INTRODUCTION: @entity439 repair (EVAR) with aortouniiliac prostheses extends the morphologic range of @entity439 that can be treated and is potentially a more rapid and simple operation than bifurcated endovascular repair. It may, however, be limited by durability of the femorofemoral extra-anatomic bypass graft required to revascularize the contralateral lower limb. Previous studies of femorofemoral bypass grafts were performed almost exclusively in @entity1 with @entity432 . An 8-year single center experience with use of the femorofemoral bypass graft in @entity439 is reported. METHODS: All @entity1 undergoing EVAR with an aortouniiliac endovascular stent graft over eight years (1994-2002) at a single institution were included in a retrospective study. @entity1 data were collected from a prospectively maintained local endovascular database. All @entity1 gave informed consent and were part of an endovascular program approved by the local ethics committee. RESULTS: Over the 8 years, 231 @entity1 underwent EVAR with an aortouniiliac endovascular stent-graft. Median follow-up was 22 months. Localized wound complications were observed in 25 @entity1 (11%). Cumulative 3-year patency rate for the femorofemoral bypass graft was 91%. At the end of 5 years 83% of grafts remained patent. CONCLUSIONS: The femorofemoral bypass graft used during EVAR with aortouniliac stent grafts offers encouraging medium and long-term patency. When graft occlusion occurs, it is usually directly attributable to inadequate inflow from the endovascular stent graft itself or to endoluminal damage of the external iliac artery. Awareness and early detection of stent-graft distortion or complications in the external iliac artery may result in improved patency rates.
