Abstract: Obj ective To explore the value of renal artery (RA)hemodynamic changes in assessment of women with pregnancy-induced hypertension syndrome (PIH)and fetal growth re-striction (FGR).Methods 57 pregnant women with PIH and FGR and 57 normal pregnancy were examined by peak systolic flow velocity (Vmax),peak diastolic flow velocity (Vd),the average peak blood flow velocity cardiac cycle (Tamax),pulse rhythm(PI),resistance index(RI),the ratio (S/D)maximum blood flow speed during umbilical artery systole and diastole telophase.Results Vmax of fetal renal artery flow in the control group had a positive relationship with gestational age, and RI、PI、S/D showed a slow downward trend.Vmax and S/D of RA in pregnant women with PIH and FGR were significantly lower than those of the control group (P<0.001).Conclusion Normal fetal RA blood flow velocity is positively correlated with gestational age.The Vmax of RA<1 1 cm/s in pregnant women with PIH and FGR may predict a poor prognosis in fetal.
