Obstetric haemorrhage results in a significant proportion of maternal deaths worldwide, and abnormally adherent placenta (AAP), comprising placenta accreta, increta and percreta, is a rare but important cause of haemorrhage.

Placenta accreta is a serious pregnancy condition that occurs when blood vessels and other parts of the placenta grow too deeply into the uterine wall. Typically, the placenta detaches from the uterine wall after childbirth. With placenta accreta, part or all of the placenta remains firmly attached.

This can cause severe blood loss after delivery. It's also possible for the placenta to invade the muscles of the uterus (placenta increta) or grow through the uterine wall (placenta percreta). Placenta accreta is considered a high-risk pregnancy complication. If placenta accreta is suspected during pregnancy, you'll likely need an early C-section delivery followed by the surgical removal of your uterus (hysterectomy).

Placenta accreta is thought to be related to abnormalities in the lining of the uterus, typically due to scarring after a C-section or other uterine surgery. This might allow the placenta to grow too deeply into the uterine wall. Sometimes, however, placenta accreta occurs without a history of uterine surgery.

Definition of Placenta accreta. Placenta accreta: The abnormal adherence of the chorion of the placenta to the myometrium of the uterus. Normally there is tissue intervening between the chorionic villi and the myometrium, but in 'placenta accreta, the vascular processes of the chorion grow directly in the myometrium. Placenta accreta can progress into placenta percreta. Search MedTerms:

Sometimes the placenta attaches itself into the wall of the uterus too deeply. This can cause problems, including: 1  Placenta accreta – The placenta attaches itself too deeply and too firmly into the uterus.  Placenta increta – The placenta attaches itself even more deeply into the muscle wall of uterus.

The placenta grows in your uterus (womb) and supplies the baby with food and oxygen through the umbilical cord. Normally, the placenta grows onto the upper part of the uterus and stays there until your baby is born. During the last stage of labor, the placenta separates from the wall of the uterus, and your contractions help push it into the vagina (birth canal). This is also called the afterbirth.

Placenta percreta: A condition in which the placenta invades the uterine wall. In placenta percreta, the vascular processes of the chorion (chorionic villi), a fetal membrane that enters into the formation of the placenta, can invade the full thickness of the myometrium. This can cause an incomplete rupture of the uterus.
