Cerebroplacental ratio assessment for the prediction of adverse perinatal outcomes in gestational hypertensive term pregnancy

Abstract

Background Cerebroplacental ratio (CPR) assessment in late third trimester in gestational hypertension (HTN) can be used to predict adverse perinatal outcome. Aim To evaluate whether CPR assessment in late pregnancy can predict suspected fetal compromise or occurrence of adverse perinatal outcomes in singleton term pregnancy with controlled gestational HTN. Patient and methods This prospective study was conducted in El Zahraa University Hospital on 100 pregnant women who were divided equally into control group and gestational HTN group. LOGIC V5 ultrasound equipment was used to measure umbilical artery pulsatility index and middle cerebral artery pulsatility index and CPR. Results There was a statistically significant decrease of the mean CPR in gestational hypertensive group when compared with the control group (P<0.001) and a highly statistically significant decrease in the mean estimated fetal weight (P<0.001) and Apgar score (P=0.012) in gestational hypertensive group when compared with the control group. Conclusion Study of the pulsatility indices of placental and fetal circulation in women with singleton term pregnancy who developed gestational HTN can provide important information about fetal well-being to be an opportunity to improve fetal outcome.
