title: Vaginal delivery after Caesarean section: factors influencing success rates.
abstract: In a retrospective review of 333 pregnancies in women who had 1 previous Caesarean section, 244 (73.3%) underwent a trial of scar, and 89 (26.7%) had an elective Caesarean section. In the trial of scar group 197 (80.7%) had a vaginal delivery and 47 (19.3%) required an emergency Caesarean section. The success of the trial was favourably influenced by a nonrecurring indication for the original Caesarean section, a previous vaginal delivery, and a smaller baby. Maternal morbidity was greater in the groups requiring a Caesarean section, whether elective or emergency. Those patients delivered vaginally spent significantly less time in hospital. In 2 of the 244 patients (0.8%) who underwent a trial of scar the previous lower segment scar was found at Caesarean section to have dehisced or ruptured.
