Risk factors for Placenta Accreta include all of the following, except:
In placenta accreta, there is a failure of normal decidua to form which causes the placenta to be directly anchored to the myometrium either paially or completely without any intervening decidua. Placenta prae in the present pregnancy is a risk factor for placenta accreta but previous placenta prae is not a risk factor. Ref: Manual of Pathology of the Human Placenta By Rebecca N.
