EARLY COMPLICATIONS OF FEMOROFEMORAL CROSSOVER BYPASS GRAFTS AFTER AORTA UNI-ILIAC ENDOVASCULAR REPAIR OF ABDOMINAL AORTIC-ANEURYSMS

Objective: The following procedures are the 3 main methods of endovasc ular repair (EVR) of abdominal aortic aneurysms (AAA): aorto-aortic by pass grafting, bifurcated bypass grafting, and aorta uni-iliac grafts. The latter method has the potential disadvantage of requiring an extr a anatomic graft tie, a femorofemoral crossover bypass graft) to maint ain contralateral pelvic and limb perfusion. The aim of this study was to assess the complications associated with the femorofemoral crossov er bypass graft after aorta uni-iliac EVR of AAA. Method: A prospectiv e review was conducted of the complications attributable to the femoro femoral crossover bypass graft in 136 patients who underwent EVR of AA A with an aorta uni-iliac device. Results: During a median follow-up o f 7 months (range, 0 to 36 months), 4 patients had superficial wound i nfections that required antibiotic treatment and 2 patients had bypass graft infections. Nine hematomas developed: 7 (5%) groin hematomas (6 in patients with Dacron bypass grafts), 1 scrotal hematoma, and 1 per igraft hematoma. One bypass graft thrombus developed. Conclusion: The femorofemoral crossover bypass graft is a safe and a durable component of EVR of AAA with an aorta uni-iliac device. The results are similar to those with bifurcated devices.
