Abstract

As endografting technology advances, anatomical constraints limiting access and deployment have become less of a burden. While unsuitable candidates for endografting exist, these patients are becoming less frequent. To broaden the applicability of endovascular abdominal aortic aneurysm repair (EVAR), we have modified the bifurcated AneuRx™ device into a unilimb modular prosthesis, by placing an aortic extender cuff across the flow divider, thus excluding its contralateral limb. This technique was used with success in 3 groups of patients: with occlusion of 1 iliac artery, with a nontraversable iliac stenosis, or with a small calcific aortic bifurcation. In these patients, anatomy can make it difficult, if not impossible, to place a bifurcated stent graft. Whether as a planned preoperative procedure or as a "bail-out" maneuver, this procedure has been successful in avoiding open surgical conversion.
