彩超筛查对诊断中孕期胎儿心脏畸形的的应用及价值

Ultrasound Screening in the Application and Value of Diagnosis of Fetal Cardiac Mmalformations

目的探讨彩超筛查作为产前诊断胎儿心脏畸形常规检查方法的应用及价值。方法回顾性分析2010年7月~2013年12月在我院做过彩色多普勒超声筛查(胎龄20~28w)共6000例。其中住院分娩或引产解剖或随访确诊胎儿心脏畸形37例。现对确诊胎儿心脏畸形的37例胎儿心脏声图象进行分析、统计、总结。结果37例胎儿心脏畸形中被彩超筛查检出且准确者33例,诊断符合率85.9豫,彩超检查出但不符合4例,误诊率10.8豫,未被彩超筛查出2例,漏诊率5.4豫。结论中孕期彩超筛查是产前诊断胎儿心脏畸形的有价值的无创性诊断技术,可以发现胎儿时期严重的心脏畸形,可以大大降低胎儿先心出生率。但由于胎儿先天性心脏病本身的复杂性和超声检查存在的局限性,不可能在产前检出所有的心脏畸形,应向孕妇及家属说明。

Objective To study the application and value of color Doppler ultrasound screening in prenatal diagnosis of fetal cardiac malformations routine examination method.Methods Retrospective analysis of 2010 July to 2013 December in our hospital did color Doppler ultrasound screening(gestational age 20~28 weeks)were 6000 cases.The hospital delivery or induced labor of anatomical or fol ow-up diagnosis of fetal cardiac malformation in 37 cases.This analysis,statistics,summary of the diagnosis of fetal cardiac malformations in 37 cases of fetal heart sound image.Results 33 cases of 37 cases of fetal cardiac malformations detected by ultrasound screening and accurate,diagnosis coincidence rate 85.9%,color Doppler ultrasound examination but do not meet the 4 cases,the misdiagnosis rate was 10.8%,ultrasound screening is not out of 2 cases,the missed diagnosis rate is 5.4%.Conclusion Pregnancy ultrasound screening is a noninvasive diagnostic technique in prenatal diagnosis of fetal cardiac malformations have value,can be found in fetal period serious heart malformation,can greatly reduce the birth rate of fetal congenital heart disease.But due to the limitation of complexity of fetal congenital heart disease itself and the ultrasound examination,is not possible in the prenatal diagnosis of al heart malformation,should explain to the pregnant women and their families.
