CT-guided percutaneous selective cordotomy

In this article the technique of CT-Guided Selective Cordotomy is described. The advantages of CT guidance in percutaneous cordotomy are the measurement of spinal cord diameters at the lesion site for each individual patient, direct visualization of target electrode relations, demonstration of spinal cord displacement during the procedure and localization of the electrode system in a specific part of the spinothalamic tract. Local destruction of the spinothalamic tract leads to selective cordotomy. Since 1987, CT-Guided Cordotomy has been applied to 54 cases of intractable cancer pain. In 33 of the 54 cases, the cordotomy was selective enough to be successful with a local denervation of the area where the pain was dominant. Except for one temporary hemiparesis and one temporary ataxia, no complications or side effects were observed.
