Background: In early ultrasonography, pregnancies with a mean yolk sac diameter of equal to or more than 5 mm are also linked to a threefold increased risk of miscarriage in the first trimester. Understanding the predictive value of yolk sac diameter in cases of miscarriage can aid in improving risk assessment and patient management in early pregnancy.
Aim of the study: This study aimed to investigate the predictive value of yolk sac diameter with transvaginal ultrasound in cases of miscarriage.
Patients and Methods: This prospective study included 112 women in early pregnancy undergoing ultrasound assessment for various indications. Yolk sac diameter measurements will be obtained and correlated with pregnancy outcomes, focusing on the occurrence of miscarriage.
Results: There was a statistically significant difference among the study groups with respect to the location of the GS, the relationship amongst yolk sac size, shape, and/or echogenicity and abortion, the validity of each Yolk Sac abnormality in predicting abortion, & the accuracy of YS in predicting abortion.
Conclusion: The current investigation demonstrated a statistically significant rise in the probability of abortion among instances with an abnormally large yolk sac size, a missing yolk sac, and a hyperechogenic center. Furthermore, the results of this study demonstrated that The best cut off value for prediction of abortion was <2 & >6 with the sensitivity of the YS abnormality in the predication of abortion was 88%., specificity 76%, accuracy 82%.
