本文就我院1978～1984年体征不典型的动脉导管(简称PDA)以及误诊病例中最后均由手术证实诊断的17例进行分析。当PDA或PDA伴室缺合并肺高压时,因仅有收缩期杂音,易误诊或仅诊断为室缺,而将PDA遗漏。故室缺伴肺高压的病儿如有提示PDA的线索时或其他先心病如室缺合并主动脉瓣脱垂时可产生类似连续性杂音,也易误诊为PDA,均需作主动脉造影加以确诊。 This article from 1978 to 1984 in our hospital atypical ductus arteriosus (referred to as PDA) and misdiagnosed cases were confirmed by surgery in 17 cases were analyzed. When the PDA or PDA with atrial septal defect and pulmonary hypertension, due to only systolic murmur, easily misdiagnosed or only diagnosed as ventricular septal defect, leaving the PDA missing. Therefore, the absence of pulmonary hypertension room for children with clues prompted PDA or other congenital heart disease such as atrial septal aortic valve prolapse can produce a similar continuous murmur, but also easily misdiagnosed as PDA, are required for aortic angiography to be Confirmed.
