title: [Percutaneous transluminal angioplasty in patients with subclavian stenosis and internal mammary grafts].
abstract: Subclavian artery stenosis is an uncommon cause of myocardial ischaemia in patients with internal mammary artery grafts. Coronary subclavian steal and impaired flow through the graft are the two mechanisms implied. We report 2 patients with mammary artery grafts in whom reappraisal of anginal symptoms was related to the presence of proximal subclavian stenoses located just before the origin of the mammary artery grafts. Both patients were successfully treated by percutaneous angioplasty and stent implantation.
