HEMODYNAMIC DOPPLER PARAMETERS IN THE FETUS FETOPLACENTAL UNIT WITH INTRAUTERINE GROWTH RESTRICTIONWITHIN PREGNANCY INDUCED HYPERTENSION

    Based on the spectral analysis of Doppler velocity waveform in uteroplacental and fetoplacental circulation, a Doppler parameters diagnostic efficiency was examined in fetus prenatal detection with intrauterine growth restriction (IUGR) within Pregnancy Induced Hypertension (PIH) and their respiratory menace.
    A prospective analysis was performed in 141 third-trimester pregnancies. The control group included 65 normal pregnancies and the expeimental group included 76 high-risk pregnancies, which was divided into three sub-groups, namely, 31 with IUGR within PIH, 24 with PIH only and 21 with IUGR only. The uterine artery was examined in uteroplacental circulation and umbilical artery was examined in fetoplacental circulation. Perinatal outcome and birth weight were recorded in each case.
    Uteroplacental circulation analysis showed statistically higer values of Pourcelot resistance index Ri in uterine artery in IUGR within PIH pregnancies. Statistically higher pulsatility index in umbilical artery was recorded in IUGR pregnancies compared to the control group and PIH subgroup. Higher values of pulsatility index were particulary noticed in IUGR within PIH subgroup. Doppler parameters in uteroplacental and fetoplacental circulation showed a significant negative correlation in relation to Apgar score of the newborn.
    In combination with biophysical profile and CTG, Doppler parameters diagnostic efficiency is increased on the evaluation of the fetus respiratory menace with IUGR and PIH. Acta Medica Medianae 2005;44(2): 37-45.
