Objective: To raise the success rate of vaginal birth after cesarean (VBAC) without increasing maternal or perinatal morbidity and mortality rates.Methods: Of 468 women with a prior scar, 365 gave valid informed consent for our management of VBAC at Akashi Municipal Hospital during 1986–1999. Trials of labor (TOL) were attempted in 322 cases principally by waiting for spontaneous labor onset and teaching the patients a breathing method to avoid straining until expulsion by vacuum extraction become possible, controlling the intrauterine pressure. Our selection criteria for TOL changed during the trial; from 1991–1999 patients with a prior scar extending into fundus were excluded.Results: Of the 322 TOL, 88.2% were successful, and VBAC was successful in 77.8% (284 of the 365 patients). Uterine rupture was observed in 2 cases (0.62%). Fetal death occurred in 1 case. Three women gave birth to neonates with a 1‐minute Apgar score ≤6.Conclusion: The rate of VBAC was 77.8% in all women with a prior scar. During our management of VBAC, maternal or perinatal morbidity and mortality rates did not increase significantly.
