Placenta accreta can cause serious complications, including:

  • Heavy vaginal bleeding. Placenta accreta poses a major risk of severe vaginal bleeding (hemorrhage) after delivery. The bleeding can cause a life-threatening condition that prevents your blood from clotting normally (disseminated intravascular coagulopathy), as well as lung failure (adult respiratory distress syndrome) and kidney failure. A blood transfusion will probably be necessary.
  • Premature birth. Placenta accrete might cause labor to begin early. If placenta accreta causes bleeding during your pregnancy, you might need to deliver your baby early.
