A 71-year-old man presented to our hospital with sudden-onset epigastric pain. He reported a history of undergoing the following operations : aortic valve replacement for aortic regurgitation 11 years earlier and graft replacement of the ascending aorta for acute type A aortic dissection, 1 year earlier. His systolic blood pressure was 70 mmHg, and computed tomography revealed a pseudoaneurysm of the distal anastomosis of the ascending aorta with a connection to the right pulmonary artery. Cardiopulmonary bypass was established with cannulation of the right axillary artery and the right femoral vein, and systemic cooling was initiated before sternotomy. We identified an area showing 3 cm dehiscence at the distal aortic anastomosis after hypothermic circulatory arrest and selective cerebral perfusion. The ascending aorta was replaced as hemiarch replacement, and the defect in the right pulmonary artery was closed with bovine pericardium. The patient's postoperative course was uneventful, and he was transferred to a rehabilitation hospital on the 22nd postoperative day.
