Upper limb ischemia: 20 years experience from a single center

Abstract

The objective of this study was to review a single center's experience of upper limb revascularization over 20 years. All patients undergoing operative or endovascular upper limb revascularization between June 1983 and July 2003 were identified. One hundred eighty-four upper limb revascularization procedures were carried out on 172 patients. Sixty-one patients had a thromboembolic event (35%), 53 patients presented with a traumatic vascular injury (31%), and 29 patients had symptoms of chronic atherosclerotic upper limb ischemia (17%). Fifteen patients had subclavian steal syndrome, eight patients had thoracic outlet compression, and six patients had iatrogenic injuries of the upper limb arteries. Fifty-five thromboembolectomies were performed, 37 under locoregional anesthesia. Ten patients (18.2%) died from cardiopulmonary causes following embolectomy. Fifteen reversed saphenous vein bypass grafts were performed for traumatic damage. Twenty-seven patients had a primary repair, and five required a vein patch. One patient subsequently had an arm amputation, and two patients died. Twelve patients presenting with chronic arm ischemia had a subclavian angioplasty, 12 patients had a proximal bypass, and in 5 patients, stenoses were stented. The mortality in this group was 6.9% (2 of 29). The mortality for upper limb revascularization was 8.7%. Almost all deaths occurred after upper limb embolectomy, and the mortality of this procedure was similar to that of lower limb embolectomy. Deaths were the result of cardiac comorbidity, and this should be actively sought and treated if outcomes are to improve.
