title: [Cord accident after external cephalic version: Reality or mostly myth?]
abstract: OBJECTIVE
  To study the occurrence of cords accident (nuchal cords, prolapse, and braces) after external cephalic version according to its failure or success.
  
  
  METHODS
  Retrospective study between 1998-2015 comparing in the cord accident diagnosed at delivery (by midwife or doctors according to mode of delivery): Patients with attempt ECV: Group 1 cephalic presentation after successful ECV with trial of labor, and Group 2 failed ECV followed by elective cesarean or trial of labor. Patients with no attempt ECV Group 3 spontaneous cephalic presentation matching for delivery date, maternal age, parity, body mass index, and delivery history with group 1, Group 4 Breech presentation without attempt ECV with trial of labor.
  
  
  RESULTS
  A total of 776 women with breech presentation were included (198 in group 1, 446 in group 2, 396 in group 3 and 118 in group 4). The prevalence of cord accident did not differ according to ECV attempt (17.08 % versus 18.9 %), to cephalic presentation (group 1: 24.7 % versus group 3: 25 %) and to breech presentation (group 2: 16.9 % versus group 4: 17.2 %). The trial of labor after failed ECV did not increase the risk of cord accident when compared with elective cesarean (17.4 % versus 16 %). A prolapse cord was only observed after trial of labor, i.e. in groups 1, 2 and 4 without difference (respectively 1, 0.8 and 1.7 %). In each group, the rate of cesarean was not different according to the presence of nuchal cord.
  
  
  CONCLUSIONS
  Success or failed External cephalic version is not associated with an increased risk of cord accident.
