Arterial reconstruction in the upper extremities

Arterial reconstruction in the upper extremities is rare relative to the incidence of reconstruction in the lower extremities. Twenty-three patients who underwent vascular reconstruction in the upper extremities from 1985 to 2000 were retrospectively reviewed. Atherosclerosis was observed in only two subclavian arteries. The most common cause of occlusion was thromboembolism from the heart, which occurred often in the brachial artery and could be treated successfully with thrombectomy. Seven of eight bypass grafts, including three procedures below the elbow, remained patent during follow-up periods ranging from 2 to 9 years. Arterial reconstruction of the upper extremities differs from that in the lower extremities. Atherosclerosis is a rare cause of ischemia, and the etiology varies with the site of obstruction. Bypass surgery below the elbow is feasible and successful in selected patients. Ischemia of the upper extremity causes significant morbidity and should be treated aggressively whenever possible.
