rate compared to the endovascular approach but in the first year it carries a higher risk of mortality. The novelty of our study lies that instead of comparing study-level effect estimates, we analyzed reconstructed individual patient-level data. This offered us the opportunity to perform our analyses with mathematically robust and flexible survival models, which was proved to be crucial since there was evidence of different hazard over time. Our findings underline the need for additional investigation to clarify the significance of open surgical repair when compared to the latest endovascular devices and techniques within the evolving era of minimally invasive procedures.

[PMID: 37330200 DOI: 10.1016/j.ejvs.2023.06.003] [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: 09/20/2022] [Revised: 04/10/2023] [Accepted: 06/05/2023] [Indexed: 06/19/2023]
Abstract
OBJECTIVE This study aimed to investigate the impact of the number of patent lumbar arteries (LAs) on sac enlargement after endovascular aneurysm repair (EVAR). METHODS This was a retrospective cohort single centre registry study. Between January 2006 and December 2019, 336 EVARs were reviewed using a commercially available device excluding type I or type III endoleaks during a follow up of ≥ 12 months. Patients were divided into four groups based on the pre-operative patency of the inferior mesenteric artery (IMA) and high (≥ 4) or low (≤ 3) number of patent LAs: Group 1, patent IMA and high number of patent LAs; Group 2, patent IMA and low number of patent LAs; Group 3, occluded IMA and a high number of patent LAs; Group 4, occluded IMA and low number of patent LAs. RESULTS Groups 1, 2, 3, and 4 included 124, 104, 45, and 63 patients, respectively. The median follow up duration was 65.1 months. Significant differences in the incidence of overall type II endoleak (T2EL) at discharge between Group 1 and Group 2 (59.7% vs. 36.5%, p < .001) and between Group 3 and Group 4 (33.3% vs. 4.8%, p < .001) were observed. In patients with a pre-operatively patent IMA, the rate of freedom from aneurysm sac enlargement was significantly lower in Group 1 than in Group 2 (69.0% vs. 81.7% five years after EVAR, p < .001). In patients with a pre-operatively occluded IMA, the freedom rate from aneurysm sac enlargement was not significantly different between Groups 3 and Group 4 (95.0% vs. 100% five years after EVAR, p = .075). CONCLUSION A high number of patent LAs seemed to have a significant role in sac enlargement with T2EL when the IMA was patent pre-operatively, whereas a high number of patent LAs seemed to have limited influence on sac enlargement when the IMA was occluded pre-operatively.

Abstract
BACKGROUND Endovascular abdominal aortic repair (EVAR) is the main therapeutic option for repairing abdominal aortic aneurysms (AAAs). We aimed to determine the long-term outcomes of patients who underwent EVAR at our center. METHODS In this retrospective cohort study, patients who underwent EVAR for intact isolated AAA at Tehran Heart Center between 2007 and 2017 were included. Clinical outcomes and the frequency of mortality were analyzed for follow-up periods. We calculated the 5-year survival rate and its predictors for our patients using Kaplan-Meier estimation. RESULTS We included the data of all patients (154 patients, mean age = 70.7 [± 8.0] years, 96.1% men) who successfully underwent EVAR at our center. The most common risk factors were coronary artery disease (70.1%), hypertension (68.2%), smoking (64.9%), and dyslipidemia (39.6%). There was no mortality during the procedure. The median follow-up was 65.5 months. An average decrease of 9.07 mm (95% confidence interval: 6.9-11.2) occurred in the size of the AAA. During follow-up, 12 patients developed some complications, 49 died, and 7 did not complete the follow-up. The 5-year survival rate was 75% (3.9%). The independent predictors for 5-year survival were age (hazard ratio [HR] = 1.06, P = 0.002) and anemia (HR = 1.91, P = 0.029). Despite not being statistically significant, dyslipidemia (HR = 0.573, P = 0.078) and long intensive care unit/cardiac care unit stays (HR = 1.08, P = 0.070) were borderline mortality predictors. CONCLUSIONS This study depicted an acceptable survival rate for patients who underwent EVAR at our center. Age and anemia, 2 modifiable predictors of 5-year survival, can probably prolong the survival rate of patients, which requires evaluation later.

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
INTRODUCTION Since the introduction of endovascular aortic repair (EVAR) it has become the mainstay treatment for abdominal aortic aneurysms. Several EVAR devices exist commercially, yet, the Terumo Aortic Fenestrated Anaconda™ endograft has demonstrated outstanding results. Evidence in the literature suggests that sac regression could be linked to patient survival and longevity. The main scope of this study is to evaluate sac regression and survival achieved using the Fenestrated Anaconda™ endograft and to discuss relevant literature. MATERIALS AND METHODS The current study represents a nine-year cross-sectional international analysis of custom-made Fenestrated Anaconda™ device. For the statistical analysis, SPSS 28 for Windows and R were utilised. Pearson chi-square analysis was used to assess differences in cumulative distribution frequencies between select variables. Statistical significance for all two-tailed tests was set at p < 0.05. RESULTS A total of 5,058 patients received the Fenestrated Anaconda™ in this study, either due to unsuitable/complex anatomy for competitor devices (n = 3,891) or based on surgeon preference (n = 1,167). A sac regression of 0-30% was observed in 4,772 (94.3%) over the first four years post-EVAR. Here, 99.6% of patients receiving the Fenestrated Anaconda™ due to unsuitable/complex anatomy for competitor devices and 76.8% based on surgeon preference had 0-30% sac regression. During years 5-9 of follow-up, all patients had 20-45% sac regression. Patient survival during the first six years post-EVAR was 100% but dropped to 77.1% in years 7-9. Survival differed between categorical patient subsets based on the indication. DISCUSSION The Fenestrated Anaconda™ has been proven to be a highly effective EVAR endograft. Evidence in the literature clearly demonstrates that sac regression is an accurate prognostic factor for patient survival and longevity.

