彩色多普勒超声多切面联合显示法在高危人群产前胎儿心脏筛查中的诊断价值

目的 :探讨彩色多普勒超声多切面联合显示法在高危人群产前胎儿心脏筛查中的诊断价值。方法 :对2 165例具有高危因素的孕妇及2 050例无高危因素的孕妇,在孕20~36周运用多切面联合显示法,在上腹部短轴切面、四腔心切面、左心室流出道切面、右心室流出道切面、三血管/气管、心底短轴切面、主动脉弓切面、动脉导管弓切面、上下腔静脉切面、肺静脉入左心房切面,进行胎儿心脏形态结构检查。结果:产前超声发现心脏异常93例,其中高危人群检出率为2.73%(59/2 165),无高危因素人群检出率为1.66%(34/2 050),差异有统计学意义(P<0.05)。结论:彩色多普勒超声多切面联合显示法是诊断胎儿先天性心脏病的可靠手段,在胎儿先天性心脏畸形的产前诊断方面起到重要作用。

Diagnostic value of multiple plane display-color Doppler echocardiography for screening fetal congenital heart disease in high-risk population

Objective： To investigate the diagnostic value of multiple plane display-color Doppler echocardiography for screening fetal congenital heart disease（CHD）. Methods： A total of 2 165 high-risk pregnant women with 20 to 36-week pregnancy were enrolled, and 2 050 normal pregnant women were taken as controls. Multiple plane display-color Doppler echocardiography was performed, including epigastrium-short view, four-chamber view, LV-outflow view, RV-outflow view, three-vessels/trachea view, heart bottom-short view, aortic arch view, ductus arteriosus arch view, vena cava view, pulmonary vein into left atrium view. Results： Ninety-three fetuses were diagnosed as having congenital heart defect,the detection rate in high-risk pregnant women was 2.73%（59/2 165）, and in normal pregnant women was 1.66%（34/2 050）. There was a statistically significant difference in detection rate between the two groups（P 〈0.05）. Conclusions：Multiple plane display-color doppler echocardiography is a reliable method for diagnosing fetal CHD, and can be used for prepartum diagnosis of congenital heart disease.
