The purpose of this guideline is to describe the diagnostic modalities used for placenta praevia, vasa praevia
and a morbidly adherent placenta and how they are applied during the antenatal period. Clinical management
will be described in the antenatal and peripartum period with specific reference to the anticipation,
planning and timing of surgery, as well as to the advanced techniques and interventions available for managing
placenta accreta. This guideline does not address the problems of a suspected morbidly adherent placenta
before fetal viability
