The aim is to assess the role of combined uterine artery Doppler & B-hCG in predicting pregnancy related hypertensive diseases & JUGR. to assess the value of determining the ovarian volume by ultrasound and studying Doppler of ovarian vascularity in diagnosis of PCOD.Methods: 46 pregnant females were included; they were subjected to Uterine artery Doppler & measurement of B-hCG at 11-14 weeks gestation.. All pregnancies were followed until 24 weeks for development of preeclampsia and IUGR.Results: cases that developed preeclampsia (compared to those who didn’t develop preeclampsia) already have increased prevalence of unilateral/ bilateral diastolic notching; .higher RI; lower B-hCG levels. All these were of statistically significant difference .Conclusion: combined use of uterine artery Doppler and B-hCG in the first trimester of pregnancy is valuable in predicting development of preeclampsia.
