ECV
Also written as: ECV — External Cephalic Version
External cephalic version: manual manipulation to turn a breech fetus to vertex presentation.
Full Definition
External cephalic version (ECV) is a manual procedure performed to convert a breech or transverse fetal presentation to vertex (head-down) presentation before delivery. The procedure involves external manipulation of the maternal abdomen to rotate the fetus, typically performed between 36-37 weeks of gestation. ECV is usually attempted under continuous fetal heart rate monitoring and may be facilitated with tocolytic medications to relax the uterus. Success rates vary from 30-80% depending on factors such as fetal weight, amniotic fluid volume, and maternal body habitus. The procedure aims to avoid cesarean delivery for malpresentation, though it carries small risks including placental abruption, cord accidents, and emergency cesarean delivery.
Usage
Usage note: Distinguish from internal version, which is rarely performed and more invasive.
