What complication involves the placenta invading the myometrium?

The complication that involves the placenta invading the myometrium is known as placenta increta. In this condition, the placenta attaches too deeply into the uterine wall, specifically penetrating into the myometrium but not through it. This abnormal attachment can lead to difficulties during delivery, as the placenta may not separate easily from the uterine wall, potentially causing significant bleeding and necessitating careful management.

Increments of invasion include milder forms such as placenta accreta, where the placenta adheres to the uterine lining without invading the myometrium, and more severe forms like placenta percreta, where the placenta invades not only the myometrium but also perforates through the uterine wall and can invade surrounding structures. Understanding the nuances of these conditions is crucial for appropriate prenatal management and planning for delivery, as each type presents different risks and implications for maternal and fetal outcomes.
