【摘要】 目的：探討经阴道彩色多普勒超声在早期妊娠孕妇子宫动脉血流与先兆流产结局中的应用价值。方法：选取2020年5-12月因疑似先兆流产来本院接受检查及治疗的60例早期妊娠孕妇为研究组，并根据随访结果分为持续妊娠组（妊娠在16周以上，33例）与难免流产组（由先兆流产发展至难免流产，妊娠时间在16周以内，27例）。并选取同时期来本院产检的60例早期妊娠孕妇为对照组。三组均接受经阴道彩色多普勒超声检查，比较其子宫动脉血流参数。结果：三组入院时S/D、RI比较，差异均有统计学意义（P<0.05）。难免流产组、持续妊娠组入院时S/D与RI值均高于对照组，且难免流产组均高于持续妊娠组（P<0.05）。三组妊娠8周S/D、RI及妊娠10～12周RI比较，差异均有统计学意义（P<0.05）;难免流产组与持续妊娠组妊娠8周S/D、RI及PI均高于对照组，且难免流产组均高于持续妊娠组（P<0.05）。难免流产组妊娠10～12周RI均高于持续妊娠组及对照组（P<0.05）。结论：早期妊娠孕妇经阴道彩色多普勒进行子宫动脉血流参数检测，可将其检测数据作为对早期先兆流产的有效参考，有助于对孕妇预后状况的评估，利于推广应用。

Application Value of Transvaginal Color Doppler Ultrasound in Uterine Artery Blood Flow and Threatened Abortion Outcome in Early Pregnancy Women/LYU Kui， LI Zhenxing， LIANG Lijuan， GUAN Qiuxian， DAI Liwen. //Medical Innovation of China， 2021， 18（34）： -149

[Abstract] Objective： To explore the application value of transvaginal color Doppler ultrasound in uterine artery blood flow and threatened abortion outcome in early pregnancy women. Method： From May to December 2020， 60 pregnant women with suspected threatened abortion who came to our hospital for examination and treatment were selected as the study group. According to the follow-up results， they were divided into continuous pregnancy group （33 cases with gestation over 16 weeks） and unavoidable abortion group （27 cases with gestation less than 16 weeks）. At the same time， 60 early pregnant women in our hospital were selected as the control group. The three groups were examined by transvaginal color Doppler ultrasound， and the uterine artery blood flow parameters were compared. Result： The differences in S/D and RI of three groups at admission were statistically significant （P<0.05）. The S/D and RI values of the unavoidable abortion group and the continuous pregnancy group were higher than those of the control group， and the unavoidable abortion group were higher than those of the continuous pregnancy group （P<0.05）. The S/D and RI at 8 weeks of gestation and RI at 10-12 weeks of gestation among three groups compared， there were statistically significant （P<0.05）; the S/D， RI and PI in the unavoidable abortion group and the continuous pregnancy group at 8 weeks of gestation were higher than those of the control group， the unavoidable abortion group were higher than those of the continuous pregnancy group （P<0.05）. The RI in the unavoidable abortion group at 10-12 weeks of gestation was higher than those in the continuous pregnancy group and the control group （P<0.05）. Conclusion： The detection of uterine artery blood flow parameters of early pregnant women by transvaginal color Doppler can be used as an effective reference for early threatened abortion， which is helpful to evaluate the prognosis of pregnant women and promote the application.

在女性妊娠期间，先兆流产是其自然流产临床病程发展的初级阶段，其中在早孕时期较为常见，并具有较高的发生率，其中部分患者可能发展为难免流产，对孕妇身体健康产生不利影响[1]。先兆流产的发病原因相对复杂，且……
