The aim of this study was to determine the perinatal outcomes of placental abruption associated with the presence of histological chorioamnionitis. We reviewed the obstetric records of 96 singleton deliveries complicated by placental abruption after 22 weeks' gestation. Of these 96 cases, 37 cases (39%) were diagnosed as having histological chorioamnionitis in the placenta. The incidence of premature delivery, preterm rupture of the membranes and low birth weight in the cases of placental abruption with chorioamnionitis were higher than in cases without chorioamnionitis. However, there were no significant differences in the incidence of other outcomes, such as fetal demise, low Apgar score, or low umbilical artery pH, between the cases of placental abruption with and without histological chorioamnionitis. Although the incidence of prematurity in the cases of placental abruption with chorioamnionitis was higher than that in cases without chorioamnionitis, there were no significant differences in fetal and neonatal conditions between the abruption cases with and without chorioamnionitis.
