Abstract
BACKGROUND Epidemiological data on ruptured aortic aneurysms from large-scale studies are scarce. The aims of this study were to: clarify the clinical course of ruptured aortic aneurysms; identify aneurysm site-specific therapies and outcomes; and determine the clinical course of patients receiving conservative therapy. METHODS AND RESULTS Using the Tokyo Acute Aortic Super Network database, we retrospectively analyzed 544 patients (mean [±SD] age 78±10 years; 70% male) with ruptured non-dissecting aortic aneurysms (AAs) after excluding those with impending rupture. Patient characteristics, status on admission, therapeutic strategy, and outcomes were evaluated. Shock or pulselessness on admission were observed in 45% of all patients. Conservative therapy, endovascular therapy (EVT), and open surgery (OS) accounted for 32%, 23%, and 42% of cases, respectively, with corresponding mortality rates of 93%, 30%, and 29%. The overall in-hospital mortality rate was 50%. The prevalence of pulselessness was highest (48%) in the ruptured ascending AA group, and in-hospital mortality was the highest (70%) in the ruptured thoracoabdominal AA group. Multivariable logistic regression analysis indicated in-hospital mortality was positively associated with pulselessness (odds ratio [OR] 10.12; 95% confidence interval [CI] 4.09-25.07), and negatively associated with invasive therapy (EVT and OS; OR 0.11; 95% CI 0.06-0.20). CONCLUSIONS The outcomes of ruptured AAs remain poor; emergency invasive therapy is essential to save lives, although it remains challenging to reduce the risk of death.

Abstract
OBJECTIVE OR BACKGROUND To report the investigational device exemption (IDE) study 1-year clinical outcomes of the high neck angulation (HNA) substudy of the GORE® EXCLUDER® Conformable AAA Endoprosthesis (EXCC) for treatment of infrarenal abdominal aortic aneurysms (AAA). METHODS This study is a prospective, multicenter clinical trial conducted in the United States and included core laboratory assessment of imaging and independent event adjudication. Anatomic criteria for enrollment in the HNA substudy included infrarenal aortic neck angulation >60° and ≤90° with aortic neck length ≥10 mm. Primary safety endpoints included blood loss >1000 mL, death, stroke, myocardial infarction, bowel ischemia, paraplegia, respiratory failure, renal failure, and thromboembolic events. Primary effectiveness endpoints included technical success, absence from Type I and III endoleak, migration (≥10 mm), sac enlargement (≥5 mm), sac rupture, and conversion to open repair. RESULTS Between January 2018 and February 2022, 95 patients were enrolled in the HNA substudy across 35 sites. Of the 95 patients, 71 (74.7%) were male and the cohort average age was 74.4 years old. The mean infrarenal proximal aortic neck angle was 71.6° and mean AAA size was 62.9 mm. Overall technical success was achieved in 93 (97.9%) patients. Freedom from a primary safety endpoint through 30 days was 96.7%; 3 (3.3%) patients had blood loss >1000 mL. Freedom from the primary effectiveness at 12 months was achieved in 94.8%. Four (4.3%) patients had Type IA endoleak; intervention after the procedure was not required and no subsequent interventions or sac enlargement were noted in these patients. At 12 months, 29 (39.7%) patients experienced a Type II endoleak and 1 (1.3%) patient experienced AAA sac expansion ≥5mm. Through 12 months, 1 (1.3%) patient had a conversion to open surgical repair. There were no aneurysm-related deaths, ruptures, or migration through 12 months. CONCLUSIONS The IDE study demonstrates safety and effectiveness of the EXCC device in AAA with highly angulated necks (>60° and ≤90°) are preserved at the 12-month follow-up.

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

Abstract
OBJECTIVE As a result of conflicting, inadequate or controversial data in the literature, several issues concerning the management of patients with abdominal aortic aneurysms (AAAs) remain unanswered. The aim of this international, expert-based Delphi consensus document was to provide some guidance for clinicians on these controversial topics. METHODS A three-round Delphi consensus document was produced with 44 experts on 6 prespecified topics regarding the management of AAAs. All answers were provided anonymously. The response rate for each round was 100%. RESULTS Most participants (42 of 44 [95.4%]) agreed that a minimum case volume per year is essential (or probably essential) for a center to offer open or endovascular AAA repair (EVAR). Furthermore, 33 of 44 (75.0%) believed that AAA screening programs are (probably) still clinically effective and cost effective. Additionally, most panelists (36 of 44 [81.9%]) voted that surveillance after EVAR should be (or should probably be) lifelong. Finally, 35 of 44 participants (79.7%) thought that women smokers should (or should probably/possibly) be considered for screening at 65 years of age, similar to men. No consensus was achieved regarding lowering the threshold for AAA repair and the need for deep venous thrombosis prophylaxis in patients undergoing EVAR. CONCLUSIONS This expert-based Delphi consensus document provides guidance for clinicians regarding specific unresolved issues. Consensus could not be achieved on some topics, highlighting the need for further research in those areas.

Long Term Outcomes of the Gore Excluder Low Permeability Endoprosthesis for the Treatment of Infrarenal Aortic Aneurysms. Eur J Vasc Endovasc Surg 2024; 68:18-27. [PMID: 38527519 DOI: 10.1016/j.ejvs.2024.03.028] [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: 09/07/2023] [Revised: 02/23/2024] [Accepted: 03/21/2024] [Indexed: 03/27/2024]
Abstract
OBJECTIVE This study evaluated the long term outcomes of endovascular aneurysm repair using the Gore Excluder Low Permeability (LP) endoprosthesis across high volume Dutch hospitals. METHODS A retrospective analysis was conducted of patients treated with the Excluder LP for infrarenal abdominal aortic aneurysm (AAA) in four hospitals between 2004 and 2017. Primary outcomes were overall survival, freedom from re-interventions (overall, inside and outside instructions for use, IFU), and AAA sac dynamics: growth (> 5 mm), stabilisation, and regression (< 5 mm). Secondary outcomes were technical success (device deployment), procedural parameters, and re-interventions. Follow up visits were extracted from patient files, with imaging assessed for complications and AAA diameter. RESULTS Five hundred and fourteen patients were enrolled, with a median (IQR) follow up of 5.0 (2.9, 6.9) years. Survival rates were 94.0% at one year, 73.0% at five years, and 37.0% at 10 years, with freedom from re-interventions of 89.0%, 79.0%, and 71.0%, respectively. 37.9% were treated outside IFU, leading to significantly more re-interventions over 10 years compared with those treated inside IFU (36.0% vs. 25.0%, respectively; p = .044). The aneurysm sac regressed by 53.5% at one year, 65.8% at five years, and 77.8% at 10 years, and grew by 9.8%, 14.3%, and 22.2%, respectively. Patients with one year sac growth had significantly worse survival (p = .047). Seven patients (1.4%) had a ruptured aneurysm during follow up. Over 15 years, type 1a endoleak occurred in 5.3%, type 1b in 3.1%, type 3 in 1.9%, type 4 in 0.2%, and type 2 in 35.6% of patients. CONCLUSION This multicentre study of real world endovascular aneurysm repair data using the Gore Excluder LP endoprosthesis demonstrated robust long term survival and re-intervention rates, despite 37.9% of patients being treated outside IFU, with type 4 endoleak being rare. Treatment outside IFU significantly increased re-intervention rates and one year sac growth was associated with statistically significantly worse survival.

Long-term costs to Medicare associated with endovascular and open repairs of infrarenal and complex abdominal aortic aneurysms. J Vasc Surg 2024; 80:98-106. [PMID: 38490605 DOI: 10.1016/j.jvs.2024.03.017] [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: 10/17/2023] [Revised: 03/04/2024] [Accepted: 03/07/2024] [Indexed: 03/17/2024]
Abstract
OBJECTIVE The vast majority of patients with abdominal aortic aneurysms (AAAs) undergoing repairs receive endovascular interventions (EVARs) instead of open operations (OARs). Although EVARs have better short-term outcomes, OARs have improved longer-term durability and require less radiographic follow-up and monitoring, which may have significant implications on health care economics surrounding provision of AAA care nationally. Herein, we compared costs associated with EVAR and OAR of both infrarenal and complex AAAs. METHODS We examined patients undergoing index elective EVARs or OARs of infrarenal and complex AAAs in the 2014-2019 Vascular Quality Initiative-Vascular Implant Surveillance and Interventional Outcomes Network (VQI-VISION) dataset. We defined overall costs as the aggregated longitudinal costs associated with: (1) the index surgery; (2) reinterventions; and (3) imaging tests. We evaluated overall costs up to 5 years after infrarenal AAA repair and 3 years for complex AAA repair. Multivariable regressions adjusted for case-mix when evaluating cost differences between EVARs vs OARs. RESULTS We identified 23,746 infrarenal AAA repairs (8.7% OAR, 91% EVAR) and 2279 complex AAA repairs (69% OAR, 31% EVAR). In both cohorts, patients undergoing EVARs were more likely to be older and have more comorbidities. The cost for the index procedure for EVARs relative to OARs was lower for infrarenal AAAs ($32,440 vs $37,488; P < .01) but higher among complex AAAs ($48,870 vs $44,530; P < .01). EVARs had higher annual imaging and reintervention costs during each of the 5 postoperative years for infrarenal aneurysms and the 3 postoperative years for complex aneurysms. Among patients undergoing infrarenal AAA repairs who survived 5 years, the total 5-year cost of EVARs was similar to that of OARs ($35,858 vs $34,212; -$223 [95% confidence interval (CI), -$3042 to $2596]). For complex AAA repairs, the total cost at 3 years of EVARs was greater than OARs ($64,492 vs $42,212; +$9860 [95% CI, $5835-$13,885]). For patients receiving EVARs for complex aneurysms, physician-modified endovascular grafts had higher index procedure costs ($55,835 vs $47,064; P < .01) although similar total costs on adjusted analyses (+$1856 [95% CI, -$7997 to $11,710]; P = .70) relative to Zenith fenestrated endovascular grafts among those that were alive at 3 years. CONCLUSIONS Longer-term costs associated with EVARs are lower for infrarenal AAAs but higher for complex AAAs relative to OARs, driven by reintervention and imaging costs. Further analyses to characterize the financial viability of EVARs for both infrarenal and complex AAAs should evaluate hospital margins and anticipated changes in costs of devices.

Abstract
CASE We present a case of a 66-year-old man with lumbar vertebral body erosions after glue embolization of a Type II endoleak secondary to endovascular repair of an infrarenal aortic aneurysm. Multiple biopsies of the affected vertebrae were culture-negative confirming no evidence of infection. He underwent posterior spinal fusion from L2 to L5 with complete resolution of mechanical low back pain and improved functional outcomes. CONCLUSION Vertebral body osseous erosion is a rare complication of aortic endoleak intervention that can be successfully treated with spinal fusion.

