摘　　要：目的:应用多普勒超声检测子宫动脉、螺旋动脉血流动力学参数,探讨其对妊高征的预测价值。方法:多普勒超声检测206例孕23～26周孕妇子宫动脉、螺旋动脉的搏动指数(PI)、阻力指数(RI)、收缩期与舒张期流速比(S/D)、舒张早期双侧切迹等血流动力学参数,随访至妊娠终止,观察参数变化与妊高征发生之间的关系。结果:206例孕妇中34例发生轻中度妊高征,13例发生重度妊高征。妊高征组子宫动脉、螺旋动脉多普勒参数高于正常组,且重度妊高征组子宫动脉参数高于轻中度组,差异均有统计学意义(P<0.05)。结论:子宫动脉、螺旋动脉多普勒参数对妊高征具有很好的预测价值。Objective To investigate the value of Doppler flow imaging on uterine artery and spiral artery for prediction of pregnancy-induced hypertension syndrome(PIH).Methods Totally 206 pregnant women at 23~26 weeks' gestation were selected,then the hemodynamic parameters of uterine artery and spiral artery including pulsatility index(PI),resistent index(RI),systolic to diastolic velocity ratios(S/D),early diastolic notch were determined by Doppler ultrasound.All the cases were follow-up to termination of pregnancy.The relationship between parameters change and incidence of PIH were observed.Results Finally,34 cases of slight and moderate PIH and 13 cases of severity PIH were observed in 206 pregnant women till the end of follow-up.The hemodynamic parameters of uterine artery and spiral artery in PIH cases were significantly higer than those of normal cases,and the hemodynamic parameters of severity PIH patients were significantly higher than those of slight and moderate PIH patients(all P<0.05).Conclusion The hemodynamic parameters including PI,RI,S/D and early diastolic notch of uterine artery and spiral artery may be helpful for prediction of PIH in clinical.
