Background: High-risk pregnancies are associated with a number of adverse perinatal outcomes. Doppler ultrasonography has shown to be a valuable obstetric technique for over 30 years. Aim: The purpose of this study is to ascertain the role that color Doppler plays in the prenatal diagnosis of both high-risk and low-risk pregnancies. Methods: 216 pregnant women participated in a one-year retrospective observational study that was carried out on women between the ages of 20 and 40 who were carrying a singleton pregnancy with a gestational age of 26 weeks to term were included in the study. The study model included both normal variations and some fetal abnormalities. Both mother uterine arteries, the umbilical artery, and the fetal middle cerebral artery (MCA) were imaged using Doppler. Records were kept of the obstetric history and the delivery. Regular checks were performed on the patients. Result: color 216 pregnant women with a single fetus at 26 weeks were evaluated using a Doppler scan. The prevalence of high-risk pregnancies was higher among women aged 31 and above. Pregnancy-induced hypertension was the most prevalent high-risk factor throughout pregnancy.Anomalies were discovered in 75 fetuses out of 216 Doppler images. Fifteen of the fetuses died before term, while sixty survived. A prenatal color Doppler scan showed that there were eight (10.66%) occurrences of intrauterine growth retardation and a diastolic notch in the uterine artery.Out of all abnormality scans, cardiac dysrhythmia was determined to be the least common, at 3 (4%). Conclusion, Doppler is a valid diagnostic technique for identifying fetal abnormalities in high-risk pregnancies. It offers helpful direction and prompt action to enhance fetal outcomes.
