The aim of the dissertation: to evaluate the prognostic value of fetal tibial artery blood flow Doppler parameters for perinatal outcomes in high-risk (hypertensive conditions, diabetes, intrahepatic cholestasis of pregnancy, COVID-19 infection) pregnancy with and without diagnosis of intrauterine growth restriction. During this research, the following indicators were measured and compared: Doppler pulsatility indices of fetal tibial artery, middle cerebral artery, umbilical artery and cerebroplacental ratio. The present study is the first to investigate and describe the characteristics and dynamics of Doppler pulsatility index of the peripheral tibial artery in low- and high-risk pregnant women from 33 to 40 weeks of gestation and compare the results with perinatal outcomes. The study showed no significant value in monitoring low-risk pregnancies. Significant changes were revealed by the results of measurements of parameters of the tibial artery in groups of high-risk pregnant women with diagnosed/undiagnosed fetal growth restriction. The results of this study showed that in the group of high-risk pregnant women with intrauterine growth restriction, the pulsatility indices of the lower tibial artery were the first to approach pathological values compared to the indices of other blood vessels. |
