Blood flow velocity investigations by applying Doppler method have emerged as a useful tool in obstetrics and gynaecology. The final role of the method is still to be established. Thus far, the umbilical artery Doppler indices have been preferred to the utero-placental indices. We have analysed the Doppler indices from the main branch of uterine artery in 280 women with singleton pregnancy in the third trimester. While fetal blood flow velocities in the cerebral arteries or in the umbilical artery are still unchanged, the increase in the uterine artery resistance may serve as an early indicator of the increased risk to the fetus.
应用多普勒方法进行血流速度研究已成为妇产科领域的一种有用工具。该方法的最终作用仍有待确定。到目前为止，脐动脉多普勒指标比子宫 - 胎盘指标更受青睐。我们分析了280名单胎妊娠晚期妇女子宫动脉主要分支的多普勒指标。当胎儿脑动脉或脐动脉的血流速度仍未改变时，子宫动脉阻力增加可能是胎儿风险增加的早期指标。
