The Impact of Patient Sex on Outcomes after Endovascular Treatment of Aortoiliac Occlusive Disease.

The aim of this study was to explore the effect of patient sex on short-term and long-term outcomes after endovascular treatment for aortoiliac occlusive disease (AIOD). A multicenter retrospective analysis was performed on all patients who underwent iliac artery stenting for AIOD across the 3 participating sites from October 1, 2018 to September 21, 2021. Preoperative clinical, operative, and postoperative data were collected on a dedicated database. Demographics and outcomes were compared between male and female patients and the probability of freedom from amputation and freedom from target lesion reintervention were estimated with the Kaplan-Meier method. Of 574 patients, 346 (60%) were male and 228 (40%) were female. Mean follow-up was 12 months. Female patients were significantly older (69.2 ± 10.2 years vs. 67.8 ± 8.9 years, P = 0.025) and more likely to have Trans-Atlantic Inter-Society Consensus II D disease (P = 0.003). The female cohort had significantly less coronary artery disease (40% vs. 50%, P = 0.013), coronary stenting (14% vs. 21%, P = 0.039), and coronary artery bypass grafting (13% vs. 25%, P < 0.001) than the male cohort, as well as less statin use (69% vs. 80%, P = 0.004). There were no differences in stent type, concomitant open surgery, intraoperative events, or hospital length of stay. For 30-day postoperative complications, female patients had a significantly higher rate of thrombotic acute limb ischemia (2% vs. 0%, P = 0.01), while male patients had a higher rate of amputation (4% vs. 9%, P = 0.048). On mid-term outcomes, there was no difference in freedom from amputation or target lesion reintervention between male and female patients (P = 0.14 and P = 0.32, respectively). Female patients had lower incidence of cardiovascular risk factors but presented with higher Trans-Atlantic Inter-Society Consensus II classification and had higher rates of 30-day thrombotic acute limb ischemia. Male patients were more likely to require amputation within 30 days. Despite no differences in the mid-term, these short-term findings suggest that patient sex may be a relevant consideration in postoperative management and surveillance after endovascular treatment of AIOD.