Abstract
BACKGROUND The introduction of endovascular aortic repair has revolutionised the treatment of abdominal aortic aneurysms, replacing open surgical repair for the majority of elective cases due to its optimal morbidity and mortality. Several endovascular aortic repair stent grafts exist commercially, one of which is the Fenestrated Anaconda™ by Terumo Aortic which benefits from a very innovative design, unique custom-made approach and highly favourable results. AIMS The main scope of this narrative review is to provide a comprehensive overview of endovascular aortic repair clinical outcomes using the Fenestrated Anaconda™ stent-graft and comparing these with its market competitor, Zenith. This review will also examine the evidence in the literature on the Anaconda™'s custom-made approach. METHODS A comprehensive literature was conducted on several search engines including PubMed, Google Scholar, Ovid, Scopus and Embase to collate the evidence in the literature on clinical outcomes achieved with the Fenestrated Anaconda™ and Zenith including, but not limited to, survival, technical success, target vessel patency, endoleak, reintervention and aneurysm sac regression. RESULTS The Fenestrated Anaconda™ is associated with excellent results, including highly favourable survival, technical and clinical success and target vessel patency rates, very low need for reintervention or conversion, and minimal incidence of complications such as endoleak and endograft migration. The Fenestrated Anaconda™ also drives significant sac regression and aortic remodelling. In addition, its unique custom-made approach enables it to treat highly complex aortic anatomy as well as to 'rescue' failed competitor grafts. CONCLUSION The Fenestrated Anaconda™ has proven that it is a very safe, highly applicable and extremely effective device used for complex aortic and/or iliac pathology based on its novel design and outstanding track record of clinical outcomes.

Abstract
OBJECTIVE The presence of endoleak was associated with the failure of endovascular aortic aneurysm repair (EVAR) treatment. The key to eliminating type II endoleak has shifted from reintervention to prevention. This study aimed to evaluate the effectiveness and safety of applying fibrin sealant to prevent type II endoleak in conjunction with EVAR. METHODS All patients with abdominal aortic aneurysm who underwent EVAR from June 2019 to July 2021 were reviewed. Patients were grouped as Group A: standard EVAR with preemptive embolization and Group B: standard EVAR alone. The primary endpoint was the incidence of type II endoleak. The secondary endpoints were aneurysm sac regression, the inferior mesenteric artery patency, the numbers of patent lumbar arteries, and all-cause mortality. RESULTS A total of 104 patients were included in Group A, and 116 were included in Group B. Technical success rate was 100%. The overall incidence of type II endoleak in Group A was significantly lower than that in Group B (4.8% vs 19.0%). The mean time of freedom from type II endoleak was 22.71 months for Group A (95% confidence interval, 21.59-23.83 months) and 19.89 months for Group B (95% confidence interval, 18.08-21.70 months). The Kaplan-Meier estimate of freedom from type II endoleak showed a significantly longer duration of freedom from type II endoleak in Group A (81.0% vs 95.2%). Group A showed a continuous sac regression tendency. In Group B, the sac volume decreased within 12 months but increased by 3.07 cm3 at 24 months. No complications were noted in both groups. CONCLUSIONS Nonselective preemptive embolization with porcine fibrin sealant during EVAR was safe and effective in preventing type II endoleak in the short and mid-term. Preemptive embolization can lead to a significantly higher sac regression rate. Larger patient populations and longer follow-ups with randomized control designed trials are expected to verify the long-term effectiveness and safety of preemptive embolization in preventing type II endoleak.

Abstract
BACKGROUND Endovascular aortic aneurysm repair (EVAR) has become the most common procedure for treating abdominal aortic aneurysms based on multiple studies conducted in the western world. The implication of such findings in developing countries is not well demonstrated. The objective of this study was to compare medical outcomes and costs of EVAR and open surgical repair (OSR) in a developing country. METHODS This is a retrospective study of all patients undergoing elective abdominal aortic aneurysm repair between 2005 and 2020 at a tertiary medical center in a developing country. Medical records were used to retrieve demographics, comorbidities, and perioperative complications. Medical records were also used to provide data on the need of reintervention, date of last follow-up, and mortality. RESULTS The study included a total of 164 patients. Median follow-up time was 41 months. The mean age was 69.9 +/- 7.84 years and 90.24% (n = 148) of patients were males. Regarding long-term mortality outcomes, no significant difference was detected between both groups; OSR patients had a survival rate of 91.38% and 74.86% at 5 and 10 years, compared to 77.29% and 56.52% in the EVAR group (P value = 0.10). Both groups had comparable long-term reintervention rates (P value = 0.334). The OSR group was charged significantly less than the EVAR group ($27,666.35 vs. $44,528.04, P value = 0.008). CONCLUSIONS OSR and EVAR have comparable survival and reintervention outcomes. Unlike what was reported in developed countries, patients undergoing OSR in countries with low hospital stay costs incur lower treatment costs.

