Early detection and early treatment of cerebral infarction is necessary. If the cerebral infarction is acute and the onset is within 4.5 hours, thrombolysis can be done with alteplase. If the onset is within 24 hours, endovascular intervention can be considered if the thrombolytic window is exceeded or the thrombolytic effect is poor. If the patient can neither perform thrombolysis nor meet the requirement of mechanical clot retrieval, anti-platelet aggregation drugs should be used as early as possible according to the specific situation. At the same time, neurotrophic drugs such as cytarabine and olanzapine, oxygen radical scavengers such as edaravone, drugs to improve cerebral collateral circulation such as eurycomycin and butylphthalide, and drugs to improve cerebral circulation such as herbal injections of Ginkgo biloba can be added.
