Placenta Accreta

The placenta is normally attached to the uterine wall, and the condition when the placenta attaches itself too deeply into the wall of the uterus is regarded as placenta accreta, placenta increta, or placenta percreta depending on the severity and the deepness of the placenta attachment. Approximately 1 in 2,500 pregnancies are found to experience placenta accreta, increta or percreta.

The difference between accreta, increta or percreta

The severity of the attachment of the placenta to the uterine wall decides whether it is placenta accreta, increta or percreta. When the placenta attaches too deep in the uterine wall without penetrating the uterine muscle it may lead to Placenta Accreta. According to the studies, over the 75% of the pregnant women are affected by placenta accreta. Placenta Increta occurs when the placenta attaches even deeper into the uterine wall but do not penetrate into the uterine muscle. Approximately 15% of the cases are subjected to placenta increta. Placenta Percreta occurs when the placenta penetrates through the entire uterine wall and get attached to another organ such as the bladder. Placenta percreta is the least common one among the three conditions which is approximately 5% of all cases.


Causes of placenta accreta

Unfortunately, the specific cause of placenta accreta is unknown, but it can be related to placenta previa and previous cesarean deliveries. Studies reveal that placenta accreta is present in 5% to 10% of women with placenta previa.

A cesarean delivery increases the possibility of a future placenta accreta, and the possibility of more cesareans in the future. Multiple cesareans were present in about 60% of placenta accreta cases.
