A pseudoaneurysm of the thoracic aorta after cardiac surgery is a rare complication, but can be life-threatening when it is ruptured. The pseudoaneurysm itself presents no symptoms in many cases, or may be similar to an atherosclerotic aortic aneurysm. Therefore, it is usually found incidently during imaging studies. We encountered 3 cases of pseudoaneurysm of the thoracic aorta that developed during the long-term follow-up after congenital cardiac surgery. None of the patients experienced specific symptoms associated with the pseudoaneurysm, and were diagnosed by chest roentgenograms and computed tomography. Most patients who undergo surgery for congenital heart defects as adolescents are free from medical treatment, and do not regularly see a doctor after the surgery. It is important to consider the possibility of a pseudoaneurysm in patients having a history of cardiac surgery.
