Abstract

Background: The aim of this study is to describe our institutional experience using iliac branch grafts (IBGs) in aortoiliac aneurysm repair.

Methods: From October 2009 to April 2016, 41 consecutive patients (all men), mean age 71.7 years (range 55-87), underwent IBG implantation. Abdominal aortic aneurysm with common iliac artery involvement (n = 21) or bilateral common iliac artery aneurysms (n = 20) were indications. Computed tomography was used to evaluate patency and postoperative endoleaks within 1 month of implantation and after 1 year.

Results: A total of 42 IBGs were deployed in 41 patients successfully. One hundred percent of grafts implanted were patent at 1 month and at annual follow-up. There was 1 mortality at 30 days, due to acute renal failure. Sixteen type II and 1 type Ib endoleaks were found, for which 3 reinterventions were performed and the remainder treated conservatively. Five patients had complications which required reintervention.

Conclusions: IBG placement has excellent short-term outcomes and potential to limit buttock claudication in the treatment of abdominal aortic aneurysms involving the iliac arteries.
