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.
成人动脉导管憩室动脉瘤罕见，目前文献中仅报道了37例。一名18岁男性因胸部X线平片发现异常肿瘤阴影入院。术前通过胸部CT扫描、MRI、超声心动图和血管造影诊断为导管动脉瘤，并经术中发现证实。在该患者中，狭窄的峡部和导管憩室被认为是动脉瘤形成的促成因素。通过后外侧开胸术处理动脉瘤，在部分股-股体外循环下用修剪后的涤纶补片封闭动脉瘤口。术后过程顺利。
