Successful vascular reconstruction. Determinants of disability

Improvements in limb salvage during the last decade are a reflection of advances in angiography, antibiotics and technique. We report a 100 per cent success rate with vascular repair and a 100 per cent disability outcome in extremity injuries. Ten male patients, with a mean age of 27.3 (range 18 to 41) years, sustained trauma to the extremity with vascular injury. The etiology of injury was gunshot wounds (5), blunt trauma (4), and stab wounds (1). Time from injury to vascular repair was a mean of 186 (range 60 to 360) min. Vessels injured included popliteal artery and vein (4), tibial artery and vein (2), subclavian artery and vein (2), and axillary artery (1). Six of the injuries were associated with fracture of the adjacent bone and treated with external skeletal fixation. All patients had an associated nerve injury. Five patients underwent fasciotomy; nine were treated with 500 ml Dextran-40 for 48 hr (each day for 2 days). All patients received cephalosporin antibiotics pre-, intra-, and post-operatively. All patients had successful vascular repair, as identified by Doppler ultrasound (10 patients) and intra-/post-operative arteriography (5 patients). The median follow-up period was 22 (range 18 to 30) months. There were no primary amputations (within 30 days); there were four late amputations (2, no function and foot ulcer; 2, causalgia). The five popliteal/tibial injuries had no dorsiflexion and foot drop, two had no function and leg ulcers; two patients had femoral and sciatic nerve injury at the thigh; and three patients had injuries to the brachial plexus.(ABSTRACT TRUNCATED AT 250 WORDS)
