Assessing factors for successful external maneuvers in breech pregnancies

Prediction of Version Outcomes for External Maneuvers of Breech Fetus by Assessment of Breech Progression Angle (breech Progression Angle)

Observational IRCCS Azienda Ospedaliero-Universitaria di Bologna · NCT06816563

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.

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.

Who should consider this trial

Good fit: Ideal candidates are women over 18 years of age with a single breech pregnancy at term.

Not a fit: Patients with conditions such as oligohydramnios, placenta previa, or contraindications to vaginal delivery may not benefit from this study.

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 performed: Previous studies have shown varying success rates with similar ultrasound-based approaches to assess breech presentations, indicating potential for this methodology.
