彩色多普勒检测妊高征患者胎儿脐动脉血流的应用价值

The Value of Color Doppler Flow Image in Monitoring Fetal Umbilical Artery of the Patients with Pregnancy-induced Hypertension Syndrome

目的:评价脐动脉多普勒血流参数在妊高征(PIN)孕妇中的检测价值及对围产期胎儿预后的价值。方法:应用彩色多普勒检测126例妊高征孕妇脐动脉血流动力学参数,并随机抽取50例正常孕妇为对照组,进行分析和总结,研究其脐动脉血流收缩末速率和舒张末速率峰值的比值(S/D)、搏动指数(PI)与围产儿之间的关系。结果:妊高征组的S/D值和PI值均高于对照组(P<0.01);妊高征组伴有胎儿宫内发育迟缓(IUGR)者的S/D值和PI值均高于妊高征组不伴有胎儿IUGR者;在妊高征组内S/D≥3者围产儿预后不良发生率明显高于S/D<3者(P<0.05)。结论:妊高征组S/D值和PI值均高于正常妊娠者,S/D值和PI值异常者围产儿预后不良明显增高,因此脐动脉血流分析是了解妊高征胎盘功能、预测围产儿预后敏感而实用的监护手段。

Objective：To evaluate the value of monitoring pregnancy - induced hypertension syndrome （PIH） and predicting the condition of fetal in perinatal period by measuring fatal blood flow velocity kinetic indices of fetal umbilical artery with color Doppler ultrasonography. Methods ： The blood flow velocity of fetal umbilical artery in 126 PIH and 50 normal controls was measured with color Doppler ultrasonography, and systolic/diastolic （S/D） and pulsitive index（PI） were examined. Results： the S/D and PI in PIH were significantly higher than those in the control group. S/D and PI in those with intrauterine growth retardation （IUGR） were higher than those in those without IUGR. at the same time S/D in perinatal period fetal was higher than that in the normal one. Conclusion： S/D and PI in PIH are higher than those in the normal group. So to study the fetal umbilical artery blood flow is very important in evaluating placenta and in calculating foetus.
