Clinical analysis of umbilical cord torsion-related prenatal stillbirth

We developed and validated a highly accurate prediction model for UCT-related prenatal stillbirth, identifying a history of decreased or vanished fetal movement, umbilical cord root torsion at the fetal umbilical insertion site, and FGR as the paramount risk factors. Given the profound limitations of conventional ultrasound in prenatal detection, clinical management must undergo a critical shift: from reactive reliance on imaging to proactive management based on maternal symptomatology. Thus, decreased fetal movement should be the primary indicator for urgent assessment, while any sonographic suggestion of umbilical root torsion and FGR should trigger intensified surveillance and delivery planning.
