中孕期利用三维能量多普勒检测胎盘体积及相关血流参数对妊高症的预测价值

The predictive value of placental volume and related blood flow parameters in pregnancy-induced hypertension during second trimester by three-dimensional energy Doppler

目的探析中孕期利用三维能量多普勒检测胎盘体积及相关血流参数对妊娠期高血压的预测价值。方法选择68例中孕期产妇,依据有无妊娠期高血压及严重程度分为正常组30例,轻度子痫前期组29例,重度子痫前期组9例。三组均行三维能量多普勒超声检查。对三组各项指标进行比较。结果轻度子痫前期组、重度子痫前期组子宫动脉的收缩末期峰值/舒张末期峰值均高于正常组;正常组与轻度子痫前期组、重度子痫前期组的胎盘血管化指数、血流指数和血管化血流指数均呈降低趋势,子宫动脉的搏动指数呈升高的趋势,且各组间进行比较,差异有统计学意义(P<0.05)。结论三维能量多普勒超声检查能够通过评估分析胎盘体积、血流参数以及胎盘供血指标,从而明确中孕期产妇妊高症情况。

Objective To explore the value of placental volume and related blood flow parameters in pregnancy-induced hypertension during second trimester by three-dimensional energy Doppler.Methods 68 pregnant women in the second trimester were selected.The patients were divided into normal group(n=30),mild preeclampsia group(n=29)and severe preeclampsia group(n=9)according to whether or not they had pregnancy-induced hypertension and the degree of pregnancy-induced hypertension.Three-dimensional energy Doppler ultrasound examination was performed in all groups.The indexes of the three groups were compared.Results The end-systolic/end-diastolic peaks of uterine arteries in mild preeclampsia group and severe preeclampsia group were higher than those in normal group.The placental vascularization index,blood flow index and vascularization blood flow index of normal group,mild preeclampsia group and severe preeclampsia group showed a trend of decrease,while the pulsatile index of uterine artery showed a trend of increase,and the differences among the groups were statistically significant(P<0.05).Conclusion Three-dimensional energy Doppler ultrasound can evaluate and analyze the placental volume,blood flow parameters and placental blood supply indicators,so as to clarify the situation of pregnancy-induced hypertension in the second trimester.
