Gender disparities exist in the prognosis of endovascular aneurysm repair (EVAR) for infrarenal abdominal aortic aneurysms, and there is controversy regarding whether female patients derive greater benefits from novel stent graft systems.Methods: Data from patients with infrarenal abdominal aortic aneurysms who underwent endovascular repair at our center between 2014 and 2022 were analyzed. A retrospective, propensity-matched analysis with a 1:3 ratio based on comorbidities and anatomic characteristics of the aneurysm neck was conducted to compare outcomes between genders. The primary endpoint was all-cause mortality, while secondary endpoints included type Ia, Ib, and III endoleaks, type II endoleaks, and reintervention rates.Results: A total of 179 patients (53 females) were included in the matched analysis. The minimum follow-up duration was 12 months, and the maximum was 108 months. No statistically significant differences were observed between females and males in terms of secondary or primary endpoints.After propensity matching based on comorbidities and anatomic parameters of the aneurysm neck, there were no significant differences in long-term outcomes between male and female patients
