摘　　要：目的：为了解妊高征（ＰＩＨ）时，肾内小动脉（ＩＮＲＡ）和胎儿脐动脉（ＦＵＡ）多普勒血流频普变化。方法：用彩超分别检测６３例第三期妊娠和１２例非妊娠妇女上述血管Ｓ／Ｄ（收缩期血流速度峰值／舒张末期血流速度值）、ＲＩ（阻力指数）和ＰＩ（搏动指数），用ｔ检验统计。结果：在重度ＰＩＨ时，ＦＵＡ的Ｓ／Ｄ和ＰＩ较其它组高（Ｐ＜０．０５），ＲＩ＿（ｉｎｒａ）／ＲＩ＿（ｆｕａ）≤１；该值与ＰＩＨ血压呈负相关。在ＰＩＨ组，ＩＮＲＡ的Ｓ／Ｄ、ＲＩ和ＰＩ与对照组分别相比，有显著性差异。结论：在ＰＩＨ时，肾循环与胎儿胎盘循环在出血动力学方面有区别，为预测ＰＩＨ预后提供了新方法。Objective:To determine the changes of intrarenal smal artery(INRA)and fetal umbilical artery(FUA)Doppler velocity in pregnancy-induced-hypertension(PIH)women.Methods:The sys-tolic/diastolic ratio (S/D),resitstance index(RI)and pulsatility index (PI)of INRA and FUA were measured with color Doppler ultrasound in the third trimester of 63 pregnant and 12 nonpregnant wom-en respectively,T test was used for statistical analysis,Results:The mean values of S/D and PI in FUA were greater in the severe PIH group than in the other groups(P<0.05) and RI INRA/RIFUA was≤1 and it was negatively correlated with the blood pressure of PIH. The mean values of S/D and RI and PI in INRA in the PIH patients were different than those in the nonpregnant women(P<0.05).Conclusions:Renal and fetal-placental circulation were different in the blood hemodynamics.It may be valuable in anticipating the prognosis of women with PIH and this new method was recommended.
