Objectives: Cerebroplacental ratio (CPR) is a useful tool in differentiating at-risk non-SGA fetuses. The first CPR reported by Arbeille et al quantifies the redistribution of the cardiac output. In this study, we investigate CPR in non-SGA fetuses.
Materials and Methods: This descriptive-analytic study was carried out in Ahvaz from January 1, 2016 to January 1, 2017. In this study, CPR was evaluated in 230 pregnant women at 28 to 38 weeks of gestation, with the exception of pregnant women with SGA and multiple pregnancies. In this study, factors such as maternal age, parity (nullipara and multipara), history of abortion, cesarean delivery or vaginal delivery, an estimate of fetal weight (EFW), history of stillbirth, pregnancy conceived through assisted reproductive technology, and NT values were investigated.
Results: In this study, of 230 pregnant women with an EFW more than the 3rd percentile and singleton pregnancy, there were 22 women with a CPR below the 5th centile. There was no relationship between the fetal CPR and the maternal age, the number of maternal cesarean section, the number of mother’s vaginal deliveries and the parity, history of stillbirth, pregnancy conceived through assisted reproductive technology and NT values in the data analyzed.
Conclusions:In this study, 9.6% of the non-SGA fetuses had abnormal CPR (less than 5 percentile). There is no relationship between CPR and maternal age, parity (nullipara and multipara), history of abortion, cesarean section delivery or vaginal delivery, EFW, history of stillbirth, pregnancy conceived through assisted reproductive technology, and NT values.
