The association of ruptured abdominal aortic aneurysm diameter with mortality in the International Consortium of Vascular Registries. J Vasc Surg 2024; 79:748-754.e2. [PMID: 38013041 PMCID: PMC11144387 DOI: 10.1016/j.jvs.2023.11.033] [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: 07/19/2023] [Revised: 11/15/2023] [Accepted: 11/21/2023] [Indexed: 11/29/2023]
Abstract
BACKGROUND The mortality after ruptured abdominal aortic aneurysm (rAAA) repair is high, despite improvements in perioperative care, centralization of emergency vascular surgical services, and the introduction of endovascular aneurysm repair (EVAR). The diameter of intact AAA has been shown to be a predictor of short- and long-term survival. The aim of this study was to analyze the impact of AAA diameter on mortality for rAAA repair using contemporary data collected from the International Consortium of Vascular Registries and compare outcomes by sex and the type of repair patients received. METHODS Prospective registry data on repair of rAAA from seven countries were collected from 2010 to 2016. The primary outcome was perioperative mortality after EVAR and open surgical repair (OSR). Data were stratified by type of repair and sex. Logistic regression models were used to estimate odds ratio (OR) for the association between AAA diameter and perioperative mortality and the association between type of repair and mortality. Multivariable logistic regression models were used to adjust for differences in patient characteristics. RESULTS The study population consisted of 6428 patients with a mean age ranging from 70.2 to 75.4 years; the mean AAA diameter was 7.7 ± 1.8 cm. Females had a significantly smaller AAA diameter at presentation compared with males (6.9 ± 1.6 cm vs 7.9 ± 1.8 cm; P < .001). who underwent OSR had larger AAA diameters compared with those who underwent EVAR (P < .001). Females who underwent repair were significantly older (P < .001). Males were more likely to have cardiac disease, diabetes mellitus, and renal impairment. Overall, AAA diameter was a predictor of mortality in univariate and multivariate analysis. When analyzing EVAR and OSR separately, the impact of AAA diameter per cm increase on mortality was apparent in both males and females undergoing EVAR, but not OSR (EVAR: male OR, 1.09 [95% confidence interval, 1.03-1.16] and EVAR: female OR, 1.17 [95% confidence interval, 1.02-1.35]). The early mortality rate for males and females who underwent EVAR was 18.9% and 25.9% (P < .001), respectively. The corresponding mortality for males and females who underwent OSR was 30.2% and 38.6% (P < .001), respectively. CONCLUSIONS In these real-world international data, there is a significant association between rAAA diameters and early mortality in males and females. This association was more evident in patients undergoing EVAR, but not shown in OSR. Despite improvements in overall AAA repair outcomes, the risk of mortality after rAAA repair is consistently higher for females.

Abstract
Purpose The aim of this study was to evaluate the effectiveness of the proposed method of preventive embolization of the internal iliac arteries using a liquid tantalum-containing ethylene vinyl alcohol copolymer. Methods In this nonrandomized clinical study with a retrospective control group, 55 patients with aneurysmal lesions of the infrarenal abdominal aorta participated. In the course of this study, we developed and implemented a method of preventive embolization of the ostia of the internal iliac artery using a liquid tantalum containing ethylene-vinyl alcohol copolymer having viscosity of 34 centipoise. The method was applied in 27 cases in patients with aneurysmal lesions of the infrarenal abdominal aorta with unilateral involvement of the common iliac artery. The maximum follow-up period at the stage of publication of the results was 24 months. Results The proposed method of embolization of the internal iliac artery is accompanied by an absolute risk of developing type II endoleak 0.393 (95% confidence interval: 0.2120-0.5738, p = 0.029); therefore, when using the new technique, there is a decrease in the absolute risk of developing type II endoleak by 39.3%. Conclusion The proposed method of preventive embolization allows to perform reliable occlusion of the internal iliac artery as proximally as possible, which makes it possible to maintain distal blood flow in the internal iliac artery and minimizes the risks of ischemic events.

Abstract
Sex-based outcome studies have consistently documented worse results for females undergoing care for abdominal aortic aneurysms. This review explores the underlying factors that account for worse outcomes in the females sex. A scoping review of studies reporting sex-based disparities on abdominal aortic aneurysms was performed. The review was conducted in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for scoping reviews. Factors that account for worse outcomes in the females sex were identified, grouped into themes, and analyzed. Key findings of each study are reported and a comprehensive framework of these factors is presented. A total of 35 studies were identified as critical in highlighting sex-based disparities in care of patients with aortic aneurysms. We identified the following 10 interrelated themes in the chain of aneurysm care that account for differential outcomes in females: natural history, risk factors, pathobiology, biomechanics, screening, morphology, device design and adherence to instructions for use, technique, trial enrollment, and social determinants. Factors accounting for worse outcomes in the care of females with aortic aneurysms were identified and described. Some factors are immediately actionable, such as screening criteria, whereas device design improvement will require further research and development. This comprehensive framework of factors affecting care of aneurysms in females should serve as a blueprint to develop education, outreach, and future research efforts to improve outcomes in females.

The Comparison of Endovascular and Open Surgical Treatment for Ruptured Abdominal Aortic Aneurysm in Terms of Safety and Efficacy on the Basis of a Single-Center 30-Year Experience. J Clin Med 2023; 12:7186. [PMID: 38002798 PMCID: PMC10672125 DOI: 10.3390/jcm12227186] [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: 10/08/2023] [Revised: 11/14/2023] [Accepted: 11/17/2023] [Indexed: 11/26/2023] Open
Abstract
OBJECTIVE Ruptured abdominal aortic aneurysm (rAAA) is a critical condition with a high mortality rate. Over the years, endovascular aortic repair (EVAR) has evolved as a viable treatment option in addition to open repair (OR). The primary objective of this study was to compare the safety and efficacy of EVAR and OR for the treatment of rAAA based on a comprehensive analysis of our single-centre 30-year experience. METHODS Patients treated for rAAA at the Department of Vascular and Endovascular Surgery, University Hospital Düsseldorf, Germany from 1 January 1993 to 31 December 2022 were included. Relevant information was retrieved from archived medical records. Patient survival and surgery-related complications were analysed. RESULTS None of the patient-specific markers, emergency department-associated parameters, and co-morbidities were associated with patient survival. The 30-day and in-hospital mortality was higher in the OR group vs. in the EVAR group (50% vs. 8.7% and 57.1% vs. 13%, respectively). OR was associated with more frequent occurrence of more severe complications when compared to EVAR. Overall patient survival was 56 ± 5% at 12 months post-surgery (52 ± 6% for OR vs. 73 ± 11% for EVAR, respectively) (p < 0.05). Patients ≥70 years of age showed poorer survival in the OR group, with a 12-month survival of 42 ± 7% vs. 70 ± 10% for patients <70 years of age (p < 0.05). In the EVAR group, this age-related survival advantage was not found (12-month survival: ≥70 years: 67 ± 14%, <70 years: 86 ± 13%). Gender-specific survival was similar regardless of the applied method of care. CONCLUSION OR was associated with more severe complications in our study. EVAR initially outperformed OR for rAAA regarding patient survival while re-interventions following EVAR negatively affect survival in the long-term. Elderly patients should be treated with EVAR. Gender does not seem to have a significant impact on survival.

