Treatment of subclavian artery stenosis is determined by the degree of stenosis and the presence of clinical symptoms. There are mainly drug treatment and surgical treatment. If the stenosis of the subclavian artery is mild, it can be treated by adjusting lifestyle habits, such as quitting smoking and drinking, exercising properly, and dietary adjustments, such as eating a light diet and less spicy food, and taking oral statin lipid-lowering drugs and antiplatelet drugs, such as aspirin, when high blood lipids are present. If the degree of subclavian artery stenosis is serious, or even the emergence of vertebral artery steal syndrome, i.e., dizziness, headache and other symptoms during activities, surgical treatment such as interventional balloon dilatation stenting can be carried out, and combined antiplatelet drugs should be given after the operation. If the diagnosis of subclavian artery stenosis is confirmed, timely medical treatment should be sought, and no unauthorized medication should be given to avoid delaying the condition. Pay attention to rest on weekdays, avoid excessive exertion, and improve dietary habits.
