Vasosclerosis is mainly treated conservatively by taking antiplatelet drugs and vasodilators, and in severe cases, interventional or surgical treatment. 1.Non-surgical treatment: oral statins to lower blood lipids, stabilize arterial plaque, improve hypercoagulability, dilate blood vessels with promoting collateral circulation. Anti-platelet drugs, such as: aspirin, clopidogrel, etc. Vasodilator drugs, such as prostaglandin, sagreside, cilostazol, etc. 2.Surgical treatment: The aim is to reconstruct arterial access through surgery or endovascular luminal treatment methods. (1) Percutaneous endoluminal angioplasty: percutaneous puncture is inserted into the narrowed section of the artery, and the balloon is inflated with appropriate pressure to enlarge the diseased lumen and restore blood flow. In combination with the application of stenting, the long-term patency rate can be improved. The use of endoluminal treatment for stenosis and occlusive lesions of the iliac artery has shown positive results. Currently, it is also used to treat single or even multiple stenoses or occlusions of the femoral artery and its distal arteries, and in most cases, recent limb-saving results can be achieved. (2) Endothelial debridement: to debride the thickened intima, atheromatous plaque and secondary thrombus of the diseased artery segment, mainly for short segments of occlusive lesions of the femoral popliteal artery or patients with carotid stenosis. (3) Bypass diversion: using an autologous vein or artificial vessel to make a bridge between the proximal and distal vessels of the occluded segment.
