A 74-year-old man undergone mitral
valve plasty. After cessation of cardiopulmonary bypass, bleeding
persisted from the cardioplegia injection site and dilatation
of the ascending aorta with discoloration was observed. The diagnosis
of type A aortic dissection extending to the descending aorta
was made by transesophageal echocardiogram. Replacement of the
ascending aorta was performed under deep hypothermic circulatory
arrest. The postoperative course was uneventful. The false lumen
of the aortic arch and descending aorta was thrombosed completely
on postoperative computed tomography. Intraoperative aortic dissection
is a rare but fatal complication of cardiopulmonary bypass. Prompt
recognition and appropriate surgical management are of prime
importance.
