external cephalic version
Manual technique to turn a breech or transverse fetus to vertex presentation through external manipulation.
Full Definition
External cephalic version (ECV) is a procedure performed to manually turn a fetus from breech or transverse presentation to vertex (head-down) presentation by applying pressure to the maternal abdomen. The technique involves grasping the fetal head and buttocks through the abdominal wall and gently rotating the fetus. ECV is typically performed between 36-37 weeks of gestation and requires continuous fetal heart rate monitoring. Success rates vary from 30-80% depending on various factors including parity, fetal size, and amniotic fluid volume. The procedure aims to increase the likelihood of vaginal delivery.
Usage
