The impact of previous cesarean section on the outcome in patients with non-adherent placenta previa

To evaluate the impact of previous lower segment cesarean section on maternal and fetal outcomes of patients with non-adherent placenta previa This is a retrospective study of all patients who delivered at a tertiary referral university hospital by lower uterine cesarean section with non-adherent placenta previa, over a 10-year period. Data were obtained through hospital registry and medical records. The differences in demographic, obstetric characteristics, peripartum complications, and fetal outcome between patients with no previous cesarean and those with previous cesarean section were analyzed. Ninety patients with non-adherent placenta previa were included, 54 patients with no previous cesarean and 36 patients with previous cesarean section. Patients with previous cesarean section were significantly more likely to incur inadvertent organ injury, transfusion of 4 or more units of packed red blood cells, transfusion of fresh frozen plasma, uterine brace compressive sutures, uterine artery ligation, and peripartum hysterectomy. There is a significant increase in the incidence of inadvertent neighboring viscus injury, transfusion of 4 units or more of packed red blood cells, transfusion of fresh frozen plasma, uterine brace compressive sutures, uterine artery ligation, and peripartum hysterectomy in patients with non-adherent placenta previa and previous cesarean section, compared to those with non-adherent placenta previa and no previous history of cesarean section, with no difference in perinatal outcome.
