Abstract
Background This article presents an endovascular approach to repair a unilateral or bilateral aortoiliac aneurysm with a bifurcated iliac limb that can maintain perfusion to the internal iliac artery (IIA) bilaterally through a brachial access. Methods A standard infrarenal aortic aneurysm repair is performed followed by iliac aneurysm exclusion. To obtain exclusion in the common iliac artery aneurysm, a bifurcated Endurant iliac limb is modified to compartmentalize iliac flow 2-3 cm above the internal iliac ostia. Then, a balloon-expandable covered stent graft is used to achieve sealing in the IIA and external iliac artery (EIA). The IIA is stented from the arm and the EIA is stented from the groin. Results There was no in-hospital or 30-day mortality. The procedural design was followed in each of the patients who received treatment. Technical success was 100%, short-term clinical success was 92%, and midterm clinical success was 83%. Average dosage of contrast medium was 116 mL (range, 55-193 mL), and average fluoroscopy time was 42.1 min (range, 20.8-91.6 min). Average length of hospital stay was 2.6 days (range, 1-9 days). There was 1 recorded endoleak. No reports of gluteal claudication, sexual dysfunction, or bowel or spinal claudication have been found. Conclusions The technique described here does not require an up-and-over approach, allowing simplified bilateral repair. Although this is a promising technique, long-term durability needs to be evaluated in a controlled prospective study. © 2015 The Authors. Published by Elsevier Inc.
