REVASCULARIZATION OF THE INTERNAL MAMMARY ARTERY AFTER CORONARY-ARTERY BYPASS-GRAFTING

Symptomatic anterior myocardial ischemia as a result of stenosis at th e origin of the left infernal mammary artery developed in a patient wh o underwent prior coronary artery bypass grafting using the left inter nal mammary artery as a conduit. Successful revascularization of the l eft anterior descending coronary artery was achieved using a reversed saphenous vein bypass graft from the left common carotid artery to the proximal internal mammary artery. This approach provided myocardial r evascularization and avoided reoperative median sternotomy.