Abstract
Abdominal aortic aneurysm (AAA) is a degenerative disease of the aortic wall with potentially fatal complications. The widespread adoption of endovascular aneurysm repair (EVAR), which is less invasive and equally (if not more) effective for abdominal aortic aneurysms (AAA), is due to the obvious advantages of the procedure compared to the traditional open repair. As the popularity of endovascular procedures grows, related complications become more evident, with kidney damage being one of them. Although acute kidney injury following EVAR is relatively common, its true incidence is still uncertain. The purpose of this study was to assess the incidence of acute kidney injury among patients treated with endovascular repair of ruptured AAA. In addition, we aimed to determine the predictors of PC-AKI in patients with abdominal aortic aneurysm treated with EVAR. PATIENTS AND METHODS We retrospectively analyzed a prospective registry of abdominal aortic aneurysm of 247 patients operated endovascularly at a single center between 2015 and 2021. Due to a lack of clinical data, data of 192 patients were reviewed for postcontrast acute kidney injury. Additional comorbidities were included in this study: hypertension, diabetes mellitus, atrial fibrillation, chronic coronary syndrome, COPD, and chronic kidney disease. Follow-up examinations were performed before the procedure and 48 h after contrast administration. RESULTS The group of 36 patients developed PC-AKI, which is 19% of the entire study population. Hypertension, diabetes, chronic kidney disease, male gender, and incidence of PC-AKI were more prevalent in patients with higher aortic aneurysm diameter ≥67 mm. In multiple regression analyses, independent predictors of PC-AKI were serum creatinine, chronic kidney disease, male gender, and aortic aneurysm diameter ≥67 mm. CONCLUSIONS One of the major complications after EVAR is acute kidney injury, which is linked to higher death and morbidity rates. Independent risk factors for postcontrast acute kidney injury were chronic kidney disease, male gender, and aortic diameter. Only aortic diameter could be modifiable risk factor, and earlier surgery could be considered to yield better outcomes. More research is critically needed to determine how AKI affects long-term outcomes and to look at preventive options.

Li Y, He C, Zhang H, Zhang X, Zhang X, Zhang T. Endovascular Repair for Abdominal Aortic Aneurysm in Mainland China: A Systematic Review and Meta-Analysis. Ann Vasc Surg 2023; 89:338-352. [PMID: 36343863 DOI: 10.1016/j.avsg.2022.09.058] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2022] [Revised: 08/31/2022] [Accepted: 09/24/2022] [Indexed: 11/06/2022]
Abstract
BACKGROUND The aim of this study was to evaluate the safety, applicability, and outcomes of the endovascular aneurysm repair (EVAR) technique for patients in mainland China with abdominal aortic aneurysm (AAA) by performing a systematic review. METHODS We conducted a systematic search using the PubMed, Embase, Chinese National Knowledge Infrastructure, and Chinese Biomedical databases to identify Chinese studies on the management of AAAs using the EVAR technique published in English between January 2000 and December 2020. Two independent observers selected studies for inclusion in the study, assessed the methodological quality of the included studies, and extracted the data. The included studies investigated the clinical outcomes and postprocedural complications of using EVAR techniques. RESULTS Sixteen studies reported a total of 3,024 AAA patients. The follow-up period ranged from 1 to 133 months. The mean follow-up time was 38.5 months, the mean age was 69.2 years, and the mean aneurysm diameter was 56.1 mm. The pooled technical success rate was 95% (95% confidence interval [CI]: 92-96%). The endoleak rate was 7% (95% CI: 6-8%). The rate of endoleak requiring reintervention was 3% (95% CI: 3-4%). The 30-day morbidity rate was 9% (95% CI: 6-14%). The 30-day mortality rate was 2% (95% CI: 1-3%). The follow-up mortality was 5% (95% CI: 3-8%). CONCLUSIONS The results of the study showed that using the EVAR technique for treating patients in mainland China with AAAs produced encouraging mid-term outcomes. Long-term outcomes should be examined in future research.

A nomogram risk assessment model to predict the possibility of type II endoleak-related re-intervention after endovascular aneurysm repair (EVAR). Sci Rep 2023; 13:14. [PMID: 36593362 PMCID: PMC9807575 DOI: 10.1038/s41598-022-27356-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2022] [Accepted: 12/30/2022] [Indexed: 01/04/2023] Open
Abstract
This study aimed to develop and validate a novel nomogram risk assessment model to predict the possibility of type II endoleak (T2EL)-related re-intervention. The data of 455 patients with abdominal aortic aneurysms who underwent elective endovascular aneurysm repair (EVAR) procedures between January 2018 and December 2021 at our single center were retrospectively reviewed. Following the implementation of exclusion criteria, 283 patients were finally included and divided into T2EL-related re-intervention (n = 42) and non-T2EL (n = 241) groups. The overall T2EL-related re-intervention rate for 283 patients was 14.8% (42/283). Using multivariate analysis, significant risk factors for re-intervention included age (OR, 1.172; 95% CI, 1.051-1.307; P = 0.004), smoking (OR, 13.418; 95% CI, 2.362-76.215; P = 0.003), diameter of inferior mesenteric artery (IMA) (OR, 21.380; 95% CI, 3.060-149.390; P = 0.002), and number of patent lumbar arteries (OR, 9.736; 95% CI, 3.175-29.857; P < 0.001). The discrimination ability of this risk-predictive model was reasonable (concordance index [C-index] = 0.921; 95% CI, 0.878-0.964). The Hosmer-Lemeshow goodness of fit test was performed on the model, and the chi-square value was 3.210 (P = 0.920), presenting an excellent agreement between the model-predicted and observed values. The receiver operating characteristic (ROC) curve identified that the risk thresholds of re-intervention were a diameter of > 2.77 mm for the diameter of the inferior mesenteric artery and a proportion of < 45.5% for thrombus volume in the aneurysm sac. This novel nomogram risk assessment model for predicting the possibility of patients' T2EL-related re-interventions after EVAR should be helpful in discriminating high-risk patients. Two novel risk thresholds may imply a higher possibility of T2EL-related re-intervention after EVAR.

