Stent-graft repair of aorto-iliac occlusive disease coexisting with common femoral artery disease

PURPOSE: Significant disease or occlusion of the common femoral artery may preclude percutaneous therapy for aorto-iliac occlusive disease, In addition, aorto-iliac angioplasty may not reverse the ischemic symptoms when common femoral artery disease exists, The authors describe the feasibility of endoluminal stent-grafts to treat multilevel aortoiliofemoral occlusive disease. MATERIALS AND METHODS: The authors placed 18 stent-grafts for aorto-iliac occlusive disease in 17 patients with limb-threatening ischemia and significant common femoral artery disease, These procedures were performed as a joint effort between vascular surgery and interventional radiology staff in the operating room, The common femoral artery was occluded in 10 or severely diseased in eight, necessitating endoluminal bypass to the superficial femoral or popliteal artery (n = 7) or to the deep femoral artery (n = 7), or necessitating patch angioplasty of the common femoral artery (n = 4), Stent-grafts were fabricated from 6-mm polytetrafluoroethylene and 29-mm Palmaz stents. RESULTS: All 18 grafts were placed successfully. Follow-up ranged from 3 to 38 months (mean, 21 months), Seven patients died of myocardial infarction; two grafts occluded and one required angioplasty during follow-up, resulting in a primary patency rate of 81% at 2 years. CONCLUSION: Endoluminal stent-graft placement is a useful method of treatment for advanced atherosclerotic aorto-iliac disease, particularly in the presence of common femoral artery disease, This approach avoids an extra-anatomic bypass or a major transabdominal aortic bypass procedure, Longer follow-up with a larger series is needed to ensure the safety and late graft patency comparable to the traditional aortofemoral and iliofemoral bypass grafts.
