摘要
目的探讨主动脉峡部(AoI)搏动指数(PI)对评价子痫前期胎儿血流动力学改变的临床价值。方法 261名单胎孕妇接受产前超声检查,以其中47例子痫前期患者作为病例组,另自214名正常孕妇中选取47名作为对照组。观察214名正常孕妇AoI-PI随孕周的变化,以及病例组胎儿出生前AoI-PI、CPR变化。结果正常胎儿AoI-PI随孕周增加略有增加。病例组胎儿AoI-PI较对照组增加(P<0.001),CPR较对照组降低(P<0.001),且病例组AoI-PI异常改变早于CPR。结论 AoI-PI变化可以提示子痫前期患者胎儿血流动力学改变。
Objective To evaluate the clinical value of aortic isthmus pulsatility index(AoI-PI) on intrauterine hemodynamic changes in fetus of preeclampsia patients. Methods Totally 261 pregnant women who underwent prenatal ultrasound were selected, including 214 normal pregnant women(47 selected as control group) and 47 preeclampsia patients(case group). The changes of fetal AoI-PI with gestational age were observed in 214 normal pregnant women. Fetal AoI-PI and cerebroplacental ratio(CPR) were compared between 2 groups. Results Fetal AoI-PI in normal pregnant women slightly increased with gestational age. Fetal AoI-PI in case group was higher than in control group(P<0.001), while CPR was lower than that in control group(P<0.001). The abnormal changes of AoI-PI were earlier than those of CPR in case group. Conclusion Fetal AoI-PI can indicate hemodynamic changes in fetus of preeclampsia patients.