Abstract
HighlightsNo studies have been published comparing the treatment of abdominal aortic aneurysms in residents of the Central Asian region and Russia ≥80 years of age. Differences in the number of emergency and planned operations in the studied countries have been revealed. Thus, despite the predominance of planned operations in the total structure, the frequency of emergency operations related to AAA rupture is extremely high, which is associated with a large aneurysm diameter. In Tajikistan there is no difference in mortality between patients of different age groups, while in the Russian Federation this indicator is higher among persons up to and including 79 years of age. The number of comorbidities is high in both countries. AbstractAim. To analyse the demography, the structure of comorbidity and mortality in the treatment of patients with AAA with an age priority of study up to 79 and over 80 years old in Russia and Tajikistan.Methods. A retrospective, comparative study of patients with infrarenal AAA who underwent endovascular repair of abdominal aortic aneurysm (EAAA) or open AAA reconstruction during the period from 2011 to 2015 at the clinic of Russian State Medical University named after N.N. acad. I.P. Pavlov in Ryazan, Russia and in the RSCCS, Dushanbe, Tajikistan (2011–2017). The study included 226 patients, 60 from Dushanbe (Tajikistan) and 166 from Ryazan (Russia). The study examined age, gender, comorbidities: diabetes, coronary heart disease (CHD), hypertension, COPD, smoking, as well as abdominal aortic diameter and 30-day mortality.Results. There are significantly more male patients with AAA in both countries. The number of comorbidities (CHD, hypertension, COPD, diabetes) per patient reaches 2.30 in Russia and 2.35 in Tajikistan. The number of patients older than 80 years in Russia was 11.4% and in Tajikistan 23.7% of the total number of patients operated on for AAA. In all countries, patients with AAA, inclusive, up to 79 years of age are statistically significantly more than patients 80 years of age or older. There are statistically significantly more patients under 79 in Russia. The age of patients after 80 is statistically significantly higher among patients from Russia. The number of emergency operations in all countries is significantly lower than elective operations, but still emergency operations were performed in almost one third of cases. In the group of patients up to 79 years old, the smallest number of emergency operations due to aneurysm ruptures was found in Russia. In the group of patients aged 80 years old and over, the smallest number of elective surgeries was found in Russia. The AAA diameter in patients from the two countries did not differ statistically significantly and amounted to 60.0 [48.0; 75.0] and 57.0 [54.0; 61.5] mm. in RF and RT, respectively (p > 0.05). In the age category up to 79 years old, there were statistically significantly fewer men in Tajikistan than in Russia. However, in the category after 80 years old there are statistically significantly fewer men in Russia than in Tajikistan. In Tajikistan, there was no difference in mortality between ages, however, in the Russian Federation it is higher in patients up to 79 years of age inclusive.Conclusion. As the results of the study showed, the average age of all patients with AAA was elderly, and the number of patients older than 80 years was 11.4% and 23.4% in Russia and Tajikistan, respectively. The group of patients over 80 years of age, according to the criterion of average age, was older among patients from Russia. It is important that the number of emergency operations in all countries is significantly lower than planned, but emergency operations were performed in almost one third of cases. In addition, the number of high-risk comorbidities is high in both countries.

The rise of endovascular repair for abdominal, thoracoabdominal, and thoracic aortic aneurysms. J Vasc Surg 2024:S0741-5214(24)01482-4. [PMID: 38942397 DOI: 10.1016/j.jvs.2024.06.165] [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: 03/24/2024] [Revised: 06/18/2024] [Accepted: 06/23/2024] [Indexed: 06/30/2024]
Abstract
BACKGROUND Given changes in intervention guidelines and the growing popularity of endovascular treatment for aortic aneurysms, we examined the trends in admissions and repairs of abdominal aortic aneurysms (AAAs), thoracoabdominal aortic aneurysms (TAAAs), and thoracic aortic aneurysms (TAAs). METHODS We identified all patients admitted with ruptured aortic aneurysms and intact aortic aneurysms repaired in the Nationwide Inpatient Sample between 2004 and 2019. We then examined the use of open, endovascular, and complex endovascular repair (OAR, EVAR, and cEVAR) for each aortic aneurysm location (AAA, TAAA, and TAA), alongside their resulting in-hospital mortality, over time. cEVAR included branched, fenestrated, and physician-modified endografts. RESULTS 715,570 patients were identified with AAA (87% intact repairs and 13% rupture admissions). Both intact AAA repairs and ruptured AAA admissions decreased significantly between 2004 and 2019 (intact 41,060-34,215, P < .01; ruptured 7175-4625, P = .02). Of all AAA repairs performed in a given year, the use of EVAR increased (2004-2019: intact 45%-66%, P < .01; ruptured 10%-55%, P < .01) as well as cEVAR (2010-2019: intact 0%-23%, P < .01; ruptured 0%-14%, P < .01). Mortality after EVAR of intact AAAs decreased significantly by 29% (2004-2019, 0.73%-0.52%, P < .01), whereas mortality after OAR increased significantly by 16% (2004-2019, 4.4%-5.1%, P < .01). In the study, 27,443 patients were identified with TAAA (80% intact and 20% ruptured). In the same period, intact TAAA repairs trended upward (2004-2019, 1435-1640, P = .055), and cEVAR became the most common approach (2004-2019, 3.8%-72%, P = .055). A total of 141,651 patients were identified with ascending, arch, or descending TAAs (90% intact and 10% ruptured). Intact TAA repairs increased significantly (2004-2019, 4380-10,855, P < .01). From 2017 to 2019, the mortality after OAR of descending TAAs increased and mortality after thoracic endovascular aneurysm repair decreased (2017-2019, OAR 1.6%-3.1%; thoracic endovascular aneurysm repair 5.2%-3.8%). CONCLUSIONS Both intact AAA repairs and ruptured AAA admissions significantly decreased between 2004 and 2019. The use of endovascular techniques for the repair of all aortic aneurysm locations, both intact and ruptured, increased over the past two decades. Most recently in 2019, 89% of intact AAA repairs, infrarenal through suprarenal, were endovascular (EVAR or cEVAR, respectively). cEVAR alone increased to 23% of intact AAA repairs in 2019, from 0% a decade earlier. In this period of innovation, with many new options to repair aortic aneurysms while maintaining arterial branches, endovascular repair is now used for the majority of all intact aortic aneurysm repairs. Long-term data are needed to evaluate the durability of these procedures.

Abstract
Objective: In patients with abdominal aortic aneurysm (AAA), early detection and optimal elective treatment before rupture are desirable. In the absence of an established public screening system, opportunistic screening during ultrasound examination for another purpose might be efficacious. The aim of this study was to evaluate the efficacy of opportunistic screening for AAA. Methods: This prospective multicenter observational study enrolled patients who were scheduled to undergo ultrasound for reasons other than AAA. After the ultrasound for the original purpose, evaluation of the abdominal aorta was added. If the abdominal aorta was clear enough for measurement, its diameter and shape were recorded. Furthermore, information on comorbidities was collected for each patient. Results: A total of 10325 patients (echocardiography: 6150; abdominal ultrasound: 4162) from 16 institutions were enrolled. The abdominal aorta was well visualized in 92.9% of patients who underwent echocardiography. Among 9791 patients, AAA was diagnosed in 122 (1.3%) (107 fusiform and 15 saccular), with a diameter range of 30-63 mm. The diagnostic rate increased with age. On multivariate analysis, older age, male sex, coronary artery disease, peripheral arterial disease, and smoking habituation were the risk factors for AAA. Conclusion: Opportunistic screening for AAA was efficacious.

Abstract
BACKGROUND Research on degenerative abdominal aortic aneurysms (AAA) is hampered by complex pathophysiology, sub-optimal pre-clinical models, and lack of effective medical therapies. In addition, trustworthiness of existing epidemiological data is impaired by elements of ambiguity, inaccuracy, and inconsistency. Our aim is to foster debate concerning the trustworthiness of AAA epidemiological data and to discuss potential solutions. METHODS We searched the literature from the last five decades for relevant epidemiological data concerning AAA development, rupture, and repair. We then discussed the main issues burdening existing AAA epidemiological figures and proposed suggestions potentially beneficial to AAA diagnosis, prognostication, and management. RESULTS Recent data suggest a heterogeneous scenario concerning AAA epidemiology with rates markedly varying by country and study cohorts. Overall, AAA prevalence seems to be decreasing worldwide while mortality is apparently increasing regardless of recent improvements in aortic-repair techniques. Prevalence and mortality are decreasing in high-income countries, whereas low-income countries show an increase in both. However, several pieces of information are missing or outdated, thus systematic renewal is necessary. Current AAA definition and surgical criteria do not consider inter-individual variability of baseline aortic size, further decreasing their reliability. CONCLUSIONS Switching from flat aortic-size thresholds to relative aortic indices would improve epidemiological trustworthiness regarding AAAs. Aortometry standardization focusing on simplicity, univocity, and accuracy is crucial. A patient-tailored approach integrating clinical data, multi-adjusted indices, and imaging parameters is desirable. Several novel imaging modalities boast promising profiles for investigating the aortic wall. New contrast agents, computational analyses, and artificial intelligence-powered software could provide further improvements.

Abstract
Introduction As surgical technologies grow, so too do demands on surgical trainees to master increasing numbers of skill sets. With the rise of endovascular surgery, trainees have fewer opportunities to practice open vascular techniques in the operating room. Simulation can bridge this gap. However, existing published open vascular simulation curricula are basic or based on expensive models. Methods We iteratively developed an open vascular skills curriculum for second-year surgery residents comprising six 2-hour sessions. We refined the curriculum based on feedback from learners and faculty. The curriculum required skilled facilitators, vascular instruments, and tissue models. We evaluated the latest iteration with a survey and by assessing participants' technical skills using the Objective Structured Assessment of Technical Skills (OSATS) form. Results Over the past 10 years, 101 residents have participated in the curriculum. Nine of 13 residents who participated in the latest curricular iteration completed the survey. All respondents rated the sessions as excellent and strongly agreed that they had improved their abilities to perform anastomoses with tissue and prosthetic. Facilitators completed 18 OSATS forms for residents in the fifth and sixth sessions of the latest iteration. Residents scored well overall, with a median 26.5 (interquartile range: 24-29) out of a possible score of 35, with highest scores on knowledge of instruments. Discussion This simulation-based curriculum facilitates open vascular surgical skill acquisition among surgery residents. The curriculum allows residents to acquire critical vascular skills that are challenging to learn in an increasingly demanding operative setting.

Abstract
BACKGROUND To estimate the impact of anesthetic conduct, alone and in combination with the type of femoral access, on early results after endovascular aneurysm repair (EVAR). METHODS A retrospective multicenter analysis on patients undergoing elective standard EVAR at four academic centers was performed. Patients undergoing the procedure through either local or general anesthesia were compared. Comparative subanalyses of the two groups were performed for the type of femoral access to evaluate further impact on outcomes. RESULTS Five hundred twenty-four patients underwent elective standard EVAR, of which 207 (39.5%) under general anesthesia and 317 (60.5%) under local anesthesia. Patients who underwent general anesthesia had higher 30-day mortality rates (3.4% vs. 0.3%, P=0.005), as well as slightly worse 30-day major systemic complication rates (8.2% vs. 5.4%, P=0.195). There were no differences in terms of reinterventions (2.1% vs. 2.5%, P=0.768) and aneurysm-related mortality (0% vs. 0.4%, P=0.422) at one year. Total intervention times were significantly longer in the general anesthesia group (126 vs. 89 minutes, P=0.001), as well as the total length of hospital stay (7.6 vs. 5.3 days, P=0.007). At subanalyses, the combination of local anesthesia with bilateral percutaneous femoral access further improved 30-day outcomes and determined an additional reduction in total intervention times and ICU stays. CONCLUSIONS EVAR performed under local anesthesia has a significantly better impact on early results when compared to general anesthesia. Combining percutaneous bilateral femoral access to local anesthesia reduced procedural times, ICU stays and consequently improved early results.

