Assessing factors for successful external maneuvers in breech pregnancies
Official title: Prediction of Version Outcomes for External Maneuvers of Breech Fetus by Assessment of Breech Progression Angle (breech Progression Angle)
Run by IRCCS Azienda Ospedaliero-Universitaria di Bologna · NCT06816563 · Data updated 2026-11-12
This study is trying to see if certain ultrasound measurements can help predict how successful a technique is at turning breech babies into the right position for delivery.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are women over 18 years of age with a single breech pregnancy at term.
✕Probably not a fit
Patients with conditions such as oligohydramnios, placenta previa, or contraindications to vaginal delivery may not benefit from this study.

What this trial studies
This observational study aims to evaluate the effectiveness of external cephalic version maneuvers in breech pregnancies by analyzing various ultrasound parameters. Patients will undergo transabdominal and transperineal ultrasound assessments to measure factors such as breech presentation type, estimated fetal weight, and the Breech Progression Angle. The study will collect data on delivery outcomes, including mode of delivery and neonatal health indicators, to determine the success of the maneuver. The goal is to identify predictors that could improve the chances of a successful version and reduce risks associated with breech presentations.
Why it matters
Potential benefit: If successful, this study could enhance the safety and outcomes of vaginal deliveries for breech-presenting fetuses.
How similar studies have gone: Previous studies have shown varying success rates with similar ultrasound-based approaches to assess breech presentations, indicating potential for this methodology.
