| 摘 要： | 目的 探讨妊高征患者的眼动脉 (OA)多普勒超声特点及其与总外周血管阻力的关系。方法 妊高征(PIH)患者 35例 ,正常妊娠 (NP) 2 6例 ,在彩色多普勒超声引导下 ,利用脉冲多普勒测量OA的血流参数 ,测量主动脉瓣环处内径并记录该处血流频谱 ,计算总外周血管阻力指数 (TPVRI)。结果 与NP组比较PIH组OA的RI及PI明显减低 (P <0 0 5 ) ;B峰显著增高 (P <0 0 1) ;B/A显著增大 (0 74± 0 13vs 0 47± 0 15P <0 0 1) ,与TPVRI及平均动脉压 (MAP)明显相关 ,r分别为 0 6 6和 0 6 3(P均 <0 0 0 1)。结论 妊高征患者OA血流动力学变化以阻力减低、B峰值流速增快及B/A值增高为主 ,且与TPVRI增高相一致。B/A在一定程度上可反映TPVRI的大小
