[Aortic Root Partial Reconstruction Combined with Intraoperative Aortic Dissection:Report of a Case].

A 73-year-old woman with Valsalva aneurysm and mitral regurgitation was introduced to our department. We performed combined operation including aortic root partial repair and mitral valve repair. After wenning from cardiopulmonary bypass, intraoperative aortic dissection was confirmed by transesophageal echocardiography from the ascending aorta to the descending aorta, entry was near to proximal anastomosis line of the ascending aorta. To avoid heart failure, the ascending aorta wrapping by prothesis graft was performed to protect from urgent rupture postoperative at first stage. According to contrast computed tomography (CT) findings, location of entry was correspond with aortic clamping. We performed partial aortic replacement including innominate artery reconstruction for her at fourth day postoperative for treating aortic dissection at second stage. Postoperative course was uneventful.
