**1. Introduction**

Vaginal birth after cesarean (VBAC) is defined as a vaginal delivery by a woman who has had a previous cesarean delivery [1]. When women receive support to undergo a VBAC, numerous advantages arise for the women themselves, their families, and society as a whole. Opting for a vaginal birth can result in swifter post-birth recovery, reduced surgical trauma, shorter hospital stays, and enhanced overall well-being, encompassing physical and psychological aspects for women [2]. VBAC is associated with lower maternal mortality and less overall morbidity for mothers and

babies [3]. It is well-known that C-section now, hysterectomy complications later. In cases where women had previously delivered through cesarean section, the likelihood of encountering surgical complications increased during hysterectomy procedures. According to a comprehensive Danish cohort study that looked back at past records, women with a history of C-section had elevated rates of reoperation within 30 days and experienced more perioperative and postoperative complications when undergoing a benign hysterectomy compared to women who had delivered vaginally [4].

This review aims to explore the existing research on VBAC to provide a background and purpose to this paper. The review encompassed a range of research methodologies, including qualitative and quantitative approaches. It begins by examining women's attitudes and perspectives toward VBAC, along with investigating VBAC education and the decision-making process for choosing the mode of birth. The study identifies various factors that contribute to achieving a VBAC, which are further categorized into sub-themes. Furthermore, the review delves into the morbidity and mortality risks associated with cesarean sections, as well as comparative studies comparing the risks and outcomes of VBAC versus cesarean deliveries. Additionally, the review places emphasis on the outcomes of VBAC births that occur outside of hospitals, the management of VBAC within hospital settings, and the existing research on birth trauma. Within the topic of birth trauma, the review explores women's emotional experiences related to their previous traumatic births, including some that involved cesarean sections, and also highlights the potential healing effects of a positive subsequent birth.
