Background: This study investigates the impact of sex on angioplasty and primary stenting for the treatment of claudicants with femoropopliteal occlusive disease (FPOD)., Methods: Two hundred eighty-seven patients enrolled in the Safety and Effectiveness Study of EverFlex Stent to Treat Symptomatic Femoral-popliteal Atherosclerosis (DURABILITY II) trial (a prospective, nonrandomized, core laboratory audited, and independently adjudicated investigational device exemption trial) were stratified by sex (190 men and 97 women) and reviewed., Results: Women presented with FPOD at an older age than men (71.3 ± 11.2 vs. 65.9 ± 9.9 years; P < 0.001). Men were more likely to be hyperlipidemic (89.5% vs. 79.4%; P = 0.030). No other statistically significant differences were observed with regard to periprocedural comorbidities and demographics. Clinically, women presented more often with severe claudication (64.9% vs. 51.1%; P = 0.033) as compared with men that had more moderate claudication (44.2% vs. 29.9%; P = 0.022). The incidence of rest pain and tissue loss was low and did not vary between sexes. Angiographically, women had smaller reference vessels (4.4 ± 0.8 mm vs. 5.0 ± 0.9 mm; P < 0.001). Longer lesions (91.6 ± 46.8 mm vs. 87.8 ± 43.9 mm) and higher primary (79.0% vs. 76.5%), primary-assisted (90.6% vs. 85.1%), and secondary patency (90.6% vs. 85.7%) rates in women did not achieve statistical significance (P = NS). Mean percent stenosis and occlusion rates were similar between groups, but men were more likely to have severe calcification (47.9% vs. 34.0%; P = 0.020). Inter-Society Consensus for the Management of Peripheral Arterial Disease II classifications were similar between groups. The target lesion revascularization, major adverse event, and mortality rates were similar between groups. At baseline, the absolute claudication distance was 0.29 miles for men, while women only reached 0.14 miles (P < 0.0001). Walking improvement questionnaire scores were also compared; women had significantly lower scores at baseline and at 1 year., Conclusions: Despite presenting with FPOD at a later age, with more severe claudication, a shorter absolute claudication distance, and smaller vessels than men, women achieved equal patency rates using angioplasty and primary stenting with similar target lesion revascularization, major adverse event, and mortality rates. Despite these findings, women subjectively have worse symptoms at baseline and at 1 year., (Copyright © 2014 Elsevier Inc. All rights reserved.)
