A Case of Asymptomatic Thrombus in the Ascending Aorta / 日本心臓血管外科学会雑誌

ABSTRACT

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.
