永存动脉干的产前超声心动图表现特点及其鉴别诊断

The diagnositic value and diferential diagnosis in screening fetal persistent truncus arteriosus by prenatal echocardiography

目的分析产前超声心动图在诊断胎儿永存动脉干的临床使用价值,探讨其声像图特点和鉴别诊断,以及合并畸形和检查中注意的问题。方法采用全面、系统的多切面胎儿超声心动图连续扫查法,回顾性分析7例永存动脉干胎儿的产前超声心动图影像学资料。结果产前超声心动图共诊断永存动脉干7例,病理解剖证实永存动脉干6例(1例肺动脉闭锁被误诊为永存动脉干),均合并其他心内畸形。结论产前超声心动图在诊断、鉴别诊断永存动脉干有着很重要的实用价值。

Objective To evalue the feasibility and diagnosis in screening fetal persistent truncus arteriosus by prenatal echocardiography.The sonographic features and accompanied malformations were analyzed retrospectively.Methods The regular planes were observed by prenatal echocardiography.7 patients with truncus arteriosus were found and analyzed.Results We diagnosed 6 cases of fetal persistent truncus arteriosusby autopsy after inducing abortion.One case was misdiagnosed,all of whom accompanied malformations.Conclusion Prenatal echocardiography has very high value in diagnosis of fetal persistenttruncus arteriosus.It needs to be diferential diagnosis with pulmonary artesia.
