title: [Aneurysm of the diverticulum of the ductus arteriosus].
abstract: Aneurysm of the diverticulum of the ductus arteriosus in adult is rare, with only 37 cases reported so far in the literatures. A 18-year-old male was admitted for abnormal tumor shadow in the scout chest X-ray film. Ductal aneurysm was preoperatively diagnosed by chest CT scan, MRI, UCG, and angiography, and was confirmed by the intraoperative findings. In this patient, narrow isthmus and ductus diverticulum were supposed to be contributing factors for aneurysm formation. The aneurysm was approached through a posterolateral thoracotomy and aneurysmal orifice was closed with a trimmed dacron graft under partial femoro-femoral cardiopulmonary bypass. Postoperative course was uneventful.
