PURPOSE: This study aimed to determine whether the stiffness of the arterial walls of women with preeclampsia (PE) differs from that of healthy controls and to evaluate its association with fetal and uterine artery Doppler variables and perinatal outcomes in PE. METHODS: We enrolled 30 women with PE and 30 normotensive pregnant women. Carotid artery stiffness and Doppler variables of the uterine, umbilical, and fetal middle cerebral arteries and the ductus venosus were measured in both groups...

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...

OBJECTIVES: To assess studies reporting reference ranges for Doppler indices of umbilical artery (UA), middle cerebral artery (MCA) and cerebroplacental ratio (CPR), using a set of predefined methodological quality criteria for study design, statistical analysis and reporting methods. METHODS: A systematic review of observational studies whose primary aim was to create reference ranges for Doppler indices of UA, MCA, and CPR in fetuses from singleton gestations was performed in MEDLINE, EMBASE, CINAHL, and Web of Science (all from inception to December 31, 2016), and references of retrieved articles...

OBJECTIVE: The aim of this study was to perform a comprehensive assessment of the placental aging process through senescence and apoptotic markers in late-onset small fetuses classified as SGA or FGR. STUDY DESIGN: A prospective nested case-control study in singleton pregnancies delivering at term including 21 normally grown fetuses and 36 small fetuses classified into SGA (if birthweight was between the 3rd and 9th centile and normal fetoplacental Doppler; n=18) and FGR (if birthweight <3rd centile and/or abnormal cerebroplacental ratio or uterine artery Doppler; n=18)...

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...

OBJECTIVE: We aimed to review a single-center experience in follow-up and management of fetuses with umbilical vein varix (UVV) and to assess the effect of UVV on fetal Doppler parameters. METHODS: We reviewed retrospectively maternal antenatal records, delivery records, and newborn records to identify cases of UVV. Further, we retrospectively compared 25 fetuses with isolated UVV and available cerebroplacental ratio (CPR) analysis with 75 matched controls. RESULTS: We identified 67 cases of UVV...

Aim: To investigate the potential value of Doppler ultrasound and to assess cerebroplacental ratio (CPR) in the prediction of adverse perinatal outcome defined as Apgar score < 7 at 1 minute. Material and methods: This was a retrospective cross-sectional study in selected pregnant women undergoing an ultrasound examination between 36 and 42 weeks of gestation. We measured estimated fetal weight (EFW), mean umbilical artery pulsatility index (UA PI), mean middle cerebral artery pulsatility index (MCA PI), CPR, and Apgar score in 1 minute...

OBJECTIVES: Endocan plays a role in the development of vascular tissue in health and disease and is an indicator of endothelial cells activation and angiogenesis. Therefore, this study aimed to investigate the relationship between maternal endocan serum level and intrauterine growth restriction (IUGR) as well as ultrasound Doppler flow measurements indicating placental insufficiency. METHODS: This study included a group of women with IUGR (n = 37) and a group of healthy pregnant women (controls, n = 37)...