Abstract
OBJECTIVE Although the differences in short-term outcomes between male and female patients in abdominal aortic aneurysm (AAA) repair have been well studied, it remains unclear if these sex disparities extend to other long-term adverse outcomes after AAA repair, such as reintervention and late rupture. METHODS We performed a retrospective cohort study of 13,007 patients who underwent either endovascular (EVAR) or open AAA repair (OAR) between 2003 and 2015 using data from the Vascular Quality Initiative registries. Eligible patients were linked to fee-for-service Medicare claims to identify late outcomes of rupture and aneurysm-specific reintervention. RESULTS The mean age of our cohort was 76 ± 6.7 years, 22% were female, 94% were White, and 77% underwent EVAR. The 10-year rupture incidence was slightly higher for women at 4.8 per 1000 person-years, vs 3.9 for men, but this difference was not statistically significant after risk adjustment (hazard ratio [HR] = 1.13, 95% confidence interval [CI]: 0.74-1.73). Likewise, we found no sex difference in reintervention rates (5.1 vs 4.8 in women per 1000 person-years) even after risk adjustment (HR = 0.95, 95% CI: 0.83-1.09). Regression models suggest effect modification by repair type for reintervention, where women who underwent index EVAR had a higher risk of reintervention than men (HR = 1.08, 95% CI: 0.93-1.26), whereas women who underwent OAR were at a lower risk of reintervention than men (HR = 0.79, 95% CI: 0.58-1.08); however, neither effect reached statistical significance within each subgroup. In addition, we found that the risk of reintervention for women vs men varied by clinical presentation, where women were less likely to undergo reintervention after an elective or symptomatic AAA repair but were more likely to undergo reintervention after a repair for AAA rupture (HR = 1.70, 95% CI: 1.05-2.75). CONCLUSIONS Male and female patients who underwent AAA repair had similar rates of reintervention and late aneurysm rupture in the 10 years after their procedure. However, our findings suggest that repair type and clinical presentation may affect the role of sex in clinical outcomes and warrant further exploration in these subgroups.

Abstract
INTRODUCTION Female sex is a risk factor of post-operative mortality and morbidity after abdominal aortic aneurysm (AAA) repair. The aim of this systematic review is to assess the sex-specific early mortality following both elective and urgent AAA repair. EVIDENCE ACQUISITION The Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines were followed. Observational studies (2000-2022), of the English medical literature, focusing on early mortality after AAA repair in females under elective or urgent setting were eligible. A systematic search of MEDLINE, EMBASE and CENTRAL databases, was conducted (November 30th, 2022). The risk of bias was assessed using the Newcastle-Ottawa Scale. Primary outcome was 30-day mortality in relevant strata. A proportional metanalysis was used to assess the estimates. EVIDENCE SYNTHESIS Seventeen retrospective studies and 83,738 females were included. Thereof 68.7% underwent elective repair while the remaining were managed urgently. Endovascular repair (EVAR) was applied in 37.3% of patients (15.4% urgent) vs. 62.7% with OSR (23.5% urgent). In the total cohort, the perioperative mortality was estimated at 11% (OR, 95% CI: 5-17%, P<0.01, I2 99.92%) while 3% (OR, 95% CI: 0.02-0.03, P<0.01, I2 93.42%) deceased after elective repair (2% OR, 95% CI 0.01-0.02, P<0.01, I2 83.08%, after EVAR and 5% (OR, 95% CI: 0.05-0.06, P<0.01, I2 77.36%, after OSR) and 36% (OR, 95% CI: 0.28-0.44, P<0.01, I2 99.51%) after urgent repair (25% OR, 95% CI: 0.16-0.34, P<0.01, I2 98.45%, after EVAR and 40% (OR, 95% CI: 0.34-0.46, P<0.01, I2 95.96%, after OSR). CONCLUSIONS AAA repair in females appears to be associated with considerable postoperative mortality. Despite the rapid development of innovative techniques and intensive care of severely ill patients, perioperative mortality after ruptured AAA remains devastatingly high.

Abstract
INTRODUCTION Studies comparing male and female patients with abdominal aortic aneurysms have shown that female patients are generally older and more often experience postoperative complications after endovascular and open repair. There are also indications that female patients have more extensive neck pathologies and that they more often have postoperative complications related to proximal neck pathology. MATERIAL AND METHODS This retrospective study describes all consecutive female patients who underwent EVAR between 1 January 2012 and 31 December 2021. Propensity-score matching was used to obtain a matched control male cohort. Propensity scores were generated with the following anatomic parameters: infrarenal and suprarenal angulation, proximal and distal neck diameter and neck length. 1 Female patient was matched with 3 male patients. RESULTS A total of 160 patients were included, namely 120 male patients and 40 female patients. Due to matching, there were no significant differences regarding infrarenal and suprarenal angulation and proximal and distal neck diameter and length. All-cause and aneurysm-related mortality were comparable (p = 0.19 and p = 0.98). The necessity of neck-related secondary procedures was significantly higher in female patients (p = 0.02). In the multivariate analysis, the female sex was a significant predictor of endoleak type IA within 30 days. However, there was no significant association between intraoperative endoleak type IA and endoleak type IA at the end of follow-up. CONCLUSIONS This study suggests that there was a higher initial incidence of endoleak type IA in female patients, despite thematched preoperative anatomic parameter. Due to the relatively low number of included female patients, conclusions should be drawn carefully.

