高危妊娠子宫动脉血流动力学变化及对妊娠结局的影响

目的 探讨高危妊娠子宫动脉的血流动力学及与妊娠结局的关系。方法 高危妊娠组62例，正常妊娠组32例。经彩色多普勒检测两组双例子宫动脉的阻力并与妊娠结局相比较。结果 高危妊娠组子宫动脉的收缩期峰值速度／舒张期血流速度值显著高于正常妊娠组；高危妊娠组子宫动脉舒张早期切迹的出现率显著高于正常妊娠组；高危妊娠组的妊娠结局较差。结论 子宫动脉的彩色多普勒血流动力学检测对研究妊娠病理生理及对高危妊娠围产儿结局的监测具有很大的实用价值。

Changes of the uterine artery hemodynamics in high-risk pregnancy and pregnant outcome

Objective To study the uterine artery hemodynamics of the high risk pregnancy and its relation with the pregnant outcome.Methods The resistance of bilateral uterine artery was measured by color Doppler and was compared with outcome in 62 high risk pregnant cases and 32 normal pregnant cases.Results The systolic/diastolic ratio of uterine artery in the high risk pregnant group was significantly higher than that in normal pregnant group.The incidence of uterine artery notch was obviously higher in high risk pregnant group than that in normal pregnant group.The high risk pregnant group had the worse outcome.Conclusion The uterine artery hemodynamics monitored by color Doppler is useful in surveillance of pathophysiology of high risk pregnancy and the outcome.
