A 43-year-old male, who had undergone coronary artery bypass grafting 11 years ago, developed exertional chest pain. Selective coronary angiograms revealed severe stenosis and a large aneurysm in the obtuse marginal branch of the circumflex coronary artery. Previous grafts to the left anterior descending coronary artery and diagonal branch were patent. Ligation of the aneurysm and internal mammary artery grafting were performed through a left anterolateral thoracotomy. This approach made it easy to reach the aneurysm and to minimize bleeding during dissecting the adhesions. The patient had an uncomplicated postoperative course, and postoperative coronary angiograms revealed an obstructed aneurysm and a patient internal mammary artery graft. He has done well without recurrence of symptoms.
