Placenta Praevia, Placenta Praevia Accreta and Vasa Praevia: Diagnosis and Management

Natural history of vasa previa across gestation using a screening protocol.

OBJECTIVES The purpose of this study was to estimate the prevalence and persistence rate of vasa previa in at-risk pregnancies using a standardized screening protocol.
