👉 In obstetrics and gynecology, an "extraplanatic" delivery refers to a vaginal birth that occurs outside of normal pregnancy. This can occur at any stage of pregnancy, but it is most common in early-term pregnancies, typically around 18-24 weeks gestation. The term "extraplanatic" comes from the Greek word for "outside," which implies that the baby has been born through a process not involving an external birth canal or umbilical cord.