Abstract
BackgroundEndovascular aneurysm repair (EVAR) is often seen as the first choice treatment for patients with abdominal aortic aneurysm (AAA), particularly high-risk patients, yet the long-term survival rate and improvement in quality of life are still unclear. In order to seek the value of EVAR to the entire healthcare field, we conducted a retrospective study to evaluate whether the improvement EVAR can truly bring to the quality of medical care in the era of value-based healthcare.MethodsWe included AAA patients who underwent surgical treatment in the Department of Vascular Surgery, First Hospital of China Medical University, from January 1, 2004, to December 31, 2019 and evaluated surgery procedure data, short-term and long-term mortality, complications, prognoses, and medical costs.ResultsWe analyzed 507 patients with AAA who underwent open repair (n = 232) or EVAR (n = 275) over a 15-year period. The operative time, blood loss, blood transfusion rate, and postoperative length of hospital stay of the EVAR group is significantly lower than which of the open repair group. Meanwhile, neither short-term nor long-term mortality rates shows significant differences between the two groups. On the other hand, the complication rate of the EVAR group was significantly higher than that of the open repair group. Lastly, the total cost of EVAR was significantly higher than that of open repair.ConclusionExisting evidence suggests that EVAR improves neither short-term nor long-term survival rate compared with open surgery. In contrast, the complication rate and the reintervention rate in the EVAR group were higher than those in the open surgery group. Moreover, the cost of EVAR and that paid by medical insurance were higher than those for open surgery. For patients with a long-life expectancy, in order to ensure that patients receive appropriate and effective care, surgeons should choose a suitable method that considers both the quality of medical care as well as the expense accordingly.

The Effect of Smoking Status on Perioperative Morbidity and Mortality after Open and Endovascular Abdominal Aortic Aneurysm Repair. Ann Vasc Surg 2022; 88:373-384. [PMID: 36058453 DOI: 10.1016/j.avsg.2022.07.027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2022] [Revised: 07/15/2022] [Accepted: 07/21/2022] [Indexed: 11/20/2022]
Abstract
OBJECTIVES This study quantifies the extent to which active tobacco smoking is deleterious towards outcomes following open and endovascular AAA repair. METHODS Open and endovascular abdominal aortic aneurysm (AAA) repairs between January 2003 and June 2020 in the Vascular Quality Initiative (VQI) were queried. Rupture, symptomatic status, and lack of 90 day follow up were exclusions. Patients were then placed into one of six groups : open AAA with active smoking (n=3788); open AAA with prior smoking (n=4614); open AAA never smokers (817); endovascular AAA active smokers (n=14173); endovascular AAA former smokers (n=25,831); and, endovascular AAA never smokers (n=6064). Comparison of baseline characteristics, co-morbidities, and adverse outcomes across each of the 6 cohorts was performed with open AAA in active smokers serving as the reference. Sub-analysis investigating open AAA repair in active smokers relative to open AAA in patients confirmed in VQI to have quit smoking between 30 and 90 days before surgery was performed. Smoking cessation for a minimum of 30 days before surgery was required to fall into the former smoker category. RESULTS In comparing open AAA in active smokers to open AAA in former and never smokers, the active smokers experienced significantly higher rates of pneumonia (P<.001). Combined additive morbidity and mortality was highest (54%) in active smokers (P<.001 relative to all cohorts other than open AAA former smokers P=.21). Smoking status did not impact morbidity or mortality incidence across individuals undergoing EVAR. Binary logistic regression for all AAA patients (open and endovascular combined) revealed those with any history of smoking to be more likely to experience 90 day mortality (adjusted OR 2.5 (2.2-2.9), P<.001) relative to never-smokers. Active smokers were similarly more likely to experience 90 day mortality than prior/never smokers combined (OR 1.23 (1.07-1.38), P<.001). Mortality within 90 days was significantly more likely (P<.001) with aging, female gender, larger aneurysms, preoperative history of congestive heart failure, chronic obstructive pulmonary disease, chronic renal insufficiency, peripheral artery disease, body mass index under 20 and over 35 mg/kg2. Diabetes and coronary artery disease were also associated with 90 day mortality (P= .045 and .049 respectively). Quitting smoking between 30 and 90 days before open repair reduced combined additive morbidity and mortality relative to active smokers (OR 1.34, P =.038). CONCLUSIONS Smoking cessation 30 days before open AAA repair reduces perioperative morbidity and mortality. Smoking status does not impact morbidity and mortality in patients undergoing endovascular AAA repair. When combining all patients (open and endovascular), higher rates of 90 day mortality are associated with any history of smoking, aging, female gender and advanced pre-existing co-morbidities on multivariable analysis.

