Abstract

Background: Approximately 15-20% of the pregnancies are terminated by miscarriage. Yolk sac first appears at about 5 weeks gestation and is visualized by ultrasound and embryonic heart rate can be used as prognostic factors for first trimester pregnancy outcome, Aim of the study: to evaluate the usefulness of transvaginal ultrasound-determined yolk sac diameter& shape that twill be measured between 6 and 8 weeks of gestation in predicting the outcome of the first trimester pregnancy. Patients and methods; This is a cross sectional study, was conducted at El- Sayed Galal Hospital of Al-Azhar University and Kafr El-Sheikh General Hospital on 100 pregnant ladies were attended antenatal care visits, during the period from April 2021 till the end of the study. Result; yolk sac diameter at in different gestational ages were significantly lower among good outcome group compared to abortion group. Conclusion: Yolk Sac Diameter and Shape Via Transvaginal Ultrasonography can be used as prognostic factor of First Trimester Pregnancy Outcomes. Thus, in the era of artificial reproductive techniques, this parameter may be used as good tool in clinical practice to predict whether a pregnancy is going to have a good or a poor outcome. Further studies are needed to confirm the present findings.
