Abstract

|
An anterolateral cordotomy, neuroablative lesioning procedure on the spinal cord, can cause a new central pain syndrome such as postcordotomy dysesthetic pain. Though postcordotomy dysesthetic pain is a well-known central pain of iatrogenic origin, the effective treatment has not been reported. The authors describe the effectiveness of motor cortex stimulation (MCS) in a patient with chronic intractable postcordotomy dysesthetic pain. This particular type of central pain developed after an open cervical cordotomy, which was performed to relieve the chronic brachial plexus injury pain caused by a gunshot injury. MCS was performed with three-dimensional image-guided navigation system and the pain from postcordotomy dyesthetic pain dramatically reduced. The analgesic effect of the stimulation proved to be long lasting and was still present after a 24-month follow-up.
