The best time for thrombolysis in cerebral infarction is within 3 hours of onset, because the success rate of thrombolysis within 3 hours is higher. The current clinical time window for thrombolysis requirements is limited to within 4 and a half hours, and can be appropriately extended to within 6 hours for some patients with posterior circulation infarction. Patients with cerebral infarction who have sudden onset of neurological deficits are advised to seek immediate hospital care. Many hospitals now have stroke units, and if the patient is eligible for thrombolysis after significant examination, intravenous alteplase or urokinase can be applied. After thrombolytic treatment, a large proportion of patients have no sequelae and the disability rate of cerebral infarction is well relieved. Thrombolytic therapy for cerebral infarction is the most aggressive way to treat cerebral infarction. If the patient has passed the time window of thrombolysis, symptomatic treatment such as antiplatelet aggregation, anticoagulation and fibrin-lowering can be given to the patient in the acute phase. After the acute treatment, if the patient has sequelae, systematic rehabilitation treatment can be followed.
