Determinants of Success and Complications in Vaginal Birth After Cesarean Section: A Systematic Literature Review

Trial of Labor After Cesarean (TOLAC) is the process of attempting a vaginal delivery after a prior cesarean section. TOLAC offers an alternative to repeat cesarean delivery but requires careful assessment of risks and benefits. This research aims to evaluate the factors affecting VBAC success and associated risks, providing guidance for clinical practice in determining VBAC eligibility. Relevant literature on VBAC was sourced from databases such as PubMed and Cochrane Library using the keywords "VBAC," "VBAC success," and "VBAC risks." Literature searches for these articles are conducted through databases of scientific journals such as PubMed and Google Scholar. Analysis was conducted to assess predictive factors for VBAC success, including previous vaginal delivery history, cervical conditions, and other parameters. VBAC success is significantly influenced by previous vaginal delivery history, cervical conditions at admission, and factors such as BMI and interpregnancy interval. The main risk associated with VBAC is uterine rupture, occurring in approximately 0.2–0.9% of cases. Proper management and careful risk assessment can minimize complications. VBAC can be a safe and effective option for women who meet specific criteria. Adequate monitoring and assessment are crucial to minimize risks and enhance success rates. Individual evaluation and thorough planning are essential for achieving optimal delivery outcomes. The decision to implement VBAC should be made with careful consideration of the benefits and risks to ensure safe and optimal outcomes for both mother and baby.
