title: An aneurysm at the cannulation site discovered 40 years after cardiac surgery: report of a case.
abstract: We report the successful surgical treatment of a pseudoaneurysm of the ascending aorta in a 45-year-old man who underwent surgical closure of a ventricular septal defect at the age of 5. A computed tomography scan ordered for the investigation of a pulmonary mass happened to detect a pseudoaneurysm (20 mm diameter). The pseudoaneurysm protruded anteriorly from the ascending aorta at the previous aortic cannulation site. The ascending aorta, including the lesion, was replaced with a prosthetic graft uneventfully. The cause of the pseudoaneurysm was considered iatrogenic, since he had no prior history of postoperative mediastinitis or blunt chest trauma. A computed tomography scan is a useful means to detect a mass on the ascending aorta following cardiac surgery, and it provides important information to help define a surgical strategy.
