经阴道超声检查诊断早孕流产的临床应用价值

Clinical Application Value of Transvaginal Detection in Diagnosis of Early Pregnancy Abortion

目的:探讨经阴道超声检查在孕早期流产诊断中的临床应用。方法:选取2016年1月至2018年1月期间在三亚中心医院进行产前检查的300例孕早期女性纳入研究,均经阴道彩色多普勒超声检查,记录孕妇子宫螺旋动脉、子宫动脉、黄体血流、形态及超声回声等情况,随访早期妊娠结局,对比分析流产女性、先兆流产继续妊娠女性及正常孕早期女性的超声检查结果。结果:在300例孕早期女性中,232例(77.33%)为正常早孕女性,68例(22.67%)出现先兆流产,其中,25例(36.76%)流产,43例(63.24%)继续妊娠。3组子宫螺旋动脉及黄体血流PI值和RI值比较差异均有统计学意义(P <0.05),且流产组高于先兆流产继续妊娠组和正常早孕组。3组不同形状黄体所占比例比较差异有统计学意义(P<0.05),其中,流产组中点形和棒形黄体所占比例最高。流产组黄体大小异常率高于先兆流产继续妊娠组,且差异有统计学意义(P<0.05)。3组黄体超声回声情况比较差异有统计学意义(P<0.05),其中,流产组黄体不均质低回声所占比例最高。结论:经阴道超声监测孕早期女性子宫螺旋动脉、黄体血流及黄体形状、大小、超声回声等情况对孕早期流产具有一定诊断价值。

Objective:To explore the clinical application of transvaginal ultrasonography in the diagnosis of abortion in early pregnancy.Methods:During the period from January 2016 to January 2018,300 pre-pregnancy women who underwent prenatal examinations in our hospital were included in the study.Transvaginal color Doppler ultrasonography was performed to record the uterine spiral artery,uterine artery,corpus luteum blood flow,morphology and ultrasound echo in pregnant women,and to follow early pregnancy outcomes.Comparative analysis of the results of ultrasonography in abortion women,women with threatened abortion,and women in normal pregnancy.Results:Among 300 pregnant women in early pregnancy,232(77.33%)were normal early pregnant women,and 68(22.67%)had threatened abortion.Among them,25(36.76%)had abortion and 43(63.24%)continued to have pregnancy.There were significant differences in PI and RI values between the three groups of uterine spiral arteries and corpus luteum blood flow(P<0.05),and the abortion group was higher than the threatened abortion continued pregnancy group and the normal early pregnancy group.The proportions of the three groups of different shapes of corpus luteum were statistically significant(P<0.05).Among them,the proportion of point shape and rod-shaped corpus luteum was the highest in the abortion group.The abnormal rate of corpus luteum in the abortion group was higher than that in the threatened abortion continued pregnancy group,and the difference was statistically significant(P<0.05).There were significant differences in the ultrasound echoes between the three groups(P<0.05).Among them,the abortion group had the highest proportion of corpus luteum hypoechoic.Conclusions:Transvaginal ultrasound monitoring of uterine spiral arteries,corpus luteum blood flow and corpus luteum shape,size,and ultrasound echo in early pregnancy has certain diagnostic value for early pregnancy abortion.
