title: [Value of quantitative measurement of placenta with three-dimensional power Doppler ultrasonography in pregnant women with pregnancy-induced hypertension].
abstract: OBJECTIVE
  To evaluate the intrauterine state of fetuses with pregnancy-induced hypertension (PIH) through quantitative measurement of placenta by three-dimensional power Doppler ultrasonography, and to judge the value of three-dimensional power Doppler in PIH fetuses.
  
  
  METHODS
  A total of 50 pregnant women with PIH in our hospital from November 2012 to August 2014 were enrolled into the observation group, while 50 cases were randomly selected into the control group to match the former group's gestational week (GA). The placental vascularization index (VI), flow index (FI) and vascularization flow index (VFI) were quantitatively measured by three-dimensional power Doppler ultrasonography in the two groups. SPSS 19 statistics software was used to do the linear regression for the above parameters.And those parameters of the two groups were compared by t test. P<0.05 was deemed significant.
  
  
  RESULTS
  The detection ratio of fetal placental VI, FI and VFI of the whole 100 cases was 100%. The regression equation of VI and GA was: Y=0.394X-5.358, R² = 0.694, P<0.05; the regression equation of FI and GA was: Y=0.801X+5.61, R² = 0.807, P<0.05; the regression equation of VFI and GA was: Y=0.225X-4.148, R² = 0.691, P<0.05. t tests showed the differences of the means of placental VI, FI and VFI between the observation group and the control group were statistically significant (all P<0.05).
  
  
  CONCLUSIONS
  VI, FI and VFI of placenta measured by three-dimensional power Doppler examination increase with the increase of GA, and the means of placental VI, FI and VFI in PIH patients are less than those in normal cases. Quantitative measurement of placenta with three-dimensional power Doppler ultrasound has its own advantages, and can evaluate the status of placenta of PIH fetus accurately.
