Brief Summary
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.

Outcome Measures
Primary Outcomes (1)
Difference of perfusion index (%)
Difference of perfusion index (%) between ipsilateral foot and contralateral foot
before and 1 - 20 minutes after FS-guided lumbar sympathetic ganglion block
Secondary Outcomes (6)
Difference of temperature change (°C)
before and 1 - 20 minutes after FS-guided lumbar sympathetic ganglion block
Severity of pain
Time before block and 20 minutes, 1 week, 4 weeks after FS-guided lumbar sympathetic ganglion block ( The higher the score, the more severe the pain)
Proportion of patients reaching ≥ 1.5°C rise
20 minutes after FS-guided lumbar sympathetic ganglion block
Proportion of patients reaching ≥ 2.0°C rise
20 minutes after FS-guided lumbar sympathetic ganglion block
Proportion of patients reaching ≥ 100% rise of perfusion index (%)
1 - 20 minutes after FS-guided lumbar sympathetic ganglion block
- +1 more secondary outcomes
Study Arms (1)
Lumbar Sympathetic Ganglion Block (LSGB)
OTHERFS-guided LSGB at L3 level.
Interventions
A needle will be inserted at the L3 on the side experiencing pain, either right or left, under fluoroscopy guidance. Once the needle is positioned in front of the desired vertebral body, its location is confirmed using a contrast medium. If the position is well visualized in lateral and anteroposterior (AP) views, 7 mL of 0.5% ropivacaine will be injected.
Eligibility Criteria
You may qualify if:
- Lower extremity pain
- Pain for more than 3 months
- years
You may not qualify if:
- If the patient refuses to undergo the procedure
- In the presence of vascular disorders in the lower extremities
- If the patient has previously undergone lumbar sympathetic ganglion removal or neurolysis
- When there are abnormalities in blood coagulation tests
- If there is a systemic infection or infection at the injection site
- In the presence of anatomical deformities at the injection site
- If the patient has allergies to the injected medication
- In other cases where the researcher deems the patient unsuitable for participation
