title: Angioplasty of subclavian artery stenosis proximal to the vertebral origin.
abstract: Percutaneous transluminal angioplasty was performed in nine patients with symptomatic proximal left subclavian artery stenoses. All cases were technically successful. One significant delayed complication occurred in a patient whose common carotid-to-subclavian artery bypass graft occluded several months after a successful subclavian artery angioplasty with a probable subsequent embolic occlusion of the internal carotid artery. The other patients were asymptomatic after follow-up evaluations of 4-23 months.
