Complications in spinal cord stimulation for treatment of angina pectoris. Differences in unipolar and multipolar percutaneous inserted electrodes.

摘要: Spinal cord stimulation (SCS) has become a well established treatment for ischaemic nociceptive pain condition such as angina pectoris. In patients not suitable candidates coronary bypass grafting or intraarterial invasive technique (i.e. PTCA and Stent) SCS is an alternative. The purpose was to record the complications: electrode fracture, infection, migration, technical equipment failure, which occurred during long-term spinal (SCS). Of 60 with severe pectoris angioplastic surgery, 22 had monopolar 38 quadripolar electrodes positioned percutaneously. were followed 1 4 month intervals in year period, all complications recorded. Infection seen 5% fracture 3% of patients. most frequent complication displacement, required operation (23%). incidence this statistically lower than (p < 0.003). All displacements within after implantation. frequency displacements, reoperations, among multipolar electrodes, due possibility noninvasive changes combinations optimize topography stimulation. Changes combination connection small migrations necessary 29% electrodes. Therefore, there no significant difference between migration epidural = 0.31). When used anginal pain, tip high, but use gave compensate avoid surgical replacement.
