To analyze the research content, hotspot and development trend of placenta accreta research from 2011-2021 by CiteSpace literature metrology tool, in order to provide useful reference and enlightenment for the future research direction.

Literature on placental accreta from 2011 to 2021 was retrieved from three core journals of Chinese database, namely China National Knowledge Network, Wanfang and VIP. CiteSpace software was used to analyze and draw the visual knowledge map of authors, research institutions and keyword clustering, and the research achievements in this field were sorted out.

A total of 1314 valid literatures were included.The visualization knowledge graph analysis showed that experts and scholars such as Yang Huixia, Chen Dunjin and Zhao Yangyu were the main research forces in this field. The First Hospital of Peking University, the Third Hospital of Peking University and the Second Hospital of West China of Sichuan University are the main medical institutions for the study of placenta accreta. In recent ten years, the research of placental accreta has focused on subjects such as placenta accreta, placenta previa, prenatal diagnosis, hemostasis, hysterectomy and pregnancy outcome.

Chinese scholars attach great importance to the imaging diagnosis of placental accreta disease, improvement of cesarean section surgical methods, and the prevention of severe postpartum hemorrhage. However, how to improve pregnancy management, improve maternal and infant prognosis, strengthen inter-hospital cooperation, and reduce the geographical gap are still urgent issues to be solved in the study of placenta accreta disease.
