Unusual Presentation of Patent Ductus Arteriosus in Elderly Patient

Abstract We presented a case of a 56-year-old man with giant pulmonary artery aneurysm caused by a misdiagnosed patent ductus arteriosus, severe multivalvular disease and active aortic valve endocarditis successfully treated by surgery. The correct diagnosis was missed despite preoperative diagnostics because the small patent ductus arteriosus was located at the distal part of common pulmonary trunk and a huge regurgitant signal overlapped its Doppler signal. Thorough evaluation of every patient, regardless of age, is necessary to recognize and treat this congenital anomaly.

摘要 本文报告1例因误诊动脉导管未闭（patent ductus arteriosus）引发巨大肺动脉动脉瘤、合并重度多瓣膜病变及活动性主动脉瓣心内膜炎的56岁男性患者，经手术治疗后痊愈。尽管术前已完善相关诊断检查，但因细小的动脉导管未闭位于肺动脉干远端，且大量反流信号掩盖了其多普勒信号，最终未能在术前作出正确诊断。本病例提示，无论患者年龄大小，均需对每位患者进行全面评估，以识别并矫治此类先天性心血管畸形。
