PURPOSE OF REVIEW: Two-thirds of the pregnancies complicated by stillbirth demonstrate growth restriction. Identification of the foetus at risk of growth restriction is essential to reduce the risk of stillbirth. The aim of this review is to critically appraise the current evidence regarding clinical utility of cerebroplacental ratio (CPR) in antenatal surveillance. RECENT FINDINGS: The CPR has emerged as an assessment tool for foetuses at increased risk of growth disorders...

BACKGROUND: A low fetal cerebroplacental ratio (CPR) and nulliparity have independently been shown to be associated with adverse obstetric and perinatal outcomes. OBJECTIVES: To assess the effect of parity on the CPR and investigate the utility of a CPR threshold of <10th centile for predicting adverse outcomes. We hypothesised that nulliparous women would have a lower CPR than multiparous women, impacting the diagnostic performance of the <10th centile threshold...

INTRODUCTION: In intrauterine growth restriction (IUGR), increased uteroplacental vascular impedance contributes to preferential flow to left ventricle (LV), with consequent alteration of its compliance and increased left atrial (LA) pressure. Pulmonary vein pulsatility index (PVPI) reflects the increased impedance to LA filling and could be used as a cardiac monitoring parameter in IUGR. MATERIAL AND METHODS: A total of 27 IUGR fetuses (group 1), 28 fetuses with appropriate growth for gestational age from hypertensive mothers (group 2), and 28 controls (group 3) were studied...

INTRODUCTION: Intrapartum 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...

BACKGROUND: We previously reported that fetal plasma erythropoietin (EPO) concentrations are significantly increased in growth-restricted fetuses with abnormal umbilical artery (UA) Doppler. During hypoxia in an ovine model, the primary site of fetal EPO synthesis was switched from the kidneys to the placenta. Therefore, we designed this study to evaluate human placental EPO gene expression and the correlation to fetal serum EPO concentration in growth-restricted fetuses in a monochorionic (MC) twin model...

OBJECTIVE: To compare the fetal modified myocardial performance index (Mod-MPI) in appropriately grown, early (EO) and late onset (LO) fetal growth restricted (FGR) fetuses and to assess its prognostic significance for adverse perinatal outcome. STUDY DESIGN: In a prospective case-control study, Mod-MPI was performed in 22 and 51 fetuses with EO and LO-FGR fetuses, respectively. Mod-MPI values of FGR fetuses were compared against gestation-matched controls (34 for EO-, and 32 for LO-FGR, respectively)...

OBJECTIVE: The cerebroplacental ratio (CPR) has been proposed for the routine surveillance of pregnancies with suspected fetal growth restriction (FGR), but the predictive performance of this test is unclear. The aim of this study was to determine the accuracy of CPR for predicting adverse perinatal and neurodevelopmental outcomes in suspected FGR. METHODS: PubMed, EMBASE, CINAHL and Lilacs were searched from inception to 31 July 2017 for cohort or cross-sectional studies reporting on the accuracy of CPR for predicting adverse perinatal and/or neurodevelopmental outcomes in singleton pregnancies with FGR suspected antenatally based on sonographic parameters...

OBJECTIVES: The cerebroplacental ratio (CPR) Doppler has been proposed as an instrument for predicting adverse perinatal outcomes particularly during antepartum period. Abnormal CPR is associated with non-reassuring fetal status requiring operative delivery, low Apgar score and neonatal complications. The aim of this study was to assess the role of CPR Doppler in the labor triage suite, so as to identify fetuses at risk for non-reassuring status as well as other adverse perinatal outcomes...

INTRODUCTION: Doppler ultrasound has recently been suggested to identify subclinical placental functional impairment among normal sized term fetuses. The objective of this study was to evaluate the relationship between cerebroplacental ratio (CPR) measured in early labor and perinatal and delivery outcomes in a cohort of uncomplicated singleton term pregnancies. METHODS: This was a multicentre, prospective, observational study involving three Tertiary Centres. Low risk term pregnancies, as defined by the absence of any maternal morbidity and pregnancy complication and normal ultrasound and clinical screening of the fetal growth in the third trimester, with spontaneous onset of labor were included...
