The placenta begins to form in the first weeks of pregnancy. Normally, it attaches to the uterine wall, but if it attaches abnormally, it is called placenta accreta. There are three forms of placenta accreta, classified based on how deeply the placenta embeds; in most cases, embedding deeper leads to more severe complications. According to the American Pregnancy Association, about one out of every 2,500 pregnancies is affected by some form of placenta accreta.
Placenta accreta is considered a high-risk pregnancy complication, and the issue is most critical during and after delivery. Because the placenta is so deeply attached, it does not detach after childbirth as it would in a normal pregnancy. This drastically increases the risk of severe blood loss after delivery.
