[Trial of labor after 2 cesarean sections. Prospective study of 130 cases].

The mode of delivery in the parturient women with two prior cesarean is controversial. Based on a prospective analysis of 130 cases, we tried to assess the outcome of trial of labor after two cesarean sections. Among 167 patients with two uterine scars, 130 (77.8%) were selected for a trial of labor that was successful in 65 cases (50%). The overall rate of vaginal birth and cesarean section was 39% and 61%, respectively. There were 4 scar dehiscences and 2 uterine ruptures among the women who underwent trial of labor, but no case of perinatal death or morbidity related to these complications was observed. In the majority of the cases, these scar separations were due to poor obstetrical conditions. Trial of vaginal delivery after two prior cesarean sections seems to us a reasonable attitude if it is well indicated and supervised correctly.
