Versión cefálica externa en presentación de nalgas: una técnica ancestral muy actual

Breech presentation occurs in 3-4% of pregnancies and is a routine indication for cesarean section. The external version is a maneuver that has been performed since Hippocrates' time. Nevertheless, despite decreasing the cesarean section rate, this technique is only offered to a small percentage of patients due to lack of awareness and the shortage of experienced obstetricians. The success rate ranges from 40-74%. Factors that can influence the success of the maneuver are gestational age, the amniotic fluid index, presentation, and the location of the placenta. The use of tocolytics and effective analgesia can facilitate the maneuver and improve the success rate. When a standardized protocol is followed and the technique is performed by an experienced gynecologist, the external cephalic version has an excellent safety profile and is an effective option that avoids surgery.
