Angioplasty and stenting for total symptomatic atherosclerotic occlusion of the subclavian or innominate arteries

Abstract

Bypass grafting is considered the treatment of choice for occlusions of supraaortic vessels. Percutaneous transluminal angioplasty (PTA) is a well-established treatment for patients with subclavian stenosis, but its efficacy in total subclavian or innominate occlusions is so far not well established. Since 1995, we have carried out 9 PTA revascularizations in 9 patients with total symptomatic atherosclerotic occlusion of supraaortic vessels. The technical success rate was 100%, without any major (death or stroke) or minor complications. In the follow-up period (mean 37.4 months), 1 patient had a symptomatic left internal carotid artery occlusion and an asymptomatic occlusion of the treated subclavian artery. In expert hands, stenting-PTA should be considered as the primary therapeutic option.
