    Rationale And ObjectivesThe aim of this study was to determine the effect of cryoablation on pain levels in patients with histories of post-thoracotomy pain syndrome.Materials And MethodsEighteen patients were included in this retrospective review. Preprocedural and immediate postprocedural pain scores were recorded, as well as several months after the procedures.ResultsThe average preprocedural pain score was 7.5 +/- 2.0, which decreased to 1.2 +/- 1.9 immediately after the procedure. After a mean follow-up period of 51 days, the average pain score was 4.1 +/- 1.7. The difference between preprocedural and postprocedural pain scores was statistically significant by Wilcoxon's rank sum test.ConclusionCryoneurolysis of the intercostal nerves statistically significantly decreased pain scores in patients with post-thoracotomy pain syndrome.Copyright 2010 AUR.