Abstract
Successful endovascular aneurysm repair can be achieved with favorable aortic and iliac arterial anatomies. However, patients with challenging iliac anatomy, such as stenotic, calcified, tortuous arteries, or concomitant iliac artery aneurysms, are commonly encountered. Such a hostile iliac anatomy increases the risk of intraprocedural complications and worsens long-term outcomes. This review addresses various technical options for treating patients with a hostile iliac anatomy, including innovative endovascular solutions, physician-modified endografts, and hybrid procedures. These considerations demonstrate the wide scope of therapies that may be offered to patients with an unfavorable iliac anatomy.

Abstract
BACKGROUND Elective endovascular aneurysm repair (EVAR) can be performed via local anesthetics and/or regional (epidural or spinal) anesthesia (locoregional [LR]), versus general anesthesia (GA), conferring reduced intensive care unit (ICU) and hospital stays. Current analyses fail to account for temporal changes in vascular practice. Therefore, this study aimed to confirm reductions in ICU and hospital stays among LR patients while accounting for changes in practice patterns. MATERIALS AND METHODS Using the Society for Vascular Surgery's Vascular Quality Initiative, elective EVARs from August 2003 to June 2021 were grouped into LR or GA. Outcomes included ICU admission and prolonged hospital stay (>2 d). Procedures were stratified into groups of 2 y periods, and outcomes were analyzed within each time period. Univariable and multivariate analyses were used to assess outcomes. RESULTS LR was associated with reduced ICU admissions (22.3% versus 32.1%, P < 0.001) and prolonged hospital stays (14.3% versus 7.9%, P < 0.001) overall. When stratified by year, LR maintained its association with reduced ICU admissions in 2014-2015 (21.8% versus 34.0%, P < 0.001), 2016-2017 (23.6% versus 31.6%, P < 0.001), 2018-2019 (18.5% versus 30.2%, P < 0.001), and 2020-2021 (15.8% versus 28.8%, P < 0.001), although this was highly facility dependent. LR was associated with fewer prolonged hospital stays in 2014-2015 (15.6% versus 20.4%, P = 0.001) and 2016-2017 (13.3% versus 16.6%, P = 0.006) but not after 2017. CONCLUSIONS GA and LR have similar rates of prolonged hospital stays after 2017, while LR anesthesia was associated with reduced rates of ICU admissions, although this is facility-dependent, providing a potential avenue for resource preservation in patients suitable for LR.

Modified Harborview Risk Score accurately predicts mortality for patients with ruptured abdominal aortic aneurysm. J Vasc Surg 2024; 79:555-561. [PMID: 37967587 DOI: 10.1016/j.jvs.2023.11.013] [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: 09/23/2023] [Revised: 11/05/2023] [Accepted: 11/07/2023] [Indexed: 11/17/2023]
Abstract
OBJECTIVE The modified Harborview Risk Score (HRS) is a simple measure initially derived from a single institutional dataset used to predict ruptured abdominal aortic aneurysm (rAAA) repair survival preoperatively using basic labs and vital signs collected upon presentation. However, validation of this widely applicable scoring system has not been performed. This study aims to validate this scoring system using a large multi-institutional database. METHODS All patients who underwent repair of an rAAA from 2011 to 2018 in the National Surgical Quality Improvement Program (NSQIP) and at a single academic medical center were included. The modified HRS was calculated by assigning 1 point for each of the following: age >76 years, creatinine >2 mg/dL, international normalized ratio >1.8, and any systolic blood pressure less than 70 mmHg. Assessment of the prediction model was then completed. Using a primary outcome measure of 30-day mortality, the receiver operating characteristic area under the curve was calculated. The discrimination between datasets was compared using a Delong test. Mortality rates for each score were compared between datasets using the Pearson χ2 test. Comparative analysis for patients with a score of 4 was limited due to a small sample size. RESULTS A total of 1536 patients were identified using NSQIP, and 163 patients were assessed in the institutional dataset. There were 518 patients with a score of 0 (455 NSQIP, 63 institutional), 676 patients with a score of 1 (617 NSQIP, 59 institutional), 391 patients with a score of 2 (364 NSQIP, 27 institutional), 106 with a score of 3 (93 NSQIP, 13 institutional), and 8 patients with a score of 4 (7 NSQIP, 1 institutional). No difference was found in the receiver operating characteristic area under the curves between datasets (P = .78). Thirty-day mortality was 10% NSQIP vs 22% institutional for a score of 0; 28% NSQIP vs 36% institutional for a score of 1; 41% NSQIP vs 44% institutional for a score of 2; 45% NSQIP vs 69% institutional for a score of 3; and 57% NSQIP vs 100% institutional for a score of 4. Score 0 was the only score with a significant mortality rate difference between datasets (P = .01). CONCLUSIONS The modified HRS is confirmed to be broadly applicable as a clinical decision-making tool for patients presenting with rAAAs. Therefore, this easily applicable model should be applied for all patients presenting with rAAAs to assist with provider and patient decision-making prior to proceeding with repair.

Kaminski C, Beardslee LA, Rajani R. Sensorized Endovascular Technologies: Additional Data to Enhance Decision-Making. Ann Vasc Surg 2024; 99:105-116. [PMID: 37922964 DOI: 10.1016/j.avsg.2023.10.001] [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: 06/07/2023] [Revised: 09/29/2023] [Accepted: 10/07/2023] [Indexed: 11/07/2023]
Abstract
BACKGROUND Current endovascular procedures rely mostly on anatomic information, guided by fluoroscopy, to perform interventions (i.e. angioplasty, stent placement, coils). However, the structural parameters provided by these imaging technologies do not provide any physiological data on either the disease state or efficacy of intervention. Additional endovascular tools are needed to collect physiologic and other both anatomic and nonanatomic data to further individualize endovascular interventions with the ultimate goal of improving patient outcomes. This review details the current state of the art for these sensorized endovascular technologies and details systems under development with the aim of identifying gaps and new directions. The objective of this review was to survey the Vascular Surgery literature, engineering literature, and commercially available products to determine what exists in terms of sensor-enabled endovascular devices and where gaps and opportunities exist for further sensor integration. METHODS Search terms were entered into search engines such as Google and Google Scholar to identify endovascular devices containing sensors. A variety of terms were used including directly search for items such as "sensor-enabled endovascular devices" and then also completing more refined searches bases on areas of interest (i.e. fractional flow reserve, navigation, retrograde endovascular balloon occlusion of the aorta, etc.). For the most part, systems were included where the sensor was mounted directly onto the catheter and implantable sensors such as those that have been investigated for use with stents have been excluded. RESULTS The authors were able to identify a body of literature in the area of endovascular devices that contain sensors to measure physiologic information. However, areas where additional sensing capabilities may be useful were identified. CONCLUSIONS Several different types of sensors and sensing systems were identified that have been integrated with endovascular catheters. Although a great deal of work has been done in this field, there are additional useful data that could be obtained from additional novel sensing technologies. Furthermore, significant effort needs to be allocated to carefully studying how these new technologies can be employed to actually improve patient outcomes.

One-year aneurysm-sac dynamics are associated with reinterventions and rupture following infrarenal endovascular aneurysm repair. J Vasc Surg 2024; 79:269-279. [PMID: 37844849 DOI: 10.1016/j.jvs.2023.10.006] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2023] [Revised: 10/07/2023] [Accepted: 10/11/2023] [Indexed: 10/18/2023]
Abstract
OBJECTIVE One-year aneurysm sac changes have previously been found to be associated with mortality and may have the potential to guide personalized follow-up following endovascular aneurysm repair (EVAR). In this study, we examined the association of these early sac changes with long-term reintervention and rupture. METHODS We identified all patients undergoing first-time EVAR for intact abdominal aortic aneurysm between 2003 and 2018 in the Vascular Quality Initiative with linkage to Medicare claims for long-term outcomes. We included patients with an imaging study at 1 year postoperatively. Aneurysm sac behavior was defined as per the Society for Vascular Surgery guidelines: stable sac (<5 mm change), sac regression (≥5 mm), and sac expansion (≥5 mm). Outcomes included mortality, reintervention, and rupture within 8 years, which were assessed with Kaplan-Meier methods and multivariable Cox regression analysis. Secondarily, we utilized polynomial spline interpolation to demonstrate the continuous relationship of diameter change to 8-year hazard of reintervention, rupture, or mortality as a composite outcome. RESULTS Of 31,185 EVAR patients, 16,102 (52%) had an imaging study at 1 year and were included in this study. At 1 year, 44% of sacs remained stable, 49% regressed, and 6.2% displayed expansion. Following risk adjustment, compared with a stable sac at 1 year, sac regression was associated with lower 8-year mortality (49% vs 53%; hazard ratio [HR], 0.92; 95% confidence interval [CI], 0.85-0.99; P = .036), reintervention rate (8.9% vs 15%; HR, 0.58; 95% CI, 0.50-0.68; P < .001), and rupture rate (2.0% vs 4.0%; HR, 0.45; 95%CI, 0.29-0.69; P < .001). Conversely, compared with a stable sac, sac expansion was associated with higher 8-year mortality (64% vs 53%; HR, 1.31; 95% CI, 1.14-1.51; P < .001) and reintervention rate (27% vs 15%; HR, 1.98; 95% CI, 1.57-2.51; P < .001), but similar risk of rupture (7.2% vs 4.0%; HR, 1.61; 95% CI, 0.88-2.96; P = .12). Polynomial spline interpolation demonstrated that, compared with no diameter change at 1 year, increased sac regression was associated with an incrementally lower risk of late outcomes, whereas increased sac expansion was associated with an incrementally higher risk of late outcomes. CONCLUSIONS Following EVAR, compared with a stable sac at 1-year imaging, sac regression and expansion are associated with a lower and higher risk respectively of long-term mortality, reinterventions, and ruptures. Moreover, the amount of regression or expansion seems to be incrementally associated with these late outcomes, too. Future studies are needed to determine how to improve 1-year sac regression, and whether it is safe to extend follow-up intervals for patients with regressing sacs.

