[A repair of the aortic pseudoaneurysm after ascending aortic grafting in acute type A dissection--a case report].
A postoperative pseudoaneurysm of the ascending aorta is reported. The patient was a 73-year-old female with a history of graft replacement of the ascending aorta for acute type A dissection 5 years ago. She was referred to our hospital because of chest pain. Preoperative radiographic examination revealed a large pseudoaneurysm of the ascending aorta close to the distal anastomotic site of the graft as well as an aneurysm of transverse arch. During surgery, the pseudoaneurysm originated from a intimal defect in the aortic wall 1 cm distal to the suture line. It is suggested that the pseudoaneurysm was caused by a clamp injury during the initial operation. Replacement of the ascending aorta and transverse arch was successfully performed under selective cerebral perfusion. We should keep the clamp injury in mind when we apply an aortic clamp to a fragile dissected aorta.
