Abstract
PURPOSE: To define the effects of attempted external cephalic version (ECV) in a low-risk population for breech delivery in a maternity hospital where breech vaginal delivery is widely practiced. MATERIALS AND METHODS: Retrospective exposed-unexposed study including 204 patients presented with a live singleton fetus breech presentation on third-trimester ultrasound and who delivered at Reims University Hospital between January 1st, 2013 and July 1st, 2018. RESULTS: 121 patients received ECV. Cesarean section rate was lower (OR with no adjustment 0.42 [0.24-0.76] p = 0.004) but without significant difference in the exposed patients after adjustment. This difference was significant between exposed and unexposed patients in the subgroup of 51 primiparous (OR = 0.14 [0.04-0.52] p = 0.002) and 51 multiparous (OR = 0.26 [0.08-0.89] p = 0.028) but not in the subgroup of 102 nulliparous. There was no difference in fetal impact other than neonatal management in the delivery room, which is less needed in exposed primiparous women. Attempted ECV significantly decreased the breech rate (72.5 vs 100%, p < 0.001). There were 7 (5.79%) complications. Three factors favored success: high uterine height (p = 0.011), a non-elevated BMI (p = 0.006) and an earlier term at ECV (p = 0.003). CONCLUSION: The attempt of ECV in the Reims University Hospital does not significantly reduce the Cesarean section rate and has no effect on neonatal status.
