PURPOSE: To assess risk factors and the extent of pulmonary hemorrhage complicating radiofrequency ablation (RFA) of pulmonary neoplasms.
MATERIALS AND METHODS: This retrospective study involved 248 ablation sessions for lung tumors (20 primary lesions and 228 metastatic lesions) in 164 patients (mean age 59.7 years, SD: 10.2). Both unipolar and bipolar radiofrequency systems were used under CT fluoroscopic guidance. Extent and underlying factors associated with development of pulmonary hemorrhage were analyzed.
RESULTS: Incidence of intra-parenchymal pulmonary hemorrhage, pleural effusion, and hemoptysis were 17.7% (44/248 sessions), 4% (8/248 sessions), and 16.1% (40/248 sessions), respectively. Death because of massive bleeding occurred in one session (0.4%). Significant risk factors associated with intra-parenchymal hemorrhage included: lesions of <1.5 cm diameter (P=0.007); basal and middle lung zone lesions (P=0.026); increased needle track distance traversing the lung parenchyma>2.5 cm (P=0.0017); traversing pulmonary vessels in the track of ablation (P<0.001); and the use of multi-tined electrodes (P=0.004). Concomitant incidence of pulmonary hemorrhage and pneumothorax was 29.2% (14/48 sessions).
CONCLUSION: While typically safe, RFA of pulmonary neoplasms can result in pulmonary hemorrhage ranging from mild to life-threatening. Management of this complication is mainly preventive through adequate patient selection for ablation therapy and exclusion of technically avoidable risk factors.