Abstract
BACKGROUND There is significant debate regarding the existence of sex-related differences in the presentation, treatment, and outcomes of men versus women affected by abdominal aortic aneurysm (AAA). The purpose of this study is to compare endovascular aneurysm repair (EVAR) of infrarenal AAAs with the current sex-neutral 5.0-5.5 cm-diameter threshold for intervention between the two sexes. METHODS Retrospective review of consecutive cases from a single teaching institution over a period of five years of patients who had undergone elective EVAR for AAAs between 5.0 and 5.5 cm in diameter. Outcomes of interest were compared according to sex. RESULTS Ninety-four patients were included in the analysis, with a higher prevalence of men (53%). Females were older at the time of repair, 78 ± 5.1 years, versus 71.7 ± 7 years (p < 0.01), and had higher incidence of underlying comorbidities, namely, arrhythmia, chronic kidney disease, and previous carotid revascularization. Women had higher incidence of immediate systemic complications (p = 0.021), post-operative AMI (p = 0.001), arrhythmia (p = 0.006), pulmonary oedema (p < 0.001), and persistent renal dysfunction (p = 0.029). Multivariate analysis for post-operative factors associated to mortality and adjusted for sex confirmed that AMI (p = 0.015), arrhythmia (p = 0.049), pulmonary oedema (p = 0.015), persistent renal dysfunction (p < 0.001), cerebral ischemia (p < 0.001), arterial embolism of lower limbs (p < 0.001), and deep-vein thrombosis of lower limbs (p < 0.001) were associated to higher EVAR-related mortality; a higher incidence of post-operative AMI (p = 0.014), pulmonary edema (p = 0.034), and arterial embolism of lower limbs (p = 0.046) were associated to higher 30-days mortality. In females there was also a higher rate of suprarenal fixation (p = 0.026), insertion outside the instruction for use (p = 0.035), and a more hostile neck anatomy with different proximal aortic diameter (p < 0.001) and angle (p = 0.003). CONCLUSIONS A similar threshold of size of AAA for elective surgery for both males and females might not be appropriate for surgical intervention, as females tend to have worse outcomes. Further population-based studies are needed to guide on sex-related differences and intervention on AAA.

Abstract
BACKGROUND Peripheral artery disease (PAD) is associated with worse survival following abdominal aortic aneurysm (AAA) repair. However, little is known about the impact of PAD and sex on outcomes following open infrarenal AAA repair (OAR). METHODS All elective open infrarenal AAA cases were queried from the Society for Vascular Surgery Vascular Quality Initiative from 2003 to 2022. PAD was defined as history of non-cardiac arterial bypass, non-coronary percutaneous vascular intervention (PVI), or non-traumatic major amputation. Cohorts were stratified by sex and history of PAD. Multivariable logistic regression and Cox Proportional Hazards models were constructed to assess the primary endpoints: 30-day and five-year mortality, respectively. RESULTS Of 4,910 patients who underwent elective OAR, 3,421 (69.7%) were men without PAD, 298 (6.1%) were men with PAD, 1,098 (22.4%) were women without PAD, and 93 (1.9%) were women with PAD. Men with PAD had prior bypass (45%), PVI (62%), and amputation (6.7%). Women with PAD had prior bypass (32%), PVI (76%), and amputation (5.4%). Thirty-day mortality was significantly higher in men with PAD compared to men without PAD (4.4% vs 1.7%, p=0.001) and in women with PAD compared to women without PAD (7.5% vs 2.4%, p=0.01). After risk adjustment, when compared to men without PAD, women with PAD had nearly four-times the odds of 30-day mortality (OR 3.86, 95% CI 1.55-9.64, p=0.004) and men with PAD had almost three-times the odds of 30-day mortality (OR 2.77, 95% CI 1.42 - 5.40, p=0.003). Five-year survival was 87.8% in men without PAD, 77.8% in men with PAD, 85% in women without PAD and 76.2% in women with PAD, p<0.001. After risk adjustment, only men with PAD had an increased hazard of death at 5 years (HR 1.52, 95% CI 1.07-2.17, p=0.019) compared to men without PAD. CONCLUSION PAD is a potent risk factor for increased perioperative mortality in both men and women following OAR. In women, this equates to nearly four times the odds of perioperative mortality compared to men without PAD. Future study evaluating risk/benefit is needed to determine if women with PAD reflect a high-risk cohort that may benefit from a more conservative OAR threshold for treatment.

Males and females have similar mortality after thoracic endovascular aortic repair for blunt thoracic aortic injury. J Vasc Surg 2023; 77:997-1005. [PMID: 36565777 DOI: 10.1016/j.jvs.2022.12.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2022] [Revised: 12/06/2022] [Accepted: 12/12/2022] [Indexed: 12/24/2022]
Abstract
OBJECTIVE Prior literature has demonstrated worse outcomes for female patients after abdominal aortic aneurysm repair. Also, prior studies in the context of thoracic endovascular aneurysm repair (TEVAR) for thoracic aortic aneurysms have reported conflicting results regarding sex-related outcomes. Because the influence of sex on the outcomes after TEVAR for blunt thoracic aortic injuries (BTAIs) remains understudied, we evaluated the association between sex and outcomes after TEVAR for BTAI. METHODS We identified patients who had undergone TEVAR for BTAIs in the Vascular Quality Initiative registry from 2013 to 2022 and included those who had undergone TEVAR within zones 2 to 5 of the thoracic aorta. Patients with missing information regarding the aortic injury grade (Society for Vascular Surgery aortic injury grading system) were excluded. We performed multivariable logistic regression and Cox regression to determine the influence of sex on the perioperative outcomes and long-term mortality, respectively. RESULTS We identified 1311 patients, of whom 27% were female. The female patients were significantly older (female, 47 years [interquartile range (IQR), 30-63 years]; male, 38 years [IQR, 28-55 years]; P < .001) with higher rates of comorbidities. Although the female patients had had higher Glasgow coma scale scores (median, 15 [IQR, 11-15]; vs 14 [IQR, 8-15]; P = .028), no differences were found in the aortic injury grade or other coexisting traumatic injuries between the sexes. Apart from the longer procedure duration for the female patients (median, 79 minutes [IQR, 52-119 minutes]; vs 69 minutes [IQR, 48-106 minutes]; P = .008), the procedural characteristics were comparable. After adjustment, no significant association was found between female sex and perioperative mortality (7.1% vs 8.1%; odds ratio, 0.76; 95% confidence interval [CI], 0.43-1.3; P = .34). The male and female patients had had comparable rates of postoperative complications (26% vs 29%; odds ratio, 0.89; 95% CI: 0.52-1.5]; P = .26) including access-related complications (0.5% vs 0.8%; P=.83). However, females had a significantly higher risk for reintervention during the index admission (odds ratio, 2.5; 95% CI, 1.1-5.5; P = .024). No significant difference was found between the male and female patients with respect to 5-year mortality (hazard ratio, 0.87; 95% CI, 0.57-1.35; P = .50). CONCLUSIONS Unlike the sex-based outcome disparities observed after thoracic aortic aneurysm repair, we found no significant association between sex and perioperative outcomes or long-term mortality after TEVAR for BTAIs. This contrast in the sex-related outcomes after other vascular pathologies might be explained by differences in the pathology, demographics, and anatomic factors in these patients.

