Prediction of preterm birth using 3D volume cesarean scar morphology in pregnant women with previous advanced labor cesarean delivery

Key Points

• The research aims to explore the effectiveness of 3D ultrasound in predicting preterm birth based on cesarean scar morphology.
• Conducted 3D transvaginal ultrasound assessments on pregnant women with previous advanced labor cesarean delivery.
• Analyzed the morphology of cesarean scars to assess their relation to preterm birth prediction.
• Examined the relationship between scar position relative to the internal os and spontaneous preterm birth.
• 3D ultrasound assessment significantly improved prediction accuracy for spontaneous preterm birth.
• Scar position relative to the internal os was identified as the strongest individual predictor.
