title: [Giant pseudoaneurysm of the ascending aorta following the aortic valve replacement;report of a case].
abstract: 56-year-old male, who had undergone re-aortic valve replacement (AVR) 33 years ago, received preoperative study for pancreatic surgery. Computed tomography (CT) revealed a giant pseudoaneurysm (7 cm diameter) of the ascending aorta. The ascending aorta was not dilated. A midline skin incision was performed, followed by full sternotomy. A tight pericardial adhesion was carefully dissected. Cardiopulmonary bypass was established by femoral arterial and bicaval venous cannulation. The pseudoaneurysm was incised under the retrograde cardioplegic protection. A communication between ascending aorta and aneurysm was found 1 cm distal to the previous aortic suture line. This communication coincided with the cardioplegic root cannulation site. The aortic prosthetic valve was intact. The ascending aorta was replaced with 26 mm prosthetic graft. Postoperative course was uneventful. In this case, CT was useful to select the approach to the complicated postoperative surgical site.
