Introduction: Successful endovascular exclusion of abdominal aortic aneurysms is largely dependent on adequate apposition of the stent graft to the aortic wall. Proximal endoleaks at the time of stent graft placement are uncommon but are more prevalent in patients with challenging neck anatomy. If these initial leaks do not respond to simple balloon angioplasty, Palmaz stents (Cordis Endovascular, Warren, NJ) and covered stent graft cuffs both have been used to seal the endoleak. Long-term data regarding the efficacy of one method over the other, however, is lacking.

Methods: We retrospectively reviewed a database of all infrarenal aortic aneurysm repairs with an intraoperatively diagnosed type Ia endoleak requiring Palmaz stent or covered stent graft cuff placement. Fenestrated and branch grafts were excluded. All records and appropriate imaging studies were reviewed. The primary end points were te...
