Objective: To study the relationship between placental microcirculation function and umbilical blood flow in pregnancy induced hypertension(PIH) women. Methods: Blood flow velocity S/D and volumetric flow of umbilical artery were detected by Doppler ultrasound in 67 PIH women. Sametimes, their urinary E/C was detected. Results: Placental microcirculation function, whose umbilical artery S/D≥3 gradually reduced for their urinary E/C<15 and their low volumetric flow of umbilical artery. The prevalences of IUGR and 1 min Apgar score were significantly higher in women with S/D≥3 as compared normal umbilical artery blood flow velocity women(S/D<3). Conclusion: The changes of placental microcirculation was related to umbilical artery S/D and volumetric flow. S/D of umbilical artery is a sensitive monitoring index on reaction placental microcirculation function. It can be used to judge pregnancy outcome of PIH women.