Abstract
INTRODUCTION Clinical trials at the advent of endovascular aortic aneurysm repairs (EVARs) demonstrated improved early survival with EVAR compared to open repairs; however, characterizations of routine contemporary care have been limited. This study compares postoperative survival among Veterans in clinical care following abdominal aortic aneurysm (AAA) repair with EVAR versus open repairs since the widespread adoption of EVAR. MATERIALS AND METHODS This retrospective cohort analysis of Veterans with AAA repairs from 2007 to 2020 at Veterans Affairs (VA) facilities evaluated survival by a repair method. Administrative International Classification of Diseases 9/10 codes and sociodemographic characteristics from structured charting were used for characterization and adjusted analyses. Demographics were compared via Chi-squared and Wilcoxon rank-sum testing and mortality evaluated using Kaplan-Meier and Cox proportional hazard analyses. RESULTS Among 15,480 AAA repairs (3566 open, and 11,914 EVAR), patients receiving open repairs were younger with lower Charlson scores compared to EVARs. EVAR was associated with better survival until 2.4 y post-procedure. Mean long-term survival, however, was higher for open surgery (6.3 ± 3.8 versus 5.8 ± 3.1 y in EVAR). After adjustment for gender, race, and ethnicity, EVAR was associated with worse survival (mortality hazard ratio [HR] 1.17; 95% confidence interval [CI], 1.11-1.24) as was each increment in Charlson score (HR 1.11; CI 1.10-1.12), whereas service-connected care (HR 0.73; CI, 0.70-0.77) and age (HR 0.99; CI, 0.98-0.99) were associated with better survival. CONCLUSIONS In contemporary Veteran aneurysm repairs, although a higher early survival rate was observed in EVAR repairs, long-term survival was higher for open repairs. Service-connected care was independently associated with greater survival after aneurysm repair.

Abstract
Purpose: The purpose of this study was to evaluate tranexamic acid (TA) for the prevention of type II endoleak (EL2) at a high level of evidence by a randomized controlled trial. Methods: Patients who underwent endovascular aneurysm repair (EVAR) between May 2017 and January 2020 were included. Patients in the TA group were given 750 mg of TA daily for a month after EVAR. The incidence of EL2, blood coagulation/fibrinolytic ability, and changes in aneurysm diameter were compared between two groups. Result: On the 7th day after EVAR, EL2 was found in 14 patients (34.1%) in the TA group and in 7 patients (15.9%) in the non-TA group. It was also found in 12 patients (29.3%) in the TA group and 6 patients (13.6%) in the non-TA group at 1 month after EVAR. There was no significant difference in the incidence of EL2 between the two groups (p = 0.051, 0.08). Blood tests revealed that fibrin degradation product and D-dimer were significantly suppressed in the TA group, there was no significant difference in the change of diameter regardless of the TA intake. Conclusion: This study proved anti-fibrinolytic effect of the TA, but it alone had not enough power to decrease EL2 after EVAR.

Single-Center Analysis on The Evolution of Procedural Characteristics Over 15 Years. JOURNAL OF SURGICAL EDUCATION 2022; 79:885-895. [PMID: 35151591 DOI: 10.1016/j.jsurg.2022.01.010] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Revised: 11/22/2021] [Accepted: 01/21/2022] [Indexed: 06/14/2023]
Abstract
OBJECTIVE In many vascular centers an endovascular first policy for the treatment of abdominal aortic aneurysms (AAA) has resulted in endovascular aortic repair (EVAR) outnumbering open aortic repair (OAR). The declining routine in OAR raises the question whether this might influence procedural outcomes and diminish surgical expertise for current and future vascular surgeons. We aimed to analyze OAR outcomes, AAA morphology and procedural details over the past 15 years while an endovascular first approach was successively implemented. PARTICICPANTS AND DESIGN All patients operated for (i)ntact infra-/juxtarenal AAA between January 1, 2005 and December 31, 2019 were identified. Outcome parameters were length of stay (hospital/ICU), in-hospital mortality and medical/surgical complications. Operative details were clamping zone, access and graft configuration. AAA anatomy including neck and iliac parameters was analyzed with Endosize©. Logistic regression, uni- and multivariate analysis were applied. RESULTS 293 patients received elective OAR for iAAA. Baseline characteristics (age, sex, hypertension, smoking, occlusive disease, coronary disease, hyperlipidemia, diabetes, renal insufficiency and obesity) did not change over time. The number of OAR dropped significantly (-0.5 cases/year p = 0.02). The procedure time (2005-2007: 192.2 ± 87.5min to 2017-2019: 235.6 ± 88.2min; p = 0.0001) and the length of stay (2005-2007: 12.0 ± 7.9 to 2017-2019: 17.0 ± 23.1; p = 0.03) increased significantly, whereas the in-hospital mortality, length of ICU stay and complication rates didn't, nor did AAA anatomy. Upon multivariate analysis, annual number of OAR and any additional anastomosis significantly influenced procedure time, trainee involvement, for example, did not. Hospital length-of-stay depended on patient age (p = 0.002), complication rates (p < 0.0001) and procedure time (p = 0.006). CONCLUSION Mortality and complication rates for OAR have remained low and constant. With the increase of EVAR, the absolute number of OARs has decreased significantly. However, the total procedure time has increased and depends significantly on the annual number of OARs in total and per surgeon. This might influence outcome parameters and should be implanted in future surgical education.

