We evaluated the outcome of the retrograde endovascular hypogastric artery preservation (REHAP) technique for the treatment of complex aortoiliac aneurysms (AIAs). Perioperative and long-term outcomes were assessed for 12 patients (mean age 77 years, range 64-86 years) who underwent elective endovascular AIA repair via aortouniiliac endografting and REHAP between January 2004 and January 2011. Preoperative images obtained by computed tomography were used for planning. Postoperative images were obtained one and six months after surgery, and once a year thereafter. Technical success was achieved in all cases. No patients exhibited endoleak related to the endoprosthesis, occlusion of implanted components, hip and/or buttock claudication, or colon or spinal cord ischemia during follow-up. This hybrid procedure illustrates the potential of REHAP in the treatment of AIA cases.
