Miscarriage is the most typical early pregnancy complication and a significant clinical problem even today. The etiology of this illness is poorly understood, and as a result, therapy regimens are based on scant evidence. The study objective was to assess the role of retro-chorionic blood flow doppler in early prediction of first trimester miscarriage. This prospective cohort study was carried out at a major medical center at the department of obstetrics & gynecology at Al Sayed Galal University Hospital from June 2022 till March 2023 and performed on total 100 patients who presented with singleton pregnancy and gestational age from 6 to 10 weeks. Our results revealed that clearly distinct differences emerged between the studied population regarding (Pulsatility index (PI), Resistance index (RI) and Systolic/diastolic (S/D) ratio according to abortion), (Resistance index (RI) regarding Correlation between week of abortion and Spiral Arterioles Doppler Ultrasound findings) and Diagnostic performance of Spiral Arterioles Doppler Ultrasound findings in predicting abortion. We concluded that in early pregnancy (between 6 and 8 weeks), Spiral artery doppler analysis may provide a non-invasive indicator of insufficient trophoblast invasion as a screening test for early prediction of miscarriage.