Abstract
BACKGROUND Abdominal aortic aneurysms can either be treated by open surgery or endovascular repair. In both cases, prostheses are implanted to prevent potentially lethal aortic ruptures. OBJECTIVES Studies seeking to identify the optimal treatment came to diverging conclusions. The goal of this article is to shed light on the discussion of which treatment option is to be preferred. MATERIALS AND METHODS This article summarizes the relevant studies on elective and emergency abdominal aortic aneurysm repair. The presented studies are discussed, and results are interpreted and compared. RESULTS While most studies indicate lower short-term mortality rates in endovascular aneurysm repair (EVAR), mortality rates converged in multiple trials and even showed a lower mortality rate for open repair in mid-term analyses. Most recent studies indicate long-term equivalence in terms of mortality and a higher rate of secondary interventions in EVAR patients. CONCLUSIONS The current body of literature indicates no real advantage of one therapy over another. The choice of therapy should depend on anatomic, clinical, and logistic criteria.

Abstract
Sämtliche Patienten nach endovaskulärer Versorgung eines Aortenaneurysmas bedürfen einer regelmäßigen Nachkontrolle, zumeist in jährlichem Abstand. Der kontrastmittelverstärkte Ultraschall und die Computertomographie-Angiographie (CTA) sind die wichtigsten diagnostischen Modalitäten für die Erkennung von Endoleaks. Die (CTA) erlaubt eine bessere Unterscheidung der verschiedenen Endoleak-Typen. Sogenannte Hochdruck-Endoleaks (Typ I und Typ III) stellen, wenn sich nicht kurzzeitig ein Spontanverschluss zeigt, eine absolute Indikation zur Nachbehandlung dar. Typ-II-Endoleaks weisen in der Mehrzahl einen benignen Verlauf auf. Wenn kein Wachstum des Aneurysmasacks erfolgt, kann eine Nachkontrolle im gewohnten Intervall durchgeführt werden. Typ-II-Endoleaks mit assoziiertem Wachstum des Aneurysmasacks können durch Embolisation der verantwortlichen Gefäße behandelt werden. Ob eine Behandlung immer durchgeführt werden muss, ist umstritten. Eine Behandlungsindikation von einem Typ-II-Endoleak mit wachsendem Aneurysmasack ist jedoch gegeben, wenn durch eine Verkürzung des Aneurysmahalses ein sekundäres Typ-I-Endoleak droht. Typ-I-Endoleaks stellen die Hauptlimitation der Stentgraft-Therapie dar. Die beste Prävention eines Typ-I-Endoleaks ist die Bereitstellung einer adäquaten proximalen Landezone. Dies kann durchaus bedeuten, dass fenestrierte Stentgrafts verwendet werden müssen. Die Verwendung von Schrauben oder anderen Fixationsinstrumenten zur sicheren Behandlung auch kurzer Hälse ist derzeit noch in der Studienphase.

Abstract
Background: Aneurysm shrinkage has been proposed as a marker of successful endovascular aneurysm repair (EVAR). We evaluated the impact of sac shrinkage on secondary interventions, on survival and its association with endoleaks, and on compliance with instructions for use (IFU). Methods: This observational retrospective study was conducted on all consecutive patients receiving EVAR for an infrarenal abdominal aortic aneurysm (AAA) using exclusively Endurant II/IIs endograft from 2014 to 2018. Sixty patients were entered in the study. Aneurysm sac shrinkage was defined as decrease ≥5 mm of the maximum aortic diameter. Univariate methods and Kaplan–Meier plots assessed the potential impact of shrinkage. Results: Twenty-six patients (43.3%) experienced shrinkage at one year, and thirty-four (56.7%) had no shrinkage. Shrinkage was not significantly associated with any demographics or morbidity, except hypertension (p = 0.01). No aneurysm characteristics were associated with shrinkage. Non-compliance with instructions for use (IFU) in 13 patients (21.6%) was not associated with shrinkage. Three years after EVAR, freedom from secondary intervention was 85 ± 2% for the entire series, 92.3 ± 5.0% for the shrinkage group and 83.3 ± 9% for the no-shrinkage group (Logrank: p = 0.49). Survival at 3 years was not significantly different between the two groups (85.9 ± 7.0% vs. 79.0 ± 9.0%, Logrank; p = 0.59). Strict compliance with IFU was associated with less reinterventions at 3 years (92.1 ± 5.9% vs. 73.8 ± 15%, Logrank: p = 0.03). Similarly, survival at 3 years did not significantly differ between strict compliance with IFU and non-compliance (81.8 ± 7.0% vs. 78.6 ± 13.0%, Logrank; p = 0.32). Conclusion: This study suggests that shrinkage ≥5 mm at 1-year is not significantly associated with a better survival rate or a lower risk of secondary intervention than no-shrinkage. In this series, the risk of secondary intervention regardless of shrinkage seems to be linked more to non-compliance with IFU. Considering the small number of patients, these results must be confirmed by extensive prospective studies.

