Utility and reliability of endovascular aortouniiliac with femorofemoral crossover graft for aortoiliac aneurysmal disease

Objective: The purpose of this study was to determine the early efficacy of endovascular aortouniiliac stent grafts with femorofemoral bypass graft in the treatment of aortoiliac aneurysmal disease. Methods: We analyzed 51 consecutive patients from January 1997 to March 199 9 with a mean follow-up of 15.8 months. Patients ranged in age from 44 to 9 3 years (mean, 75 years) with a mean aortic aneurysm diameter of 6.2 cm. Te chnical success was achieved in 50 patients; one patient required conversio n to open repair intraoperatively. We placed 28 custom-made and 22 commerci al devices. The mean operative time was 223 minutes. The endograft was exte nded to the external iliac artery in 42% of cases. The contralateral common iliac artery was occluded using either a dosed covered stent or intralumin al coils. Results: The median hospital stay was 4 days with an average intensive care unit stay of 0.25 days. There were no operative mortalities. Two patients died during follow-up from unrelated conditions. Endoleaks occurred in 11 p atients (22%); seven patients (14%) required intervention (four catheter ba sed, three operative). Other complications occurred in 38% of patients but were largely remote or wound related. One femorofemoral bypass graft occlud ed immediately postoperatively as a result of an intraprocedural external i liac dissection yielding a 98% primary patency and 100% secondary patency. Clinical success was achieved in 88% of patients. Conclusions: These data suggest that this strategy represents a reliable me thod of repair of aortoiliac aneurysmal disease and extends the capability of an endoluminal approach to patients with complex iliac anatomy.
