目的 :探析高危妊娠子宫螺旋动脉血参数测定中应用彩色多普勒超声检查的临床价值。方法 :入选我院2013年4月~2014年3月产前筛查孕妇1000例,均进行彩色多普勒超声检查,评估高危妊娠孕妇(n=150,其中介入超声50例,超声造影100例)与正常孕妇组(n=850)的母体及胎儿的子宫螺旋动脉血参数指标:搏动指数(PI)、阻力指数(RI)、收缩期峰值速度与舒张期末速度比(S/D);评估正常妊娠组及高危妊娠组的围产儿结局情况。结果 :高危妊娠组的孕妇子宫螺旋动脉血流PI、RI、S/D等指标显著高于正常妊娠组,差异有统计学意义;高危妊娠组的胎儿脐动脉血流PI、RI、S/D等指标显著高于对照组,差异有统计学意义;高危妊娠组发生胎儿生长受限、剖宫产率、新生儿呼吸窘迫等情况显著高于正常妊娠组,差异有统计学意义。结论 :对高危妊娠孕妇进行彩色多普勒超声检查评估其子宫螺旋动脉血流动态,有助于预测其妊娠结局,值得临床推广。
Objective: To investigate the clinical value of color Doppler ultrasonography in the determination of uterine spiral arterial blood parameters in high risk pregnancies. Methods: One hundred and ten prenatal screening pregnant women were selected from April 2013 to March 2014 in our hospital. Color Doppler ultrasonography was performed to evaluate the risk of pregnant women (n = 150), including 50 cases of interventional ultrasound and 100 cases of contrast-enhanced ultrasound ) And normal pregnant women (n = 850) maternal and fetal uterine spiral arterial blood parameters index: pulsatility index (PI), resistance index (RI), systolic peak velocity and end diastolic velocity ratio (S / D) Perinatal outcome in normal pregnancy and high risk pregnancy groups. Results: The PI, RI, S / D and other indexes of uterine spiral artery in pregnant women in high risk pregnancy group were significantly higher than those in normal pregnancy group, and the levels of PI, RI, S / D And other indicators were significantly higher than the control group, the difference was statistically significant; high risk pregnancy group fetal growth restriction, cesarean section rate, neonatal respiratory distress and other conditions was significantly higher than the normal pregnancy group, the difference was statistically significant. Conclusion: Color Doppler ultrasonography in pregnant women with high-risk pregnancies can assess the dynamic of blood flow of uterine spiral artery and help predict the outcome of pregnancy. It is worthy of clinical promotion.
