BACKGROUND Although conventional CT scan-guided needle biopsy is an established diagnostic method for pulmonary lesions, few large studies have been conducted on the diagnostic outcomes of CT fluoroscopy-guided lung biopsy. We have conducted a retrospective analysis to evaluate the diagnostic outcomes of 1,000 CT fluoroscopy-guided lung biopsies performed(More)
PURPOSE The authors retrospectively evaluated the safety and effectiveness of percutaneous radiofrequency ablation of lung tumors close to the heart or aorta. MATERIALS AND METHODS Forty-two tumors (mean diameter, 25 mm +/- 16; range, 5-73 mm) located less than 10 mm from the heart or aorta were treated with radiofrequency ablation in 47 sessions. Lung(More)
BACKGROUND Systemic air embolism is recognized as a potentially fatal but extremely rare complication following percutaneous transthoracic needle biopsy. However, its incidence might be underestimated by missing systemic air in patients without cardiac or cerebral symptoms. METHODS This study was based on four cases (one man and three women; age range, 54(More)
We describe two cases of intractable pneumothorax that were attributed to a bronchopleural fistula (BPF) after radiofrequency ablation of lung tumors. In both cases, radiofrequency ablation induced necrosis of the lung tissue between the pleural space and the bronchus. The bronchopleural fistula formed after sloughing of the necrotic tissue. Management of(More)
PURPOSE We retrospectively evaluated the outcomes of lung cancer patients presenting with ground-glass opacity (GGO) who received radiofrequency ablation (RFA). METHODS Sixteen patients (5 men and 11 women; mean age, 72.6 years) with 17 lung cancer lesions showing GGO (mean long axis diameter, 1.6 cm) underwent a total of 20 percutaneous computed(More)
PURPOSE To determine the effectiveness of computed tomography (CT)-guided radiofrequency (RF) ablation of malignant thoracic tumors. MATERIALS AND METHODS CT-guided RF ablations of 99 malignant thoracic tumors (3-80 mm in largest diameter; mean, 19.5 mm) were performed in 35 patients in 54 sessions. Ablation was performed with an RF generator by using a(More)
PURPOSE To retrospectively evaluate the incidence of and risk factors for pneumothorax, pleural effusion, and chest tube placement for pneumothorax after radiofrequency (RF) ablation of lung tumors. MATERIALS AND METHODS Institutional review board approval was obtained, with waiver of informed consent. This retrospective study comprised 224 ablation(More)
BACKGROUND The purpose of the study was to retrospectively evaluate the risk factors for local progression after percutaneous radiofrequency (RF) ablation of lung tumors. METHODS The study included 128 patients (77 men, 51 women; mean age, 61.3 years) with 342 tumors (25 primary and 317 metastatic lung neoplasms; mean long-axis diameter, 1.7 cm) treated(More)
PURPOSE To retrospectively evaluate the role of repeat radiofrequency (RF) ablation for local progression of lung tumors in local tumor control. MATERIALS AND METHODS From June 2001 to February 2007, the authors treated 797 lung tumors (primary lung cancer, n=66; metastatic lung neoplasm, n=731; mean tumor size, 1.7 cm) in 295 patients with RF ablation.(More)
