Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Nerve root angiography is used to confirm the feasibility (presence or absence of reproducible pain) during nerve root block. | — |
Secondary
| Measure | Time frame |
|---|---|
| The persistence of the nerve root block effect will be investigated before the procedure, immediately after the procedure, and one week later, in terms of pain NRS, physical findings that reproduce radicular pain (SLR test, Kemp test, FNST test), and the presence of adverse events (effects). | — |
