Placenta accreta spectrum includes the full range of abnormal placental attachment to the uterus or other structures, encompassing placenta accreta, placenta increta, placenta percreta, morbidly adherent placenta, and invasive placentation. The incidence of placenta accreta spectrum has increased in recent years, largely driven by increasing rates of cesarean delivery. Prenatal detection of placenta accreta spectrum is primarily made by ultrasound and is important to reduce maternal morbidity associated with the condition. Despite a large body of research on various placenta accreta spectrum ultrasound markers and their screening performance, inconsistencies in the literature persist. In response to the need for standardizing the definitions of placenta accreta spectrum markers and the approach to the ultrasound examination, the Society for Maternal-Fetal Medicine convened a task force with representatives from the American Institute of Ultrasound in Medicine, the American College of Obstetricians and Gynecologists, the American College of Radiology, the International Society of Ultrasound in Obstetrics and Gynecology, the Society for Radiologists in Ultrasound, the American Registry for Diagnostic Medical Sonography, and the Gottesfeld-Hohler Memorial Ultrasound Foundation. The goals of the task force were to assess placenta accreta spectrum sonographic markers on the basis of available data and expert consensus, provide a standardized approach to the prenatal ultrasound evaluation of the uterus and placenta in pregnancies at risk of placenta accreta spectrum, and identify research gaps in the field. This manuscript provides information on the Placenta Accreta Spectrum Task Force process and findings.
胎盘植入谱系包括胎盘与子宫或其他结构的一系列异常附着情况，涵盖胎盘粘连、胎盘植入、穿透性胎盘植入、凶险性前置胎盘和侵袭性胎盘植入。近年来，胎盘植入谱系的发生率有所上升，主要是由剖宫产率的增加所驱动。胎盘植入谱系的产前检测主要通过超声进行，对于降低与该病症相关的孕产妇发病率至关重要。尽管对各种胎盘植入谱系超声标志物及其筛查性能进行了大量研究，但文献中的不一致情况仍然存在。为了满足标准化胎盘植入谱系标志物定义和超声检查方法的需求，母胎医学协会召集了一个特别工作组，成员来自美国超声医学学会、美国妇产科医师学会、美国放射学会、国际妇产科超声学会、超声放射学会、美国诊断医学超声注册委员会以及戈特斯费尔德 - 霍勒纪念超声基金会。特别工作组的目标是根据现有数据和专家共识评估胎盘植入谱系超声标志物，为有胎盘植入谱系风险的妊娠提供标准化的子宫和胎盘产前超声评估方法，并确定该领域的研究空白。本手稿提供了有关胎盘植入谱系特别工作组的过程和研究结果的信息。
