Problems of the diabetic foot are frequent. The magnitude of the clinical picture and morbidity mirrors the severity and complexity of the underlying pathobiology. The three pathogenetic mechanism involved are ischemia, neuropathy and infection. Seldom do these mechanisms work in isolation, rather most foot problems result from a complex interplay among all three. The clinical picture of the diabetic foot reaches from the neuropathic deformity with diminished or absent sensation of pain to limited gangrene or superficial ulcer. The polymicrobial infection leads to extensive tissue destruction (plantarphlegmone) with osteomyelitis. The patients often notes no pain and may become aware of the infection only through the presence of drainage or a foul odor. These infections are usually more extensive than would be predicted by clinical signs and symptoms. These lesions must be debrided and drained promptly and completely. This often requires amputations of one or more toes, combined with an incision along the entire course of the infected track on the plantar or dorsal aspect of the foot. Cultures should be taken from the depth of the wound. Initial treatment should be with broad-spectrum antibiotics, with subsequent adjustment based on culture results. The diabetic foot is a clinical problem that can be solved with a high degree of success when the approached by an interdisciplinary team (specialists in infectious and vascular disease, podiatry and diabetology). Arterial reconstruction should be designed to restore maximum perfusion to the foot. The most effective result can be obtained with infra-inguinal vein bypass with distal anastomosis to the most proximal artery with direct continuity to the ischemic territory. The single most important factor in the achievement of the reduction of amputation is the autologous vein bypass. The overall outcome in the diabetic patient in terms of graft patency and limb salvage is equal to that in the nondiabetic.
