A safe approach to the treatment of iliac artery aneurysms. Aortobifemoral bypass grafting with exclusion of the aneurysm.

Aneurysms of the iliac arterial system are often difficult to approach surgically. Aortobifemoral (ABF) bypass grafting with exclusion of the aneurysms can be used as an alternative to the usually recommended approach of endoaneurysmorrhaphy. Fourteen patients with iliac artery aneurysms treated by ABF are compared to 16 patients treated by direct repair to compare the incidence of complications related to decreased pelvic blood flow or to the presence of the excluded iliac artery aneurysm. There were no differences between the two groups. Therefore, it is concluded that ABF is a reasonable alternative in the treatment of iliac artery aneurysms.
