摘　　要：目的:探讨经阴道三维能量多普勒超声对早期先兆流产预后的评估价值。方法:98例先兆流产患者中,先兆流产且无法继续妊娠的49例患者设为A组,先兆流产但可继续妊娠的49例患者设为B组,另选择早孕正常但要求行人工流产术的患者50例设为C组。3组均予以经阴道三维彩色多普勒检查,并应用三维能量多普勒超声技术扫描患者妊娠黄体血流频谱情况,比较3组检查参数指标。结果:A组、B组患者的妊娠黄体形态以混合型为主,而C组则以低回声团块型为主。3组患者在收缩期峰值流速、黄体血流指数、血管形成指数、血管血流综合指数方面比较,差异有统计学意义(P<0.05)。结论:经阴道三维能量多普勒超声能够通过探查妊娠黄体的血流分布状况准确鉴别诊断正常早孕、先兆流产、难免流产,为预测先兆流产的预后提供大量的影像学信息。Objective:To evaluate the prognostic value of transvaginal three-dimensional power Doppler ultrasound in threatened abortion in early pregnancy.Methods:98 cases of threatened abortion were selected.Among them,49 cases with threatened abortion and unable to continue pregnancy were assigned to group A,49 cases with threatened abortion but able to continue pregnancy to be assigned to group B,and the other cases with normal early pregnancy but requiring artificial abortion were selected in the same period.50 cases were divided into group C.All three groups were examined by transvaginal three-dimensional color Doppler ultrasound,and three-dimensional power Doppler ultrasound was used to scan the blood flow spectrum of the corpus luteum of pregnancy.The parameters of three groups were compared.Results:The morphology of corpus luteum of pregnancy in group A and group B was mainly mixed type,while that in group C was mainly low echo mass type.There were significant differences in peak systolic velocity,corpus luteum blood flow index,angiogenesis index and comprehensive index of blood flow among the three groups(P<0.05).Conclusion:Transvaginal three-dimensional power Doppler ultrasound can accurately differentiate and diagnose normal early pregnancy,threatened abortion and inevitable abortion by detecting the distribution of blood flow in the corpus luteum of pregnancy.It provides lots of imaging information for predicting the prognosis of threatened abortion.
