The aim is to assess the role of uterine artery Doppler indices (PI, RI) in predicting pregnancy hypertensive disorders.Methods : 30 pregnant females were included; they were subjected to uterine artery Doppler in the first trimester at 11-14 weeks gestation. All pregnancies were followed until 40 weeks for development of preeclampsia.Results: Cases that develop preeclampisia compared to those who did not develop preeclampisia already have increased prevalence of unilateral /Bilateral diastolic notching and higher PI and RI. All these were of statistically significant difference.Conclusion : Use of uterine artery Doppler indices in first trimester of pregnancy is valuable in predicting development of preeclampisia.
