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56岁男性患者，其因误诊的动脉导管未闭（patent ductus arteriosus）、重度多瓣膜病变及活动性主动脉瓣心内膜炎继发巨大肺动脉瘤，经手术治疗后成功康复。尽管术前已开展相关检查，但仍未能作出正确诊断，究其原因在于该细小动脉导管未闭位于肺动脉干远端，且巨大反流信号掩盖了其多普勒信号。无论患者年龄如何，均需对其进行全面评估，以识别并治疗该先天性畸形。
