Placenta accreta is defined as abnormal trophoblast invasion of part or the entire placenta into the myometrium of the uterine wall. Placenta accreta spectrum (PAS), formerly known as morbidly adherent placenta, refers to the range of pathologic adherence of the placenta, including placenta increta, percreta, and accreta. An important risk factor of placenta accreta is placenta previa in the presence of a uterine scar. Placenta previa is an independent risk factor for placenta accreta.Additional reported risk factors for placenta accreta include increased maternal age and multiparity, other prior uterine surgery, prior uterine curettage,uterine irradiation, Asherman syndrome, uterine leiomyomata, uterine anomalies, hypertensive disorders of pregnancy and smoking. (1,2) Maternal morbidity and mortality can occur because of severe and sometimes life-threatening hemorrhage, which often requires blood transfusion also and rates of maternal death are increased for women with PAS. Additionally, patients with PAS are more likely to require hysterectomy at the time of delivery or during the postpartum period and have longer hospital stays states.(3) According to FIGO Classification of PAS Disorders 2019 There are three grades. Grade 1: abnormally adherent placenta (placenta adherent or accreta) - attached directly to the surface of the middle layer of the uterine wall (myometrium) without invading it, Grade 2: abnormally invasive placenta (increta) - invasion into the myometrium and Grade 3: abnormally invasive placenta (percreta) invasion may reach surrounding pelvic tissues, vessels and organs.(4) Nowadays, fertility sparing and conservative methods can be applied. These methods include placenta left in situ, cervical inversion technique , triple-P procedure, cervico-isthmic compression suture and anterior wall uterine resection
