【摘要】 目的 探讨高危妊娠孕妇胎盘床螺旋动脉与子宫动脉的血流动力学的变化。方法 高危妊娠组85例，正常妊娠组107例。经彩色多普勒超声检测孕妇胎盘床螺旋动脉及子宫动脉血流动力学，并比较高危妊娠组和正常妊娠组孕妇血管阻力参数。结果 正常妊娠组孕妇子宫动脉25周后血管阻力明显下降，至33周后血管阻力参数保持稳定到分娩；高危妊娠组孕妇子宫动脉血管阻力持续无明显改变；至33周后高危妊娠组孕妇子宫动脉阻力系数明显高于正常妊娠组(P<0.05)。高危妊娠组孕妇20周后胎盘床螺旋动脉阻力明显高于同期正常妊娠组(P<0.05)，两组孕妇胎盘床螺旋动脉20周后血管阻力参数保持稳定到分娩。结论 应用彩色多普勒超声可显示胎盘床螺旋动脉血流动力学的变化，为早期预测高危妊娠的并发症提供依据。

【Abstract】 Objective To investigate the changes of arteria helieinae and arteria uterina blood flow in high risk pregnancy. Methods 85patients were high risk pregnancy and 107 cases were normal pregnancy. The arteria helieinae and arteria uterine of normal pregnancy and high risk pregnancy groups were compared by color doppler ultrasound. Results After 25 weeks, the vascular resistance of arteria uterina of the normal pregnancy group decreased obviously. From 33 weeks to accouchement, the vascular resistance parameter of arteria uterina of holded stabilize. The vascular resistance of arteria uterina of the high risk pregnancy group continued to no change obviously. After 33 weeks, the vascular resistance of arteria uterina of the high risk pregnancy group was higher than the normal pregnancy group(P<0.05). After 20 weeks, the vascular resistance of arteria helieinae of the high risk pregnancy group was higher than the normal pregnancy group(P<0.05). From 33 weeks to accouchement, the vascular resistance of arteria helieinae of the two groups maintained stable. Conclusion Color doppler ultrasound can show the changes of arteria helieinae which can provid evidence of early prediction high risk pregnancy complication.
