Vaginal delivery after cesarean section: a five-year study

All pregnancies that were complicated by a previous cesarean section were reviewed for a five-year period from 1978 to 1982. Of 799 such pregnancies, 216 underwent a trial of labor, and 66% experienced successful vaginal delivery. When the primary cesarean section was for cephalopelvic disproportion, 54% delivered vaginally, 75% breech, and 70% for fetal distress or other nonrepeating indications. There was no evidence of uterine scar disruption in the vaginally delivered group. Vaginal delivery after previous cesarean section can be a safe alternative for carefully selected patients cared for in the proper environment.
