彩色多谱勒对IUGR脐动脉血流的检测

Study of umbilical artery blood flow in IUGR by color Doppler ultrasound

目的:应用彩色多谱勒检测正常妊娠和胎儿宫内发育迟缓(以简称IUGR)的脐动脉血流指标PI、RI、S/D值。材料和方法:应用彩色多谱勒检测了200例正常妊娠和111例IUGR的脐动脉血流,孕周从26—41周。结果:正常妊娠组及IUGR组的脐动脉血流指标均随妊娠周数的增高而降低,但IUGR组的脐动脉血流PI、RI、S/D值明显高于正常妊娠组(P<0.01)。孕30周后,脐动脉血流S/D值>4,揭示胎儿预后不良。结论:脐动脉血流检测不仅是胎儿监护的一种方法,而且可作为诊断IUGR的一个指标及对估计胎儿预后有一定的临床价值。

Objective To study of umbilical artery blood flow in normal pregnancies andfetal intrauterine growth retardation (IUGR) by color Doppler ultrasound. Methods Color Doppler ultrasound was used to study PI, RI and S/D oi the umbilical artery blood flow in 200 cases of normal pregnancies and 111 cases of IUGR. Result PI, RI and S/D of the umbilical artery blood flow were higher in IUGR group than that of normal group (P <0. 01). Conclusion Umbilical artery blood flow by color Doppler ultrasound has predictive value for fetal intrauterine growth and has an important clinical value.
