Evaluating the Effectiveness of Internal Iliac Artery Branched Endovascular Stent Grafts

Abstract

The aim of this study is to describe our institutional experience using iliac branch grafts (IBGs) in aortoiliac aneurysm repair. From October 2009 to April 2016, 41 consecutive patients (all men), mean age 71.7years (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. 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 30days, 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. IBG placement has excellent short-term outcomes and potential to limit buttock claudication in the treatment of abdominal aortic aneurysms involving the iliac arteries.
