目的探讨胎儿先天性心脏畸形行二维超声三切面法筛查的可行性及局限性。方法回顾性分析接受检查的120例孕妇(125例胎儿)的临床资料与声像图表现,均予以二维超声三切面法筛查胎儿先天性心脏畸形。结果本组120例孕妇(125例胎儿)中,8例(6.40%)胎儿出现血流和心脏形态异常现象,其中2例单心房,3例三尖瓣闭锁,3例心内膜垫缺损。随访117例胎儿经产前二维超声三切面法筛查未表现心脏畸形正常胎儿出生后情况,漏诊与误诊,各2例;本组胎儿先天性心脏畸形检出率6.40%(8/125),诊断准确率96.58%(113/117)。结论采用二维超声三切面法筛查胎儿先天性心脏畸形可行性比较高,医生操作难度减少,是一种安全可靠的产前诊断初步筛查方法 ,但其同样存在一定局限性。
Objective To investigate the feasibility and limitations of screening two-dimensional ultrasound triad of fetal congenital heart malformations. Methods The clinical data and sonographic findings of 120 pregnant women (125 fetuses) were retrospectively analyzed. Both of them were screened for fetal congenital heart defects by two-dimensional ultrasound tri-section method. Results Among the 120 pregnant women (125 fetuses), 8 cases (6.40%) fetuses had abnormal blood flow and cardiac morphology, including 2 cases of single atrium, 3 cases of tricuspid regurgitation and 3 cases of endocardial cushion defect. A total of 117 fetuses were followed up by prenatal two-dimensional echocardiography. There were 2 cases of normal fetal miscarriage after miscarriage and 2 cases of non-cardiac malformations, respectively. The detection rate of congenital heart malformations in this group was 6.40% (8/125) , Diagnostic accuracy 96.58% (113/117). Conclusion It is feasible and safe to screen prenatal cardiac malformations by using two-dimensional ultrasound tripartite method. It is a safe and reliable prenatal diagnosis screening method, but it also has some limitations.
