SUCCESSFUL PAIN RELIEF BY MOTOR CORTEX STIMULATION FOR EXTENSIVE THALAMIC PAIN : CASE REPORT

Abstract

Thalamic pain is known as the most difficult pain syndrome to treat. This paper describes our case treated successfully by motor cortex stimulation for extensive thalamic pain. A 59-year-old man with left thalamic pain was readmitted two years after an episode of right thalamic hemorrhage. He complained of tearing pain in the left eye, burning pain in the left upper and lower extremities, and chest pain. After one week of test stimulation, permanent implantation using two electrode arrays to include the area of the lower extremity was done. Excellent pain relief has been sustained for 10 months.