Abstract
OBJECTIVE The aim of this study was to assess the risk of radiation-induced cancer development in patients that have undergone an infrarenal EVAR, stratifying the relative contributions of the procedure and the preoperative and postoperative CTAs. METHODS AND MATERIALS The organ-specific absorbed radiation doses from CTA and the EVAR procedure were estimated from the radiation exposures of 95 and 45 male patients, respectively. Lifetime attributable risk (LAR) cancer predictions were calculated for 14 different organs. Life expectancy was assumed from a previous cohort of patients undergoing infra-renal EVAR. RESULTS The calculated total excess cancer risk was 0.0046, ie, 1 out of 220 patients will develop a neoplasm after being exposed to the ionizing radiation from the preoperative CTA, the EVAR and annual CTA examinations for 15 years. The procedure and the preoperative CTA contributed with 38% of the total excess risk, while the rest was derived from the follow-up. If the entire CTA based follow-up would have been eliminated, an excess risk of 0.0018 (1/560) would remain. CONCLUSIONS 1 out of 219 patients who have undergone EVAR of an infra-renal AAA have a lifetime risk of developing cancer secondary to the radiation exposures related to the procedure and the CTAs used preoperatively and during follow-up. This risk derives mostly from the yearly postoperative CTAs, underlining the potential benefits of reducing or replacing their use. CLINICAL IMPACT A simulation-based estimation reinforced the potential deleterious effects of the radiation exposure for patients undergoing Endovascular Aneurysm Repair (EVAR) of Abdominal Aortic Aneurysms (AAA) and subsequently followed by yearly Computer Tomography Angiographies (CTAs). The risk could be as high as 1 out 219 patients developing a neoplasm after 15 years. The largest exposure derives from the follow-up CTAs and efforts to minimize their use as well as the intraoperative radiation are greatly needed. The simulation-based estimations done in this study reinforce potential deleterious effects of the radiation exposure for patients undergoing EVAR of AAA. Efforts should be done to minimize the intraoperative radiation and the number of CTAs used during follow-up.

Abstract
Thoracic and thoracoabdominal aortic aneurysms are more common in men. Yet, females often have worse outcomes, fewer interventions, and lower treatment rates. Females have also benefited less from the research and treatment of those diseases than men. Understanding sex- and sex-specific differences in thoracic and thoracoabdominal aortic aneurysms can improve care delivery, reduce disparities, and optimize outcomes for females with thoracic aortic aneurysms and thoracoabdominal aortic aneurysms. The authors reviewed the literature on the presentation and outcomes of thoracic and thoracoabdominal aortic aneurysms in females, discussing the existing gaps and future directions to address them.

Comparative outcomes of physician-modified fenestrated/branched endovascular aortic aneurysm repair in the setting of prior failed endovascular aneurysm repair. J Vasc Surg 2023; 78:1153-1161. [PMID: 37451371 DOI: 10.1016/j.jvs.2023.07.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2023] [Revised: 06/29/2023] [Accepted: 07/04/2023] [Indexed: 07/18/2023]
Abstract
OBJECTIVE Endovascular treatment of aortic aneurysms involving renal-mesenteric arteries, especially in the setting of prior failed endovascular aneurysm repair (EVAR) typically requires fenestrated/branched endovascular aneurysm repair (F/BEVAR) with a custom-made device (CMD). CMDs are limited to select centers, and physician-modified endografts are an alternative treatment platform. Currently, there is no data on the outcomes of physician-modified F/BEVAR (PM-F/BEVAR) in the setting of failed prior EVAR. The purpose of this study was to evaluate the use of PM-F/BEVAR in patients with prior failed EVAR. METHODS A prospective database of consecutive patients treated at a single center with PM-F/BEVAR between March 2021 and November 2022 was retrospectively reviewed. The cohort was stratified by presence of a failed EVAR (type Ia endoleak or aneurysm development proximal to a prior EVAR) prior to PM-F/BEVAR. Demographics, operative details, and postoperative complications were compared between the groups using univariate analysis. One-year survival and freedom from reintervention were compared using the Kaplan-Meier method. RESULTS A total of 103 patients underwent PM-F/BEVAR during the study period; 27 (26%) were in the setting of prior EVAR. Patients with prior failed EVAR had similar age (75.2 ± 7.7 vs 71.5 ± 8.8 years; P = .058), male gender (n = 24 ; 89% vs n = 57 ; 75%; P = .130), and comorbid conditions except higher incidence of moderate-to-severe chronic obstructive pulmonary disease (n = 7 ; 26% vs n = 7 ; 9%; P = .047). Overall, aneurysm diameter was 65.5 ± 13.9 mm with aneurysms categorized as juxta-/pararenal in 43% and thoracoabdominal in 57%, with no differences between the groups. Twelve patients (14%) presented with symptomatic/ruptured aneurysms. The average number of target arteries incorporated per patient was 3.8. Four different aortic devices were modified with a greater proportion of Terumo TREO devices used in the failed EVAR group (P = .03). There was no difference in procedure time, radiation dose, or iodinated contrast use between groups. Overall technical success was 99%. Rates of 30-day mortality (n = 0 ; 0% vs n = 3 ; 4%; P = .565) and major adverse events (n = 6 ; 22% vs n = 16 ; 21%; P = 1.0) were similar between groups. For the overall cohort, rates of type 1 or 3 endoleak, branch vessel stenosis/occlusion, and reintervention were 2%, 1%, and 8%, respectively, with no difference between groups. One-year survival (failed EVAR 94% vs no EVAR 82%; P = .756) was similar between groups. CONCLUSIONS PM-F/BEVAR is a safe and effective treatment for patients with aneurysms involving the renal-mesenteric arteries in the setting of prior failed EVAR where additional technical challenges may be present. Additional follow-up is warranted to demonstrate long-term efficacy, but early results are encouraging and similar to those using CMDs.

Abstract
AIM The "2022 ACC/AHA Guideline for the Diagnosis and Management of Aortic Disease" provides recommendations to guide clinicians in the diagnosis, genetic evaluation and family screening, medical therapy, endovascular and surgical treatment, and long-term surveillance of patients with aortic disease across its multiple clinical presentation subsets (ie, asymptomatic, stable symptomatic, and acute aortic syndromes). METHODS A comprehensive literature search was conducted from January 2021 to April 2021, encompassing studies, reviews, and other evidence conducted on human subjects that were published in English from PubMed, EMBASE, the Cochrane Library, CINHL Complete, and other selected databases relevant to this guideline. Additional relevant studies, published through June 2022 during the guideline writing process, were also considered by the writing committee, where appropriate. STRUCTURE Recommendations from previously published AHA/ACC guidelines on thoracic aortic disease, peripheral artery disease, and bicuspid aortic valve disease have been updated with new evidence to guide clinicians. In addition, new recommendations addressing comprehensive care for patients with aortic disease have been developed. There is added emphasis on the role of shared decision making, especially in the management of patients with aortic disease both before and during pregnancy. The is also an increased emphasis on the importance of institutional interventional volume and multidisciplinary aortic team expertise in the care of patients with aortic disease.

Abstract
BACKGROUND Practice guidelines recommend elective repair for abdominal aortic aneurysms (AAAs) ≥ 5.5 cm in men and ≥ 5 cm in women to prevent rupture; however, some rupture at smaller diameters. We identify risk factors for rupture AAA (rAAA) below this threshold and compare outcomes following rAAA repair above/below size criteria. METHODS The Vascular Quality Initiative (2013-2019) was queried for patients undergoing repair for rAAA and stratified based on diameter into small and large cohorts [Small: < 5.5 cm (men), < 5.0 cm (women)]. Univariate analysis was performed, and Kaplan-Meier analysis compared overall survival, aneurysm-related mortality, and reintervention at 12 months. RESULTS Five thousand one hundred sixty two rAAA were identified. Small rAAA patients [n = 588] were more likely to have hypertension (81.3% vs. 77.0%, P < 0.02), diabetes (18.2% vs. 14.9%, P < 0.04), and end-stage renal disease (2.9% vs. 0.9%, P < 0.01) and be on optimal medical therapy (32.1% vs. 26.8%, P < 0.01). Women were more likely to rupture at smaller diameters compared to men (P < 0.01). Small rAAA patients were more likely to undergo endovascular aortic repair (EVAR) (70.2% vs. 56.0%, P < 0.01) and had lower in-hospital mortality (17.7% vs. 27.7%, P < 0.01) and fewer perioperative complications across all categories. At 12 months, small rAAA patients had better overall survival, freedom from aneurysm-related mortality, and freedom from reintervention, largely driven by EVAR approach. CONCLUSIONS More than 11% of patients presenting with ruptured AAA were below the recommended size threshold for repair, and they tended to be younger, non-White, and have hypertension, diabetes, and/or renal failure. Patients with small rAAA experienced lower in-hospital morbidity and mortality and improved 1-year survival, and EVAR was associated with better outcomes than open repair. However, women more frequently rupture at smaller diameters compared to men. Given contemporary elective outcomes for women, a randomized controlled trial for EVAR versus surveillance at a sex-specific size threshold is needed.

Left Renal Vein Division during Open Surgical Repair for Abdominal Aortic Aneurysm May Cause Long-Term Kidney Remodeling. Ann Vasc Surg 2023; 96:155-165.

Abstract
BACKGROUND Left renal vein division (LRVD) is a maneuver performed during open surgical repair for abdominal aortic aneurysms. Even so, the long-term effects of LRVD on renal remodeling are unknown. Therefore, we hypothesized that interrupting the venous return of the left renal vein might cause renal congestion and fibrotic remodeling of the left kidney. METHODS We used a murine left renal vein ligation model with 8-week-old to 12-week-old wild-type male mice. Bilateral kidneys and blood samples were harvested postoperatively on days 1, 3, 7, and 14. We assessed the renal function and the pathohistological changes in the left kidneys. In addition, we retrospectively analyzed 174 patients with open surgical repairs between 2006 and 2015 to assess the influence of LRVD on clinical data. RESULTS Temporary renal decline with left kidney swelling occurred in a murine left renal vein ligation model. In the pathohistological assessment of the left kidney, macrophage accumulation, necrotic atrophy, and renal fibrosis were observed. In addition, Myofibroblast-like macrophage, which is involved in renal fibrosis, was observed in the left kidney. We also noted that LRVD was associated with temporary renal decline and left kidney swelling. LRVD did not, however, impair renal function in long-term observation. Additionally, the relative cortical thickness of the left kidney in the LRVD group was significantly lower than that of the right kidney. These findings indicated that LRVD was associated with left kidney remodeling. CONCLUSIONS Venous return interruption of the left renal vein is associated with left kidney remodeling. Furthermore, interruption in the venous return of the left renal vein does not correlate with chronic renal failure. Therefore, we suggest careful follow-up of renal function after LRVD.

