To study the role of spiral, uterine artery doppler in early second trimester to predict hypertensive disorders of pregnancy

Aims and Objectives: To study the usefulness of uterine artery diastolic notch in second trimester for early prediction of Hypertensive disorders of pregnancy and it’s associations with gestational age of onset of hypertension, delivery and Low birth weight. Methodology: This was an Observational prospective case control study performed on 184 antenatal women. The presence of a uterine artery doppler diastolic notch of >50% was assessed at 13-16th week of gestation. Spiral artery doppler was also assessed. Blood pressure at each antenatal visit was recorded and gestational age of development of hypertension and delivery was noted. Results were calculated using Statistical Program for Social Science (SPSS) version 20.0. Results and Conclusion: Out of 39 women with notch (+), hypertension developed in 24 women (61%) thus proving that presence of a uterine artery diastolic notch is an indicator for subsequent development of hypertension (p-value < 0.0001, statistically significant). The overall sensitivity, specificity, positive and negative predictive value and accuracy of the test was 61.5%, 91.7%, 66.7% and 89.9%, 85.3%.
