“…The rate of pneumothorax in this study (38%) is within the reported range for cryoablation (12%-62%) (6,8,13,(20)(21)(22) and equivalent to that reported in a metaanalysis for RF ablation (23). The percentage of cases in this study in which chest tube placement was required (15%) is higher than average for percutaneous cryoablation (8,22), is 5% above the average for RF ablation (23,24), but is equivalent to the reported rate for microwave ablation (25).…”
