Spinal cord stimulation in the treatment of neuropathic pain in chronic inflammatory demyelinating polyneuropathy.

ABSTRACT

We describe a case of a 70-year old man with sensorimotor chronic inflammatory demyelinating polyneuropathy (CIDP) with small-fibre involvement resulting in severe diffuse neuropathic pain which was refractory to immunotherapy and anti-neuropathic medication. His pain was successfully treated with implantation of a spinal cord stimulation (SCS) system comprising bilateral cervical and lumbar epidural leads. Following SCS programming, he experienced a 50% reduction in average pain severity with substantial improvement in quality of life, persisting at 18 months after surgery. SCS has been employed to treat a variety of neuropathic pain syndromes. However, this is the first report to our knowledge of SCS utilised effectively for pain in CIDP. This therapy should be considered in painful CIDP for neuropathic pain refractory to medical management, though further studies are required to evaluate its efficacy.
