800: The significance of a previous uterine scar dehiscence on subsequent births

      Objective

      To determine whether women with a previous uterine scar dehiscence have a higher risk of adverse perinatal outcomes in subsequent births.

      Study Design

      We retrospectively compared all subsequent singleton cesarean deliveries (CD) of women with a previous documented uterine scar dehiscence, with recurrent CD of women with no such history, during the years 1988-2011.

      Results

      Out of 5635 singleton with recurrent CD that occurred during the study period, 3.2% (n=180) were of women with a previous uterine scar dehiscence. Uterine scar dehiscence was significantly associated with subsequent peripartum hysterectomy and preterm delivery (<37wks). However, pregnancies following a previous uterine scar dehiscence were not found to be at an increased risk for uterine rupture, placenta accreta or adverse perinatal outcomes such as low Apgar scores at 5 minutes , low birthweight (<2500gr) and perinatal mortality (Table).

      Conclusion

      In our population, uterine scar dehiscence is not a risk factor for subsequent uterine rupture, placenta accreta or perinatal mortality. However, uterine scar dehiscence is a risk factor for peripartum hysterectomy in the following pregnancy.
