Aneurysm of the ductus arterious in adult in rare. 28 cases have been previously reported in the Japanese literature. A new 73-year-old male case, preoperatively diagnosed and successfully repaired, are presented. The patient with hoarseness was admitted to our hospital. Contrast-enhanced CT scans and aortograms made a diagnosis for the aneurysm of the ductus arteriosus. Operation was done through left thoracotomy with the aid of partial cardiopulmonary bypass. The pulmonary arterial end of the ductus arteriosus was closed and a Ligamentum arteriosus was identified. A 3 by 2.7 cm saccular aneurysm was resected and segmental replacement of the aorta with woven dacron graft was performed. Because of it's critical location and the high incidence of complications, aneurysm of the ductus arteriosus in the adult should be surgically corrected when diagnosed.
成人动脉导管瘤罕见。日本文献此前已报道28例。本文介绍1例新的73岁男性病例，术前诊断并成功修复。该患者因声音嘶哑入院。增强CT扫描和主动脉造影诊断为动脉导管瘤。在部分体外循环辅助下经左胸切口进行手术。封闭动脉导管的肺动脉端并辨认出动脉韧带。切除一个3×2.7厘米的囊状动脉瘤，并用编织涤纶人工血管对主动脉进行节段性置换。由于其位置关键且并发症发生率高，成人动脉导管瘤一旦诊断应行手术矫正。
