Patients with cerebral infarction are generally not necessary to undergo embolization after 2-3 years. Embolization is mainly applicable to the acute phase, usually within 6 hours of onset, and can rapidly restore cerebral blood flow and improve brain tissue metabolism after embolization, which can reduce the signs and symptoms of neurological deficits, reduce sequelae, and lower the lethality. If the onset time is long before retrieving the embolus, irreversible damage has formed in the brain, and the patient’s treatment effect is poor, and it may also cause reperfusion injury. For patients with cerebral infarction, their treatment is mainly in the acute phase and ultra-early phase. Patients in the ultra-early phase can be given thrombolytic therapy and also embolization therapy, and the acute phase is generally mainly given anti-platelet aggregation and neuroprotection, as well as treatment to improve brain metabolism and improve blood circulation. If the patient’s physical signs and symptoms are severe, rehabilitation therapy is usually given.
