【摘要】Aim: This study evaluates the efifcacy and safety of percutaneous computed tomography (CT)-guided neurolysis using continuous

radiofrequency

for

pain

reduction

in

oncologic

patients.Methods: Over the course of 16 months, 22 patients underwent radiofrequency neurolysis as palliative therapy for pain reduction in celiac and splachnic plexus (n = 9), thoracic (n = 1), lumbar (n = 2) and superior hypogastric plexus (n = 5), as well as stellate ganglion (n = 5). Pain levels before treatment, one week after treatment, and at the last follow-up (average follow-up 6 months) were compared by means of a Numeric Visual Scale (NVS) questionnaire and a Brief Pain Inventory (Short Form) questionnaire.Results:Median procedure time was 44 min. Median number of CT scans, performed to control correct positioning of the cannula and precise electrode placement, was 8. Pain scores of questionnaires prior to treatment (mean value 9.50 NVS units, range 8-10 NVS units) and post treatment (mean value 3.27 NVS units, range 2-6 NVS units) showed a mean decrease of 6.23 NVS units in terms of pain
