Abstract
Thirty-six cases of lumbar spinal canal stenosis with thoracic outlet syndrome, treated by satellite ganglion block, were investigated retrospectively. The average number of satellite ganglion blocks per patient was 13 (range one to 58), and the average follow-up period was five months (range one to 15). The average duration of intermittent claudication improved from 10 minutes at the first examination to 48 minutes at final follow-up, and JOA score improved from 17 points to 26. Worsened symptoms were not indicated in any cases. The average Hirabayashi’ improvement ratio was 76%, and there was no significant difference in improvement between the root type and the cauda type. How satellite ganglion block performs in lumbar spinal canal stenosis is unclear, however, the authors believe that satellite ganglion block could be a useful conservative treatment for patients with lumbar spinal canal stenosis.
