Impact of the external cephalic version on the obstetrical prognosis in a team with a high success rate of vaginal delivery in breech presentation

Objectives.- To analyse the impact of external cephalic version (ECV) on caesarean section rate in a team with a high success rate of vaginal delivery in breech presentation. Materials and methods.- Retrospective monocentric study including 298 patients with a breech presentations between 33 and 35 weeks of annenorrhea followed at our university hospital and delivered after 35 weeks, between 1stJanuary 2011 and 31st December 2013. Patients were divided `into-2 groups: planried ECV (n=216 patients) versus no-Planned CV (n=57 patients). Results.- Our rate of successful vaginal breech delivery over the period of the study was 61.1%. We performed 165 ECV, with a 21.8% success rate. The average term of the attempt of ECV was 36.7 weeks of amenorrhea. The caesarean section rate was not significantly different in the planned ECV group, even after adjustment on age, parity and previous caesarean delivery (adjusted OR= 1.67 [0.77-3.61]). Attempt of ECV did not reduce the number of breech presentation at delivery (61.1% versus 61.4% [P=0.55]). Conclusion.- Planned ECV in our center with a high level of breech vaginal delivery did not significantly impact our cesarean section rate. (C) 2016 Elsevier Masson SAS. All rights reserved.
