摘要 目的:应用彩色多普勒检测正常妊娠和胎儿宫内发育迟缓(IUGR)的脐动脉和大脑中动脉血流阻力指数PI、RI值及S/D值,探讨PI、RI及S/D值在IUGR预测中的价值。方法:应用彩色多普勒分别检测了52例正常妊娠(正常组)和IUGR患者(IUGR组)的脐动脉和大脑中动脉的血流,孕28~41周。结果:正常组和IUGR组的脐动脉和大脑中动脉血流指标均随妊娠周数的增高而降低,但IUGR组的脐动脉血流PI、RI、S/D值明显高于正常组(P<0.05)。IUGR组MCA多普勒血流阻力指数RI及S/D明显小于正常组(P<0.05)。孕30周后,脐动脉血流S/D值>4,提示胎儿预后不良。结论:脐动脉及大脑中动脉血流检测可为IUGR诊断提供一定的依据,对胎儿预后的估计有一定的临床价值。
