Bakcground: Caesarean section is the main proceedings for ending of pregnancy in the world, and currently represents a public health problem. Some factors that benefit the likelihood of vaginal birth after a previous C-section have been described in literature, with scoring tools designed to predict success for trial of labor after a previous cesarean. There are few studies that identify predictors of success for vaginal delivery in Latin-American patients. Objective: To identify predictive factors associated to vaginal delivery success in patients with a prior cesarean delivery. Material and method: Case-control study. We included patients with one previous cesarean delivery admitted at our hospital. The variables analyzed with a logistic regression system to predict vaginal delivery success probabilities. Results: A total of 1160 patients were included, 668 underwent C-section (considered control group), and 492 patients had a vaginal delivery (considered study group). The Factors associated to vaginal birth after cesarean delivery were maternal age (25.1±5.4 vs 24.7±5.5 years old, OR 0.967, p<0.05), fetal weight (3,253±389 vs 3,383±452 g, OR 0.99, p<0.05), previous vaginal delivery (49 vs 18.4%, OR 2.97, p<0.05) and spontaneous labor (90.8 vs 74.1%, OR 3.68, p<0.05, respectively). Conclusion: Maternal age, fetal weight, previous vaginal delivery and spontaneous labor were associated with vaginal delivery success in patients with a previous cesarean delivery.
