Abstract
OBJECTIVE Female sex is associated with worse outcomes after infrarenal abdominal aortic aneurysm (AAA) repair. However, the impact of female sex on complex AAA repair is poorly characterized. Therefore, we compared outcomes between female and male patients after open and endovascular treatment of complex AAA. METHODS We identified all patients who underwent complex aneurysm repair between 2011 and 2017 in the American College of Surgeons National Surgical Quality Improvement Program targeted vascular module. Complex repairs were defined as those for juxtarenal, pararenal, or suprarenal aneurysms. We compared rates of perioperative adverse events between female and male patients stratified by open AAA repair and endovascular aneurysm repair (EVAR). We calculated propensity scores and used inverse probability-weighted logistic regression to identify independent associations between female sex and our outcomes. RESULTS We identified 2270 complex aneurysm repairs, of which 1260 were EVARs (21.4% female) and 1010 were open repairs (30.7% female). After EVAR, female patients had higher rates of perioperative mortality (6.3% vs 2.4%; P = .001) and major complications (15.9% vs 7.6%; P < .001) compared with male patients. In contrast, after open repair, perioperative mortality was not significantly different (7.4% vs 5.6%; P = .3), and the rate of major complications was similar (29.4% vs 27.4%; P = .53) between female and male patients. Furthermore, even though perioperative mortality was significantly lower after EVAR compared with open repair for male patients (2.4% vs 5.6%; P = .001), this difference was not significant for women (6.3% vs 7.4%; P = .60). On multivariable analysis, female sex remained independently associated with higher perioperative mortality (odds ratio [OR], 2.5; 95% confidence interval [CI], 1.3-4.9; P = .007) and major complications (OR, 2.0; 95% CI, 1.3-3.2; P = .002) in patients treated with EVAR but showed no significant association with mortality (OR, 0.9; 95% CI, 0.5-1.6; P = .69) or major complications (OR, 1.1; 95% CI, 0.8-1.5; P = .74) after open repair. However, the association of female sex with higher perioperative mortality in patients undergoing complex EVAR was attenuated when diameter was replaced with aortic size index in the multivariable analysis (OR, 1.9; 95% CI, 0.9-3.9; P = .091). CONCLUSIONS Female sex is associated with higher perioperative mortality and more major complications than for male patients after complex EVAR but not after complex open repair. Continuous efforts are warranted to improve the sex discrepancies in patients undergoing endovascular repair of complex AAA.

Abstract
BACKGROUND The impact of sex in the management of carotid disease is unclear in the current literature. Therefore, we evaluated the effect of sex on perioperative outcomes following carotid endarterectomy (CEA) and carotid artery stenting (CAS). METHODS We included patients who underwent CEA or CAS between 2012 and 2017 in the Vascular Quality Initiative database. Our primary outcome was perioperative stroke/death. Secondary outcomes were in-hospital stroke, 30-day mortality, and in-hospital MI. We compared perioperative outcomes between female and male patients, stratified by treatment modality and symptom status, and used multivariable regression to account for differences in baseline characteristics. RESULTS A total of 83,436 patients underwent either a CEA (71,383) or CAS (12,053). Asymptomatic and symptomatic CEA females were less likely to be on a preoperative antiplatelet agent, when compared to males. Females overall, were less likely to be on a preoperative statin and more likely to have chronic obstructive pulmonary disease. Within the CAS cohort, females were more likely to have a previous ipsilateral CEA. There were no differences between males and females in major adverse events following CEA for asymptomatic disease. Following CEA for symptomatic disease, there was no difference in stroke/death rate or in-hospital stroke. However, females experienced a higher 30-mortality after adjustment (univariate: 1.0% vs 0.7%, P = .04; adjusted: odds ratio [OR], 1.4:1.02-1.94). Following CAS for asymptomatic disease, females experienced a higher rate of perioperative stroke/death (2.9% vs 1.9% P = .02; OR, 1.5: 1.05-2.03) and in-hospital stroke (2.1% vs 1.2% P = .01; OR, 1.8: 1.20-2.60). There were no differences in outcomes for symptomatic females vs males undergoing CAS. CONCLUSIONS Females with carotid disease less frequently receive optimal medical treatment with antiplatelet agents and statins. This is an important target area for quality improvement issue in both females and males. Furthermore, among symptomatic CEA patients the female sex is associated with higher mortality and among asymptomatic CAS patients, females experience higher rates of stroke/death. These findings suggest that careful patient selection is necessary in the treatment of female patients. Quality improvement projects should be created to further investigate and eliminate the disparities of optimal medical management between the sexes.

