Cerebral infarction is a clinical syndrome caused by the acute occlusion of cerebral blood vessels, which has its own developmental and evolutionary rules. Due to the complexity of brain cells, some neurological deficits may be left behind, which we call sequelae, but overall it is still preventable and treatable. In the acute stage of cerebral infarction, the treatment of revascularization should be carried out as early as possible to improve the blood supply in the ischemic area by means of restoring blood flow to achieve the purpose of saving brain cells, and the current treatment means are various, such as intravenous thrombolysis, arterial thrombosis, arterial thrombolysis, etc. Moreover, due to the progress of technology, the endovascular treatment technology is gradually improved, and the occluded blood vessels can be reopened within a short period of time to preserve the neurological function to the greatest extent. In addition, we have achieved very good results. Cerebral infarction is actually only a disease process, not the end of the disease, and it is necessary to make full use of modern treatment technology to clarify the causes of cerebral infarction, and to carry out targeted preventive treatment for the causes in order to prevent recurrence of cerebral infarction, which is also an important aspect to achieve the purpose of cure. For patients with sequelae, rehabilitation treatment should be carried out along with drug treatment to restore the patient’s motor and self-care ability and return to family and society, so as to functionally cure cerebral infarction. In conclusion, cerebral infarction is a complex process that can be prevented and treated through active treatment and prevention, and most of the patients with cerebral infarction can reach the standard of clinical cure.
