彩色多普勒血流图监测胎儿脐动脉血流频谱临床价值

Clinical Value of Coloured Doppler Flow Imaging in Monitoring Blood Flow velocity of Fetal Navel Artery

目的：探讨彩色多普勒监测胎儿脐动脉血流动力学的临床价值。方法：应用彩色多普勒血流显像技术，对５２例不同孕周的胎儿进行血流动力学检测。结果：发现正常妊娠时胎儿脐动脉的搏动指数、阻力指数、收缩期最高峰值血流速度／舒张末期最低血流速度比值随孕龄的增加而下降；胎儿宫内发育迟缓时，孕２２周即出现搏动指数、阻力指数、收缩期最高峰值血流速度／舒张末期最低血流速度比值异常，与正常组相比均有显著或极显著性差异。结论：彩色多普勒血流显像技术检测脐动脉血流是观察胎儿血循环的敏感指标。

objective:To probe into the clinical value of coloured Dopper imaging in monitoring blood flow veloity of fetal navel artery.Method:Using the coloured Doppler imaging technique to detect the fetal hemodynamics of 52 pregnant women in different pregnant stages.Results:PIRI and S/D of fetal artery were found to become low when the pregnant days increased in normal pregnancy.When IUGR occured,PIRI and S/D ratio of fetal artery showed abnormal values from 22th week on,which was significantly different from that in normal pregnancy.Conclusions:The coloured Doppler imaging technique is a sensitive way to detect the fetal circulation and it is also a reliable monitoring method.