A Systematic Review of the Recruitment and Outcome Reporting by Sex and Race/Ethnicity in Stent Device Development Trials for Endovascular Abdominal Aortic Aneurysm Repair. Ann Vasc Surg 2023; 89:353-361. [PMID: 36272665 DOI: 10.1016/j.avsg.2022.09.059] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2022] [Revised: 09/20/2022] [Accepted: 09/30/2022] [Indexed: 01/25/2023]
Abstract
BACKGROUND Women and racial/ethnic minority groups have been shown to experience poor outcomes after endovascular aortic aneurysm repair (EVAR). One potential reason is the rare inclusion of these populations in initial phases of device development. The objective of this systematic review is to understand enrollment and outcome reporting by sex and race/ethnicity in industry-funded EVAR device development trials. METHODS MEDLINE, PubMed, and Embase were searched from inception to January 2022 without language restrictions using the following terminology: "stent", "graft", "endograft", "device", and "abdominal aortic aneurysm" (AAA). CLINICALTRIALS gov was also searched from inception to January 2022 for "AAA." Two independent reviewers screened and extracted data. All phase I-III and postmarket evaluation trials that included patients ≥18 years of age, who underwent EVAR were assessed. Participation-to-prevalence ratios (PPRs) were calculated to estimate representation of participants by sex and race/ethnicity in trials compared with their share of disease burden. RESULTS Among the 4,780 retrieved articles, 55 industry-funded trials met inclusion criteria for this review. A total of 51 trials (93%) reported enrollment by sex/gender, and only 7 trials (13%) reported enrollment by race/ethnicity of the participants. A median of 19 (interquartile range [IQR]: 4.5, 51) women participants were recruited compared to 171 (IQR: 57, 311.5) men, and 17 (IQR: 7.5, 21.5) racial/minority patients were recruited compared to 241 (IQR: 123, 463.5) White participants. Women represent 16.6% of the disease population, and the median PPR is 0.62 (IQR: 0.42, 0.88), which has remained constant over time (Figure 1). None of the device trials reported outcomes based on sex/gender or race/ethnicity. CONCLUSIONS This systematic review highlights the disparities in recruitment and outcome reporting based on sex and race/ethnicity in EVAR device development trials. While most trials may be underpowered to study these differences, recent registry studies show differential outcomes based on sex and race/ethnicity of vascular patients. Therefore, it is imperative to include and report outcomes in these participants, starting from the initial device development phases to improve generalizability of device-use and understand sources of variation in device performance.

The measurable impact of a diversity, equity, and inclusion editor on diversifying content, authorship, and peer review participation in the Journal of Vascular Surgery. J Vasc Surg 2023; 77:330-337. [PMID: 36368645 DOI: 10.1016/j.jvs.2022.10.052] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2022] [Revised: 10/09/2022] [Accepted: 10/31/2022] [Indexed: 11/10/2022]
Abstract
OBJECTIVE Women and minorities remain under-represented in academic vascular surgery. This under-representation persists in the editorial peer review process which may contribute to publication bias. In 2020, the Journal of Vascular Surgery (JVS) addressed this by diversifying the editorial board and creating a new Editor of Diversity, Equity, and Inclusion (DEI). The impact of a DEI editor on modifying the output of JVS has not yet been examined. We sought to determine the measurable impact of a DEI editor on diversifying perspectives represented in the journal, and on contributing to changes in the presence of DEI subject matter across published journal content. METHODS The authorship and content of published primary research articles, editorials, and special articles in JVS were examined from November 2019 through July 2022. Publications were examined for the year prior to initiation of the DEI Editor (pre), the year following (post), and from September 2021 to July 2022, accounting for the average 47-week time period from submission to publication in JVS (lag). Presence of DEI topics and women authorship were compared using χ2 tests. RESULTS During the period examined, the number of editorials, guidelines, and other special articles dedicated to DEI topics in the vascular surgery workforce or patient population increased from 0 in the year prior to 4 (16.7%) in the 11-month lag period. The number of editorials, guidelines, and other special articles with women as first or senior authors nearly doubled (24% pre, 44.4% lag; P = .31). Invited commentaries and discussions were increasingly written by women as the study period progressed (18.7% pre, 25.9% post, 42.6% lag; P = .007). The number of primary research articles dedicated to DEI topics increased (5.6% pre, 3.3% post, 8.1% lag; P = .007). Primary research articles written on DEI topics were more likely to have women first or senior authors than non-DEI specific primary research articles (68.0% of all DEI vs 37.5% of a random sampling of non-DEI primary research articles; P < .001). The proportion of distinguished peer reviewers increased (from 2.8% in 2020 to 21.9% in 2021; P < .001). CONCLUSIONS The addition of a DEI editor to JVS significantly impacted the diversification of topics, authorship of editorials, special articles, and invited commentaries, as well as peer review participation. Ongoing efforts are needed to diversify subject matter and perspective in the vascular surgery literature and decrease publication bias.

Females experience elevated early morbidity and mortality but similar mid-term survival compared to males after branched/fenestrated endovascular aortic aneurysm repair. J Vasc Surg 2022; 77:1349-1358.e5. [PMID: 36581014 DOI: 10.1016/j.jvs.2022.12.031] [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: 08/19/2022] [Revised: 11/30/2022] [Accepted: 12/07/2022] [Indexed: 12/28/2022]
Abstract
OBJECTIVE The objective of this study was to identify sex-related differences in outcomes following branched and/or fenestrated endovascular aortic repair (B/FEVAR) for thoracoabdominal (TAAA) and juxtarenal (JRAA) aortic aneurysms. METHODS Chart review completed on 242 B/FEVAR patients (57 female; 23.5%) between 2007 and 2020 at a single center. Median follow-up time was 3.3 years (interquartile range [IQR], 1.6-5.3 years). RESULTS No statistically significant differences in age (females, 75.9 ± 5.4 years vs males, 74.7 ± 7.2 years; P = .162) or aneurysm size (64.9 ± 6.8 vs 65.8 ± 9.4 mm; P = .41) at presentation were observed between sexes. Females presented with fewer JRAAs (45.6% vs 73%; P < .001) and received more Crawford extent II (26.3% vs 10.8%; P =.004) TAAA coverage. Increased incidence of moderate/severe target vessel stenosis (29.8% vs 14%; P = .022) was observed in female patients. Intraoperatively, females had higher procedure times (530 [IQR, 425-625] vs 420 [IQR, 350-510] minutes; P < .001), fluoroscopy times (124.1 ± 49 vs 107.3 ± 43.5 minutes; P = .017), and contrast usage (200 [IQR, 150-270] vs 175 [IQR, 130-225] mL; P = .005). Unplanned intraoperative maneuvers (45.6% vs 28.1%; P = .043), graft delivery issues (24.6% vs 4.9%; P < .001), and additional intraoperative complications (61.4% vs 35.7%; P < .001) were also increased in females. Postoperatively, females had a longer intensive care unit (3 [IQR, 1-5] vs 1 [IQR, 1-3] days; P = .002) and hospital stay (8 [IQR, 5-13] vs 5 [IQR, 3-9] days; P < .001) and experienced increased rates of spinal cord ischemia (15.8% vs 3.8%; P = .001) and bowel ischemia (10.5% vs 2.7%; P = .013). In-hospital mortality (12.3% vs 2.7%; P = .004) was higher in female patients but mid-term (6-year) survival was 60.2% for all patients (95% confidence interval, 53.0%-68.5%) and was similar between sexes (hazard ratio, 0.95; P = .83), which were the primary endpoints. No sex differences in mid-term follow-up reintervention, endoleak, and rupture rates were observed. CONCLUSIONS Females experienced significantly higher B/FEVAR intraoperative times, complications, and in-hospital morbidity and mortality compared with males but similar mid-term outcomes. Anatomic and atherosclerotic differences may have contributed to the observed in-hospital differences.

