The authors report the results of the application of electrical pulses to the region of lumbar ganglia for the treatment of patients with obliterative atherosclerosis of the blood vessels in the lower extremities. It was shown that the temporary blockade of sympathetic regulation of the lower limb arteries promotes reduction of vascular tone in the distal segments of the lower extremities, stimulates collateral blood flow, and improves microcirculation in ischemic tissues(specifically, following reconstructive surgery on the lower limb arteries).
