What this trial studies

This study involves women with a twin pregnancy where the presenting twin is not in a head-down position. Participants will undergo an external cephalic version (ECV) procedure to attempt to turn the non-vertex presenting twin to a vertex position before delivery. The study aims to assess the effectiveness and safety of this intervention in improving delivery outcomes for these pregnancies. The focus is on women who are at term and have not had a previous cesarean delivery.

Who should consider this trial

Good fit: Ideal candidates are multiparous women aged 18 or older with a dichorionic diamniotic twin pregnancy at term and a non-vertex presenting twin.

Not a fit: Patients who are nulliparous or have a monochorionic diamniotic pregnancy may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could reduce the need for cesarean deliveries in twin pregnancies with a non-vertex presenting twin.

How similar studies have performed: Other studies have shown that external cephalic version can be effective in improving outcomes for singleton pregnancies, but its application in twin pregnancies is less established.
