文摘

Late onset of angina pectoris associated with subclavian artery (SA) atherosclerotic occlusive disease is a rare and recognized cause of myocardial ischemia when the lesion is proximal to a left internal mammary artery (LIMA) to coronary bypass. The symptoms typically exacerbate by increasing the flow demand in the extremity; this phenomenon is known as late coronary–subclavian steal syndrome. We describe the case of a 66-year-old woman who underwent coronary artery bypass grafting from the LIMA to the left anterior descending coronary artery in 2000. Years later, she experienced refractory angina pectoris associated to an occlusive lesion in the proximal left SA. SA endarterectomy with eversion technique and subclavian–carotid transposition restored the antegrade flow with resolution of the symptomatology.
