Our experience with spinal cord stimulation (SCS) in peripheral vascular disease

Spinal cord stimulation (SCS) by epidural electrodes is being used more often in the treatment of patients with severe intractable ischemic pain. The promising clinical results and the objective increase in lower extremity blood flow (plethysmography, thelethermography, etc.), suggests that spinal cord stimulation may have an important role in the management of advanced arterial disease when other forms of treatment have failed. The selection criteria for implantation of SCS are very important. Our indications in patients with peripheral vascular disease are: 1. Peripheral vascular disease with severe, intractable symptoms that are untreatable by medical or surgical therapy. 2. Inflammatory or diabetic arterial disease resistant to medical treatment and/or sympathectomy. 3. Persistent and severe ischemic pain and/or ulcers in patients with patent grafts. 4. Patients for lumbar sympathectomy who have a high myocardial risk. Contraindications to implantation of SCS are claudication intermittent, large necrotic lesions (gangrene) and patients who have undergone prolonged narcotic therapy.
