Placenta increta is an intermediate level in the placenta accreta spectrum disorders and accounts for ~20% of such cases. The placental villi extend beyond the confines of the endometrium and invade the myometrium but do not reach the uterine serosa.
The ends of the spectrum of abnormal placental villi adherence are:
The estimated incidence is increasing (likely related to the increased practice of cesarean sections), probably ~1 in 50,000 pregnancies.
prior cesarean section
advanced maternal age
In placenta increta, chorionic villi invade well into the myometrium but not through the entire wall.
As with the less severe placenta accreta, there can be focal obliteration of the retroplacental hypoechoic zone 4.
