[Coronary artery bypass grafting in a patient with right aortic arch associated with retroesophageal anomalous left subclavian artery].

A rare case of coronary artery bypass grafting in a patient with right aortic arch was presented. A 62-year-old man was admitted to our hospital with angina pectoris. Coronary angiography revealed total obstruction of left anterior descending artery and jeopardized collateral from right coronary artery. Aortography disclosed right aortic arch associated with retroesophageal anomalous left subclavian artery. As the symptom of neither the vascular ring nor the subclavian steal syndrome was recognized, left internal thoracic artery along with the saphenous vein was used for bypass conduit. The patient is doing well without any troubles 7 months after the operation. Attention should be made to use left internal thoracic artery in a patient with right aortic arch.
