Abstract
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.