Abstract
PURPOSE Hostile proximal neck anatomy has historically been associated with worse outcomes for endovascular aortic aneurysm repair (EVAR) of abdominal aortic aneurysms (AAA). We investigated the impact of proximal neck anatomy on the outcomes following EVAR with the Ovation abdominal stent graft (Endologix, Irving, Calif). METHODS We used prospectively collected data from the Effectiveness of Custom Seal with Ovation: Review of the Evidence database, compromised of pooled data from 6 clinical trials and the European Post-Market Registry of patients undergoing elective infrarenal EVAR (2009-2017). We investigated the impact of short neck length (<10 mm), wide neck diameter (≥28 mm), reverse taper shape (>10%), and neck angulation (>45°) on the outcomes. The primary outcome was type IA endoleak. Secondary outcomes included any type I/III endoleak, sac expansion, aneurysm-related reinterventions, and all-cause and aneurysm-related mortality, and a combined endpoint of type IA endoleak, graft migration, AAA-related reintervention, conversion, and aneurysm rupture. We used Kaplan-Meier analysis and Cox proportional hazards models to estimate the 30 day and 5 year rates and assess univariate and risk-adjusted differences. RESULTS Of the 1020 patients, 60 patients had a short neck, 113 had a wide neck diameter, 279 were reverse taper shaped, and 99 had neck angulation >45°. Wide proximal neck was associated with higher 5 year type IA endoleak estimates compared with favorable neck anatomy (7.1% vs 4.3%; p=0.02). No association with 5 year type IA endoleak was found for short neck length (1.7% vs 4.3%; p=0.52), reverse taper shape (3.2% vs 4.3%; p=0.99), or neck angulation (6.1% vs 4.3%; p=0.13). A wide neck diameter compared with favorable anatomy was also associated with higher 5 year estimates of graft migration (3.8% vs 0.4%; p=0.03) and the combined neck-related adverse outcome endpoint (16% vs 9.5%; p=0.002). The estimates of aneurysm sac expansion, rupture, and overall and aneurysm-related mortality were similar between the hostile proximal neck anatomy cohorts and favorable anatomy. CONCLUSION Wide proximal neck is associated with higher 5 year type IA endoleak rates for patients treated with the Ovation stent graft. However, short neck length, reverse taper shape, and neck angulation are not associated with higher 5 year type IA endoleak rates. CLINICAL IMPACT Hostile proximal neck anatomy has historically been associated with worse outcomes for endovascular aortic aneurysm repair of abdominal aortic aneurysms. The Ovation stent graft platform uses a different proximal sealing method using a polymer inflatable ring, aiming to improve sealing between the graft and aortic wall. This study demonstrated that short, angulated, and reverse taper-shaped neck anatomy did not result in increased type IA endoleak estimates in patients treated with the Ovation stent graft platform. Potentially, the different sealing mechanisms played a role in mitigating the historically worse outcomes in patients with short, angulated, and reverse taper-shaped neck anatomy.

J Vasc Surg 2023; 78:89-95.e2. [PMID: 36893948 DOI: 10.1016/j.jvs.2023.02.017] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Revised: 02/21/2023] [Accepted: 02/25/2023] [Indexed: 03/09/2023]
Abstract
BACKGROUND Previous studies have identified groups of patients with abdominal aortic aneurysm (AAA) that fall outside of currently accepted screening guidelines. Population-based studies have found AAA screening would be cost-effective at a prevalence of 0.5% to 1.0%. The goal of this study was to determine the prevalence of AAA in patients that fall outside of the current screening guidelines. In addition, we analyzed outcomes of the groups with a prevalence of greater than 1%. METHODS Using the TriNetX Analytics Network, several patient cohorts were abstracted with a diagnosis of ruptured or unruptured AAA based on previously identified groups with a potentially high risk for AAA that fall outside of currently accepted screening guidelines. Groups were also stratified by sex. For groups found to have a prevalence of greater than 1%, the unruptured patients were further analyzed for long-term rates of rupture and included male ever-smokers aged 45 to 65, male never-smokers aged 65 to 75, male never-smokers aged greater than 75, and female ever-smokers aged 65 or greater. Long-term mortality, stroke, and myocardial infarction rates were compared in patients with treated and untreated AAA after propensity score matching. RESULTS We identified 148,279 patients across the four groups with a prevalence of AAA of greater than 1% with female ever-smokers aged 65 or older being the most prevalent (2.73%). In each of the four groups, the rate of AAA rupture increased every 5 years and all had rupture rates of greater than 1% at 10 years. Meanwhile, controls for each of these four subgroups without a previous AAA diagnosis had rupture rates between 0.090% and 0.013% at 10 years. Those who underwent repair of their AAA had decreased incidence of mortality, stroke, and myocardial infarction. Specifically, male ever-smokers aged 45 to 64 had a significant difference in incidence of mortality and myocardial infarction at 5 years and stroke at 1 and 5 years. CONCLUSIONS Our analysis suggests male ever-smokers aged 45 to 65, male never-smokers aged 65 to 75, male never-smokers aged greater than 75, and female ever-smokers aged 65 or greater have a more than 1% prevalence of AAA and, therefore, may benefit from screening. Outcomes were significantly worse compared with well-matched controls in these groups.

Abstract
BACKGROUND Concerns have been raised about the long-term performance of aortic stent grafts for the treatment of abdominal aortic aneurysms, in particular, unibody stent grafts (eg, Endologix AFX AAA stent grafts). Only limited data sets are available to evaluate the long-term risks related to these devices. The SAFE-AAA Study (Comparison of Unibody and Non-Unibody Endografts for Abdominal Aortic Aneurysm Repair in Medicare Beneficiaries Study) was designed with the Food and Drug Administration to provide a longitudinal assessment of the safety of unibody aortic stent grafts among Medicare beneficiaries. METHODS The SAFE-AAA Study was a prespecified, retrospective cohort study evaluating whether unibody aortic stent grafts are noninferior to non-unibody aortic stent grafts with respect to the composite primary outcome of aortic reintervention, rupture, and mortality. Procedures were evaluated from August 1, 2011, through December 31, 2017. The primary end point was evaluated through December 31, 2019. Inverse probability weighting was used to account for imbalances in observed characteristics. Sensitivity analyses were used to evaluate the effect of unmeasured confounding, including assessment of the falsification end points heart failure, stroke, and pneumonia. A prespecified subgroup included patients treated from February 22, 2016, through December 31, 2017, corresponding to the market release of the most contemporary unibody aortic stent grafts (Endologix AFX2 AAA stent graft). RESULTS Of 87 163 patients who underwent aortic stent grafting at 2146 US hospitals, 11 903 (13.7%) received a unibody device. The average age of the total cohort was 77.0±6.7 years, 21.1% were female, 93.5% were White, 90.8% had hypertension, and 35.8% used tobacco. The primary end point occurred in 73.4% of unibody device-treated patients versus 65.0% of non-unibody device-treated patients (hazard ratio, 1.19 [95% CI, 1.15-1.22]; noninferior P value of 1.00; median follow-up, 3.4 years). Falsification end points were negligibly different between groups. In the subgroup treated with contemporary unibody aortic stent grafts, the cumulative incidence of the primary end point occurred in 37.5% of unibody device-treated patients and 32.7% of non-unibody device-treated patients (hazard ratio, 1.06 [95% CI, 0.98-1.14]). CONCLUSIONS In the SAFE-AAA Study, unibody aortic stent grafts failed to meet noninferiority compared with non-unibody aortic stent grafts with respect to aortic reintervention, rupture, and mortality. These data support the urgency of instituting a prospective longitudinal surveillance program for monitoring safety events related to aortic stent grafts.

Locoregional anesthesia is associated with reduced hospital stay and need for intensive care unit care of elective endovascular aneurysm repair patients in the Vascular Quality Initiative. J Vasc Surg 2023; 77:1061-1069. [PMID: 36400363 DOI: 10.1016/j.jvs.2022.11.043] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2022] [Revised: 11/08/2022] [Accepted: 11/09/2022] [Indexed: 11/17/2022]
Abstract
OBJECTIVE It has been shown local or regional anesthetic techniques are a feasible alternative to general anesthesia for endovascular aortic aneurysm repair (EVAR). However, studies to date have shown controversial findings with respect to the benefit of locoregional anesthesia (LR) in the elective setting. The objective of this study is to compare postoperative outcomes between LR and general anesthesia (GA) in the setting of elective EVAR, using a large, multicenter database. METHODS Using the Society for Vascular Surgery Vascular Quality Initiative database, we retrospectively analyzed all patients who underwent elective EVAR from August 2003 to June 2021. Patients were grouped by anesthetic type based on the level of consciousness afforded by the anesthetic: local or regional anesthesia (LR) vs GA. Primary outcomes were total postoperative hospital length-of-stay (LOS) and intensive care unit (ICU) LOS. Propensity score matching was used for risk adjustment and to analyze the primary outcomes with confirmatory analysis using logistic or linear regression, as appropriate, in single and multilevel models. Secondary outcomes were 30-day mortality, 1-year mortality, postoperative outcomes, operative time, fluoroscopy time, and reoperation rate. These were analyzed following propensity score matching as well as using logistic regression and Cox proportional hazard regression in single and multilevel models, as appropriate. RESULTS A total of 50,809 patients underwent elective EVAR from 2003 to 2021. Of these, 4302 repairs used LR (8.5%) and 46,507 (91.5%) were performed under GA. After employing propensity score matching, two groups of 3027 patients were produced. These showed no significant difference in 30-day mortality (odds ratio, 1.22; P = .53), 1-year mortality (hazard ratio, 1.06; P = .62), or any postoperative outcomes. LR was found to be significantly associated with shorter hospital stays (≤2 days) (12.5% vs 14.8%; P = .01), decreased ICU utilization (19.3% vs 30.6%; P < .001), decreased operative time (110.8 vs 117.3 minutes; P < .001), decreased fluoroscopy time (21.0 vs 22.7 minutes; P < .001), and a slight reduction in reoperation rate (1.2% vs 1.9%; P = .02), which all remained significant following single-level and multilevel multivariate analyses accounting for hospital and physician random effects. CONCLUSIONS These data suggest that LR anesthesia is safe and may offer advantages in reducing resource utilization for patients undergoing elective EVAR, primarily based on associations with reduced ICU care and reduced hospital stay. Given these findings, LR may prove an advantageous technique in appropriately selected patient populations.

Abstract
PURPOSE To report outcomes of endovascular repair (EVAR) of infrarenal abdominal aortic aneurysms (AAAs) with currently-available endografts and identify predictors of technical/clinical failure. MATERIALS AND METHODS Patients undergoing EVAR between 2012 and 2020 were prospectively collected and retrospectively analyzed. Technical success (TS: no type I-III endoleaks, renal/hypogastric arteries loss, iliac leg occlusion, conversion to open repair and mortality within 24 postoperative hour), proximal neck-related TS (nr-TS: no proximal type I endoleaks, unplanned renal arteries coverage), and 30-day mortality were assessed as early outcomes. Proximal type I endoleak (ELIa), survival and freedom from reinterventions (FFRs) were assessed during follow-up. Uni/multivariate analysis and Cox-regression were used to identified factors associated with early and follow-up outcomes; FFR and survival were assessed by Kaplan-Meier analysis. RESULTS A total of 710 were included. Technical success and nr-TS were 692 (98%) and 700 (99%), respectively. The presence of ≥2 hostile anatomical infrarenal neck characteristics was associated with technical failure (odds ratio [OR]: 2.4; 95% confidence interval [CI]: 1.3-4.1; p: 0.007). Infrarenal neck angle >90° (OR: 2.88; 95% CI: 9.6-50.3; p: 0.004), barrel shape (OR: 2.33; 95% CI: 11.1-100.3; p: 0.02) or presence of ≥2 hostile anatomical infrarenal neck characteristics (OR: 2.16; 95% CI: 2.5-5.3; p: 0.03) were independent risk factors for neck-related technical failures. Six (0.8%) patients died within 30 postoperative days. Chronic obstructive pulmonary disease (OR: 16; 95% CI: 1.1-218.3; p: 0.04) and urgent repair (OR: 15; 95% CI: 1.8-119.6; p: 0.01) were independent risk factors for 30-day mortality. The mean follow-up was 53±13 months. There were 12 (1.7%) ELIa during follow-up. Infrarenal neck length <15 mm (hazard ratio [HR]: 2.8; 95% CI: 1.9-9.6; p: 0.005), diameter >28 mm (HR: 2.7; 95% CI: 1.6-9.5; p: 0.006), angle ≥90° (HR: 2.7; 95% CI: 8.3-50.1; p: 0.007), and persistent type II endoleak (HR: 2.9; 95% CI: 1.6-10.1; p: 0.004) were independent risk factors for ELIa. Freedom from reintervention was 91% at 5 years. The ELIa was an independent risk factor for reinterventions during follow-up (HR: 29.5; 95% CI: 1.4-1.6; p<0.001). Survival was 74% at 5 years with 2 cases (0.3%) of late aortic-related mortality. Peripheral arterial occlusive disease (HR: 1.9; 95% CI: 1.4-3.65; p: 0.03), aneurysm diameter ≥65 mm (HR: 2.2; 95% CI: 1.4-3.26; p<0.001), and infrarenal neck length <15 mm (HR: 1.7; 95% CI: 1.2-2.35; p: 0.04) were independent risk factors for mortality during follow-up. CONCLUSION Endovascular repair with currently-available endografts has high TS and low 30-day mortality. Survival and FFRs were satisfactory at mid-term. Pre/postoperative risk factors for technical and clinical failure were identified and they should be considered in EVAR indication and postoperative management to reduce complications and improve mid-term outcome. CLINICAL IMPACT Pre and postoperative risk factors for technical and clinical EVAR failure can be identified and they should be considered in EVAR indication and postoperative management to reduce complications and improve mid-term outcome.

