title: [Pedal bypass surgery in diabetic foot syndrome: indications, technique and outcome].
abstract: Peripheral arterial occlusive disease in the diabetic patients is characterized predominantly by long segmental occlusion of the tibial arteries with patent segments of pedal arteries. Neuropathy and high susceptibility for foot infection explain the dramatically increased risk of major amputation. The pattern of arteriosclerotic disease allows construction of pedal bypasses especially by the use of short autologous vein grafts employing distal origin of the bypass. Indication and performance of the bypass procedure rely on a complete angiographic evaluation of the arterial system of the diseased limb. Besides the dorsalis pedis artery with its major branches as preferentially used recipient vessel, the posterior tibial artery and its plantar branches may be anastomosed. Thus, improved foot perfusion will allow necessary minor amputations with safe wound healing. The use of autologous vein grafts is associated with a high late patency rate of more than 70% and a late limb salvage rate of more than 80%. Pedal artery bypass grafting should routinely be part of the therapeutic strategies in advanced diabetic foot syndrome with critical limb ischemia and impending limb loss.
