Which statement about external cephalic version (ECV) is true?

• A. It is offered at 36-37 weeks for singleton breech fetuses
• B. It is always attempted at 39 weeks
• C. It is contraindicated in all pregnancies
• D. It is commonly used to prevent breech births at term

Answer: (A)

External cephalic version is a procedure to turn a breech fetus to head-down presentation from outside the uterus, with the aim of improving the chances for vaginal delivery and reducing cesarean births. In an uncomplicated singleton pregnancy with breech presentation, this option is typically offered around 36 to 37 weeks. This timing gives enough opportunity to plan delivery if the version is successful, while still being close enough to term to avoid a breech labor and to reduce the risk of a spontaneous reversion or complications if done too early. Attempting it at 39 weeks leaves less time to manage potential outcomes and to arrange delivery if needed. It’s not a blanket contraindication for all pregnancies; there are specific situations where ECV is avoided (such as placenta previa, certain uterine scars, multiple gestation, fetal distress, and some placental or structural issues), but in appropriately selected cases it can meaningfully reduce the likelihood of a breech birth at term.
