PURPOSE: To report our experience with technical success, complications, and long-term clinical success of radiofrequency (RF) ablation of @entity10545 . MATERIALS AND METHODS: After needle biopsy, computed tomography (CT)-guided percutaneous RF ablation was performed with general or spinal anesthesia. With an RF electrode, the lesion was heated to 90 degrees C for 6 minutes. @entity1 age and sex, lesion size and location, biopsy results, and complications were recorded. Clinical success was assessed at a minimum of 2 years after the procedure. Significance of @entity1 age and sex and lesion location and size as a predictor of biopsy result was tested by means of chi2 analysis. In addition, effects of @entity1 age and sex, lesion location and size, and biopsy results on clinical success were tested with the Fisher exact test. RESULTS: During an 11-year period, 263 @entity1 who were suspected of having @entity10545 underwent 271 ablation procedures. All procedures were technically successful. There were two anesthesia-related complications ( @entity1173 , @entity1167 ) and two minor procedure-related complications ( @entity2688 , @entity6865 ). Results at biopsy were positive in 73% (197 of 271 biopsies). Two-year follow-up data were available for 126 procedures. The other procedures had been performed more recently or the @entity1 could not be contacted. There was complete relief of symptoms after 112 of the 126 procedures (89%). For procedures performed as the initial treatment, the success rate was 91% (107 of 117 procedures). Procedures for recurrent lesions had a significantly lower success rate (six of 10 procedures [60%], P <.001). Clinical outcome was not dependent on biopsy result, @entity1 age or sex, or lesion size or location. CONCLUSION: CT-guided percutaneous RF ablation of @entity10545 is a safe and effective technique.
