目的探讨产前胎儿超声心动图检查方法的临床价值。方法应用彩色多普勒超声诊断仪对510例孕20～40周高危孕妇行产前胎儿超声心动图检查,并将胎儿超声检查与胎儿尸检或分娩后彩色多普勒超声检查结果进行对照。结果胎儿超声心动图510例中,检出异常者71例,结构性心脏异常50例(9.80%),3例未尸检,2例随访丢失,2例生后未见异常,3例漏诊(1例为室间隔缺损,2例为房间隔缺损);非结构性心脏异常21例(4.12%),6例生后未见明显异常。超声心动图检查胎儿异常的敏感度为95.08%,特异度为98.20%,阳性预测值为87.88%,阴性预测值为99.32%。结论胎儿超声心动图检查对胎儿结构性心血管异常的诊断有重要作用,常规胎儿超声心动图的开展可以提高其检出率。
Objective To investigate the clinical value of prenatal fetal echocardiography. Methods Prenatal fetal echocardiography was performed in 510 high-risk pregnancies with gestational age of 20-40 weeks by color Doppler sonography. Fetal sonography was compared with fetal autopsy or color Doppler ultrasonography after childbirth. Results Among the 510 cases of fetal echocardiography, 71 cases were detected abnormalities, 50 cases were structural heart abnormalities (9.80%), 3 cases were not autopsy, 2 cases were lost in follow-up, 2 cases had no abnormalities after birth, 3 cases missed diagnosis Cases of ventricular septal defect, 2 cases of atrial septal defect); non-structural cardiac abnormalities in 21 cases (4.12%), 6 cases no significant abnormalities after birth. The sensitivity and specificity of echocardiography in detecting fetal abnormalities were 95.08%, 98.20%, 87.88%, and 99.32%, respectively. Conclusion Fetal echocardiography plays an important role in the diagnosis of structural cardiovascular abnormalities in fetuses. The routine fetal echocardiography can improve the detection rate.
