External cephalic version after previous cesarean section: a series of 38 cases

Objective: To determine if external cephalic version (ECV) is a reasonable alternative to repeat cesarean section in case of breech presentation. Study design: Retrospective study of 38 women with one previous cesarean section and a breech presentation after 36 weeks of gestational age who have had at least one experience of ECV. Statistics used the Fisher's test with significance when P<0.05. Results: Version attempts were successful in 25 of the 38 women (65.8%). Seventy-six percent of the successful version women went on to have vaginal birth after cesarean section. A total of 19 successful vaginal deliveries occurred (50%). Success rate of ECV was lowered when breech was the indication of the previous cesarean section. The vaginal delivery rate was increased after successful ECV in patients previously vaginally delivered, but this difference did not reached significance (P=0.057). No maternal or neonatal complications occurred. Conclusion: ECV is acceptable and effective in women with a prior low transverse uterine scar, when safety criteria are observed.
