Role of Uterine Artery Doppler In Predicting Preeclampsia.

Abstract

AIMS AND OBJECTIVES 1. To evaluate whether abnormal uterine artery Doppler study can be used as an effective screening test to predict the development of pre-eclampsia at 14-20 weeks of gestation. 2. To study the flow velocity waveforms in the uterine arteries in mid-trimester. METHODS This study is a prospective study including105 woman with singleton pregnancy between 14 to 20 weeks of gestation over the period of 2 years. Bilateral uterine artery Doppler flow velocity was studied. In both uterine arteries, RI, PI and S/D ratio were studied. The presence of early diastolic notch is noted in both the uterine arteries. RESULTS 100 patients were taken for analysis as five patients were excluded from the study. Out of 100 patients, 7 patients developed preeclampsia. Uterine artery Doppler was abnormal in 9 patients with sensitivity of 87% and specificity of 97% for pre eclampsia. INTERPRETATION AND CONCLUSION Uterine artery Doppler in 2nd trimester (14-20 wks) can be used as a good screening test for prediction of preeclampsia. Therefore, it helps in early detection of at risk women and early treatment and favorable outcome.
