摘要
目的:分析稽留流产超声子宫动脉血流动力学特征及其预测。方法:选取2019年3月~2022年6月在本院行超声检查的早期妊娠孕妇,共88例。根据超声结果分为稽留流产组(26例)、稽留流产阶段组(22例)、对照组(40例)。将所有患者行阴道彩色多普勒检查,比较3组子宫动脉血流收缩期最大峰值流速与舒张末期流速比值(S/D)、阻力指数(RI)、搏动指数(PI)并分析对稽留流产的预测价值。结果:初步诊断、妊娠<10周及妊娠10~12周时,稽留流产阶段组的子宫动脉血流S/D、RI及PI值高于对照组(P<0.05),稽留流产组的子宫动脉血流S/D、RI及PI值低于对照组(P<0.05)。以子宫动脉血流S/D、RI及PI值当做自变量,经Logistic回归分析,S/D、RI是引发稽留流产的危险因素(P<0.05),PI值对稽留流产无预测效能。结论:对早期妊娠孕妇测定子宫动脉血流S/D、RI及PI值可对稽留流产进行诊断,并且S/D、RI值对稽留流产有一定预测价值,可作为参考依据。
Objective:To analyze the characteristics and prediction of ultrasonic uterine artery hemodynamics in missed abortion.Methods:88 early pregnant women who were examined by ultrasound in our hospital from March 2019 to June 2022 were selected.According to the ultrasonic results,they were divided into missed abortion group(26 cases),missed abortion transition group(22 cases)and control group(40 cases).All patients were examined by vaginal color Doppler flow imaging.The peak systolic/end diastolic velocity(S/D),resistance index(RI)and pulsatility index(PI)of uterine artery blood flow in the three groups were compared,and the predictive value of missed abortion was analyzed.Results:The values of S/D,RI and PI of uterine artery blood flow in the missed abortion group were higher than those in the control group(P<0.05),but the values of S/D,RI and PI of uterine artery blood flow in the missed abortion group were lower than those in the control group(P<0.05).With uterine artery blood flow S/D,RI and PI values as independent variables,Logistic regression analysis showed that S/D,RI were risk factors for missed abortion(P<0.05),and PI values had no predictive effect on missed abortion.Conclusion:The measurement of S/D,RI and PI values of uterine artery blood flow in early pregnant women can diagnose missed abortion,and S/D,RI values have certain predictive value for missed abortion,which can be used as a reference.
