Occlusive atherosclerosis can be treated by strengthening exercise, oral medication interventional surgery. Occlusive atherosclerosis is commonly found in the middle and large arteries below the abdominal aorta, and the atherosclerosis will cause pain, limb coldness, numbness and other symptoms due to insufficient blood supply. If occlusive atherosclerosis does not cause complete occlusion of blood vessels, you can improve blood circulation in the distal limbs by walking slowly, strengthening exercise and promoting collateral circulation. Oral vasodilator drugs such as hexacosanol can also be taken to dilate blood vessels and improve ischemia. Interventional therapy, such as balloon dilatation, can also be chosen for more severe occlusions. For complete occlusion, surgical treatment such as bypass grafting or endarterectomy using artificial or autologous blood vessels is also an option. If symptoms of occlusive atherosclerosis appear, it is recommended that patients go to the hospital for a complete examination and receive regular treatment.
