What is Placenta Accreta?

Placenta accreta spectrum (PAS) is a pregnancy complication that occurs when the placenta attaches too deeply into the wall of the uterus. The risk for developing accreta increases with each C-section or uterine surgery. Placenta accreta puts the mother at risk of severe blood loss and other complications. The rates of maternal death, transfusion, prolonged hospital stay and hysterectomy are all increased for women with accreta.
