Abstract
Late acute type A aortic dissection after coronary artery bypass grafting (CABG) is rare, and only a few cases have been published in the literature. It is important to treat cases of living graft during reoperation. We report a successful surgical treatment in a case of late acute type A aortic dissection after CABG. A 68-year-old man underwent a triple CABG (to the left anterior descending artery with left internal thoracic artery, to the left circumflex artery with left radial artery, and to the right coronary artery with right gastroepiploic artery) beating heart procedure using a centrifugal pump and pulmonary assist with closed circuit due to unstable angina pectoris in December 2007 and had presented with sudden anterior chest pain, and was found to have an ascending aortic dissection (type A) on enhanced computed tomography in May, 2009. We performed ascending artery replacement, paying special attention to the living graft performed through a median sternotomy. The postoperative course was uneventful and he was discharged on the 22nd postoperative day.
