[Coronary artery bypass grafting in a patient with right aortic arch; report of a case].

A 60-year-old man was admitted to another hospital because of chest oppression on effort. Chest X-ray showed radiographic evidence of a right aortic arch and double vessel coronary artery disease with 50% stenosis in the left main trunk was diagnosed by coronary angiography. He was transferred to our institute for surgical treatment of angina pectoris. Preoperatively, multi-detector row computed tomography (CT) was performed and it revealed a right aortic arch and an aberrant left subclavian artery with narrow left internal thoracic artery. A right internal thoracic artery was well demonstrated. Therefore, conventional coronary artery bypass grafting using a right internal thoracic artery and a saphenous vein graft was performed and his postoperative course was uneventful.
