Sympathetic overactivity partly promotes the development of peripheral artery disease which mainly leads to ischemia of the lower limbs. Endovascular arterial denervation (ED) is a minimally invasive technique which could deliver Radiofrequency energy by a multi-electrode catheter to the Lower limb artery to restore Sympathetic activity. The purpose of this study is to evaluate the effects of multi-electrode radiofrequency ablation system on lower limb ischemia with PAD.


Peripheral arterial disease(PAD) show insufficient blood supply of diseased limbs, which causes intermittent claudication of lower limbs, reduced skin temperature, pain, and chronic progressive disease that still produces ulcer or necrosis. Some clinical studies have shown Sympathetic overactivity in the lower arterial ischemic disease. The multi-electrode radiofrequency ablation system can significantly reduce the excitability of sympathetic nerve, restore the normal response of sympathetic nerve, relieve the pain and discomfort of patients, effectively improve the symptoms of lower limb ischemia, and improve the quality of life of patients.
