Cordotomy

Cordotomy is a surgical procedure that disables selected pain-conducting tracts in the spinal cord, in order to achieve loss of pain and temperature perception. This procedure is commonly performed on patients experiencing severe pain due to cancer or other diseases for which there are currently no cure. Anterolateral cordotomy is effective for relieving unilateral, somatic pain while bilateral cordotomies may be required for visceral or bilateral pain.
Cordotomy is usually done percutaneously with fluoroscopic guidance while the patient is under local anesthesia. Open cordotomy, which requires a laminectomy, is often risky for patients with poor medical conditions, but may be required if percutaneous cordotomy is not feasible or an attempt has failed.
