Does gender influence the patency of infrainguinal bypass grafts?

Abstract

Infrainguinal revascularization is an effective method of treatment for femoropopliteal/tibial occlusive diseases. However, these bypass grafts are prone to stenosis. In this retrospective study, the authors investigate the association of gender with patency of infrainguinal bypass grafts. The outcomes for consecutive 375 male and 200 female patients who underwent infrainguinal bypass surgery for arterial occlusive disease are compared, and associations with characteristics of the patients, surgical procedure, and graft stenosis are determined. It is found that several demographic, biochemical, and etiological factors could influence the patency of bypass procedures in different genders. However, infrainguinal arterial reconstruction procedures performed in women have a worse outcome when compared with that in men.