Abstract
OBJECTIVE While sex differences in endovascular abdominal aortic aneurysm repair (EVAR) outcomes are increasingly reported, but contributing factors remain without consensus. We investigated disparities in sex-specific outcomes following elective EVAR at our institution and evaluated factors that may predispose females to increased morbidity and mortality. METHODS A retrospective chart review of all patients undergoing elective EVAR from 2011 to 2020 at a suburban tertiary care center was performed. The primary outcomes were five-year survival and freedom from reintervention. Fisher's exact test, t-tests, and Kaplan-Meier analysis using the rank-log test investigated associations between sex and outcomes. A multivariable Cox proportional hazard model controlling for age and common comorbidities evaluated the effect of sex on survival and freedom from reintervention. RESULTS Two hundred and seventy-three patients underwent elective EVAR during the study period, including 68 (25%) females and 205 (75%) males. Females were older on average than males (76 years vs. 73 years, p= <0.01) and were more likely to have chronic obstructive pulmonary disease (COPD; 38% versus 23%, p=0.01), require home oxygen therapy (9% versus 2%, p=0.04) or dialysis preoperatively (4% versus 0%, p=0.02). Distribution of other common vascular comorbidities was similar between the sexes. Thirty-day readmission was greater in females than males (18% versus 8%, p=0.02). Females had significantly lower survival at five years (48% ± 7.9% versus 65% ± 4.3%, p<0.01) and significantly lower one-year (89% ± 4.1% for females vs. 94% ± 1.7% for males, p=0.01) and five-year freedom from reintervention (69% ± 8.9% versus 84% ± 3.3%, p=0.02). On multivariable analysis, female sex (hazard ratio [HR]: 1.8, 95% confidence interval [CI]: 1.1-2.9), congestive heart failure (HR: 2.2, 95% CI: 1.2-3.9) and age (HR: 1.1, 95% CI: 1.0-1.1) were associated with 5-year mortality. Female sex remained as the only variable with a statistically significant association with five-year reintervention (HR: 2.4, 95% CI: 1.1-4.9). CONCLUSIONS Female sex was associated with decreased five-year survival and increased one and five-year reintervention following elective EVAR. Data from our institution suggests factors beyond patient age and baseline health risk likely contribute to greater surgical morbidity and mortality for females following elective EVAR.

Abstract
Despite declining incidence and mortality rates in many countries, the abdominal aortic aneurysm (AAA) continues to represent a life-threatening cardiovascular condition with an overall prevalence of about 2-3% in the industrialized world. While the risk of AAA development is considerably higher for men of advanced age with a history of smoking, screening programs serve to detect the often asymptomatic condition and prevent aortic rupture with an associated death rate of up to 80%. This review summarizes the current knowledge on identified risk factors, the multifactorial process of pathogenesis, as well as the latest advances in medical treatment and surgical repair to provide a perspective for AAA management.

Incidence and predictive factors for endograft limb patency of the Fenestrated Anaconda™ endograft used for complex endovascular aneurysm repair. J Vasc Surg 2021; 75:1512-1520.e1.

Abstract
OBJECTIVE To describe the incidence, risk factors and outcomes of treatment for limb occlusion in patients treated for complex (thoraco-)abdominal aortic aneurysms (AAA) with the Fenestrated Anaconda™. METHODS Between June 2010 and May 2018, 335 patients underwent elective fenestrated aortic aneurysm repair in 11 participating centers using the Fenestrated Anaconda™ with a median follow-up of 14.3 months (IQR 27.4). The primary outcome measure was freedom-from-limb-occlusion. Secondary outcome measures were freedom-from-limb-related-reintervention, secondary patency, and risk factors associated with limb occlusion. RESULTS Thirty (9.0%) patients presented with limb occlusion during follow-up with freedom-from-limb-occlusion of 98.5%, 91.2%, and 81.7% at 30-days, 1 and 5 years, respectively. In 87% of cases, no obvious cause for limb occlusion was documented. Primary occlusion occurred within 30-days in 36.7% and within 1 year in 80.0%. Twenty-three (6.9%) patients underwent an occlusion-related reintervention; seven (23.3%) patients were treated conservatively. Freedom-from-limb-occlusion-related-reintervention at 30-days, one and five years was 97.8%, 93.2% and 88.6%, respectively. Secondary patency was 91.3% after 1-month and 86.2% after 1 and 5 years, respectively. Female sex (OR 3.27 - 95% CI 1.28 to 8.34, P = .01) was a statistically significant predictor for limb occlusion. A higher percentage of thrombus in the aneurysm sac appeared to be protective for limb occlusion (0% compared to <25%: OR 0.22 - 95% CI 0.07 to 0.63, P = .01; 0% compared to 25-50%: OR 0.20 - 95% CI 0.07 to 0.57, P = .00 and 0% compared to >50%: OR 0.08 - 95% CI 0.02 to 0.38, P = .00), as did iliac angulation (OR 0.99 - 95% CI 0.98 to 1.00, P = .04). CONCLUSION Limb occlusion remains a significant impediment of endograft durability in patients treated with the Fenestrated Anaconda™, especially in female patients. Controversially, a high aneurysmal thrombus load and a high degree of iliac angulation appeared to be protective for limb occlusion, for which no obvious cause could be identified.

