We report a successful staged repair of anomalous origin of right pulmonary artery from the ascending aorta in a neonate. A two-day-old girl, who suffered from severe circulatory failure, was admitted. In spite of all medical treatment, acidosis and systemic hypotension developed. Right pulmonary artery banding was performed in an emergency procedure, resulting in immediate elevation of systemic blood pressure. Definitive operation was subsequently performed on the 48th day after birth. The right pulmonary artery, which was de-banded and divided from aorta, was anastomosed directly to the pulmonary trunk in a side-to-end manner. The postoperative course was uneventful and the pulmonary artery pressure was within the normal range.

A 70-year-old man receiving neoadjuvant chemotherapy (5FU+CDDP) for esophageal cancer was transferred to our hospital for the treatment of asymptomatic thrombus in the ascending aorta. Enhanced computed tomography revealed a low-density mass of 34×16 mm in diameter on the posterior surface of the ascending aorta. We performed thrombectomy and suture plication of the aortic intima under hypothermic circulatory arrest. Intraoperative epiaortic echo showed the mass was floating in the aorta. The patient was discharged from the hospital on the 18th postoperative day. Most patients with aortic thrombus are diagnosed under conditions of peripheral embolism. Asymptomatic thrombus in the ascending aorta is extremely rare. We herein report a case of thrombectomy for asymptomatic thrombus in the ascending aorta.
