Objectives: Till date, there is no concrete consensus on using uterine Doppler measurements for predicting adverse outcomes in early stages of pregnancy between 6-14 weeks. Hence, we planned this current study to find out the role of uterine artery Doppler in predicting miscarriage in early pregnancy and to find out the abnormality of which uterine artery Doppler indices is associated with complicated pregnancy and with the adverse outcome.
Materials and Methods: A cross sectional prospective study in which uterine artery Doppler of both right. & left uterine arteries were estimated & the mean was taken for the three indices (PI, RI & S/D ratio) for each patient. The gestational age at which the Doppler study was done was 6-14 weeks for all groups. The groups of normal and threatened miscarriage were followed up for outcome up to 20 weeks of gestation.
Results: There was significant difference in the means of PI, RI and SD ratio among three groups. It was found that only PI was found to be significantly associated with the outcome of pregnancy. The cut- off value for PI was found to be 2.64 at 91% sensitivity and 81% specificity for predicting miscarriage.
Conclusions: Uterine artery Doppler should be introduced as routine screening test to identify women who could have adverse pregnancy outcome for its effective management.
