[Arterial disease of the lower limbs in diabetic patients].

Lower limb arterial disease in diabetics resembles that in non diabetics. However, some important differences include the vessels involved and the extent of the involvement. In the diabetic, the arteries most frequently involved are those below the knee. Arterial occlusions are bilateral, multisegmental, and involve unusual vessels such as the internal iliac artery, the deep femoral artery, the small branches and the collateral circulation. Arterial disease in the diabetic appears at a younger age, advances more rapidly, is more diffuse, and is almost as common in women as in men. Interaction of arterial disease, neuropathy and infection produces a wide away of clinical findings, including callus formation, foot ulcers, cellulitis, osteomyelitis and patchy areas of gangrene. Foot abscess and cellulitis require emergency debridement and drainage. Arterial reconstruction, including endovascular procedures, lessen the rate of amputation, allow partial foot amputation, and prevent from recurrent foot ulcer. Soft tissue repair, and especially fasciocutaneous flaps or musculocutaneous flaps, provide the means to heal most of the patients without infection, and avoid below-knee amputation.
