Background: Doppler velocimetry was used to investigate the typical physiological vascular changes that take place within the placenta and the fetus and application of these changes to predict high risk pregnancy and perinatal outcome.
Aim and objectives: to evaluate neonatal outcome among high risk pregnant women depending on fetal cerebroplacental ratio (CPR) versus uterine artery (UtA) Doppler.
Subjects and methods: This current study was a prospective randomized control trial which was conducted at ElShatby Maternity University Hospital from January 2021 to December 2022 after being approved by the Faculty of Medicine- Port-said University ethical committee on 119 singleton high risk pregnancies which were distributed at random into group A who were evaluated by CPR and group B who were evaluated by UtA.
Results: In current study there was a statistically significant difference between the studied groups regarding fetal CPR Doppler ultrasonography, comparison of neonatal characteristics except in infant sex and neonatal outcome. APGAR score at 5th min, CPR ,middle cerebral artery (MCA) PI(pulsatility index), MCA peak systolic velocity(PSV) have statistically significant positive correlation with birth weight while umbilical artery (UA) PI, umbilical cerebral ratio (UCR), UtA PI and UtA resistance index (RI) have statistically significant negative correlation with birth weight.
Conclusion: In high risk pregnancies, the CPR and UtA Doppler have a significant impact on the ability to predict the fate of the perinatal period.
