Aim and Objectives: The purpose of this study was to evaluate the role of umbilical artery doppler among pregnant women with Pregnancy Induced Hypertension (PIH) with clinical suspicion of IUGR and to predict the foetal outcome.

Materials and Method: A total of 72 women with high-risk pregnancy were subjected to uterine and umbilical artery Doppler study. In this prospective study, women having high-risk pregnancies between 26 and 30 weeks of gestation were observed for one years. We investigated at the flow velocity forms in the uterine and umbilical arteries. S/D ratio and RI (resistance index) in the uterine and umbilical arteries were investigated. S/D ratio and a RI that deviates from the mean by more than 95% were categorised as abnormal.

Results: S/D ratio and notch on uterine artery Doppler imaging independently demonstrated 60% sensitivity and 33.3% and 37.5% positive predictive values, respectively, for pre eclampsia. Notch on uterine artery Doppler imaging was the best indicator with the highest sensitivity (25%) and positive predictive value (25%) for PIH as compared to other indices. Doppler S/D ratio had the best positive predictive value (40%) and RI had the best sensitivity (42.86%) for predicting IUGR.

Conclusion: Uterine and umbilical arteries combined the greatest indication for predicting preeclampsia and IUGR is the doppler. Better than the individual Doppler indices in the uterine artery is the diastolic notch as a single measure. The strongest indicator of preeclampsia and a poor foetal outcome is absent end diastolic flow.
