Whether intermittent claudication can be completely treated with medication should be judged according to the cause of the disease, some diseases can be treated, such as vascular diseases, and some diseases can not be completely treated, such as lumbar spinal stenosis. 1. Diseases of vascular origin: the common ones are thromboembolic vasculitis, atherosclerosis, primary wandering thrombosed superficial phlebitis, periarteritis nodosa, diabetic foot disease and so on. Mild symptoms can be treated with medication to completely improve symptoms, such as vasodilators (nicardipine), anticoagulants (prostaglandin E1), and antiplatelet agents (clopidogrel) for thromboembolic vasculitis. If the symptoms are severe, surgery is usually needed for complete treatment. 2. Neurogenic diseases: common diseases include lumbar spinal stenosis, lumbar disc herniation, lumbar slipped disc and other diseases, drug treatment can only improve the symptoms, if this kind of disease caused by the patient’s claudication, usually due to the nerve suffered from compression or damage caused by most patients through surgical treatment in order to fundamentally lift the disease. In addition to the above diseases that can cause intermittent claudication, diseases of spinal cord origin (such as spinal vascular lesions, spinal arteriovenous fistula, etc.) can also cause the above symptoms, depending on the specific nature of the disease, the severity of the disease to make a comprehensive judgment. Although drugs have the effect of relieving the above symptoms to a certain extent, but a single drug treatment generally can not be completely treated, it is recommended that patients under the guidance of a doctor to use drugs for regular treatment.
