Abstract
The objective of this study was to describe our institutional experience using iliac branch grafts (IBGs) in aortoiliac aneurysm repair. From October 2009 to November 2014, 31 consecutive patients (all men), mean age of 73.1 years (range, 51-89), underwent IBG implantation. Abdominal aortic aneurysm with common iliac artery involvement (n = 15) and bilateral common iliac artery involvement (n = 16) were indications. Computed tomography was used to evaluate patency and postoperative endoleaks within 1 month of implantation and after 1 year. A total of 32 IBGs were deployed in 31 patients successfully. At 1-month and annual follow-up, 100% of grafts implanted were patent. The mean hospitalization duration was 4 days (range, 1-40), with one death at 30 days due to acute renal failure. Ten type II endoleaks and one type Ib endoleak occurred, with one reintervention performed for the type Ib endoleak and the balance being treated conservatively. Five patients had complications. Nineteen patients complained of claudication, with seven cases being resolved. After IBG deployment, 61% of patients were claudication free. IBG placement has excellent short-term outcomes and potential to limit buttock claudication.
