Abstract: Hypertensive disorders of pregnancy are a leading cause of maternal as well as peri-natal mortality and morbidity. Impaired utero-placental circulation leads to fetal hypoxia and hence, brain sparing. Aim of the study is to determine the predictive value of Cerebro-placental Ratio (Middle Cerebral Artery Pi/ Umbilical artery Pi) in assessing perinatal outcome among hypertensive disorders of pregnancy. A prospective observational study was done in a tertiary care hospital, from July 2018-june 2019. One hundred consecutive singleton pregnancies with hypertension peculiar to pregnancy were enrolled. On serial Doppler ultrasounds, CPR was estimated and pregnancy followed up. The last ultrasound parameters before delivery were considered. Perinatal outcomes were studied. The sensitivity, specificity, positive predictive value and negative predictive value were calculated. CPR has a sensitivity of 49% in predicting SGA neonate and a specificity of 82%. CPR is highly valuable in predicting low birth weight and NICU admissions in neonates.
