Background: Placenta previa (PP) can cause repeated and
catastrophic bleeding that may lead to increased maternal and neonatal mortality
and morbidity. The purposes of this study were to determine the relationship
between antepartum hemorrhage (APH) and gestational week, the frequency of APH,
the risk factors for APH, and whether patients with APH developed more severe
adverse perinatal outcomes. Methods: This was a multi-center,
retrospective study in which we enrolled all placenta previa patients between
October 2015 and September 2018 within the Partners Healthcare System.
Results: The mean APH frequency was 2.2