Mortality analysis of endovascular aneurysm sealing versus endovascular aneurysm repair. J Vasc Surg 2023; 77:731-740.e1. [PMID: 36651654 PMCID: PMC9974809 DOI: 10.1016/j.jvs.2022.10.030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2022] [Revised: 09/21/2022] [Accepted: 10/25/2022] [Indexed: 12/24/2022]
Abstract
BACKGROUND Endovascular aneurysm sealing (EVAS), using the Nellix endovascular aneurysm sealing system, has been associated with high reintervention and migration rates. However, prior reports have suggested that EVAS might be related to a lower all-cause mortality compared with endovascular aneurysm repair (EVAR). In the present study, we examined the 5-year all-cause mortality trends after EVAS and EVAR. METHODS We compared the 333 EVAS patients in the EVAS-1 Nellix U.S. investigational device exemption trial with 16,497 infrarenal EVAR controls from the Vascular Quality Initiative, treated between 2014 and 2016, after applying the exclusion criteria from the investigational device exemption trial (ie, hemodialysis, creatinine >2.0 mg/dL, rupture). As a secondary analysis, we stratified the patients by aneurysm diameter (<5.5 cm and ≥5.5 cm). We calculated propensity scores after adjusting for demographics, comorbidities, and anatomic characteristics and applied inverse probability weighting to compare the risk-adjusted long-term mortality using Kaplan-Meier and Cox regression analyses. RESULTS After weighting, the EVAS group had experienced similar 5-year mortality compared with the controls from the Vascular Quality Initiative (EVAS vs EVAR, 18% vs 14%; hazard ratio [HR], 1.1; 95% confidence interval [CI], 0.71-1.7; P = .70). The subgroup analysis demonstrated that for patients with an aneurysm diameter of <5.5 cm, EVAS was associated with higher 5-year mortality compared with EVAR (19% vs 11%; HR, 2.4; 95% CI, 1.7-4.7; P = .013). In patients with an aneurysm diameter of ≥5.5 cm, EVAS was associated with lower mortality within the first 2 years (2-year mortality: HR, 0.29; 95% CI, 0.13-0.62; P = .002). However, compared with EVAR, EVAS was associated with higher mortality between 2 and 5 years (HR, 1.9; 95% CI, 1.2-3.0; P = .005), with no mortality difference at 5 years (18% vs 17%; HR, 0.82; 95% CI, 0.4-1.4; P = .46). CONCLUSIONS Within the overall population, EVAS was associated with similar 5-year mortality compared with EVAR. EVAS was associated with higher mortality for those with small aneurysms (<5.5 cm). For those with larger aneurysms (≥5.5 cm), EVAS was initially associated with lower mortality within the first 2 years, although this advantage was lost thereafter, with higher mortality after 2 years. Future studies are required to evaluate the specific causes of death and to elucidate the potential beneficial mechanism behind sac obliteration that leads to this potential initial survival benefit. This could help guide the development of future grafts with better proximal fixation and sealing that also incorporate sac obliteration.

Abstract
BACKGROUND Abdominal aortic aneurysm (AAA) screening has contributed in the decrease of aneurysm related and all-cause mortality. The objective of our study is to present our experience from the only existing pilot AAA screening program in Greece. METHODS Men from both urban and rural areas in Central Greece, aged >60 years old without a previously known diagnosis of AAA were invited through the public primary health care units to participate to a screening program. Demographics, comorbidities, family history and anthropometric data were recorded. Aortic diameter values of >30 mm and common iliac artery (CIA) diameter values of >18 mm, were defined as aneurysmatic by ultrasound. RESULTS The screening program included 1256 individuals (1256/1814; response rate 69%). The incidence of AAA and CIA aneurysm was 2% (25/1256) and 2.3% (29/1256), respectively. Increased age (P<0.042), tobacco use (P<0.006) and its duration (P<0.008) were related to higher incidence of AAA, while diabetes mellitus to lower one (P<0.048). Multivariate analysis showed that AAA was associated to longer duration of smoking (1.05, CI: 0.02-6.6; P=0.01). Statin and antiplatelet therapy were administrated in 40% (10/25) and 44% (11/25), respectively of individuals with AAA. An additional analysis was provided between subjects with AD of 25-30 mm and AD <25 mm. In multivariate analysis, no factor was associated to AD of 25-30 mm. CONCLUSIONS The incidence of AAA and CIA aneurysm in Central Greece is 2% and 2.3%, respectively. Smoking duration was the strongest associated factor with AAA incidence. This provides to healthcare policy makers a strong valid point for the prevention strategies.

J Vasc Surg 2023; 77:28-36.e3. [PMID: 36070845 DOI: 10.1016/j.jvs.2022.08.035] [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: 06/06/2022] [Revised: 08/10/2022] [Accepted: 08/17/2022] [Indexed: 02/03/2023]
Abstract
OBJECTIVE The aim of this study was to compare midterm results of EndoAnchors in EndoSuture aneurysm repair (ESAR) versus fenestrated endovascular aneurysm repair (FEVAR) in short neck abdominal aortic aneurysm (AAA). METHODS All patients who underwent an ESAR procedure for a short neck AAA at our center between September 2017 and May 2020 were considered for analysis. To form the control group, preoperative computed tomography angiography of patients who underwent FEVAR for juxtarenal AAA between April 2012 and May 2020 were reviewed and patients who met short neck criteria selected. A propensity-matched score on neck length and neck diameter was calculated, resulting in 18 matched pairs. AAA shrinkage, type Ia endoleaks (EL), AAA-related reinterventions, and AAA-related deaths were compared. RESULTS The median AAA diameter was 54 mm (interquartile range [IQR], 52-61 mm) versus 58 mm (IQR, 53-63 mm) with a median neck length of 8 mm (IQR, 6-12 mm) vs 10 mm (IQR, 6-13 mm) in ESAR and FEVAR patients, respectively. Technical success was 100% in both groups. Procedural success was 94% in the ESAR group versus 100% in the FEVAR group. The median procedure duration was 138 mm (IQR, 113-182 mm) vs 240 mm (IQR, 199-293 mm) ( P < .001) and the median length of stay was 2 days (IQR, 2-3 days) vs 7 days (IQR, 6-7 days) (P < .001) in ESAR and FEVAR patients, respectively. No major hospital complications were observed in ESAR patients compared with two in FEVAR patients (11%) with one transient acute kidney injury and one transient paraplegia. The median follow-up was 23 months (IQR, 19-33 months) vs 36 months (IQR, 22-57 months) with 67% versus 61% AAA shrinkage in the ESAR and FEVAR groups, respectively (P = .73). No type Ia EL, proximal neck-related reinterventions, or AAA-related deaths were observed in either group. No AAA-related reintervention was observed in the ESAR group versus three reinterventions in the FEVAR group (P = .23). CONCLUSIONS ESAR seems to be a safe technique with no major postoperative complications or reinterventions observed during follow-up. It seems to offer similar midterm results as FEVAR in terms of type Ia EL, aneurysm shrinkage, and aneurysm-related mortality. ESAR seems to be a good off-the-shelf alternative to FEVAR in case of technical constraints.

Abstract
AIM The "2022 ACC/AHA Guideline for the Diagnosis and Management of Aortic Disease" provides recommendations to guide clinicians in the diagnosis, genetic evaluation and family screening, medical therapy, endovascular and surgical treatment, and long-term surveillance of patients with aortic disease across its multiple clinical presentation subsets (ie, asymptomatic, stable symptomatic, and acute aortic syndromes). METHODS A comprehensive literature search was conducted from January 2021 to April 2021, encompassing studies, reviews, and other evidence conducted on human subjects that were published in English from PubMed, EMBASE, the Cochrane Library, CINHL Complete, and other selected databases relevant to this guideline. Additional relevant studies, published through June 2022 during the guideline writing process, were also considered by the writing committee, where appropriate. Structure: Recommendations from previously published AHA/ACC guidelines on thoracic aortic disease, peripheral artery disease, and bicuspid aortic valve disease have been updated with new evidence to guide clinicians. In addition, new recommendations addressing comprehensive care for patients with aortic disease have been developed. There is added emphasis on the role of shared decision making, especially in the management of patients with aortic disease both before and during pregnancy. The is also an increased emphasis on the importance of institutional interventional volume and multidisciplinary aortic team expertise in the care of patients with aortic disease.

