Analysis on the Detection of PTA Blood Current of the PIH Pregnant Women by Means of the Ultrasonic Wave / 中国医学影像技术

ABSTRACT

ObjectiveTo provide a new method for the predictive diagnosis of PIH through the detection of the PTA blood flowing indexes of the pregnant women. MethodTo adopt the color Doppler ultrasonic wave the conduct the contrast normal pregnant women and PIH women of post-pregnancy 30 cases respectively. Results①The peak value flow rate of blood at diastolic period (short for D), the average blood flow rate (short for MN), the ratio of the peak value blood flow rate (S/D) for PIH group are higher than those for the other two groups respectively (P<0.01); ②There is no statistic difference in the changes of the PTA artery internal diameter between the three groups. ConclusionThe changes in the PTA blood flow indexes of the PIH patients provides a new method for the diagnosis of this disease, which is of some reference value. Such indexes as S, MN and S/D of the PTA are better targets for observation.
