After conception, the fertilized egg meanders to the end of your fallopian tube and enters your uterus, searching for the uterine wall. If it successfully implants itself there, the placenta will begin to form at that very spot about a week later. By the end of the first trimester, the placenta is fully grown and weighs about 1 1/4 pounds.
The difference between placenta accreta, increta or percreta is determined by the severity of the attachment of the placenta to the uterine wall. Placenta Accreta occurs when the placenta attaches too deep in the uterine wall but it does not penetrate the uterine muscle. Placenta accreta is the most common accounting for approximately 75% of all cases. Placenta Increta occurs when the placenta attaches even deeper into the uterine wall and does penetrate into the uterine muscle. Placenta increta accounts for approximately 15% of all cases. Placenta Percreta occurs when the placenta penetrates through the entire uterine wall and attaches to another organ such as the bladder.
