Cerebral blood supply insufficiency is a relatively common type of clinical disease, which is due to various causes of craniocerebral blood flow disorders, resulting in different neurological deficits symptoms. According to different causes, the treatment measures are different. First, the most common is cerebral infarction, generally due to cerebral arterial stenosis caused by craniocerebral blood flow obstruction, can be given antiplatelet drugs (aspirin, clopidogrel, ozagrel, indomethacin, tirofiban, etc.), statin drugs (riscovastatin, atorvastatin, simvastatin, etc.), to improve the circulation of the drug (thromboembolism, hemosiderophores, ginkgo biloba preparation, etc.), and there are also other drugs edaravone, cytarabine, choline and so on. choline, and other drugs. When combined with severe intracranial and extracranial arterial stenosis, endovascular stenting can be given. Second, other internal diseases, when combined with severe anemia, need to give active blood replenishment treatment; hypotension to give pressure-raising treatment; arrhythmia patients can be given to correct the arrhythmia drugs; heart failure patients to give cardiac, diuretic and other symptomatic treatment; for systemic malnutrition and systemic consumptive diseases, can be given to the symptomatic supportive treatment.
