Background & Objective: Preeclampsia (PE) is a major complication of pregnancy worldwide. Doppler ultrasound of maternal arteries, including uterine and ophthalmic arteries (OA), plays an important role in determining individuals progressing PE. The aim of this study is to compare OA indices in pregnant women with a diagnosis of PE and women without it.Materials & Methods: This study evaluated pregnant women who had delivery in Shariati Hospitals, Tehran, Iran between January 2021 and March 2022. The maternal OA Doppler waves were obtained in preeclamptic and non-preeclamptic women at 35 to 37 weeks of gestation by a maternal-fetal medicine specialist. OA Doppler parameters including first and second PSV, second to first PSV ratio (Peak ratio, PR) and PI were obtained for each eye and also average between the eyes.Results: Out of 148 included participants, 48 cases progressed to PE at 35 to 37 weeks of gestation and 100 cases did not have PE at the same gestational age. All OA parameters including (First and second peak systolic velocities (PSV), second to first PSV Ratio (PR) and Pulsatility Index (PI) in each eye; as well as, the average of these indices in both eyes) were assessed. PR and PI between the two eyes were statistically different in those with PE.Conclusion: OA Doppler indices change in pregnant women with PE. These changes could help to earlier and better diagnosis of PE and prevention of maternal and fetal sequelae.

Background & objective: Premature preterm rupture of membrane (PPROM) is a cause of preterm birth. This study investigated the effectiveness of Doppler ultrasound in predicting fetal complications and neonatal outcomes of pregnant women with PPROM.Materials & Methods: In this cross-sectional study, a total of 23 pregnant women with PPROM were chosen in their 24 to 34 weeks of gestational age. The fetuses’ blood flow indices were evaluated by Doppler ultrasound pulsatility index (PI) in the middle cerebral, main pulmonary, right kidney, and fetal umbilical arteries and descending aorta at admission (because of PPROM) and 24 hours before delivery. Neonatal outcomes were assessed within the first week of birth.Results: The kidney artery PI increased (P < /em>=0.047) and pulmonary artery PI decreased (P < /em>=0.024) at pregnancy termination time. There was a negative correlation between the 5-minute Apgar score and fetal umbilical artery PI at admission (P < /em>=0.003) and pregnancy termination times (P < /em>=0.031). The fetal umbilical artery PI of neonates with abnormal brain ultrasound imaging results significantly decreased at admission (P < /em>=0.002) and pregnancy termination times (P < /em>=0.004).Conclusion: Fetal artery Doppler ultrasound PI may be a valid tool for predicting neonatal outcomes of women with PPROM.
