Abstrakt:	Background: Prior studies suggest female sex is associated with worse outcomes after complex endovascular aortic aneurysm repair (EVAR) due to anatomic differences. Therefore, we aimed to compare 30-day perioperative and long-term outcomes after complex EVAR by sex. Methods: A single-center retrospective review of consecutive elective and emergent complex EVAR with company-manufactured devices, laser fenestration, snorkel/periscope, or octopus technique was performed from 2012-2023. The primary outcome was a composite endpoint of any major adverse event (MAE), new-onset dialysis, or death within 30 days. Secondary 30-day technical and long-term outcomes were also assessed. Results: 293 patients (57 females, 19%), mean age 74 years, underwent complex EVAR with commercially available Zenith fenestrated endovascular graft (71%), p-Branch (2%), laser fenestration (8%), snorkel/periscope (16%), or octopus (2%) techniques. Females had significantly different aneurysm-related anatomic characteristics compared to males, including smaller aneurysm diameters (58 ± 7.2 vs. 64 ± 13.2 mm, P < 0.001), more involved aneurysm extent (21.7% vs. 9.8% thoracoabdominal, P = 0.04), increased renal artery calcification (43.9% vs. 27.1%, P = 0.01), and smaller iliac (7.6 ± 1.3 vs. 8.9 ± 1.8 mm, P < 0.01). Operative outcomes were similar; however, females had a greater need for adjunctive access conduits (21.1% vs. 10.6%, P = 0.04), lower technical success (91.2% vs. 98.3%, P = 0.02), and longer median [interquartile range] length of stay (3.0 [4.0] vs. 2.0 [2.5] days, P < 0.001). The composite 30-day outcome of any MAE, new dialysis, or death was not significantly different (15.8% females vs. 11.4% males, P = 0.37). Technical endpoints including 30-day rates of target artery occlusion and type 1 or 3 endoleak were also similar between groups. At mean follow-up of nearly 3 years, females had significantly lower rate of renal function decline (16.0% vs. 41.9%, P < 0.001), but no differences were found in long-term all-cause mortality, aneurysm sac regression, reintervention, or total follow-up imaging studies between groups. Conclusions: Females undergoing complex EVAR had challenging anatomy with higher intraoperative target artery occlusion, conduit use, and longer length of stay. However, 30-day and long-term outcomes were similar, suggesting females can undergo complex EVAR with high technical success and comparable perioperative outcomes to males. Females appeared to have protection from long-term renal function decline, which will be important for future study. (Copyright © 2024 Elsevier Inc. All rights reserved.)