A systematic review and meta-analysis on early mortality after abdominal aortic aneurysm repair in females in urgent and elective setting. J Vasc Surg 2021; 75:1082-1088.e6. [PMID: 34740807 DOI: 10.1016/j.jvs.2021.10.040] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2021] [Accepted: 10/24/2021] [Indexed: 12/19/2022]
Abstract
OBJECTIVE Females represent a group of patients with higher mortality after abdominal aortic aneurysm (AAA), endovascular (EVAR) or open (OSR), repair. This systematic review aimed to evaluate the 30-day mortality after AAA repair in females, comparing both EVAR and OSR, in elective and urgent settings. METHODS The protocol of the review was registered to the PROSPERO (CRD42021242686). A search of the English literature was conducted, using PubMed, EMBASE and CENTRAL databases, from inception to March 5, 2021, using the Systematic Reviews and Meta-Analysis guidelines (PRISMA). Only studies reporting on 30-day mortality of AAA repair, in urgent and elective setting, comparing EVAR and OSR, in female population were eligible. Patients were stratified according to the need for elective or urgent repair. Symptomatic and ruptured cases were included into the urgent group. Individual studies were assessed for risk of bias using the ROBINS-I tool. The GRADE approach was used to evaluate the quality of evidence. The primary outcome was 30-day mortality after AAA repair in the female population, comparing EVAR and OSR. The outcomes were summarized as odds ratio along with their 95% confidence intervals (CI), through a paired meta-analysis. RESULTS Eight studies reported data on 30-day mortality following AAA repair. A total of 56,982 females (22,995 EVAR vs. 33,987 OSR) were included. A significantly reduced total 30-day mortality rate was recorded among females that underwent EVAR compared to OSR (OR, 0.25; 95% CI, 0.23-0.27; P<.001, Ι2=86%). Also a reduced 30-day mortality was found in females that underwent elective EVAR compared to OSR (OR, 0.37; 95% CI, 0.33-0.41; P< .001, Ι2=48%). Despite that OSR was more frequently offered in the urgent setting (OR, 0.21; 95% CI, 0.19-0.23; P< .001, Ι2=84%), EVAR was associated with a reduced 30-day mortality (OR, 0.48; 95% CI, 0.40-0.57; P<.001, Ι2=0%). CONCLUSIONS In females, EVAR is associated with lower 30-day mortality in both elective and urgent AAA repair, although it appears as less likely to be offered in the setting of urgent AAA repair.

Abstract
INTRODUCTION While there exists copious short-term data regarding renal function following infra-renal endovascular abdominal aortic aneurysm repair (EVAR), long-term analysis is sparse. This is a single institution retrospective review of predictors of renal function decline 5 years after elective EVAR. METHODS All EVAR between 2007 and 2015 were queried. Patients in whom renal function was documented 5 years postoperatively were included in analysis. Exclusion criteria were ruptured aneurysm, mortality before 56 months, lack of follow-up, ESRD status, and concomitant renal intervention. The primary outcome investigated was a 20% or greater drop in glomerular filtration rate (GFR) 5 years postoperatively. The following variables at the time of surgery were investigated as potential predictors: age, gender, hypertension, hyperlipidemia, diabetes, CAD or prior MI, COPD, prior stroke, baseline eGFR under 60 mL/min/1.73 m2, supra-renal fixation, infra-renal fixation, neck diameter, neck length, and number of contrast CT. RESULTS 354 EVAR were identified of which 143 met inclusion criteria (211 excluded). Univariate analysis revealed female gender (OR 2.7), hypertension (OR 9.4), baseline renal insufficiency (OR 3.8), larger neck diameter, and supra-renal fixation (OR 2.32) all predictive (P < .05) of GFR drop at 5 years. Multivariate binary logistic regression analysis found female gender (multivariate OR 3.9, P = .023) and baseline renal insufficiency (multivariate OR 3.0, P = .029) as significant predictors of greater than 20% GFR drop at 5 years. Only 2 patients of the 143 progressed to dialysis requirement at 5 years. CONCLUSIONS Females and patients with baseline renal insufficiency are more vulnerable to significant decline in renal function 5 years following EVAR. Consistent with analogous literature, supra-renal fixation appears moderately deleterious toward renal function with no clinical significance in those with baseline normal renal function. The potential benefit of avoidance of supra-renal fixation in female patients with baseline renal insufficiency is worth further investigation in a more robust multi-center study.

Eur J Vasc Endovasc Surg 2021; 62:367-378. [PMID: 34332836 DOI: 10.1016/j.ejvs.2021.05.029] [Citation(s) in RCA: 32] [Impact Index Per Article: 10.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2021] [Revised: 05/12/2021] [Accepted: 05/23/2021] [Indexed: 10/20/2022]
Abstract
OBJECTIVE Previously, reports have shown that women experience a higher mortality rate than men after elective open (OAR) and endovascular (EVAR) repair of abdominal aortic aneurysm (AAA). With recent improvements in overall AAA repair outcomes, this study aimed to identify whether sex specific disparity has been ameliorated by modern practice, and to define sex specific differences in peri- and post-operative complications and pre-operative status; factors which may contribute to poor outcome. METHODS This was a systematic review, meta-analysis, and meta-regression of sex specific differences in 30 day mortality and complications conducted according to PRISMA guidance (Prospero registration CRD42020176398). Papers with ≥ 50 women, reporting sex specific outcomes, following intact primary AAA repair, from 2000 to 2020 worldwide were included; with separate analyses for EVAR and OAR. Data sources were Medline, Embase, and CENTRAL databases 2005 - 2020 searched using ProQuest Dialog. RESULTS Twenty-six studies (371 215 men, 65 465 women) were included. Meta-analysis and meta-regression indicated that sex specific odds ratios (ORs) for 30 day mortality were unchanged from 2000 to 2020. Mortality risk was higher in women for OAR and more so for EVAR (OR [95% CI] 1.49 [1.37 - 1.61]; 1.86 [1.59 - 2.17], respectively) and this remained following multivariable risk adjustment. Transfusion, pulmonary complications, and bowel ischaemia were more common in women after OAR and EVAR (OAR: ORs 1.81 [1.60 - 2.04], 1.40 [1.28 - 1.53], 1.54 [1.36 - 1.75]; EVAR: ORs 2.18 [2.08 - 2.29] 1.44 [1.17 - 1.77], 1.99 [1.51 - 2.62], respectively). Arterial injury, limb ischaemia, renal and cardiac complications were more common in women after EVAR (ORs 3.02 [1.62 - 5.65], 2.13 [1.48 - 3.06], 1.46 [1.22 - 1.72] and 1.19 [1.03 - 1.37], respectively); the latter was associated with greater mortality risk on meta-regression. CONCLUSION Increased mortality risk for women following AAA repair remains. Women had a higher incidence of transfusion, pulmonary and bowel complications after EVAR and OAR. Higher mortality risk ratios for EVAR may result from cardiac complications, additional arterial injury, and embolisation, leading to renal and limb ischaemia. These findings indicate possible causes for observed outcome disparities and targets for quality improvement.

