Placenta-Cervical Interface Angle for Predicting Placenta Accreta Spectrum Severity

Sponsor: Necmettin Erbakan University

Summary

Placenta accreta spectrum (PAS) is associated with substantial maternal and neonatal morbidity, and accurate antenatal prediction of its severity remains challenging. Although several sonographic markers exist, most are subjective and operator-dependent, and few predict surgical complexity or adverse perinatal outcomes. This prospective observational cohort study evaluates the Placenta-Cervical Interface Angle (PCIA), a novel geometric transvaginal ultrasound marker, defined as the angle between the longitudinal axis of the cervical canal and the tangent line drawn to the lower placental edge. The study assesses the predictive performance of the PCIA for severe PAS and its association with intraoperative morbidity and adverse perinatal outcomes.
