[P-34] Correlation between clinicopathology and the depth of chorionic villi invasion of placenta accreta spectrum

The incidence of placenta accreta spectrum (PAS) has inclined with the increasing of cesarean deliveries (CD). It is divided into 3 groups based on the invasion of the chorionic villi into the myometrium (accreta, increta and percreta). The aim was to determine the correlation between clinicopathology and the depth of chorionic villi invasion of PAS....
