Middle cerebral artery stenosis is serious, if active treatment is possible to cure, mainly take interventional therapy, drug therapy and so on. The middle cerebral artery is an important branch of the brain’s blood supply, and the main areas of blood supply include the cerebral cortex and basal ganglia. When the middle cerebral artery is narrowed, the function of the corresponding brain area may be damaged or lost. For example, hemiplegia, sensory abnormalities, and speech disorders. In particular, the incidence of cerebral infarction is significantly higher in patients with moderate-to-severe middle cerebral artery stenosis, so middle cerebral artery stenosis is serious. However, if these patients actively search for the cause, this kind of disease can be treated, and common treatment methods include the following: 1. Interventional therapy: If the middle cerebral artery stenosis is more than 70%, or >50% but accompanied by obvious symptoms, such as limb numbness, weakness, etc., and drug treatment is ineffective, interventional therapy can be carried out. After the intervention, long-term oral anti-platelet aggregation drugs, such as aspirin and dipyridamole, as well as statins, such as simvastatin and atorvastatin, are needed to stabilize the plaque. 2. Drug therapy: patients with middle cerebral artery stenosis should actively find the cause of stenosis and treat the cause. If there are hypertension, hyperlipidemia, diabetes mellitus underlying disease, it is necessary to actively control blood pressure, blood lipids, blood sugar, to slow down the progress of the disease and prevent the occurrence of cerebral infarction. When the middle cerebral artery stenosis is serious, attention should be paid to low-salt and low-fat diet, appropriate physical activity every day, and if there are obvious symptoms, they should go to the hospital in time.
