Direct revascularization for the treatment of forearm and hand ischemia

During an 8-year period, 65 patients underwent operation for ischemia of the arm and hand. Fifty-four patients presented with an acutely ischemic extremity. Twenty-two had cardiac origin emboli, 9 had arterial-arterial emboli, 8 had traumatic occlusion of the brachial artery, and 15 patients developed arterial insufficiency after iatrogenic intervention. Twenty-one of 22 patients with cardiac emboli were successfully treated with embolectomy alone. The majority of patients with arterial-arterial emboli and traumatic or iatrogenic injuries required arterial reconstruction in addition to clot retrieval. After operation, 53 of 54 patients were asymptomatic. Eleven patients underwent operation for chronic ischemia. Seven patients had axillo-brachial saphenous vein grafts, two had carotid-subclavian bypass grafts, and two patients underwent aorto-innominate bypass. All grafts remained patent during follow-up that ranged from 6 months to 8 years. We conclude that operative therapy is very effective in preventing limb loss and functional impairment in patients with acute or chronic upper extremity ischemia.
