Subclavian vein stenosis is generally not self-healing, but mild cases can be temporarily observed first, while severe cases can be treated with medication or surgery. Because subclavian vein stenosis cannot be cured on its own, mild cases without related symptoms can be observed temporarily without special treatment; however, if the condition is more serious and the symptoms are relatively more obvious, medication or surgery should be taken as soon as possible to alleviate the disease. Regarding subclavian vein stenosis, oral antiplatelet aggregation drugs, such as aspirin, can be used as drug treatment; for patients with high blood lipid, oral lipid-lowering drugs, such as atorvastatin, are needed. For patients with more serious conditions, stent implantation and other open-vessel treatments should be done as soon as possible. After finding out the stenosis of the clavicular vein, you should consult a doctor in time and choose the appropriate treatment under the guidance of a professional physician.
