CERVICAL ULTRASONOGRAPHY AS A PREDICTOR FOR VAGINAL BIRTH

Abstract

Transvaginal ultrasonography has emerged as an effective tool for predicting vaginal delivery, particularly through the assessment of cervical length throughout pregnancy. This study aims to analyze, through an integrative literature review, the clinical application of ultrasonography in the early identification of pregnant women at higher risk of preterm birth, as well as in estimating the likelihood of spontaneous labor at term. Anatomical, physiological, and technical aspects of the cervix, along with the main ultrasonographic parameters used in obstetric practice, were explored. Cervical length measurement demonstrated high accuracy in predicting gestational outcomes and is considered a key strategy in the personalization of prenatal care. Despite technical and individual limitations, advances in ultrasonographic technology and the standardization of methods contribute to the improvement of gestational monitoring and the reduction of perinatal risks.
