Brief summary (from the registry)
The patient, who is experiencing chronic pain in the lower extremities persisting for more than three months, is scheduled to undergo lumbar sympathetic ganglion block. To evaluate the technical success of the sympathetic blockade, temperature and perfusion index (PI) will be measured at one-minute intervals over a 20-minute period before and after the procedure on the treated side and the opposite side foot. Additionally, other variables related to the procedure will be assessed before the procedure, after the procedure, before discharge, and during follow-up outpatient visits or phone surveys at 1 week and 1 month after the procedure.
