Abstract

To evaluate diagnostic investigations, operative management and long-term outcome of atherosclerotic aneurysms of the subclavian artery. A retrospective clinical study through a follow-up period of 68 months (8 months to 11 years). Department of Vascular Surgery, University Hospital. Between 1983 and 1995, 5 patients with atherosclerotic aneurysms of the extrathoracic subclavian artery were reviewed. All patients presented a pulsatile supraclavicular mass. Ultrasonography and angiography confirmed the diagnosis and were useful in planning the operation. Four patients were submitted, through a supraclavicular incision, to resection of the aneurysm and replacement of a prosthetic graft (dacron in 2 cases, PTFE in the remaining 2 cases). In one patient, with a small saccular aneurysm, a tangential aneurysmectomy with a patch angioplasty (PTFE) was performed. All patients recovered after a mean hospital-stay of 9 days and had a valid radial pulsation. During the follow-up period, a dacron graft failure occurred 38 months later in one patient: she remains today asymptomatic. Resection is today recommended for all patients with diagnosed subclavian artery aneurysms. Because of unknown natural history of asymptomatic aneurysms, with a...Continue Reading
