Placenta accreta

The placenta can also sometimes implant abnormally into the wall of the womb. This is a rare condition known as placenta accreta. The risk of having placenta accreta is higher if there is a previous scar on the womb, such as from a previous caesarean section, as the placenta can invade into the previous scar. This is a very serious condition that can be challenging to manage and a hysterectomy (operation to remove the womb) is sometimes needed at the time of delivery.
