Placenta accreta

Placenta accreta (accretio) is the attachment of its edge to the wall of the uterus, due to which it increases in size. Such education can be partial or complete. The enlargement of the organ allows maternal blood, saturated with carbon dioxide and other metabolic products, to leak into it.

Formation can be:

external; internal; mixed. With an external placenta, its outer edge “extends” onto the wall of the uterus. The inner leaf is preserved inside it. The amazing cuff is divided into two ears at the attachment points. One of them - the upper one - is directed inward, the second - the lower one towards the myometrium. As the fetus develops, the size of the placenta increases and can lead to cervical atresia (a pathological process of narrowing of the opening).

With the internal type of formation, the outer edge is not attached to the decidual tissue or myometrium. A twisted location of the placenta around the axis of the attachment site is characteristic. There is a significant amount of blood underneath.

The chorionic folds form cuffs at the bottom of the internal attachment area and on one of the edges on the mi side
