Placenta accreta spectrum (PAS) is pathologic adherence and excessive penetration of part or all of the placenta into the myometrium, including accreta, increta, or percreta [The management of PAS include early prenatal screening and referral to tertiary centers with experienced multidisciplinary teams [According to International Federation of Gynecology and Obstetrics (FIGO) guidelines, the principal surgical strategy to prevent excessive bleeding related to PAS is to leave the placenta in situ and perform a primary peripartum hysterectomy at delivery [After China raised a family’s limit on children to two at the end of 2015, there was an increase in second pregnancies, and the incidence of PAS and associated maternal deaths dramatically increased across the country [The purpose of this study was to compare the UAL + CST approach and other existing approaches by measuring blood loss using direct measurement and gravimetric methods, blood transfusion, and other adverse effects to determine the feasibility of UAL + CST approach. The secondary purpose was to evaluate the impact of MRI in PAS management, as it was commonly implemented in obstetric practice in this center.
