BACKGROUND: Doppler velocimetry studies of umbilical artery (UA) and middle cerebral artery (MCA) flow help to determine the presence and severity of fetal growth restriction. Increased UA resistance and reduced MCA pulsatility may indicate increased placental resistance and intrafetal blood flow redistribution. Malaria causes low birth weight and fetal growth restriction, but few studies have assessed its effects on uteroplacental and fetoplacental blood flow. METHODS: Colour-pulsed Doppler ultrasound was used to assess UA and MCA flow in 396 Papua New Guinean singleton fetuses...

OBJECTIVE: Low cerebroplacental ratio (CPR) near term has emerged as a marker of fetal adverse outcome. The aim of this study was to evaluate the predictive accuracy of an alternative ratio using the vertebral artery (VA) (vertebroplacental ratio or VPR) for acid-base status at birth. METHODS: This was a prospective cohort study of 1470 pregnancies undergoing an ultrasound assessment of the umbilical artery, middle cerebral artery and VA Doppler beyond 34 weeks' gestation within 14 days of delivery...

OBJECTIVE: The primary aim of this study was to evaluate if the magnitude of change in the cerebro-placental ratio (CPR) after 30 weeks gestation was better predictive of adverse pregnancy outcome compared to a single measurement at 35-37 weeks. A secondary aim was to evaluate whether the utility of CPR measured at 35-37 weeks was enhanced after adjusting for the gestational change. METHODS: This was a retrospective cohort study of women who had had at least two ultrasound scans between 30-37 weeks gestation with the final scan taking place at 35-37 weeks...

AIM: The study aimed to investigate the use of fetal cerebroplacental ratio (CPR) to identify fetuses at high risk before labor due to the brain sparing phenomenon. MATERIALS AND METHODS: Four hundred and seventy-six singleton pregnancies were enrolled in this study. The CPR was recorded within 1 week of delivery and labor was managed according to local protocols and guidelines. Intrapartum and neonatal outcome details were recorded. RESULTS: The CPR values of fetuses subsequently presenting category III intrapartum electronic fetal monitoring (EFM) or category II EFM without improvement (category IIB EFM) or with progression to category III (category IIC EFM) were significantly lower...

Identification of the fetus at risk of adverse outcome at term is a challenge to both clinicians and researchers alike. Despite the fact that fetal growth restriction (FGR) is a known risk factor for stillbirth, at least two thirds of the stillbirth cases at term are not small for gestational age (SGA) - a commonly used proxy for FGR. However, the majority of SGA fetuses are constitutionally small babies and do not suffer from adverse perinatal outcome. The cerebroplacental ratio (CPR) is emerging as a marker of failure to reach growth potential at term...
