Abstract

Background: Miscarriage is a common event in the first half of pregnancy. Improvements in Ultrasound and Doppler technology, have led to a better understanding of early pregnancy development. Such a facility may be used in turn to predict pregnancy outcome in threatened miscarriage.
Objective: To assess the ability of the Uterine artery RI and Spiral artery RI to predict outcome in cases of Threatened miscarriage
Patients and methods: Prospective observational study was conducted in the Department of Obstetrics and Gynecology at Menoufia University Hospital. The study included 90 women with gestational age between 5 – 13 w. divided into three groups; Group (A): involved (30) women diagnosed with threatened miscarriage and was followed up and got aborted before pregnancy completed 24weeks. Group (B): (30) women diagnosed with threatened miscarriage and were followed up and the pregnancy continued till 24weeks. Group (C): 30 women having singleton normal ongoing pregnancy till 24 weeks of gestation as a control group.
Results: In this study, the Doppler study of uterine arteries the subchorionic blood flow revealed that (RI) was significantly higher in the miscarried group than both continued and control groups.
Conclusion: Uterine artery RI and Subchorionic blood flow RI can predict the fate of pregnancy in cases with threatened miscarriage with high accuracy.
