[Coronary subclavian steal syndrome; report of a case].

A 64-year-old man was admitted to our hospital with chief complaint of chest discomfort. He received coronary artery bypass grafting utilizing the in situ left internal thoracic artery 10 years ago. Coronary and left subclavian artery angiogram revealed coronary subclavian steal syndrome and 90% stenosis in the proximal left subclavin artery. Ultrasonography of neck vessels demonstrated 75% stenosis in the bifurcation of left carotid artery. We performed axilloaxillary artery bypass grafting to avoid brain ischemia. Myocardial thallium scintigraphy on dipyridamole testing after axilloaxillary artery bypass grafting could not detect myocardial ischemia. Axilloaxillary artery bypass grafting was effective for coronary subclavian steal syndrome.
