Cerebral embolism is a particularly dangerous type of ischemic cerebrovascular disease. Patients present with a very abrupt onset, typically with a history of atrial fibrillation. Acute onset rapidly leads to limb paralysis, and may also cause disturbances in consciousness and seizures, among other clinical manifestations. Current guidelines for thrombolytic treatment of cerebral embolism do not address extensive cerebral embolism, as thrombolysis in extensive cerebral embolism carries a certain risk of bleeding and is not generally advocated in clinical practice. Mainly, arterial thrombectomy treatment can be administered within an eight-hour window, which can provide significant therapeutic effects for some patients. Additionally, if the cerebral embolism is considered small and the patient's consciousness is relatively intact, intravenous thrombolytic treatment can be given. The time window for intravenous thrombolysis is generally within four and a half hours, so it is crucial to get to a hospital as quickly as possible in the event of a suspected cerebral embolism.
