完全型肺静脉异位引流产前超声诊断及漏诊分析

The prenatal ultrasound diagnosis and analysis of missing diagnosis of TAPVD

目的:探讨完全型肺静脉异位引流(TAPVC)的产前超声诊断并分析漏诊原因。方法:回顾性分析2014年1月—2016年1月产前系统超声筛查的7例TAPVC胎儿的超声声像图表现,总结其超声心动图特征并分析漏诊原因。结果:产前超声共诊断6例TAPVC,分别为心上型3例,心内型2例,心下型1例,其中2例合并其他心内复杂畸形及心外畸形,6例均引产并尸检证实。漏诊1例,产后外院手术证实为TAPVC(混合型),预后好。结论:由有经验的医生应用高分辨率的彩色多普勒超声诊断仪注意多角度、多切面动态观察肺静脉回流情况,能显著提高TAPVC的产前超声诊断率,减少漏诊。

Objective ： To explore the prenatal ultrasound diagnosis and to analyze the reasons of missing d!agnosis of total anomalous pulmonary venous connection. Methods ： To analyze the ultrasonography of 7 eases reviewed by prenatal ultrasound screening in hospital during January 2014 to January 2016, and then to summarize the characteristic and analyze the reasons of missing diagnosis. Results ：There are 3 supra -cardiac pattern ,2 intraeardiac pattern and a infracardiac pattern in the 6 cases of TAPVC discovered by the prenatal ultrasound diagnosis. There are 2 cases were associated with other malformation in the 6 cases. There was one misdiagnosis that confirmed after operation. Conclusion：It can significantly increase the diagnosis rate of the TAPVCT by prenatal ultrasound diagnosis of experienced doctors.
