Abstract: Objective To search,evaluate and summarize the best evidence of perioperative blood pressure management in carotid artery stenting（CAS） patients at home and abroad,in order to provide reference for clinical practice. Methods We retrieved relevant literature on perioperative blood pressure management of CAS patients in domestic and foreign databases based on the "6S" pyramid model system. The literature types included clinical decision-making,guideline,expert consensus,and systematic review. The retrieval time was from the establishment of the database to April 18,2023. Two researchers independently evaluated the quality of the literature and extracted evidence. Results A total of 7 literature were included,including 2 clinical decisions,3 guidelines and 2 expert consensus papers. Twenty-three pieces of evidence were summarized from four aspects including blood pressure management principles,preoperative blood pressure management,intraoperative blood pressure management,and postoperative blood pressure management. Conclusion This study summarizes the best evidence for perioperative blood pressure management in CAS patients. The overall quality of the evidence is high,and it is recommended that medical staff develop appropriate personalized blood pressure management plans for different groups of people to better promote patient blood pressure management.