Abstract
BACKGROUND Liver cirrhosis dramatically increases morbidity and mortality after open surgical procedures and is often a contraindication to open repair of abdominal aortic aneurysms. However, limited data have evaluated the effect of liver disease on outcomes after endovascular repair of aortic aneurysms. METHODS The National Surgical Quality Improvement Program was used to evaluate all nonemergent endovascular aneurysm repairs (EVARs) from 2005 to 2016. The aspartate transaminase to platelet ratio index is a sensitive, noninvasive screening tool used to screen for liver disease and was calculated for all patients. A value >0.5 was used to identify those with significant liver fibrosis. Demographics, comorbidities, and 30-day outcomes were then compared between patients with and patients without fibrosis. Additional analysis was then completed to assess the effect of increasing Model for End-Stage Liver Disease (MELD) score on 30-day outcomes. Multivariable regression was used to account for differences in baseline factors. RESULTS EVAR was performed on 18,484 patients including 2286 with liver fibrosis and 16,198 without. Patients with liver fibrosis had an increased 30-day mortality (1.5% vs 2.4%; P < .01) and significantly higher rates of major morbidities including return to the operating room, pulmonary complications, transfusion, and discharge other than home. After multivariable analysis, patients with liver fibrosis had a significant increase in 30-day mortality (odds ratio [OR], 1.5; 95% confidence interval [CI], 1.1-2.1), return to the operating room (OR, 1.5; 95% CI, 1.2-1.8), pulmonary complications (OR, 1.6; 95% CI, 1.2-2.0), transfusion (OR, 1.7; 95% CI, 1.5-2.0), and discharge other than home (OR, 1.5; 95% CI, 1.3-1.8). In further analysis, mortality also increased in a stepwise fashion with increasing MELD score (MELD <10, 1.3%; MELD 10-15, 2.3%; MELD >15, 4.7%; P < .01), as did major complications (MELD <10, 7%; MELD 10-15, 11%; MELD >15, 15%; P < .01). These increases persisted in adjusted analysis. CONCLUSIONS Liver fibrosis significantly increases mortality and major morbidity after EVAR. The aspartate transaminase to platelet ratio index and MELD score should be used for preoperative risk stratification. Moreover, current 30-day morbidity and mortality rates among patients with MELD scores >10 exceed 5%, which is higher than the annual rupture risk for aneurysms <6 cm. Therefore, an increased size threshold of >6 cm may be warranted before EVAR in patients with liver fibrosis.

Similar 5-year outcomes between female and male patients undergoing elective endovascular abdominal aortic aneurysm repair with the Ovation stent graft. J Vasc Surg 2019; 72:114-121.

Abstract
OBJECTIVE Female patients undergoing endovascular aneurysm repair (EVAR) for infrarenal abdominal aortic aneurysms present with more challenging anatomy and historically have worse outcomes compared with men. The Ovation Abdominal Stent Graft platform (Endologix, Irving, Calif) contains a polymer-filled proximal sealing ring and has a low-profile delivery system, potentially beneficial in female patients. We therefore investigated differences in long-term outcomes between men and women treated with this device. METHODS We used data collected prospectively in the Effectiveness of Custom Seal with Ovation: Review of the Evidence (ENCORE) database, comprising five trials and the European Post-Market Registry. Anatomic characteristics of the proximal aneurysm neck and iliac arteries were compared between male and female patients. Outcomes were 5-year freedom from type IA and type I/III endoleaks, abdominal aortic aneurysm-related reinterventions, and overall survival. We used Kaplan-Meier analysis to estimate survival proportions and tested univariate differences in survival using log-rank tests. Cox proportional hazards modeling was used to adjust for baseline differences. RESULTS We identified 1045 (81%) male and 251 (19%) female patients undergoing EVAR. Female patients were older (mean age, 75 ± 8.4 years vs 73 ± 8.1 years; P < .006). Aneurysm diameter (52 ± 7.5 mm vs 55 ± 9.2 mm; P < .001) and proximal neck diameter (21 ± 3.3 mm vs 23 ± 2.9 mm; P < .001) were smaller in female patients, but adjusted for body surface area, female patients had relatively larger aneurysms and aneurysm necks. Furthermore, female patients presented with shorter proximal necks, smaller iliac artery diameters, more angulated necks, and higher rates of reverse-tapered necks. Five-year freedom from type IA endoleak was similar between men and women (97% vs 96%; P = .38), as was freedom from type I/III endoleaks (91% vs 94%; P = .37) and reinterventions (91% vs 93%; P = .67). Five-year survival was 81% for female patients, similar to the 79% in male patients (P = .55), with one aneurysm-related death in female patients (0.4%) and five in male patients (0.8%; P = .76). Risk-adjusted analyses showed no association between sex and type IA endoleak (hazard ratio [HR], 1.4; 95% confidence interval [CI], 0.6-3.1; P = .41), type I/III endoleak (HR, 1.4; 95% CI, 0.7-2.8; P = .33), reintervention (HR, 1.0; 95% CI, 0.6-2.0; P = .77), and overall mortality (HR, 0.7; 95% CI, 0.4-1.1; P = .14). CONCLUSIONS Female patients undergoing EVAR with the Ovation platform presented with substantially more adverse proximal neck characteristics. Despite these differences, 5-year freedom from endoleaks and overall survival did not differ between sexes.

