AbstractThere are only a few published studies on the association between subclavian steal syndrome and ischemic heart disease. The objective of this report is to evaluate the efficacy of subclavian steno-occlusion treatment in patients with subclavian steal syndrome (SSS) and previous coronary bypass. Over the last 8A years we observed 207 patients who underwent left internal mammary artery-intraventricular artery (LIMA-IVA) bypass graft. Of these, 31 patients were affected by steno-occlusion of the homolateral subclavian artery. Ten patients (group 1) showed latent vertebral-SSS and were pharmacologically treated. Seven patients (group 2) had an intermittent vertebral-SSS; four patients were treated with angioplasty and stent application and three were pharmacologically treated. Fourteen patients (group 3) with complete vertebral-SSS were treated with angioplasty and stent application or carotid-subclavian bypass graft. All patients were followed up every 3 months for a period of 5A years after the diagnosis. The first group of patients showed no angina and no sign of subclavian restenosis. In the second group only two patients, who were affected by angina, showed subclavian restenosis at angiography. In the third group only one patient underwent further angioplasty for restenosis. The results of this study show that the SSS may be an adverse event in patients with a LIMA-IVA bypass graft. Identification of the steal is essential to choose an appropriate therapeutic approach.
