Background: Uterine artery Doppler ultrasonography may be performed via the transvaginal or transabdominal route in the first or second trimester. Uterine artery waveforms are reported to be readily obtainable in more than 95% of patients. Hence; the present study was conducted for assessing the role of Colour Doppler values as predictors of preeclampsia in 18-24 weeks of gestation. Materials & methods: A total of 25 patients with gestational age between 18 weeks to 24 weeks were enrolled in the present study. Complete demographic details of all the patients were obtained. Complete clinical examination of all the patients was carried out. Colour Doppler was carried out in all the patients. Patients were followed up to delivery and examination of the neonate was done. True incidence of pre-eclampsia was assessed and was compared with colour Doppler findings. Results: Pre-eclampsia was found to be present in 4 patients (16 percentages of patients). However; Doppler findings were found to be abnormal in 4 patients, while it was found to be abnormal in 21 patients. Out of 4 patients with abnormal Doppler findings, pre-eclampsia was found to be present in 2 patients, while it was found to be absent in 2 patients. Conclusion: By identification of the high risk patients & anticipating preeclampsia patients, close monitoring can be done to reduce the morbidity and improve the outcome of pregnancy.
