title: Upper limb ischemia resulting from arterial thromboembolism.
abstract: Acute ischemia of the upper limb is commonly caused by trauma and embolic arterial occlusion. However, primary atherosclerotic thrombosis is found infrequently and concern regarding its incidence, recognition, and treatment prompted a review of our clinical experience. Of 36 patients with acute ischemia of the upper limb, 17 (47.2 per cent) had embolic occlusion, 9 (25 per cent) iatrogenic thrombosis in the brachial artery, and 10 (27.8 per cent) primary arterial thrombosis. Of the total group, noncardiac arterial emboli (two patients) and primary atherosclerotic thrombosis (six patients) accounted for 8 of 36 (22.2 per cent) ischemic limbs. Including 2 additional patients who had atherosclerotic thrombosis associated with trauma, the total number represented 10 of 36 (27.8 per cent). An aggressive approach to the undiagnosed patient with acute ischemia of the upper limb is warranted, including the use of arteriography in most cases. In patients with iatrogenic thrombosis in the brachial artery, we believe that the routine use of intraoperative arteriograms may improve the operative results.
