Prediction of the degree of abnormal invasive placentation by obstetric history.

Background: Diagnosis of placenta accrete spectrum (PAS) disorders is of utmost importance and mostly relies on high index of suspicion and sonographic criteria. The degree of abnormal invasive placentation is strongly associated with patients' outcomes. We aimed to determine the association between prior obstetric characteristics and the degree of PAS.

Placenta accrete spectrum (PAS) is a complicated obstetrical condition arising from abnormal implantation of the placenta into the myometrium. The placenta might partially or completely adhere to the myometrium and in rare cases invade adjacent organs (placenta percreta). The abnormal placentation might cause life-threatening hemorrhages during pregnancy and birth, increasing maternal and neonatal mortality and morbidity.
