摘要
目的:分析绒毛膜滋养动脉血流参数的异常改变对先兆流产结局的预测价值。方法:收集2017年1月-2019年5月本院先兆流产孕妇,根据随访结果分为继续妊娠组及难免流产组,另取正常孕妇为对照组,分别通过二维彩色多普勒超声及三维能量多普勒超声检测绒毛膜滋养动脉血流参数。结果:绒毛膜滋养动脉S/D及RI值难免流产组大于对照组及继续妊娠组(P<0.001),继续妊娠组与对照组无差异(P>0.05),绒毛膜滋养动脉PI 3组无差异(P>0.05);难免流产组绒毛膜滋养动脉VI、FI及VFI值小于对照组及继续妊娠组(P<0.001),继续妊娠组FI及VFI值小于对照组(P<0.05),继续妊娠组与对照组VI值比较无差异(P>0.05);绒毛膜滋养动脉RI、FI及VFI对先兆流产结局具有预测能力,其ROC曲线下面积0.7~0.9(P<0.001),S/D、VI对先兆流产结局不具有预测能力(P>0.05)。结论:经阴道多普勒超声检测绒毛膜滋养动脉血流RI、FI及VFI对评估先兆流产结局有一定的参考价值,值得应用。
Objective:To analyze the value of blood flow parameters of chorionic trophoblastic artery by transvaginal Doppler ultrasonography for predicting the outcomes of women with threatened abortion.Methods:The pregnant women with threatened abortion were selected and were divided into group A(women with continuous pregnancy)and group B(women with inevitable abortion)according to the followed up results.In addition,normal pregnant women were selected in group C.The blood flow parameters of the trophoblastic chorionic artery of women in the three groups were examined by transvaginal two and three dimensional color Doppler ultrasound.Results:The values of S/D and RI of the chorionic trophotrophic artery of women in group B were significant higher than those of women in group A and C(P<0.001),but which of women in group A had no significant different from that of women in group C(P>0.05).There was no significant different in the PI value of the chorionic trophotrophic artery of women among the three groups(P>0.05).The values of VI,FI and VFI of the choriotrophotrophic artery of women in group B were significant lower than those of in group A and C(P<0.001).The values of FI and VFI of women in group A were significant lower than those of in group C(P<0.05),but there was no significant different in the VI value of the chorionic trophotrophic artery of women among the three groups(P>0.05).The values of RI,FI and VFI of chorionic trophotrophic artery could predict the outcomes of women with threatened abortion,which’s area under the ROC curve was 0.7-0.9(P<0.001).The values of S/D and VI could not predict the outcomes of threatened abortion(P>0.05).Conclusion:The RI,FI and VFI value of the chorionic trophotrophic artery of pregnant women by transvaginal Doppler ultrasound has some reference value for evaluating the outcomes of women with threatened abortion,which is worthy of application.
