The Placenta Accreta Spectrum: Epidemiology and Risk Factors

The placenta accreta spectrum has become an important contributor to severe maternal morbidity. The true incidence is difficult to ascertain, but likely falls near 1/1000 deliveries. This number seems to have increased along with the rate of risk factors. These include placenta previa, previous cesarean section, use of assisted reproductive technologies, uterine surgeries, and advanced maternal age. With increased uterine conservation, previous retained placenta or placenta accreta have become significant risk factors. Understanding placenta accreta spectrum risk factors facilitates patient identification and safe delivery planning. Patients considering elective uterine procedures or delayed childbirth should consider the impact on peripartum morbidity.
