Ultrasound Parameters for the Outcome Prediction of External Cephalic Version for Fetuses with Breech Presentation

"before ECV procedure, an ultrasound will be performed to evaluate~* fetal biometry (BPD, HC, AC, FL, EFW);~* Occiput position (right, left);~* Back position (anterior, posterior, right, left);~* Breech variant (footling, frank, complete);~* Fetal leg posture (extended, flexed)~* Placental localization;~* Amniotic Fluid Index (AFI);~* Fore-bag of amniotic fluid;~* Eventual presence of nuchal cords;~* Fetal head ballottement (yes, no);~* Occiput-spine angle These parameters will be compared to find predictive factors for successful ECV"
