History-indicated cerclage versus ultrasound cervical length screening in women with a history of one extremely preterm birth: A comparative observational cohort study.

Key Points

• To compare the effectiveness of history-indicated cerclage versus ultrasound cervical length screening in reducing preterm delivery risk in women with a past extreme preterm birth.
• Conducted a comparative observational cohort study
• Included women with a history of one extreme preterm birth
• Analyzed outcomes based on intervention type (cerclage or screening)
• History-indicated cerclage was associated with lower risk of delivery before 34 weeks compared to ultrasound screening
• Demonstrated a significant reduction in preterm delivery rates for those receiving cerclage
