超声心动图在产前诊断胎儿先天性心脏病中的临床探讨

Study the Clinical Value of Echocardiography for Prenatal Diagnosis of Fetal Congenital Heart Disease

目的:观察超声心动图在胎儿先天性心脏病中的产前诊断价值。方法:选取2010年6月至2011年7月在我院行产前检查的孕周为20-24周的8481例孕妇的胎儿心脏行超声心动图检查,观察超声心动图对胎儿先天性心脏病的诊断准确性,并在出生后对新生儿进行随访追踪,以便进行验证。结果:8481例孕产妇经超声心动图检查后怀疑有67例患有胎儿先天性心脏病,发病率为0.79%;术后及随访确诊的有66例,准确率为98.51%;1例胎儿发生误诊,误诊率为1.49%,漏诊5例,漏诊率0.58%。结论:超声心动图在产前诊断胎儿先天性心脏病具有较高准确率,对在产前进行胎儿先天性心脏病的筛查具有重要意义,值得临床上应用。

Objective： To observe the prenatal diagnosis of echocardiography on fetal congenital heart disease. Method： 8481 pregnant women of antenatal screening by echocardiography examination with gesta- tional 20-24 weeks were selected from 2010 June to 2011 July in our hospital, The diagnosis accuracy were observed , and neonatal were follow-up track after birth , in order to verify. Result： 67patients were suspected as congenital heart disease in 8481cases by echocardiography examination, the incidence was 0. 79% ; 66 cases were confirmed postoperative and follow-up, the accurate rate was 98.51% ;1 case of fetal misdiagnosis was occured, the misdiagnosis rate was 1.49% ,5 cases were missed diagnosis, misdiagnosis rate was 0.58%. Conclusion： Echocardiography has high accuracy in prenatal diagnosis of fetal congenital heart disease , the screening have important value for antenatal fetal congenital heart disease, worthy of clinical application.
