Abstract
Background: Cerebroplacental ratio (CPR) is the ratio of middle cerebral artery pulsatility index to the umbilical artery pulsatility index. It compares the resistance to blood flow in the umbilical artery and middle cerebral artery and thus indicates the proportion of flow supplying the brain and placenta. The cerebroplacental ratio becomes less than one if any flow redistribution in favour of the brain occurs. The S/D of middle cerebral artery/ Umbilical artery <1 and pulsatility index of middle cerebral artery/ Umbilical artery (CPR) <1 are suggestive of brain sparing effect. This study examined the relationship between Doppler abnormalities with respect to cerebral and placental circulation in intrauterine growth retardation and abnormal pregnancy outcome in 100 patients
