Purpose: External cephalic version (ECV) is an effective procedure to reduce the breech presentation at term reducing the chances of cesarean section. However even after successful ECV reports suggests the risk of having a cesarean section is high. The study analyzes the mode of delivery after a successful ECV and to identify the factors associated with intrapartum cesarean delivery compared to those with spontaneous cephalic presentation.
Methods: This study was based on labor and delivery details, from the ECV registers, of 430 women who had successful ECV and they compared to those with spontaneous cephalic presentation. Primary outcome was delivery by cesarean section. Multiple logistic regression model was used to assess independent association of frisk factors associated with intrapartum cesarean section delivery by cesarean section and were presented as Odds Ratio (OR) and 95% confidence interval.
Results: Cesarean section rates were similar among those who had a successful ECV and those with spontaneous cephalic presentation (22.3% vs 20.1%, p = 0.298). Women who had a successful ECV (OR = 1.5; (95%CI 1.13-1.98), maternal age (OR1.06-1.03-1.09), and previous delivery by cesarean section (OR = 5.16 (95%CI; 1.88-14.16) were found to associated with intrapartum cesarean section after adjusting for other factors.
Conclusion: Women who had a successful ECV had an increased risk of intrapartum cesarean section compared those women with spontaneous cephalic presentation. Further research should be performed to identify more risk factors, which could optimize intra-partum care to reduce the risk of cesarean section for women after successful ECV.
