Placenta Accreta Spectrum

Placenta accreta spectrum is a term used to describe abnormal adherence and abnormal invasion of the placenta into the uterine wall during pregnancy. The incidence of placenta accreta spectrum has steadily increased over the last 40 years and is most notably linked to rising cesarean birth rates. This condition is associated with increased maternal morbidity and mortality because of the high risk of severe hemorrhage and likely need for hysterectomy at the time of birth. Early diagnosis of abnormal placentation is preferable in order to coordinate birth planning with a interprofessional collaborative team within a high-level perinatal care center. This article describes the case of a woman diagnosed with placenta accreta spectrum and the clinical course of her pregnancy and birth.