Disparities in 5-year outcomes and imaging surveillance following elective endovascular repair of abdominal aortic aneurysm by sex, race, and ethnicity. J Vasc Surg 2022; 76:1205-1215.e4. [PMID: 35569727 PMCID: PMC9613484 DOI: 10.1016/j.jvs.2022.03.886] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2022] [Accepted: 03/29/2022] [Indexed: 11/17/2022]
Abstract
OBJECTIVES Sex, racial, and ethnic disparities in postoperative outcomes following abdominal aortic aneurysm repair have been described, but differences in long-term outcomes are poorly understood. Our aim was to identify differences in 5-year outcomes and imaging surveillance after elective endovascular aortic aneurysm repair (EVAR) by sex, race, and ethnicity and to explore potential mechanisms underlying these differences. METHODS We identified patients undergoing elective EVAR in the Vascular Quality Initiative from 2003 to 2017 with linkage to Medicare claims through 2018 for long-term outcomes. Our primary outcome was 5-year aneurysm rupture. Secondary outcomes were 5-year reintervention and mortality and 2-year loss-to-imaging follow-up (defined as no aortic imaging from 6 to 24 months after EVAR). We used Kaplan-Meier and Cox regression analyses to evaluate these outcomes by sex/race/ethnicity and constructed multivariable models to explore potential contributing factors. RESULTS Among 16,040 patients, 11,764 (73%) were White males, 2891 (18%) were White females, 417 (2.6%) were Black males, 175 (1.1%) were Black females, 141 (0.9%) were Asian males, 34 (0.2%) were Asian females, 277 (1.7%) were Hispanic males, and 60 (0.4%) were Hispanic females. At 5 years, rupture rates were highest in Black females at 6.4% and lowest in white males at 2.3%. Compared with White males, rupture rates were higher in White females (hazard ratio [HR], 1.5; 95% confidence interval [CI], 1.1-2.0), Black females (HR, 2.5; 95% CI, 1.0-6.0), and Asian females (HR, 5.2; 95% CI, 1.3-21). White females also had higher mortality (HR, 1.2; 95% CI, 1.2-1.3) and loss-to-imaging-follow-up (HR, 1.2; 95% CI, 1.1-1.3), whereas Black females had higher mortality (HR, 1.4; 95% CI, 1.1-1.8) and reintervention (HR, 2.0; 95% CI, 1.4-2.8). Among other groups, Black males had higher reintervention (HR, 1.4; 95% CI, 1.0-1.8), and both Black and Hispanic males had higher loss-to-imaging-follow-up (Black: HR, 1.4; 95% CI, 1.1-1.7; Hispanic: HR, 1.3; 95% CI, 1.0-1.8). In adjusted analyses, White, Black, and Asian females remained at significantly higher risk for 5-year rupture after accounting for procedure year, clinical and anatomic characteristics, surgeon and hospital volume, and loss-to-imaging follow-up. CONCLUSIONS Compared with White male patients, Black females had higher 5-year aneurysm rupture, reintervention, and mortality after elective EVAR, whereas White females had higher rupture, mortality and loss-to-imaging-follow-up. Asian females also had higher rupture, and Black males had higher reintervention and loss-to-imaging-follow-up. These populations may benefit from improved preoperative counseling and clinical outreach after EVAR. A larger-scale investigation of current practice patterns and their impact on sex, racial, and ethnic disparities in late outcomes after EVAR is needed to identify tangible targets for improvement.

Association between neighborhood deprivation and presenting with a ruptured abdominal aortic aneurysm before screening age. J Vasc Surg 2022; 76:932-941.e2. [PMID: 35314299 PMCID: PMC9482667 DOI: 10.1016/j.jvs.2022.03.009] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2021] [Accepted: 03/04/2022] [Indexed: 10/18/2022]
Abstract
OBJECTIVE Recent data indicate social determinants of health (SDOH) have a great impact on prevention and treatment outcomes across a broad variety of disease states, especially cardiovascular diseases. The area deprivation index (ADI) is a validated measure of neighborhood level disadvantage capturing key social determinate factors. Abdominal aortic aneurysm rupture (rAAA) is highly morbid, but also preventable through evidence-based screening. However, the association between rAAA and SDOH is poorly characterized. Our objective is to study the association of SDOH with rAAA and screening age. METHODS This retrospective study included patients who underwent operative repair of a rAAA at a multihospital healthcare system (2003-2019). Deprivation was measured by the ADI (scale 1-100), grouped into quintiles for simplicity, with higher quintiles indicating greater deprivation. Patients with the highest quintile ADI (89-100) were categorized as the most deprived. We investigated the association between neighborhood deprivation with the odds of (i) undergoing repair for rAAA before screening age 65 and (ii) undergoing endovascular aortic repair (EVAR) using logistic regression, sequentially modeling nonmodifiable then both nonmodifiable and modifiable confounding variables. RESULTS There were 632 patients who met the inclusion criteria (aged 74.2 ± 9.4 years; 174 women [27.6%]; 564 White [89.2%]; ADI 66.8 ± 22.3). Those from the most deprived neighborhoods (n = 118) were younger (71.7 ± 10.0 years vs 74.8 ± 9.2 years; P = .002), more likely to be female (36% vs 26%; P = .031), more likely to be Black (5.9% vs 0.4%; P = .007), and fewer underwent EVAR (28% vs 39.5%; P = .020) compared with those from other neighborhoods. On sequential modeling, residing in the most deprived neighborhoods was associated with undergoing rAAA repair before age 65 after adjusting for nonmodifiable factors (odds ratio [OR], 2.02; 95% confidence interval [CI], 1.39-2.95; P < .001), and nonmodifiable as well as modifiable factors (OR, 2.22; 95% CI, 1.56-3.16; P < .001). Those in the most deprived neighborhoods had a lower odds of undergoing EVAR compared with open repair after adjusting for nonmodifiable factors (OR, 0.64; 95% CI, 0.41-0.98; P = .042), and nonmodifiable as well as modifiable factors (OR, 0.61; 95% CI, 0.37-0.99; P = .047). CONCLUSIONS Among patients who underwent rAAA, residing in the most deprived neighborhoods was associated with greater adjusted odds of presenting under age 65 and undergoing an open repair. These neighborhoods represent tangible geographic targets that may benefit from a younger screening age, enhanced education, and access to care. These findings stress the importance of developing strategies for early prevention and diagnosis of cardiovascular diseases among patients with disadvantageous SDOH.

Center Volume and Failure to Rescue after Open or Endovascular Repair of Ruptured Abdominal Aortic Aneurysms. J Vasc Surg 2022; 76:1565-1576.e4. [PMID: 35872329 DOI: 10.1016/j.jvs.2022.05.022] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2021] [Revised: 04/26/2022] [Accepted: 05/05/2022] [Indexed: 11/20/2022]
Abstract
BACKGROUND The correlation between center volume and elective abdominal aortic aneurysm(AAA) repair outcomes is well established; however, these effects for either endovascular(EVAR) or open(OAR) repair of ruptured AAA(rAAA) remains unclear. Notably, the capacity to either avert or manage complications associated with postoperative mortality is an important cause of outcome disparities following elective procedures; however, there is a paucity of data surrounding non-elective presentations. Therefore, the purpose of this analysis was to describe the association between annual center volume, complications, and failure to rescue(FtR) after EVAR and OAR of rAAA. METHODS All consecutive endovascular and open rAAA repairs from 2010-2020 in the Vascular Quality Initiative were examined. Annual center volume(procedures/year per center) was grouped into quartiles: EVAR-Q1[<14](3.4%), Q2[14-23](12.8%), Q3[24-37](24.7%), Q4[>38](59.1%); OAR-Q1[<3](5.4%), Q2[4-6](12.8%), Q3[7-10](22.7%), Q4[>10](59.1%). The primary end-point was FtR, defined as in-hospital death after experiencing one of six major complications(cardiac, renal, respiratory, stroke, bleeding, colonic ischemia). Risk-adjusted analyses for inter-group comparisons was completed using multivariable logistic regression. RESULTS The unadjusted in-hospital death rate was 16.5% and 28.9% for EVAR and OAR, respectively. Complications occurred in 45% of EVAR(n=1,439/3,188) and 70% of OAR(n=1,366/1,961) patients with corresponding FtR rates of 14%(EVAR) and 26%(OAR). For OAR, Q4-centers had a 43% lower FtR risk(OR 0.57, 95%CI 0.4-0.9;p=.017) compared to Q1 centers. Centers performing >5 OARs/year had a 43% lower risk(OR 0.57, 95%CI 0.4-0.7;p<.001) of FtR and this decreased 4% for each additional 5 procedures performed annually(95%CI .93-.991;p=.013). However, there was no significant relationship between center volume and FtR after EVAR. The risk of FtR was strongly associated with a greater number of complications for both procedures(OR multiplied by 6.5 for EVAR and 1.5 for OAR for each additional complication;p<.0001). Among OAR patients with a single recorded complication, return to the operating room for bleeding had highest risk of in-hospital mortality(OR 4.1, 95%CI 1.1-4.8;p=.034), while no specific type of complication increased FtR risk after EVAR. CONCLUSIONS FtR occurs commonly after EVAR and OAR of rAAA within VQI centers. Importantly, increasing center volume was associated with reduced FtR risk after OAR but not EVAR. Complication pattern and frequency predicted FTR after either repair strategy. For stable patients, especially those deemed anatomically ineligible for EVAR, these findings emphasize the need to improve coordination of regional referral networks that centralize rAAAs to high-volume centers. Moreover, hospitals that treat rAAA should invest resources that develop protocols targeting specific complications to mitigate risk of preventable postoperative death.

Exploring the Effect and Mechanism of Si-Miao-Yong-An Decoction on Abdominal Aortic Aneurysm Based on Mice Experiment and Bioinformatics Analysis. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:4766987.

Abstract
Background Abdominal aortic aneurysm (AAA) is a fatal disease characterized by high morbidity and mortality in old population. Globally, effective drugs for AAA are still limited. Si-Miao-Yong-An decoction (SMYAD), a traditional Chinese medicine (TCM) formula with a high medical value, was reported to be successfully used in an old AAA patient. Thus, we reason that SMYAD may serve as a potential anti-AAA regime. Objective The exact effects and detailed mechanisms of SMYAD on AAA were explored by using the experimental study and bioinformatics analysis. Methods Firstly, C57BL/6N mice induced by Bap and Ang II were utilized to reproduce the AAA model, and the effects of SMYAD were systematically assessed according to histology, immunohistochemistry, and enzyme-linked immunosorbent assay (ELISA). Then, network pharmacology was applied to identify the biological processes, pathways, and hub targets of SMYAD against AAA; moreover, molecular docking was utilized to identify the binding ability and action targets. Results In an animal experiment, SMYAD was found to effectively alleviate the degree of pathological expansion of abdominal aorta and reduce the incidence of Bap/Ang II-induced AAA, along with reducing the damage to elastic lamella, attenuating infiltration of macrophage, and lowering the circulating IL-6 level corresponding to the animal study, and network pharmacology revealed the detailed mechanisms of SMYAD on AAA that were related to pathways of inflammatory response, defense response, apoptotic, cell migration and adhesion, and reactive oxygen species metabolic process. Then, seven targets, IL-6, TNF, HSP90AA1, RELA, PTGS2, ESR1, and MMP9, were identified as hub targets of SMYAD against AAA. Furthermore, molecular docking verification revealed that the active compounds of SMYAD had good binding ability and clear binding site with core targets related to AAA formation. Conclusion SMYAD can suppress AAA development through multicompound, multitarget, and multipathway, which provides a research direction for further study.

