摘　　要：目的:应用彩色多普勒血流显像技术(CDFI)检测胎儿肾动脉血流的搏动指数(PI)、阻力指数(RI)及血流速度峰谷比(S/D),探讨羊水过少胎儿肾动脉血流动力学变化在妊娠晚期的临床意义。方法:对35例羊水过少孕妇和95例正常对照胎儿肾动脉血流的S/D、PI、RI进行产前检测,并追踪分娩结局。结果:羊水过少组与对照组肾动脉的S/D、PI、RI各值较对照组增高,差异有显著性(P<0.01),两组分娩结果中,新生儿Ap-gar评分≤7分的发生率差异无显著性(P>0.05)。羊水过少组因产前胎心监测异常而行剖宫产率较正常组明显增高(P<0.01)。结论:胎儿肾动脉血流动力学变化可作为妊娠晚期羊水过少胎儿宫内安危状况的敏感指标。Objective:Monitoring fatal renal artery(RA)by the technology of color Doppler ultrasonography to study the change and its clinical significance of Renal arterial blood parametes such as blood flow-rate,S/D,PI,RI in late trimester of pregnancy with oligohydramnios.Methods:S/D,PI,RI in 35 gravidas with oligohydramnios and 95 normal gravidas were detected and followed up.Results:The difference were significant in S/D,PI,RI between gravida with oligohydramnios and normal gravida(P<0.01);The difference were significant in the percent of caesarean birth between the two groups(P<0.01);There is no difference in neonate Apgar score(P>0.05).Conclusion:Renal arterial blood parametes is a sensitive marker in detecting amniotic fluid volum and comprehend fetus status in the late trimester of pregnancy.
