Yolk sac size and shape, Gestational sac size, and embryonic Heart Rate as prognostic factors of first trimester Pregnancy Outcome.

Abstract

Background; Around 15-20% of pregnancies end in miscarriage. The yolk sac initially forms at around 5 weeks gestation and may be viewed via ultrasonography. Both the yolk sac and fetal heart rate can be utilized as predictors of first trimester gestation result, Aim and objectives; to determine the relationship between early abortion and each of the ultrasound characteristics measured during the first trimester (gestational sac size, yolk sac size, and fetus heart activity). Subjects and methods; This prospective cohort research was done on 200 pregnant women in their first trimester with a week of gestation of between 5 and 6 weeks at Al-Azhar University's department of obstetrics and gynecology. Result; According to the ultimate conclusion of ultrasonographic findings in the study group, 5 (2.5%) of the 34 fetus losses were missed abortions (fetal pole without detectable pulsations), 10 (5%) were blighted ovaries, 7 (3.5%) were partial miscarriages, and 12 (6%) were complete miscarriages. conclusion; During the first trimester of pregnancy, the monitoring of these characteristics (FHR, YS diameter and shape, and GS diameter) proven to be a great, useful, and non - invasive tool in the evaluation, prognosis, and follow-up of pregnant women. When the gestational sac diameter, CRL, and embryo heart rate were recorded all at the same time, they were able to determine the prognosis of the first trimester better than when each characteristic was used separately.
