Injectate Volumes for Lumbar Lysis

      How do you determine the volume of injectates to use for a lumbar lysis? Do you often adjust these volumes because of the patient’s symptomology and/or contrast filling defects?

        Please check the update done by Gabor racz recently which I submit below.

        The volumes you used is defined in the thecniques. But the thing you must never forget is you must have a run-off of the volumes you inject from the foramens. If you do not have, you will even have problem with the low volumes, if the volumes donot run away from the filling deffect area. Then you may have major complications.
        RUN-OFF…..Dont forget…

            Dr. Akbas,

            Thank you for posting that paper, it is very informative. If you observe moderate to severe lumbar stenosis on a patent’s MRI for example, how do you determine or adjust the injectate volume? Would this also require a smaller catheter? Would you alter the actual procedure in any way?

            You perform the actual procedure. If you have run-off of the fluids you will not have any problem. But you may consider to use versa cath if you need a thinner cath. Sometimes it helps.
