摘　　要：目的:分析三维能量多普勒超声检查妊娠中期胎盘体积及血管指数对再发子痫前期(PE)的预测价值。方法:选取本院产科妊娠16~20周有PE史孕妇,应用三维能量多普勒超声检查胎盘体积及血管指数,比较再发子痫前期组(RPE)与未再发子痫前期组(NRPE)胎盘体积(V)、胎盘血管指数(VI)、血流指数(FI)及血管血流指数(VFI)差异,分析胎盘血管指数对RPE的预测效能。结果:NRPE组与RPE组比较,胎盘VI、FI、VFI有差异(P<0.001),胎盘V无差异(P>0.05);RPE重度组与RPE非重度组胎盘VFI有差异(P<0.05),胎盘V、VI、FI无差异(P>0.05);FI、VFI与RPE存在负相关关系(P<0.05),VI与RPE无相关性(P>0.05),VI、FI、VFI与RPE重度无相关性(P>0.05)。VFI对RPE具有预测效能(P<0.001),敏感度83.1%,特异性75.6%,截断值6.033;VI、FI对RPE不具有预测效能(P>0.05)。结论:三维能量多普勒超声检查妊娠中期胎盘血管指数可以评估RPE的发生风险。Objective:To analyze the values of placental volume and vascular index measured by three-dimensional energy Doppler ultrasonography for predicting recurrent preeclampsia(PE)of pregnant women during the second trimester of pregnancy.Methods:The pregnant women with a history of PE during 16 to 20 gestational weeks were selected as subjects,and their placental volume and vascular index were examined by three-dimensional energy Doppler ultrasound.The placental volume,placental vascular index(VI),flow index(FI),and vascular flow index(VFI)were compared of women between group A(the women with recurrent preeclampsia(RPE))and group B(the women without RPE).The value of placental vascular index for predicting RPE was analyzed.Results:The values of VI,FI and VFI of women in group B had significant different from those of women in group A(P<0.001),but the placental volume had no significant difference between the two groups(P>0.05).The value of VFI of women with severe PE in group A had significant different from that of women without severe PE in group A(P<0.001),but the placental volume and the values of VI and FI had no significant difference between the women with and without severe.There was a negative correlation between the values of FI and VFI and RPE(P<0.05),while there was no correlation between VI value and RPE(P>0.05).There was no significant correlation between the values of VI,FI and VFI and severe-RPE(P>0.05).The VFI value had predictive efficacy for RPE(P<0.001),which’s sensitivity,specificity,and cutoff value were 83.1%,75.6%,and 6.033,respectively,while the values of VI and FI had no predictive efficacy for RPE(P>0.05).Conclusion:The values of placental volume and vascular index measured by three-dimensional energy Doppler ultrasonography can be used for predicting RPE of pregnant women during the second trimester of pregnancy.
