Abstract
Background: Threatened abortion is assumed clinically when, during the first half of pregnancy, a bloody vaginal leak or bleeding through a closed cervical os occur. Around half of these gestations will terminate, and the risk of abortion is significantly smaller if the cardiac activity of the fetus is imagined.
Aim and objectives: We aimed to evaluate the role of greyscale and color Doppler ultrasonography in the early detection of threatened abortion.
Patients and methods: This study was performed prospectively during the period from December 2018 to May 2019 at Zagazig University Hospital and Zagazig General Hospital. The study was carried out on 60 pregnant women divided into two groups; one group had vaginal bleeding, and the other group had an uncomplicated pregnancy.
Results: We detected a statistically significant increase in both uterine artery resistance index (RI) and trophoblastic flow RI; moreover, a statistically significant decrease regarding fetal heart rate (FHR) among Group A compared to Group B was observed (all P
