What does placenta accreta refer to?

Placenta accreta specifically refers to the condition where the placenta adheres abnormally to the myometrium, which is the muscular layer of the uterine wall. In this condition, the placental villi attach too deeply into the uterine tissue but do not penetrate beyond the muscle layer, leading to a risk of severe complications during delivery, such as hemorrhage. This adherence can occur as a result of previous uterine surgeries, like cesarean sections, or other uterine scarring.

The significance of recognizing placenta accreta lies in its potential complications, particularly during labor and delivery, where the placenta may not separate normally. Proper identification of this condition allows for better management strategies to minimize maternal and neonatal risks. Understanding the physiological implications of this abnormal placental attachment significantly aids in prenatal care and planning for delivery.
