[Vaginal birth after cesarean. A safe option?].

Area of Science:

• Obstetrics and Gynecology
• Reproductive Medicine

Context:

• Vaginal birth after cesarean (VBAC) is a critical consideration for women with prior cesarean deliveries.
• Evaluating the safety and success factors of VBAC is essential for informed clinical practice and patient counseling.

Purpose:

• To compare labor onset and evolution variables in patients undergoing vaginal birth after cesarean (VBAC).
• To analyze demographic characteristics, obstetric, and perinatal outcomes in VBAC patients.
• To identify factors influencing successful VBAC.

Summary:

• This retrospective study analyzed 136 patients eligible for VBAC, with 78% experiencing spontaneous labor onset.
• Key demographic factors associated with successful VBAC included higher parity, previous vaginal delivery history, higher Bishop score, lower estimated fetal weight, and longer interpregnancy interval.
• Perinatal outcomes were positive, indicating VBAC is a safe option.

Impact:

• VBAC should be offered to women with a low transverse incision, interpregnancy interval >18 months, singleton pregnancy, cephalic presentation, appropriate fetal weight, and no contraindications.
• This research supports shared decision-making in childbirth options for women with prior cesarean sections.
• Findings contribute to evidence-based guidelines for managing labor in women with previous cesarean deliveries.
