Background: The predominant obstetric condition causing significant foetal and mother mortality in the Kurdistan region/Iraq is preeclampsia. The aim of research is to assess if Doppler ultrasonic indices can predict unfavorable perinatal outcomes of preeclampsia. Patients & method: On a sample of 35 pregnant women with preeclampsia and 35 health pregnant women, a case control research carried out in Maternity Teaching Hospital and private hospital in Duhok City-Kurdistan region/Iraq for a period of eight months from 1st of January, to 31st of August, 2024. After twenty weeks’ gestation in pregnancy with one or more of (protein-urea and high blood uric acid), the preeclampsia was classified as new-onset hypertension. Three days following birth, the investigated women were monitored in order to evaluate their perinatal outcomes. Results: P≤0.05 Doppler indices for umbilical and uterine arteries of women with preeclampsia were much higher than those of controls. Women with preeclampsia had notably lower Doppler indices for middle cerebral artery than did controls (p≤0.05). Among preeclampsia women with early newborn mortality and intrauterine death, the mean uterine artery Doppler indices were noticeably higher (p≤0.05). Conclusions: For pregnant women with preeclampsia, the Doppler ultrasonic indices are quite excellent predictors of poor newborn outcomes.
