title: Evidence that women with a history of cesarean section can deliver twins safely.
abstract: OBJECTIVE
  To determine whether a trial of labor is safe in twin pregnancies after one previous cesarean section.
  
  
  METHODS
  Retrospective analysis of all cases of multiple pregnancies after cesarean section during the years 1970-1993, including twin gestations after one cesarean section.
  
  
  RESULTS
  Forty-six cases of multiple gestations were found, 36 of which were eligible for the study presented herein. Fifteen women (41.7%) were denied trial of labor. Twenty-one women (58.3%) were allowed trial of labor, 17 (80.9%) of whom were delivered vaginally and four (19.1%) by a repeated cesarean section. The group of trial of labor was compared to the group of elective cesarean section. Hospitalization period was 4.4 +/- 1.9 days and 8.0 +/- 2.6 days in the trial of labor group and elective cesarean section group, respectively (p<0.01). Blood transfusions required were 9.5% and 26.6% in both groups, respectively (NS). Puerperal infections were 9.5% in the trial of labor group, compared to 46.6% in the elective cesarean section group (NS). No scar dehiscence occurred in either groups. There were no statistically significant differences in age, parity, gestational age at delivery, mean newborn weight, Apgar score at one and five minutes, Neonatal Intensive Care Unit admission and mean Neonatal Intensive Care Unit stay.
  
  
  CONCLUSIONS
  Vaginal delivery in twin gestation after one previous cesarean section may be considered in appropriate cases. A large multicentral randomized prospective study may further confirm this conclusion.
