目的:探讨分析产前彩色多普勒超声检查在胎儿先天性心脏病诊断中的应用。方法:选取2002年1月～2011年5月于我院进行B超检查孕周在20～34周1.1万名孕妇为对象,用彩色多普勒超声结合胎儿心电记录技术,观察胎儿心脏四腔观、胎心率/律及胎心各腔血流检测,对诊断明确为先天性心脏病的胎儿进行随访,引产者予以尸解,分娩者予以彩超复查。结果:本组1.1万例孕妇中共检查出先天性心脏病53例,检出率为4.82‰。这其中引产尸解证实有18例,产后超声复查证实35例,53例产前均发现心腔异常血流,其中发现心脏四腔观异常声像图48例,发现率达到90.6%。另外,发现心律不齐的有124例,1例出现四腔异常,产前未发现异常的其他胎儿中,产后发现有先天性心脏病3例,发生率为0.27‰。结论:产前彩色多普勒超声检查是发现胎儿先天性心脏病的重要诊断方法,结合心脏四腔观、胎心率/律及胎心各腔血流检测更有利于发现胎儿先天性心脏病。
Objective: To investigate the application of prenatal color Doppler ultrasonography in the diagnosis of fetal congenital heart disease. Methods: From January 2002 to May 2011 in our hospital for B-ultrasound in gestational weeks at 20 to 34 weeks of 11,000 pregnant women as the object, with color Doppler ultrasound and fetal ECG recording to observe the fetal heart four Cavity view, fetal heart rate / heart rate and fetal blood flow in each cavity, the diagnosis of congenital heart disease fetus were followed up, induced abortion were autopsy, childbirth were color Doppler ultrasound. Results: The group of 11,000 pregnant women detected 53 cases of congenital heart disease, the detection rate was 4.82 ‰. Among them, 18 cases of induced abortion were confirmed, 35 cases were confirmed by post-natal ultrasound examination, and abnormal blood flow was found in 53 cases prenatal. Among them, 48 cases were found with four-chamber abnormal sonography, the detection rate was 90.6%. In addition, there were 124 cases of arrhythmia found, 1 case of four-chamber abnormalities, prenatal abnormalities found in other fetuses, postpartum found in 3 cases of congenital heart disease, the incidence was 0.27 ‰. Conclusion: Prenatal color Doppler ultrasonography is an important diagnostic method to detect fetal congenital heart disease. Combined with four-chamber view of heart, fetal heart rate / heart rate and blood flow in each cavity of fetal heart, it is more beneficial to find fetal congenital heart disease .
