What best describes placenta accreta?

Placenta accreta is characterized by an abnormal attachment of the placenta to the uterine wall. Specifically, it occurs when the placenta is implanted deeply into the myometrium, which is the muscular layer of the uterus. This improper implantation can lead to various complications, particularly during delivery, as the placenta may not detach easily, increasing the risk of hemorrhage and other serious issues.

Understanding this condition is vital for midwives and healthcare providers, as it requires careful monitoring and potentially surgical intervention during the birth process to mitigate risks to both the mother and baby. Recognizing the specifics of placenta accreta helps in differentiating it from other conditions involving abnormal placental placement, such as placenta previa, where the placenta is located over the cervical opening, or placental abruption, where the placenta detaches from the uterine wall prematurely.
