Pedal arterial bypass for limb salvage in patients with diabetes mellitus

Abstract

Objective: To evaluate pedal bypass grafting in patients with diabetes mellitus with critical limb ischaemia. Patients and Method: from 1994 to 1999, 49 consecutive pedal bypass grafts were performed in 46 patients with a median age of 69 years (range 37-85 years). The incidence of insulin-dependent diabetes mellitus was 87%. The distal anastomosis was located at the dorsalis pedis artery in 36, at the inframalleolar posterior tibial artery in 9 and at the plantar artery in 4 cases, respectively. Results: One patient died perioperatively. Two bypass occlusions and one major amputation accounted for a primary patency rate of 96% and a limb salvage rate of 98% at 30 days, respectively. During a median follow-up of 28 months (range 1-70 months), 21 patients died of nonrelated causes. Three additional graft occlusions and 4 major amputations were noted, resulting in a primary patency rate of 89% and a limb salvage rate of 87% at 48 months, respectively. Conclusion: Pedal bypass grafting utilising the greater saphenous vein with in-situ technique is a reliable and effective procedure to achieve durable limb salvage in patients with diabetes mellitus. © 2002 Elsevier Science Ltd.
