According to the compromised uterine layers, they will be classified as placenta accreta (contacts myometrium), increta (penetrates myometrium) and percreta (compromises the entire myometrium and / or possibly adjacent organs), being previous caesarean section and placenta previous its major risk factor. In this review, we included definitions, diagnosis, and the new topics in non-conservative surgical management developed by the International Federation of Obstetrics and Gynecolgy published in 2018, and developing a discussion of the topic. © 2018 Sociedad Chilena de Obstetricia y Ginecologia.