Abstract
BACKGROUND The aim of this study is to evaluate if ilio-femoral calcium score (CS) combined with Glasgow Aneurysm Score (GAS) can improve the prediction of long-term survival after EVAR. METHODS All the patients who underwent infrarenal endovascular aortic repair (EVAR) for non-ruptured AAA between January 2004 and December 2012 at a tertiary referral center were retrospectively included if the preoperative imaging was of sufficient quality and they had survived for more than 30 days. Pre-operative non-contrast enhanced CT were used to measure ilio-femoral calcium score using dedicated postprocessing software. GAS was calculated and patients were divided into low or high GAS by a cutoff of 80. RESULTS 288 out of 500 patients were included in the study with no difference in survival compared to excluded patients (P = .529). Patients were followed-up for a median of 7 (4 - 9) years. GAS correlated positively with ilio-femoral calcium score (r = .123; P = .037). One hundred thirty-five patients (46,9 %) had low GAS, and 153 (53,1 %) had high GAS. Patients with high GAS had lower survival compared to the ones with low GAS (P ≤ .0001). GAS was associated with long-term mortality in a uni- and multivariate regression (P = < .0001 and P = < .0001). Ilio-femoral calcium score was significantly associated with mortality in the group with low GAS (P = .028), but not in the group with high GAS (P = .297). Significance retained in multivariate regression analysis (P = .029). Moreover, in the low GAS group, iliofemoral calcium score was further divided in high and low according to the median. Patients with high calcium score had lower survival compared to the ones with low calcium score ( P = .047). CONCLUSIONS Long-term survival in patients who have had infrarenal EVAR can be predicted by the clinically based Glasgow Aneurysm Score. Measuring the ilio-femoral calcium score preoperatively may refine GAS assessment in low-risk patients.

Abstract
PURPOSE To compare the long-term outcomes of the most widely used third-generation stent grafts, the Endurant and Excluder stent grafts, in Japanese patients using a multicenter registry. MATERIALS AND METHODS A retrospective analysis of endovascular aneurysm repairs for abdominal aortic and iliac artery aneurysms using either the Endurant or the Excluder stent grafts from January 2012 to July 2019 at 10 Japanese hospitals was performed. RESULTS A total of 332 and 378 repairs using the Endurant and Excluder stent grafts, respectively, were analyzed. Although the patients' characteristics were generally similar in the two groups, the Endurant group exhibited significantly shorter (Endurant: 31.5±18.6 mm, Excluder: 37.4±21.0 mm; p<0.001), larger (Endurant: 22.4±4.2 mm, Excluder: 21.7±3.8 mm; p=0.029), and more reversed tapered (Endurant: 12.1%, Excluder: 5.8%; p=0.003) proximal necks. The incidence of instructions for use (IFU) violations was similar between the two groups (Endurant: 59.0%, Excluder: 54.5%; p=0.223). However, the Endurant group had significantly more proximal neck-related IFU violations (54.1% and 46.3%, respectively; p=0.039), more access-related IFU violations (8.1% and 4.0%, respectively; p=0.019), and fewer bilateral hypogastric artery embolizations (5.1% and 9.3%, respectively; p=0.035) compared with the Excluder group. The incidence of intraoperative (Endurant: 3.6%, Excluder: 3.7%; p=0.950) and perioperative complications (Endurant: 3.6%, Excluder: 3.4%, p=0.899) was equivalent in the two groups. However, there was a significantly higher incidence of postoperative type II endoleaks in the Excluder group (Endurant: 28%, Excluder: 46.0%, p<0.001). Aneurysm sac regression was more frequent in the Endurant group (Endurant: 40.7%, Excluder: 31.7%, p=0.013). The Endurant group also had significantly higher rates of sac increase (Endurant: 13.0%, Excluder: 7.7%, p=0.020). Kaplan-Meier curve and log-rank analyses revealed no statistical differences in late complications (p=0.868) and overall survival (p=0.926). CONCLUSIONS There were no statistically significant differences between the Endurant and the Excluder stent grafts in terms of intraoperative, perioperative, and late complication rates; however, the anatomical characteristics of the patients were significantly different.

Abstract
OBJECTIVES Current guidelines recommend initial postoperative follow-up with computed tomography angiography (CTA) after endovascular aneurysm repair (EVAR). However, CTA has risks associated with ionizing radiations and nephrotoxic contrast agents. We investigated possibilities to replace the initial postoperative CTA with contrast enhanced duplex ultrasound (CE-DUS) in selected patients. METHODS Out of the 273 consecutive patients who underwent EVAR, 173 were excluded and the 100 patients who underwent CTA and CE-DUS imaging concurrently (≤1 month interval between CTA and CE-DUS imaging) within 60 days after EVAR were analyzed. Patients who underwent EVAR outside the manufacturer's instructions for use or who had endoleaks discovered on intraoperative angiography were classified as the high-risk group, otherwise, they were classified as the low-risk group. Measurements of diagnostic values of CE-DUS related to the detection of complications were calculated using CTA as the gold standard. McNemar's test was performed to compare these values and Pearson correlation coefficient was derived to compare CE-DUS measurements of sac diameters with CTA. RESULTS In the low-risk group, no difference was observed between CE-DUS and CTA in the detection of EVAR-related complications (sensitivity = 0.95, specificity = 0.93). In the high-risk group, CE-DUS was not as accurate as CTA for the detection of overall EVAR-related complications (sensitivity = 0.57, specificity = 0.86, p = 0.04) and for the detection of complications other than endoleaks (p = 0.02). Regarding sac diameter measurement, there was good agreement between CE-DUS and CTA (r = 0.92, p < 0.001). CONCLUSIONS First postoperative CE-DUS was reliable for the evaluation of EVAR-related complications compared to CTA in selected patients. Individualized EVAR follow-up strategy using CE-DUS based on the initial risk of EVAR-related complications should be considered.

