Research on the second trimester's use of ultrasound to detect preeclampsia and growth restriction in the baby has been going on since at least the 1970s. Recently, there has been an increase in the usage of Doppler interrogation throughout the first trimester of pregnancy. The relationship between uterine artery Doppler velocimetry and adverse pregnancy outcomes has been evaluated using various measurement techniques and impedance indices, Aim and objectives; to determine the clinical value of first trimester uterine artery Doppler indices in the prediction of early preeclampsia, Subjects and methods of determining A cross-sectional study of 60 pregnant women from Banha University's Obstetrics & Gynecology Department or inpatient Banha University Hospital was performed. In terms of previous pre-eclampsia, there was a statistically significant difference between individuals who were preterm, at term, and without it. Conclusion: First-trimester uterine artery Doppler had higher predictive accuracy than late-onset illness in the identification of early-onset preeclampsia and FGR. Using uterine artery Doppler indexes to predict preeclampsia in women at low risk, the sensitivity ranges from 34% to 76% and the specificity ranges from 83% to 93% This test's poor sensitivity makes it ineffective as a sole disease marker. Preeclampsia and other poor pregnancy outcomes may be better detected using multiparametric models in the first trimester, according to increasing data.
