Preeclampsia is a disease with worldwide significance to mothers andinfants. Its greatest impact is in developing countries, where it accounts for 20–80% of the maternal mortality. Surveillance by Doppler velocimetry of theumbilical, middle cerebral arteries and ductus venosus is a non-invasive clinicalapproach for the evaluation of pre-eclampsia. Material and Methods: Dopplerof umbilical, middle cerebral arteries and ductus venosus were measured in 30pregnant patients with preeclampsia 20-35 years old, singleton pregnancy at 28-40 weeks gestation, not obese not chronically hypertensive, not having chronicrenal or liver disease nor diabetic and 30 controls matched to case in age ,gestational age. Results: middle cerebral artery/ umbilical artery RI ratio issignificantly lower in preeclamptic patients versus normal pregnant, there wasno increase in ductal flow except in 4 cases first seen with severe preeclampsiawhich was terminated & the newborn was transferred to neonatal ICUconclusion: middle cerebral artery/ umbilical artery RI ratio is significantlylower in preeclamptic patients versus normal pregnants with significantcorrelation to neonatal outcome. Ductal venosus Doppler studies may have arole in severe preterm preeclampsia.
