Long-term Results of Femoro-Femoral Crossover Bypass After Endovascular Aortouniiliac Repair of Abdominal Aortic and Aortoiliac Aneurysms

Abstract

Aortouniiliac stent grafts allow the endovascular treatment of complex anatomy aortoiliac aneurysms. The main drawback is the need for femoro-femoral crossover bypass, with its complications and its patency limitations. However, some authors have shown good results of femoro-femoral crossover bypass in aneurysmal disease. In this article, initial and long-term results of our experience in femoro-femoral crossover bypass revascularization after endovascular aortouniiliac stent grafts repair of aortoiliac aneurysms is reported. Prospective collection, intention-to-treat, and retrospective analysis maintained database. Femoro-femoral crossover bypass patency assessment of all patients treated between January 1999 and September 2002, compared patients with or without associated occlusive arterial disease. Urgent indications were excluded. In total of 52 patients, with a mean age 72.6 years, 30.8% of patients were identified with associated occlusive arterial disease. Initial systemic and local, access site, complications were 7.7% and 7.7%, respectively, no early thrombosis or death is reported. Primary patency was 90.9% at 54 months, 66 months assisted primary and secondary patency were 97.7% and 100%, respectively. The 48-month survival rate was 84.2%. No significant differences between patients with or without associated occlusive arterial disease were found. Femoro-femoral crossover bypass after aortouniiliac stent grafts treatment of aortoiliac aneurysms shows excellent initial and long-term patency and low complication rate.