Abstract
Background and Purpose- Patients undergoing surgery on the weekend may experience worse outcomes, but this weekend effect has not been studied in carotid endarterectomy (CEA). Methods- We identified patients undergoing isolated CEA in the Vascular Quality Initiative between 2003 and 2018. Our primary outcome was in-hospital stroke or perioperative death (stroke/death), stratified by symptom status. For asymptomatic patients, we also compared rates of the Centers for Medicare and Medicaid Services quality metric prolonged length of stay (>2 days or failed discharge home). We calculated propensity scores and used multilevel, inverse probability weighted logistic regression clustering at the hospital level. Results- There were 86 123 repairs during the study period, 53% asymptomatic lesions and 47% symptomatic. Only 0.7% of asymptomatic patients underwent CEA on the weekend, compared with 3.1% of symptomatic patients. Patients undergoing weekend repairs were more often white, with lower rates of most comorbidities. In asymptomatic patients, weekend operations were associated significantly higher odds of stroke/death (odds ratio [OR], 2.3 [1.1-4.8]; P=0.02), and prolonged length of stay (OR, 3.6 [2.7-4.7]; P<0.001). In symptomatic patients, weekend operations were associated with significantly higher adjusted odds of stroke/death (OR, 1.7 [1.2-2.4]; P=0.007) and longer postoperative length of stay (3.3 days versus 2.0 days, P=0.002). However, the difference in stroke/death was driven by patients presenting with stroke (OR, 2.2 [1.5-2.3]; P<0.001), rather than those presenting with transient ischemic attack (OR, 1.2 [0.6-2.1]; P=0.56). Conclusions- We found evidence of a significant weekend effect in CEA, as weekend operations in asymptomatic patients and patients who presented with stroke were associated with higher rates of stroke/death and prolonged length of stay. However, there was no evidence of such an effect in patients with transient ischemic attack. These data suggest that weekend CEA should be avoided except in the case of expedited revascularization after transient ischemic attack.

