The occult stroke of CEA patients evaluated by magnetic resonance imaging 3 days after operation was as high as 17%. Cerebral blood flow autoregulation (CA) is the ability of the brain to maintain the relative stability of cerebral blood flow, and cerebral oxygen index (COx) can be used to reflect CA. A negative value of cerebral oxygen index or a value near zero indicates that CA is complete, and cerebral oxygen index close to 1 indicates that CA has lost its ability. In theory, real-time monitoring of CA function by cerebral oxygen index and individualized management strategy with this goal can potentially reduce perioperative ischemic brain injury. The purpose of this study is to explore the influence of the management strategy of monitoring CA function based on regional cerebral oxygen saturation on the postoperative neurological complications of CEA patients.",[84,85],"Carotid Endarterectomy","Cerebral Autoregulation","2025-09-02",{"date":88,"type":89},"2025-09-08","ACTUAL",{"date":91,"type":89},"2024-07-08",{"date":93,"type":78},"2026-12",{"name":5,"class":6},2]
