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., (Copyright © 2017 Elsevier Inc.

The purpose of this article is to report the feasibility and preliminary results of the treatment of isolated iliac artery aneurysms (IAAs) with Anaconda limbs (Vascutek Ltd., Inchinnan, Renfrewshire, Scotland). A prospective cohort is reported of consecutive IAAs treated by two senior surgeons from May to December 2006. One or more Anaconda limbs were used, and internal iliac arteries were embolized if necessary. Twelve IAAs in 11 patients were treated. The average IAA diameter was 4.3 +/- 1.1 cm, and the average diameter of stent used was 14 +/- 2.5 mm, with an average total length of 97 +/- 25 mm. At a mean follow-up of 12 +/- 4 months, there were no graft-related complications, graft occlusions, or requirements for reintervention. Endovascular treatment for isolated IAAs under local anesthesia using Anaconda limbs is feasible, safe, and effective. However, as with all new technology, longer follow-up data are necessary.
