Intermittent claudication may be associated with thromboembolic vasculitis, atherosclerotic occlusive disease of the lower extremities, spinal stenosis, etc., and can be treated with medication and surgery. 1. Thromboembolic vasculitis: Thromboembolic vasculitis can lead to intermittent claudication, numbness and pain in the affected limbs, etc. It can be treated with medications such as enteric-coated aspirin, and when the condition is serious, it is feasible to use stem cell transplantation, stenting and other surgical treatments. 2. Lower extremity atherosclerotic occlusive disease: lower extremity vascular lesions caused by atherosclerosis can cause intermittent claudication of the lower extremities, lower skin temperature and other symptoms, can be given simvastatin, clopidogrel and other medications, but also endothelial debridement and other surgical treatments. 3. Spinal stenosis: when spinal stenosis compresses the spinal cord and nerves, it can lead to intermittent claudication, which can be treated with medicines such as methylcobalamin, and in severe cases, spinal decompression surgery can be performed. Intermittent claudication is recommended to go to the hospital in a timely manner, complete ultrasound and other related examinations to clarify the condition of the patient and then carry out treatment.
