Summary
Vaginal birth after cesarean delivery is successful for most women. Attempting a vaginal birth after a previous cesarean section (VBAC) is safe and effective, with lower maternal risks.
Area of Science:
- Obstetrics and Gynecology
- Reproductive Health
Background:
- Cesarean section rates have increased globally.
- Previous cesarean delivery is a common reason for repeat cesarean.
- Vaginal birth after cesarean (VBAC) is an alternative delivery method.
Purpose of the Study:
- To evaluate the success and safety of VBAC.
- To determine factors influencing VBAC success.
- To assess maternal and neonatal outcomes in VBAC.
Main Methods:
- Retrospective analysis of 249 women with a history of cesarean section.
- Categorization of delivery outcomes: primary cesarean, VBAC attempt, successful VBAC, and secondary cesarean.
- Correlation analysis of previous cesarean indication with VBAC success.
Main Results:
- 77.1% of women attempted VBAC, with a 60.6% success rate.
- Successful VBAC rates varied based on the indication for the prior cesarean.
- Maternal morbidity was lowest in the successful VBAC group.
- Neonatal outcomes were comparable between successful VBAC and primary cesarean groups.
- One case of incomplete uterine rupture occurred.
Conclusions:
- VBAC is a viable and safe option for selected women.
- The policy of 'once a cesarean section, trial of labor after selection' is supported by evidence.
- Shared decision-making regarding delivery mode is crucial.
