Here we propose a safe and efficacious technique with a specific protocole of freezing, cryoprobe placement and carbodissection.

Our results show a decrease in pain free for the first month (-40% at 1 month) which allow to reduce opioids treatment and improve the living conditions.

Pain reduction is sharper during the first two weeks (from -71.4% to 42.8%). The new increase can be explained by achieving multi metastatic patients and by disease progression itself, which makes it difficult to accurately evaluate the EVA on the treated metameric level.

The procedure time is a little longer than for alcohol and radiofrequency neurolysis (120 min including the induction of anesthesia and the patient wakes versus 45 min) but  cryoneurolysis seems to be a safe and effective procedure, that permit a monitoring in real time of the ice ball under CT guidance, and to protect the spinal cord by carbodissection.

Our results demonstrate that cryoneurolysis yields a significant diminution in pain with relief extending past the two first months.
