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.

Limb salvage surgery in end stage renal disease: is it worthwhile?

The role of limb salvage surgery in patients with end stage renal disease (ESRD) is controversial. In view of this debate, we reviewed our experience with 54 primary and 15 secondary revascularizations for limb salvage in patients with ESRD over the past decade. Thirty-seven patients required dialysis and 10 had functioning renal transplants. Severe limb threatening ischemia was the indication for all revascularizations. The 2-year cumulative secondary graft patency rate was 56.2% with an associated limb salvage rate of 71.4%. There was no significant difference in graft patency or limb salvage rates between patients requiring dialysis and those with functioning renal allografts (p = 0.5). The 30-day operative mortality for the 99 surgical procedures (69 arterial bypasses and 30 additional operations) was 13% and the 2-year patient survival was 45.6%. Six of the 15 amputations were performed despite a patent graft on limbs which had extensive infection and gangrene. We conclude that limb salvage surgery should only be undertaken with recognition of these risks in patients with ESRD or functioning renal transplants. Surgery should be performed before gangrene and infection become extensive. Patients with unrelenting infection or mid-forefoot gangrene should be considered for primary amputation.