Trends in annual open abdominal aortic surgical volumes for vascular trainees compared to annual national volumes in the endovascular era. J Vasc Surg 2022; 76:1079-1086. [PMID: 35598821 DOI: 10.1016/j.jvs.2022.03.887] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2022] [Accepted: 03/30/2022] [Indexed: 10/18/2022]
Abstract
OBJECTIVE Prior analysis predicted a shortfall in open abdominal aortic repair (OAR) experience for vascular trainees resulting from the rapid adoption of and increased anatomic suitability of endovascular aortic repair (EVAR) technology. We explored how EVAR has transformed contemporary open aortic surgical education for vascular trainees. METHODS We examined ACGME case volumes of open abdominal aortic aneurysm (AAA) repair and reconstruction for aorto-iliac occlusive disease (AIOD) via aorto-iliac/femoral bypass (AFB) from integrated vascular surgery residents (VSR) and fellows (VSF) graduating 2006-2017 and compared them to national estimates of total OAR (open AAA repair + AFB) in the Agency for Healthcare Research and Quality National Inpatient Sample based on ICD-9 and ICD-10 procedural codes. Changes over time were assessed using Chi-square test, Student's t-test, and linear regression. RESULTS During the twelve-year study period, the national annual total OAR and open AAA repair estimates decreased: total OAR by 72.5% (2006: estimate (standard error) 24,255 (1185) vs. 2017: 6,690 (274); p<0.001) and open AAA repair by 84.7% (2006: 18,619 (924) vs. 2017: 2,850 (168); p<0.001); AFB estimates decreased by 33.0% (p<0.001). The percentage of total OAR, open AAA repair, and AFB performed at teaching hospitals significantly increased from ∼55 to 80% (all p<0.001). There was a 40.9% decrease in open AAA repairs logged by graduating VSF (mean 18.6 vs. 11) but only a 6.9% decrease in total OAR cases (mean 27.6 vs. 25.7) due to increasing AFB volumes (mean 9.0 vs. 14.7). VSR graduates consistently logged an average of ∼10 open AAA repairs and there was a 31.0% increase in total OAR (mean 23.2 vs. 30.4), again secondary to rising AFB volumes (mean 11.4 vs 17.5). Although there was an absolute decrease in open aortic experience for VSF, the rate of decline for total OAR case volumes was not significantly different after VSR programs were established (p=0.40). CONCLUSIONS As incidence decreases nationally, OAR is shifting towards teaching hospitals. While open AAA procedures for trainees are declining due to EVAR, open aortic reconstruction for AIOD is rising and plays an important role in ensuring that vascular trainees continue to have satisfactory OAR experience sufficient for meeting minimum graduation requirements. Strategies to maintain and maximize the education and experience from these cases should be top priority for vascular surgery program directors.

Long-term age-stratified survival following endovascular and open abdominal aortic aneurysm repair. J Vasc Surg 2022; 76:899-907.e3.

Abstract
OBJECTIVE The long-term survival differences between endovascular and open repair for abdominal aortic aneurysms and specifically the impact of age on these differences remain a topic of debate. Therefore, we compared the long-term mortality between endovascular and open abdominal aneurysm repair for patients of different ages. METHODS This was a retrospective cohort study of prospectively collected data from patients undergoing elective endovascular or open repair for infrarenal abdominal aortic aneurysms within the Vascular Quality Initiative multi-national clinical registry (2003-2021). The primary outcome was long-term all-cause mortality comparing endovascular and open repair for patients aged <65 years, between 65-79 years, and those aged ≥80. In addition, we investigated the interaction between repair modality and ten-year hazard of mortality for sex, aneurysm diameter, and several pre-operative comorbid conditions within each age category. To account for non-random assignment of treatment, we used propensity scores and inverse probability weighted Cox proportional hazard analysis. RESULTS We identified 48,074 patients undergoing elective infrarenal abdominal aneurysm repair (89% endovascular) within the study period, including 7,940 patients aged <65, 29,555 aged between 65-79, and 10,579 aged ≥80 years. EVAR was associated with a higher propensity score-adjusted long-term hazard of mortality compared to open repair in the cohort aged <65 years (hazard ratio [HR]: 1.39; 95% confidence interval [CI]: 1.04-1.86; P=.026). The mortality was similar in the age cohort between 65-79 (HR: 0.94; 95%CI: 0.79-1.10; P=.43), while EVAR was associated with a lower hazard of mortality in the cohort aged ≥80 years (HR: 0.63; 95%CI: 0.46-0.86; P=.004). In patients aged <65, the hazard of mortality was higher with endovascular compared with open repair in those with female sex (HR: 4.40; 95%CI: 1.75-11.0), an aneurysm diameter >65mm (HR: 2.19; 95%CI: 1.11-4.34), and absence of coronary artery disease (HR: 1.26; 95%CI: 0.83-1.91), congestive heart failure (HR: 1.41; 95%CI: 1.03-1.92), and renal dysfunction (HR: 1.46; 95%CI: 1.04-2.05). In the patient cohort aged ≥80, a lower hazard of mortality for endovascular vs. open repair was observed for male patients, or those with small aneurysms or certain comorbidities. CONCLUSIONS In a selected group of young patients with a substantial life expectancy, the long-term mortality is higher with endovascular compared to open repair for infrarenal abdominal aortic aneurysms. Long-term mortality with endovascular repair is similar in the middle cohort and lower in the elderly cohort compared to open repair.

Abstract
INTRODUCTION AND OBJECTIVES Despite the emergence of endovascular aneurysm repair (EVAR) as the most common approach to abdominal aortic aneurysm repair, open aneurysm repair (OAR) remains an important option. This study seeks to define the indications for OAR in the EVAR era and how these indications effect outcomes. METHODS A retrospective cohort study was performed of all OAR at a single institution from 2004 to 2019. Pre-operative computed tomography scans and operative records were assessed to determine the indication for OAR. These reasons were categorized into anatomical contraindications; systemic factors (connective tissue disorders, contraindication to contrast dye); and patient/surgeon preference (patients who were candidates for both EVAR and OAR). Perioperative and long-term outcomes were compared between the groups. RESULTS 370 patients were included in the analysis; 71.6% (265/370) had at least one anatomic contraindication to EVAR; 36% had two or more contraindications. The most common anatomic contraindications were short aortic neck length (51.6%), inadequate distal seal zone (19.2%), and inadequate access vessels (15.7%). The major perioperative complication rate was 18.1% and the 30-day mortality was 3.0%. No single anatomic factor was identified as a predictor of perioperative complications. Sixty-one patients (16.5%) had OAR based on patient/surgeon preference; these patients were younger; had lower incidences of coronary artery disease and chronic obstructive pulmonary disease; and they were less likely to require suprarenal cross clamping compared with patients who had anatomic and/or systemic contraindications to EVAR. The patient/surgeon preference group had a lower incidence of perioperative major complications (8.2% versus 20.1%, p=0.034), shorter length of stay (6 versus 8 days, p<0.001) and zero 30-day mortalities. The multivariable adjusted risk for 15-year mortality was lower for patient/surgeon preference patients (adjusted hazard ratio 0.44 [95% confidence interval 0.24-0.80], p=0.007) compared to those anatomic/systemic contraindications. CONCLUSIONS Within a population of patients who did not meet instruction for use (IFU) criteria for EVAR, no single anatomic contraindication was a marker for worse outcomes with OAR. Patients who were candidates for both aortic repair approaches but elected to have open surgical repair due to patient/surgeon preference have very low 30-day mortality and morbidity, and superior long-term survival rates compared with those patients who had OAR due to anatomic and/or systemic contraindications to EVAR.

Overview of screening eligibility in patients undergoing ruptured AAA repair from 2003 to 2019 in the Vascular Quality Initiative. J Vasc Surg 2022; 75:884-892.e1. [PMID: 34695553 PMCID: PMC8863628 DOI: 10.1016/j.jvs.2021.09.049] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2021] [Accepted: 09/21/2021] [Indexed: 12/18/2022]
Abstract
OBJECTIVE Although efforts such as the Screening Abdominal Aortic Aneurysms Very Efficiently (SAAAVE) Act have improved access to abdominal aortic aneurysm (AAA) screening, certain high-risk populations are currently excluded from the guidelines yet may benefit from screening. We therefore examined all patients who underwent repair of ruptured AAA (rAAA) to characterize those who are ineligible for screening under current guidelines and evaluate the potential impact of these restrictions on their disease. METHODS We identified patients undergoing rAAA repair in the Vascular Quality Initiative (VQI) database between 2003 and 2019. These patients were stratified by AAA screening eligibility according to the Centers for Medicare and Medicaid reimbursement guidelines. We then described baseline characteristics to identify high-risk features of these cohorts. Groups with disproportionate representation in the screening-ineligible cohort were identified as potential targets of screening expansion. Trends over time in screening eligibility and the proportion of AAA repairs performed for rAAA were also analyzed. RESULTS A total of 5340 patients underwent rAAA repair. The majority (66%) were screening-ineligible. When characterizing the screening-ineligible group by sex and risk factors (smoking history or family history of AAA), the largest contributors to screening ineligibility were males less than 65 years of age with a smoking history or family history of AAA (25%), males greater than 75 years of age with a smoking history (25%), and females older than 65 years of age with a smoking history (19%). In comparison with rAAAs prior to implementation of the SAAAVE act, the proportion of AAA repair performed for rupture among males undergoing AAA repair in the VQI decreased from 12% to 8% (P < .001), whereas in females, there was no change (P = .990). There was no statically significant difference in screening eligibility for either males (P = .762) or females (P = .335). CONCLUSIONS Most patients who underwent rAAA repair were ineligible for initial AAA screening or aged out of the screening window. Furthermore, rAAA rates and screening ineligibility have not improved as much as expected since the passage of the SAAAVE Act. Our data suggest that three high-risk populations may benefit from expansion of AAA screening guidelines: males with a smoking history or family history of AAA between ages 55 and 64 years, female smokers older than 65 years, and male smokers older than 75 years who are otherwise in good health. Increased efforts to screen these high-risk populations may increase elective AAA repair and minimize the morbidity and mortality associated with rAAAs.

Abstract
OBJECTIVES The US Preventive Services Task Force (USPSTF) recommends a 1-time screening for AAA with ultrasonography in men aged 65-75 who have ever smoked. Our objectives were to identify the AAA screening rates in a large academic health system and assess factors associated with receipt of screening. METHODS Data were extracted from electronic health record data from the Duke University Health System and the US Census Bureau. Index screening eligibility date was defined as the 65th birthdate for male patients with a history of smoking. Patients with an index screening eligibility date between 1/1/2016 and 12/31/2018 were included in the study population and followed through 12/31/2019. Screened patients were identified by procedure codes for ultrasonography, CT or MRI. RESULTS Among 6,682 eligible patients who turned 65 years old between 1/1/2016 and 12/31/2018 with at least 1 year of follow-up, only 463 (6.9%) received AAA screening during the study period. The odds of receiving AAA screening within 1 year of index eligibility were 27% lower for Black patients compared to whites [OR=0.73, 95% CI (0.58,0.93)]. Patients who visited a PCP or had hypertension had 75% and 41% greater odds of receiving screening, respectively [OR 1.75, 95% CI (1.36,2.25)] and [OR 1.41 95% CI (1.11,1.80)] compared with patients who did not. Among 4,580 men with 2 years of follow-up, AAA screening rate increased to 13.0%. Patients who visited a PCP had 64% greater odds of receiving screening within 2 years of index eligibility compared to those who did not [OR=1.64, 95% CI (1.30,2.06)]. CONCLUSION Screening for AAA per USPSTF guidelines is underutilized with evidence of a racial disparity. Although PCP visit is the most consistent predictor of screening, provider screening rates are low.

Abstract
Artificial intelligence (AI) is the next great advance informing medical science. Several disciplines, including vascular surgery, use AI-based decision-making tools to improve clinical performance. Although applied widely, AI functions best when confronted with voluminous, accurate data. Consistent, predictable analytic technique selection also challenges researchers. This article contextualizes AI analyses within evidence-based medicine, focusing on "big data" and health services research, as well as discussing opportunities to improve data collection and realize AI's promise.
