摘要
[目的]探讨彩色多普勒超声检测孕妇子宫动脉的血流动力学变化对子痫前期的预测价值。[方法]选择在本院建卡产检并分娩的孕妇共90例，根据妊娠经过及妊娠结局分为妊娠高血压组、子痫前期组及对照组，所有孕妇均在孕22-24周接受彩色多普勒超声检查，比较三组孕妇子宫动脉收缩期峰值流速与舒张末期血流速度的比值（S／D）、平均搏动指数（PI）及阻力指数（RI）及有无舒张早期“V”行切迹波出现。[结果]妊娠高血压组、子痫前期组孕妇双侧子宫动脉的S／D、PI、RI值均较对照组高（P〈0．05）；且子宫动脉S／D、PI、RI值显著高于妊娠高血压组（P〈0．05）。对照组孕妇两侧子宫动脉血流频谱显示无一例出现舒张压早期“V”形切迹；妊娠高血压组两侧子宫动脉同时出现舒张期“V”形切迹18例，单独左侧出现10例，单独右侧出现2例；子痫前期组两侧子宫动脉同时出现舒张期“V”形切迹21例，单独左侧出现7例，单独右侧出现2例。[结论]彩色多普勒超声检测孕妇子宫动脉血流动力学变化对子痫前期可早期预测，为临床子痫前期的早期诊断及治疗提供有价值的依据。
[Objective]To explore the predictive value of Color Doppler Ultrasound （CDU） detection of pregnant Uterine and arterial hemodynamic changes in pregnant women with preeclampsia.[Methods]A total of 90 cases of women were selected for this study. All of these women had their regular prenatal exams and delivery in our hospital. The patients were divided into three groups based on their pre-delivery characteristics： the hypertension group, preeclampsia group, and control group. All pregnant women were given the color Doppler ultrasonography during 22 - 24 weeks of gestation. The S/D（systolic/diastolic）, PI（pulse index）, RI（resistance index）, and V-wave of the early diastole of the uterine arteries were compared between the three groups.[Results]The S/D, PI, and RI of patients in the hypertension and preeclampsia groups were much higher than in patients of the control group （ P 〈0.05 ）. No subjects in the control group, With the normal pregnant women, was found to have the V-wave form in either side of the uterine artery. There were 18 subjects in the hypertension group who were found to have the V-wave characteristics in both sides of the uterine artery, 12 were found with the V-wave on only the left side, and 2 were found to have.the V-wave only on the right side. In the preeclampsia group, 21 women had the V-wave notch in both sides, 7 only on the left, and 2 only on the right.[Conclusion]The use of color Doppler ultrasound in testing uterine artery hemodynamics of pregnant women can lead to an early prediction of preeclampsia and provide valuable evidence for its early diagnosis and treatment.
