The purpose of this article is to retrospectively evaluate the frequency and risk factors for complications after liver radiofrequency ablation (RFA).This was a retrospective study 656 patients (with 1755 tumors) who underwent 1500 CT fluoroscopy-guided RFA sessions. Of those patients, 501 had primary tumor 155 metastases. Mortality treatment-related were documented. Complications evaluated according Common Terminology Criteria Adverse Events (version 4.0). Major defined as grade 3 or higher adverse events. Factors affecting frequent with 1% more detected using multivariate analysis.Two deaths (0.1% [2/1500]) occurred. One patient died failure subsequent hemorrhage, other failure. major complication rate 2.8% (42/1500). most hemorrhage (1.1% [16/1500]). absence arterial embolization before (p < 0.01), low hemoglobin level 0.04), elevated serum creatinine 0.04) identified significant hemorrhage. minor 17.1% (257/1500). Pneumothorax (7.7% [116/1500]) complication, followed by (7.0% [105/1500]). A transthoracic approach 0.01) subphrenic location pneumothorax, use cluster needle 0.02) multiple tumors hemorrhage.CT safe procedure an acceptably treatment. in will help stratify high-risk patients.
