상지 복합부위통증증후군 I형 환자에서 시행한 8극 척수자극술 -증례보고-

Abstract

The most important factors for successful stimulation of the spinal cord are strict patient selection and proper lead position. To ensure proper lead position, paresthesia produced by the stimulator should cover all of the areas in which pain is occurring. Until recently, only the quadripolar electrode lead has been used in for spinal cord stimulation in Korea, however, the 8 electrode lead was recently introduced to offer greater programming options and enhance the precision with which paresthesias is delivered to the desired sites. In addition, because the 8-electrode lead has a longer electrode span, it provides greater dermatomal coverage of up to 2 vertebral segments. Furthermore, the 8-electrode lead allows electronic repositioning of the stimulation to accommodate changing pain patterns, thereby reducing the need for lead revisions due to lead migration. Here, we present a case in which complex regional pain syndrome type I was successfully managed using an 8-electrode lead to induce spinal cord stimulation.