Abstract
OBJECTIVE Endovascular aneurysm repair (EVAR) has become a standard treatment method for abdominal aortic aneurysms (AAA). Endovascular device manufacturers have defined specific anatomic criteria for aneurysm characteristics to be observed as instructions for use (IFU) with specific grafts. In clinical practice, the prevalence of performing EVAR outside the IFU is high. This study aims to determine the impact of IFU criteria non-adherence on outcomes. METHODS Patients undergoing EVAR for an infrarenal AAA between 2005 and 2013 were included. IFU non-adherence was defined as any violation of device-specific IFU criteria and was compared to IFU adherence. Primary outcomes were all-cause mortality, aneurysm-related mortality, AAA ruptures, graft-related adverse events (GRAEs), including limb-related adverse events, and type Ia endoleaks. Secondarily, the aim was to study whether the prevalence of EVAR performed outside the IFU has increased over time. RESULTS A total of 258 patients were included, 144 (55.8%) of whom were treated according to the IFU criteria and 114 (44.2%) outside the criteria. In the IFU non-adherence group, all-cause mortality (HR 1.39, 95% CI 1.02-1.89, p = .037) and aneurysm-related mortality (HR 5.1, 95% CI 1.4-18.6, p = .015) were higher, as were the incidences of AAA ruptures (HR 5.4, 95 % CI 1.1-26.6, p = .036) and GRAEs (HR 1.7, 95% CI 1.1-2.8, p = .025). No significant association was found between type Ia endoleak and neck-related IFU or limb-related adverse events and iliac-related IFU. However, neck length was a risk factor for a type Ia endoleak (HR 18.2, 95% CI 6.3-52.2, p < .001), aneurysm-related mortality (HR=8.7, 95% CI 1.8-41.6, p = .007), rupture (HR= 21.7, 95% CI 2.8-166, p = .003), and GRAEs (HR 4.4, 95% CI 2.0-9.7, p < .001). An IFU violation regarding the neck angulation was also a risk factor for all-cause mortality (HR 2.0, 95% CI 1.1-3.7, p = .032), aneurysm-related mortality (HR 7.6, 95% CI 1.4-42.8, p = .021), AAA rupture (HR 79.4, 95% CI 6.3-999, p = .001), and GRAEs (HR 4.3, 95% CI 1.9-9.5, p < .001). The prevalence of EVAR performed outside the IFU did not increase over time. CONCLUSIONS Performing EVAR outside the IFU has a negative effect on outcomes, including all-cause mortality, aneurysm-related mortality, ruptures, and graft-related adverse events. Neck angulation and neck length seem to be the most crucial aneurysm characteristics.

Abstract
Objectives Intraluminal prosthetic graft thrombus (IPT) following Endovascular Aneurysm Repair (EVAR) can have serious consequences. The aim of this study was to assess the prevalence of IPT and to identify the risk factors for its formation and progression. Methods This was a retrospective study of 258 patients who had EVAR between 2015 and 2018. Demographic data, comorbidities, operative data, antithrombotic therapy, CT anatomical data, IPT characteristics (site, regression, and progression), and re-interventions were collected. Univariable analysis followed by multivariable logistic regression and Cox regression were used for data analysis. Results The mean age of patients was 76 years (range 55-95) and 27 (10.5 %) were females. IPT was present in 26 patients (10.1%) with a median time to occurrence of six (range 1- - 24) months. Of the group that developed IPT, six (23.1 %) developed symptoms and two (7.7%) had re-interventions. Multivariable logistic regression analysis revealed peripheral arterial disease to be associated with the formation of IPT (OR 7.4, 95% CI 1.6-35.3, p = 0.02) and escalation of antithrombotic therapy was associated with regression or prevention of progression of IPT (OR 0.1, 95% CI 0.0-0.6, p = 0.01). Conclusion PAD is associated with the formation of IPT after EVAR and warrants consideration of escalation of antithrombotic therapy to prevent further progression and complications.

Abstract
OBJECTIVE The effect of suprarenal fixation (SR) compared to infrarenal fixation (IR) on renal function during endovascular aneurysm repair (EVAR) remains controversial. This study aims to compare the renal outcomes between fixation types in short- and long-term follow-up. METHODS Patients undergoing EVAR for infrarenal abdominal aortic aneurysm between 2005 and 2013 were included. Estimated glomerular filtration rate (eGFR) was measured at baseline and during a follow-up of 5 years. A decline in renal function was defined as a ≥ 20% decrease in eGFR. Changes in eGFR were compared between SR and IR groups at 1-7 days, 30 days, and 1-5 years postoperatively. Preoperative renal insufficiency was defined as eGFR < 60mL/min/1.73m2, and those patients were included in the subanalyses. RESULTS A total of 358 patients were included. Among these, 267 (74.6%) had SR and 91 (25.4%) had IR fixation. A decline in renal function occurred more commonly after SR than after IR in 1-7 days postoperatively (p = .009), but no difference was noticed at 30 days and 1-5 years. Regardless of the fixation method, renal function steadily decreased steadily over time after EVAR (estimate -3.13 per a year, 95% confidence interval -3.40- -2.85, p < .001). Patients with pre-existing renal insufficiency were included in subgroup analyses, and those with SR were more often found to have a decline in eGFR 5 years postoperatively than their counterparts with IR (59.5% vs 20.0%, p = .036). CONCLUSION An immediate postoperative decline in renal function was seen more often after SR fixation than IR fixation but this difference was transient. SR fixation is a safe method for patients with normal renal function. Long-term results seems to favor IR over SR in patients with pre-existing renal insufficiency.
