What does ECV stand for?

1. Stands for: External Cephalic Version

External Cephalic Version (ECV) is a medical procedure used to turn a fetus from a breech position (feet or buttocks first) to a head-down position before labor begins.

Procedure and Technique

  • Assessment: Ultrasound is used to assess the fetus’s position, amniotic fluid levels, and placenta location.
  • Medication: A muscle relaxant may be administered to the mother to relax the uterus.