Abstract
OBJECTIVE Endovascular abdominal aortic aneurysm repair (EVAR) has been rigorously compared with open repair for the treatment of abdominal aortic aneurysms in randomized trials and observational studies, but a comparison of individual devices is lacking, and single-device registries and trials are limited by small sample size. Here we report a descriptive analysis of the Effectiveness of Custom Seal with Ovation: Review of the Evidence (ENCORE) database, pooled results of multiple studies evaluating the midterm results of EVAR with the Ovation Abdominal Stent Graft Platform. METHODS This is a retrospective analysis of the ENCORE database, a cohort of patients undergoing EVAR with the Ovation platform composed of pooled, prospectively collected data from 1296 patients from five clinical trials and the prospectively maintained European Union Post-Market Registry. The primary outcomes were 5-year rates of type IA and type I or III endoleak. Secondary outcomes included were 30-day mortality, 30-day major adverse event, technical success (successful deployment of the aortic body and iliac limbs), as well as 5-year survival, and freedom from aneurysm-related mortality, type II endoleak, device-related intervention, aneurysm rupture, sac expansion, and conversion to open repair. RESULTS A total of 1296 patients were included in the analysis. The average age was 73 ± 8 years and 81% of patients were male. Fifty percent of patients had complex aortic anatomy, (neck length <10 mm, neck diameter >28 mm, neck angle >60°, reverse neck taper >10%, distal common iliac artery diameter <10 mm, or external iliac artery diameter <6 mm). Technical success was 99.7%. Thirty-day mortality was 0.3%, 30-day rate of major adverse event was 1.6%, and polymer leak rate was 0.2%. Freedom from type IA endoleak at 1, 3, and 5 years was 97.6%, 97.1%, and 95.8%, respectively; type I or III endoleak at 1, 3, and 5 years was 96.9%, 95.7%, and 94.0%, respectively. Freedom from device-related reintervention at 1, 3, and 5 years was 96.2%, 94.4%, and 92.4% and primary freedom from sac expansion was 97.0% at 1 year, 90.3% at 3 years, and 84.9% at 5 years. Freedom from all-cause mortality and aneurysm-related mortality at 5 years were 78.9% and 99.3%, respectively. CONCLUSIONS This analysis of the ENCORE database demonstrates that EVAR with the Ovation platform has favorable midterm durability evidenced by successful aneurysm exclusion and 5-year freedom from aneurysm-related mortality.

Abstract
BACKGROUND Open revascularization for acute mesenteric ischemia (AMI) is associated with high perioperative morbidity and mortality; however, results from contemporary studies are varied. Therefore, we evaluated 30-day mortality after open revascularization for AMI and identified preoperative factors associated with mortality. METHODS We performed a retrospective cohort study of patients in the American College of Surgeons National Surgical Quality Improvement Program database undergoing open mesenteric revascularization for AMI from 2005 to 2017. The primary outcome was 30-day mortality. We used multivariable logistic regression to identify preoperative factors independently associated with 30-day mortality. RESULTS The study cohort included 918 patients; their median age was 70 years (interquartile range: 59-80 years), 62% were female, and 90% were white. Thirty-day mortality after open revascularization for AMI was 32%, specifically 35% after embolectomy, 31% after thromboendarterectomy, and 28% after mesenteric bypass. Mortality was higher in patients requiring concomitant bowel resection (38% vs. 29%, respectively, P < 0.01). The preoperative factor most strongly associated with 30-day mortality was disseminated cancer (odds ratio = 8.8, 95% confidence interval = 2.4-32, P = 0.001). Other factors independently associated with mortality were renal dysfunction, preoperative intubation, preoperative blood transfusion, diabetes, elevated preoperative international normalized ratio, elevated preoperative white blood cell count, and increasing age. CONCLUSIONS In this retrospective cohort study using a real-world, nationwide cohort, open revascularization for AMI was associated with high mortality, with nearly one-third of patients dying within 30 days of their operation. The factors identified to be independently associated with 30-day mortality, particularly disseminated cancer, preoperative renal dysfunction, and elevated preoperative WBC count, are an important tool for preoperative risk stratification.

