Cerebral embolism is a relatively common ischemic cerebrovascular disease. If the area of cerebral embolism is very large and it exceeds the time window for thrombolysis, and if the patient is elderly with multiple underlying diseases, then thrombolysis is not recommended. Patients with large-area cerebral embolism have a higher probability of transitioning to cerebral hemorrhage, thus the risk of thrombolysis is very high. However, if it is within the time window for arterial thrombectomy, it is advocated to undergo arterial thrombectomy treatment. Family members can communicate more with the doctor to choose the appropriate treatment plan. If the symptoms of cerebral embolism are relatively mild, the affected area is considered small, and it is within three hours, then intravenous thrombolysis treatment could be considered. Patients undergoing intravenous thrombolysis must ensure that a cranial CT is rechecked within 24 hours to exclude any secondary bleeding.