Abstract
OBJECTIVE Outcomes for intact abdominal aortic aneurysm (AAA) repair vary over time and by healthcare system, country, and surgeon. The aim of this study was to analyse peri-operative mortality for intact AAA repair in 11 countries over time and compare outcomes by gender, age, and geographical location. METHODS Prospective data on primary repair of intact AAA were collected from 11 countries through the International Consortium of Vascular Registries (ICVR) and analysed for two time periods, 2010 - 2013 and 2014 - 2016. The primary outcome was peri-operative mortality after endovascular aneurysm repair (EVAR) and open surgical repair (OSR). Multivariable logistic regression models were used to adjust for differences in patient characteristics. RESULTS A total of 103 715 patients were included. The percentage of patients undergoing EVAR increased from 63.6% to 71.2% (p < .001) over the study period. This proportion varied by country from 35% in Hungary to 81% in the United States. Overall peri-operative mortality decreased from 2.1% to 1.6 % (p < .001). Mortality also declined significantly over time for both OSR 4.2% to 3.6 % (p = .002) and EVAR 1.0% to 0.7% (p = .002). Mortality was significantly higher for female than male patients (3.0% vs. 1.6% p < .001). The percentage of patients > 80 years old undergoing AAA repair remained constant at 23.6% (p = .91). Peri-operative mortality was higher for patients > 80 years than for those < 80 years old (2.7% vs. 1.6% p < .001). Forty-six per cent (n = 275) of all EVAR deaths occurred in the over 80s. CONCLUSION The proportion of AAA repairs performed using EVAR has increased over time. Peri-operative mortality continues to decline for both OSR and EVAR. Outcomes however were significantly worse for both women and those aged over 80, so efforts should be focused on these patient groups to further reduce elective AAA mortality rates.

Abstract
OBJECTIVE Endograft sizing for endovascular abdominal aortic aneurysm repair (EVAR) is not consistent despite published instructions for use (IFU). We sought to identify factors associated with over/undersizing, determine sex influence on sizing, and examine sizing effects on endoleak, reintervention, and mortality by analyzing data obtained from the W.L. Gore & Associates Global Registry for Endovascular Aortic Treatment (GREAT). METHODS All patients enrolled in GREAT undergoing EVAR were included for analysis. Proximal/distal aortic landing zones were compared with device implanted to assess sizing as related to IFU. χ2/Fisher exact tests were used to evaluate associations between IFU sizing and demographics. Logistic regression modeling was used to identify predictors of outside IFU sizing. Cox proportional hazards regression analyzed the relationship between sizing and endoleak, device-related reinterventions, and all-cause/aortic mortality. RESULTS There were 3607 EVAR subjects enrolled in GREAT as of March 2020. Of them, 1896 (53%) were within IFU for sizing, 791 (22%) were oversized, 540 (15%) were undersized, and 380 (10%) had both over- and undersized components. Factors predictive of use outside of IFU included female sex (P = .001), non-white race (P = .0003), decreased proximal neck length (P < .061), or larger iliac diameters (P < .0001). Women were more likely than men to have proximal neck undersizing and iliac limb oversizing, and men were more likely to have iliac limb undersizing. On multivariate analysis, undersizing of the proximal graft was associated with endoleak (hazard ratio [HR], 1.8) and aortic (HR, 60.5) and all-cause (HR, 18.0) mortality. Undersizing of iliac limbs was associated with endoleak (HR, 1.5) and device-related reintervention (HR, 1.4). Iliac limb outside IFU sizing was associated with aortic (HR, 2.6) and all-cause (HR, 1.3) mortality. Proximal and distal oversizing was not associated with adverse outcomes. Female sex was associated with mortality on univariate but not multivariate analysis. CONCLUSIONS Women undergoing EVAR with GORE EXCLUDER abdominal aortic aneurysm Endoprosthesis (W.L. Gore & Associates Inc, Flagstaff, Ariz) are more likely to have proximal stent-graft undersizing and iliac limb oversizing, whereas men are more likely to have undersized iliac limbs. Proximal aortic graft undersizing is associated with endoleak and all-cause/aortic mortality, whereas undersizing of iliac limbs is associated with endoleak and device-related reintervention. Oversizing was not associated with adverse outcomes.

Abstract
OBJECTIVE Sex disparities regarding outcomes for women after open and endovascular abdominal aortic aneurysm repair have been well-documented. The purpose of this study was to review whether these disparities were also present at our institution for elective endovascular aneurysm repair (EVAR) and whether specific factors predispose female patients to negative outcomes. METHODS All elective EVARs were identified from our three sites (Florida, Minnesota, and Arizona) from 2000 to 2018. The primary outcome was in-hospital mortality and three-year mortality. Secondary outcomes included complications requiring return to the operating room, length of hospitalization (LOH), intensive care unit (ICU) days, and location of discharge after hospitalization. Multivariable logistic regression models were used to assess for the risk of complications. RESULTS There were 1986 EVARs; 1754 (88.3%) were performed in male and 232 (11.7%) in female patients. Female patients were older (79 years [interquartile range (IQR), 72-83 years] vs 76 years [IQR, 70-81 years]; P < .001), had a lower body mass index (median, 26.1 kg/m2 [IQR, 22.1-31.0 kg/m2] vs 28.3 kg/m2 [IQR, 25.3-31.6 kg/m2]; P < .001 and hematocrit (median, 37.6% [IQR, 33.4%-40.6%] vs 39.4% [IQR, 35.6%-42.6%]; P < .001) and had higher glomerular filtration rate (median, 84.4 mL/min per 1.73m2 [IQR, 62.3-103 mL/min/1.73 m2] vs 51.1 mL/min/1.73 m2 [IQR, 41.8-60.8 mL/min/1.73 m2]; P < .001. Female patients were also more likely to be active smokers (15.3% vs 13.1%; P < .001) and have chronic obstructive pulmonary disease (24.7% vs 15.3%; P = .001). They were less likely to have coronary artery disease (31.6% vs 45.6%; P < .001). Aneurysms in women were slightly smaller in size (median, 54 mm [IQR, 50.0-58.0 mm] vs 55 mm [IQR, 51.0-60.0 mm]; P = .004). In-hospital mortality and mortality at the 3-year follow-up was not significant between female and male patients (0.86% vs 0.17%; P = .11 and 38.4% vs 36.2%; P = .57). However, female patients returned to the operating room with a greater frequency than male patients (3.9% vs 1.4%; P = .011). LOH (mean, 3.4 ± 3.8 days vs 2.5 ± 2.4 days; P < .001) and ICU days (mean, 0.3 ± 2.0 days vs 0.1 ± 0.5 days; P < .001) were longer for female patients. After hospitalization, female patients were discharged to rehabilitation facilities in greater proportion (12.7% vs 3.1%; P < .001) than their male counterparts. On multivariable analysis, female sex was associated with a return to the operating room (odds ratio, 6.4; 95% confidence interval [CI], 1.4-3.5; P = .02), longer LOH (Coef 4.0; 95% CI, 1.0-2.5; P = .00007), more ICU days (Coef 2.8; 95% CI, 1.1-3.0; P = .005), and a greater likelihood of posthospitalization rehabilitation facility placement (odds ratio, 5.8; 95% CI, 1.5-2.4; P = .0001). CONCLUSIONS Our three-site, single-institution data support sex disparities to the detriment of female patients regarding return to the operating room after EVAR, LOH, ICU days, and discharge to rehabilitation facility. However, we found no differences for in-hospital or 3-year mortality.