Abstract
OBJECTIVE Transcarotid artery revascularization (TCAR) has emerged as an alternative to transfemoral carotid artery stenting (tfCAS). We investigated the proportion of carotid arteries undergoing revascularization procedures that would be eligible for TCAR based on anatomic criteria and how many arteries at high anatomic risk for tfCAS would be amenable to TCAR. METHODS We performed a retrospective review of consecutive patients who underwent carotid endarterectomy or carotid stenting between 2012 and 2015. Patients were excluded if computed tomography angiography of the neck was not performed within 6 months of the procedure. We assessed TCAR eligibility on the basis of the instructions for use of the ENROUTE Transcarotid Neuroprotection System (Silk Road Medical, Sunnyvale, Calif) and high anatomic risk for tfCAS on the basis of anatomic factors known to make carotid cannulation more difficult or hazardous. RESULTS Of the 118 patients and 236 carotid arteries identified, 12 carotid arteries were excluded for presence of an occluded internal carotid artery (ICA). Of the remaining 224 carotid arteries, 72% were eligible for TCAR on the basis of the instructions for use criteria; 100% had 4- to 9-mm ICA diameters, 100% had ≥6-mm common carotid artery (CCA) diameter, 75% had ≥5-cm clavicle to carotid bifurcation distance, and 96% lacked significant CCA puncture site plaque. In addition, 7% of carotid arteries had bifurcation anatomy unfavorable for stenting; thus, of the entire cohort of arteries examined, 68% were eligible for TCAR. Hyperlipidemia (odds ratio [OR], 6.7; 95% confidence interval [CI], 1.7-26; P < .01), chronic obstructive pulmonary disease (OR, 3.5; 95% CI, 1.5-8.3; P < .01), and older age (OR, 1.1; 95% CI, 1.0-1.1; P < .01) were independently associated with TCAR ineligibility, whereas white race (OR, 0.2; 95% CI, 0.0-1.0; P = .048) and beta-blocker use (OR, 0.3; 95% CI, 0.1-0.7; P < .01) were independently associated with TCAR eligibility. In addition, 24% of carotid arteries were considered to be at high risk for tfCAS for the presence of a type III aortic arch (7.6%), severe aortic calcification (3.3%), tandem CCA lesions (7.1%), moderate to severe stenosis at the carotid ostium (8.9%), and tortuous distal ICA precluding embolic filter placement (4.5%). Active smoking (OR, 4.4; 95% CI, 1.9-10; P < .01), hyperlipidemia (OR, 4.0; 95% CI, 1.2-14; P = .03), and older age (OR, 1.1; 95% CI, 1.0-1.1; P = .02) were independently associated with tfCAS ineligibility, whereas preoperative aspirin (OR, 0.1; 95% CI, 0.0-0.4; P < .001) or clopidogrel (OR, 0.3; 95% CI, 0.1-0.8; P = .01) use was associated with tfCAS eligibility. Of the arteries that were considered to be at high risk for tfCAS, 69% were eligible for TCAR. CONCLUSIONS The majority of carotid arteries in individuals selected for revascularization meet TCAR eligibility, making TCAR a viable treatment option for many patients.

Abstract
OBJECTIVE The factors associated with access site failure after ultrasound-guided percutaneous access for aortic endograft procedures remain poorly characterized. We developed a prediction model to risk stratify patients for access site failure. METHODS We performed a retrospective institutional review of consecutive patients who underwent endovascular aneurysm repair (EVAR), fenestrated EVAR (FEVAR), or thoracic endovascular aortic repair (TEVAR) from 2014 to 2016. We excluded patients undergoing direct aortic access through sternotomy and patients treated with physician-modified endografts, given reporting restrictions. Our primary outcome was groin access site failure, which included bleeding and thrombosis. An 8-point risk model was created for access site failure using multivariable fractional polynomials and internally validated using bootstrapping. RESULTS We identified 469 femoral arteries from 247 patients undergoing endovascular aortic repair procedures (EVAR, 75%; FEVAR, 8.0%; TEVAR, 17%). Surgeons performed percutaneous access in 97.2% of the femoral arteries, with 99.6% ultrasound use. Twenty-seven (5.9%) access site failures occurred (17 bleeding, 10 thrombosis), all treated with groin cutdown, for a successful percutaneous femoral artery access rate of 94%. Of the 215 patients with attempted bilateral percutaneous access, 90% had successful bilateral access. However, FEVAR had lower rates of successful bilateral access (FEVAR, 78%; EVAR, 91%; TEVAR, 94%; P = .03). Factors independently associated with percutaneous access site failure were femoral artery outer wall diameter (per millimeter increase: odds ratio [OR], 0.003 [0.0002-0.1]; P < .001), femoral artery stenosis >50% (OR, 22.3 [2.7-183.2]; P < .01), and urgent/emergent intervention (OR, 3.6 [1.2-11.0]; P = .03). A risk prediction model based on these criteria produced a C statistic of 0.89, a Hosmer-Lemeshow goodness of fit of 0.99, and a Brier score of 0.04. Excluding treatment for ruptured aneurysms, cutdown for access failure and planned initial groin cutdown resulted in longer postoperative lengths of stay and higher rates of access-related readmission, return to operating room, groin infection, and myocardial infarction compared with successful percutaneous access. There was no difference in major adverse events between planned initial groin cutdown and cutdown after failure; however, the small number of patients in these two comparison groups limits the statistical power to detect a difference. CONCLUSIONS Percutaneous ultrasound-guided access can be safely performed in almost all patients undergoing endovascular aortic procedures, but access site failures do occur. This risk score can help users select patients with high likelihood of success, identify patients who need close scrutiny with postclosure femoral duplex ultrasound, and provide patient guidance about risk of unplanned groin cutdown.
