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侧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。
Objective To investigate the relationship between the hemodynamics of uterine artery and pregnancy outcome in high-risk pregnancy. Methods 62 cases of high risk pregnancy group, 32 cases of normal pregnancy group. Color Doppler detection of bilateral two groups of uterine artery resistance and pregnancy compared with the outcome. Results The peak systolic velocity / diastolic velocity of uterine artery in high risk pregnancy group were significantly higher than those in normal pregnancy group. The incidence of early diastolic uterine notch in high risk pregnancy group was significantly higher than that in normal pregnancy group. Pregnancy outcome in high risk pregnancy group Poor. Conclusion The color Doppler hemodynamics test of uterine artery has great practical value for studying the pathophysiology of pregnancy and monitoring the perinatal outcome of high-risk pregnancy.
