The statement “carotid artery stenosis cures itself in 6 years” is unscientific and not true. It is necessary to rebuild blood flow through general treatment, drug treatment and surgery under the guidance of doctors. 1. General treatment: low-salt and low-fat diet, smoking cessation, appropriate exercise, and control of blood pressure, blood sugar, lipids and other risk factors. 2. Drug treatment: anti-platelet aggregation drugs can be applied to reduce thrombosis, such as aspirin, clopidogrel, etc. Drugs such as atorvastatin can also be used to lower lipids. 3. Surgery: Localized arterial stenosis can be improved through surgical treatment, such as carotid artery stenting, carotid artery endarterectomy and so on. When carotid artery stenosis is found, it is necessary to go to the hospital in time, clarify the cause of the disease under the guidance of the doctor, and carry out standardized treatment.
