ABSTRACT Objective This study was done to assess the Doppler cerebroplacental ratio (CPR) in the prediction of adverse perinatal outcome especially in growth restricted pregnancies. Materials and methods In this study, 62 antenatal women were subjected to Doppler studies at 34 to 42 weeks of gestations. CPR was calculated and less than 1 was taken as predictor of adverse perinatal outcome. Adverse perinatal outcomes was evaluated by mode of delivery, meconium staining, 1 and 5-minute Apgar scores, birth weight, admission to NICU and other neonatal complications.

Intrauterine growth restriction (IUGR) complicates 7-15% of pregnancies and is associated with adverse perinatal outcomes. The primary goal of antenatal care is the early detection of such conditions. Doppler studies in fetus are used to predict the morbidity in IUGR. Studies show that cerebroplacental ratio is a better predictor of IUGR babies and adverse perinatal outcome. In this study we compare perinatal outcomes of IUGR babies with a normal CPR and an abnormal CPR.

Background: Fetal growth restriction (FGR) is one of the leading causes of intrauterine fetal demise, cerebral palsy and perinatal death. The main cause of FGR is placental insufficiency. Cerebroplacental ratio (CPR) is decreased with the progression of FGR. Fetal aortic isthmus (AoI) Doppler has been suggested as a useful prognostic marker in monitoring of FGR fetuses. Objective of the study is to evaluate the relation between the AoI Doppler and CPR on the perinatal outcome in cases with FGR. Methods: This is a prospective observational cohort study that entailed 100 cases from November 2022

<strong>Introduction:</strong> Antepartum fetal surveillance is of immense importance for detecting fetal compromise in utero in high-risk pregnancies. The non-stress test (NST), contraction stress test (CST), biophysical profile (BPP), modified BPP (MBPP), and Doppler velocimetry are among the various tests used to evaluate high-risk pregnancies. This study was conducted to compare the diagnostic efficacy of the cerebroplacental ratio (CPR) and the non-stress test (NST) in predicting fetal compromise in hypertensive disorder of pregnancy (HDP). <strong>Methods: </strong>This is

Abstract Introduction: In pregnancy-induced hypertension (PIH) there is a disorder in placental blood flow which causes intrauterine fetal hypoxia, and oxidative stress has a significant role in this condition. The aims of this research were to analyze the relation of thiobarbituric acid reactive substance (TBARS), as a marker of oxidative stress and absent end-diastolic flow (AEDF), as well as the relation of TBARS and cerebroplacental ratio (CPR). Methods: The research included 200 pregnant women in the gestation period from 28th to 40th, 100 were in a control group and 100 were with PIH. Th

Abstract Objective To assess the degree of correlation/agreement of maternal–fetal Doppler parameters between normal and growth-restricted fetuses (fetal growth restriction [FGR]). Methods The present observational and retrospective study included 274 singleton pregnancies. The following maternal–fetal Doppler parameters were assessed: uterine artery (UAt), umbilical artery (UA), middle cerebral artery (MCA), cerebroplacental ratio (CPR), and umbilical–cerebral ratio (U/C). The assessment of FGR was based on the Figueiras and Gratacós9 criteria. Spearman correlation coefficients were estimated

IntroductionIntrapartum complications are a major contributor to adverse perinatal outcomes, including stillbirth, hypoxic–ischaemic brain injury and subsequent longer term disability. In many cases, hypoxia develops as a gradual process due to the inability of the fetus to tolerate the stress of parturition suggesting reduced fetoplacental reserve before labour commences. The fetal cerebroplacental ratio (CPR) is an independent predictor of intrapartum fetal compromise, poor acid base status at birth and of neonatal unit admission at term. Similarly, circulating maternal levels of placental g

Background/Aim: Fetal growth restriction (FGR) causes a high risk of perinatal morbidity and mortality, and the timing of the correct delivery time decision remains controversial. Cerebroplacental ratio (CPR), umbilical artery, uterine artery (UA) and middle cerebral artery (MCA) Doppler studies are used to predict adverse perinatal outcomes in FGR. However, since there is insufficient reliability for each separately and together, the search for new methods continues.

The effect is most likely related to the vasodilatative influence of PETN. To assess its impact on utero-placental and fetal perfusion, we analyzed the Doppler parameters measured during the PETN pilot-trial.Methods:One hundred and eleven pregnancies presenting impaired utero-placental resistance at mid-gestation were included in the trial.
