Uterine Artery Notching on Color Doppler Ultrasound and Roll over Test in Prediction of Pregnancy Induced Hypertension.

OBJECTIVE To study the role of uterine artery notch on color Doppler ultrasound and roll over test in prediction of PIH. METHODS 100 women with high risk pregnancies were studied for presence or absence of uterine artery diastolic notch by Doppler ultrasound at 16-28 weeks. Same women were then subjected to roll over test at 28-32 weeks. RESULTS The primary outcome was that uterine diastolic notching alone and combined together with roll over test shows a high specificity (98.53%) for predicting PIH than roll over test (76.47%) alone. PPV of uterine artery diastolic notching (83.33%) was higher than roll over test alone (54.29%) and both tests combined together (80%). CONCLUSION After analyzing all the results, it has been concluded that uterine artery Doppler notching is better predictor for PIH than roll over test or even combined Doppler + Roll over test together.
