子宫动脉血流动力学参数的变化与稽留流产的关系

The Relationship Between the Change of Hemodynamic Parameters of Uterine Artery and Missed Abortion

目的探究子宫动脉血流动力学参数变化对稽留流产的影响。方法选取2019年5月-2020年5月我院收治的稽留流产患者100例设置为试验组,另选取同期正常早孕者100例,设置为参照组。所有患者采取阴道彩色多普勒检查,对比分析两组患者子宫动脉血流动力学参数,包括收缩/舒张末流速比(S/D)、阻力指数(RI)、搏动指数(PI)。结果与参照组相比,试验组子宫动脉阻力指数与搏动指数较高,差异具有统计学意义,P<0.05;与参照组相比,试验组子宫动脉收缩/舒张末流速比较高,差异无统计学意义,P>0.05。结论子宫动脉血流动力学参数越高提示稽留流产发生率越高,对子宫动脉血流动力学参数变化进行密切监测有利于稽留流产的诊断与预防。

Objective To explore the influence of changes of uterine arterial blood flow mechanical parameters on missed abortion.Methods 100 cases of missed abortion admitted to our hospital from May 2019 to May 2020 were selected as the experimental group,and 100 cases of normal early pregnancy during the same period were selected as the reference group.Vaginal color Doppler ultrasonography was performed in all patients to compare and analyze the uterine arterial hemodynamic parameters,including systolic/diastolic velocity ratio(S/D),resistance index(RI),and pulsation index(PI).Results Compared with the control group,the uterine artery resistance index and pulse index in the experimental group were significantly higher,with statistical difference(P<0.05).Compared with the control group,the rate of uterine artery contraction/diastolic end flow was higher in the experimental group,but there was no statistical difference(P>0.05).Conclusion The higher the uterine artery hemodynamic parameters were,the higher the incidence of missed abortion.
