The purpose of this article is to describe the technique of endovascular repair of infrarenal abdominal aortic aneurysms (AAA) combined with surgical bypass. Eleven patients (eight men, three women; mean age, 64.6 years) underwent stent-graft repair of AAA using a nonbifurcated Z-stent covered with polyester or polytetrafluoroethylene (PTFE) fabric delivered through a 14F to 20F delivery catheter under fluoroscopic control. The stent-graft was used to bridge the infrarenal aorta and common iliac artery. After embolization of the contralateral common iliac artery using a self-expanding vascular occluder (SEVO), a femoral-femoral bypass was surgically created using a reinforced PTFE graft. Immediate and complete thrombosis of the aneurysm occurred in 7 of 11 patients (74%) after stent-graft, SEVO placement, and surgical bypass. Four patients required secondary interventions to repair endoleaks at the proximal anastomosis (n = 2) or leaks at the site of SEVO deployment (n = 3). One patient required only a nontapered aortic stent-graft and did not require a femoral-femoral bypass. After all endovascular procedures, no patients had back-bleeding into the aneurysm, device migration, microembolization, limb ischemia, or neurological sequelae (mean follow-up, 140 days; range, 50 to 200). All 11 patients had complete thrombosis of the aneurysm at follow-up. A nonbifurcated stent-graft can be used successfully in treating infrarenal AAAs in combination with a surgical femoral-femoral bypass.