Abstract
We aimed to investigate whether sex differences influence the clinical outcomes of patients who undergo thoracic endovascular aortic repair (TEVAR) for type B aortic dissection (TBAD). We retrospectively analyzed a prospectively maintained single-center cohort of patients with TBAD who underwent TEVAR between January 2010 and June 2017. We evaluated the in-hospital and long-term mortality and composite end point. Of the 913 patients, 793 (86.8%) were male and 120 (13.1%) were female. Compared to male patients, the female patients were older, more likely to have diabetes mellitus, but less likely to smoke or have hypertension. The proximal landing zone in 0 and 1 was higher in male patients (P = .023), who were more likely to require an aortic arch bypass. Endoleak, delirium, and ICU stay after stent-graft implantation were also more frequent in men. Sex factor was not associated with in-hospital or long-term mortality or the composite end point in the multivariable regression analyses and Cox regression model. The mean estimated survival time was similar between males and females (2462.9 ± 141.2 vs 2804.1 ± 117.4 days, P = .167) in the propensity score-matched cohort. Despite distinct characteristics between sex, there was no sex-related difference in long-term clinical outcomes after TEVAR for TBAD.

Female Sex and Outcomes after Endovascular Aneurysm Repair for Abdominal Aortic Aneurysm: A Propensity Score Matched Cohort Analysis. J Clin Med 2021; 10:jcm10010162. [PMID: 33466535 PMCID: PMC7796519 DOI: 10.3390/jcm10010162] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2020] [Revised: 01/01/2021] [Accepted: 01/02/2021] [Indexed: 12/13/2022] Open
Abstract
OBJECTIVE Previous studies have showed a potential disadvantage of female patients who underwent abdominal aortic aneurysm (AAA) repair. The current study aims to determine sex-specific perioperative and long-term outcomes using propensity score matched unselected nationwide health insurance claims data. METHODS Insurance claims from a large German fund were used, covering around 8% of the insured German population. Patients who underwent endovascular aortic repair (EVAR) for intact AAA from 1 January 2011 to 30 April 2017 were included in the cohort. A 1:2 female to male propensity score matching was applied to adjust for confounding variables. Perioperative and long-term outcomes after 5 years were determined using matching and regression methods. RESULTS Among a total of 3736 patients (19.3% females, mean 75 years) undergoing EVAR for intact AAA, we identified 1863 matched patients. Before matching, females were more likely to be previously diagnosed with hypothyroidism, electrolyte disorders, rheumatoid disorders, and depression, while males were more often diabetics. In the matched sample, 23.4% of the females and 25.8% of the males died during a median follow-up of 776 and 792 days, respectively. Perioperatively, females were more likely to exhibit acute limb ischemia (5.3% vs. 3.2%, p = 0.031) and major bleeding (22.0% vs. 15.9%, p = 0.001) before they were discharged to rehabilitation (5.5% vs. 1.5%, p < 0.001) when compared to males. No statistically significant difference in perioperative (odds ratio 1.12, 95% CI 0.54-2.16) or long-term mortality (hazard ratio 0.91, 95% CI 0.76-1.08) was observed between sexes. This was also true regarding aortic reintervention rates after 1 year (2.0% vs. 2.9%) and 5 years (10.9% vs. 8.1%). CONCLUSION The current retrospective matched analysis of insurance claims revealed high early access-related morbidity in females when compared to their male counterparts. Short-term or long-term survival and reintervention outcomes were similar between sexes.

Abstract
BACKGROUND This review presents the surgical indications, surgical procedures, and results in the treatment of asymptomatic and ruptured abdominal aortic aneurysms (AAA). METHODS An updated search of the literature on screening, diagnosis, treatment, and follow-up of AAA, based on the German clinical practice guideline published in 2018. RESULTS Surgery is indicated in men with an asymptomatic AAA ≥ 5.5 cm and in women, ≥ 5.0 cm. The indication in men is based on four randomized trials, while in women the data are not conclusive. The majority of patients with AAA (around 80%) meanwhile receive endovascular treatment (endovascular aortic repair, EVAR). Open surgery (open aneurysm repair, OAR) is reserved for patients with longer life expectancy and lower morbidity. The pooled 30-day mortality is 1.16% (95% confidence interval [0.92; 1.39]) following EVAR, 3.27% [2.7; 3.83] after OAR. Women have higher operative/interventional mortality than men (odds ratio 1.67%). The mortality for ruptured AAA is extremely high: around 80% of women and 70% of men die after AAA rupture. Ruptured AAA should, if possible, be treated via the endovascular approach, ideally with the patient under local anesthesia. Treatment at specialized centers guarantees the required expertise and infrastructure. Long-term periodic monitoring by mean of imaging (duplex sonography, plus computed tomography if needed) is essential, particularly following EVAR, to detect and (if appropriate) treat endoleaks, to document stable diameter of the eliminated aneurysmal sac, and to determine whether reintervention is necessary (long-term reintervention rate circa 18%). CONCLUSION Vascular surgery now offers a high degree of safety in the treatment of patients with asymptomatic AAA. Endovascular intervention is preferred.

Abstract
BACKGROUND Inferior perioperative outcomes for women receiving major vascular surgery are well established in the literature in multiple arterial distributions. Therefore, this study was completed to determine the perioperative and durability results associated with women undergoing complex aortic reconstruction using the Zenith Fenestrated platform (ZFEN; Cook Medical, Bloomington, IN). METHODS A retrospective review of a fenestrated endovascular aortic repair (FEVAR) database capturing all ZFENs performed at our institution between October 2012 and March 2019 was completed. Preoperative, intraoperative, perioperative, and follow-up outcomes were tabulated for females and compared with their male counterparts. RESULTS Within our study period, 136 total ZFEN procedures were performed; of which, 20 devices (14.7%) were implanted in women. Intraoperatively, we observed a higher rate of estimated blood loss (660.0 mL vs. 311.6 mL, P < 0.01) and resultant need for transfusion (1.4 vs. 0.3 units, P < 0.01) in women despite a similar frequency of brachial (5.0% vs. 7.8%, P > 0.99) and femoral artery cutdowns (55.0% vs. 49.1%, P = 0.81). Operative (295.7 min vs. 215.7 mins, P < 0.01) and fluoroscopy (84.3 vs. 58.7 min, P < 0.01) times were also significantly higher in females than those in their male counterparts. In the perioperative (30-day) period, we observed significantly longer length of stay (5.6 days vs. 3.3 days, P = 0.03) and continued need for transfusion (50% vs. 9.5%, P < 0.01) in women. Statistical trends favoring men were also noted with respect to all-cause mortality, reintervention, visceral stent thrombosis, renal failure, acute kidney injury, and respiratory failure. After a mean follow-up of nearly 2 years, we found no differences in late all-cause or aneurysm-related mortality, major adverse cardiovascular events, or need for reinterventions. CONCLUSIONS The implantation of ZFEN in females is significantly more difficult than that in their male counterparts and may result in increased perioperative, but not necessarily long-term, complications.
