Percutaneous CT-guided fine-needle aspiration of pulmonary lesions: Results and complications in 409 patients.
The purpose of this study was to report our centre's experience in the results and complications of percutaneous CT-guided lung biopsy. A retrospective review of 409 patients who underwent percutaneous CT-guided fine-needle aspiration of suspicious lung lesions for more than 5 years was carried out. Nodule sizes ranged from 0.6 to 10 cm. The calibre of the needle used was 21-23 G. Specimen adequacy and patient outcome were evaluated. Each case was reviewed for complications. Sufficient diagnostic material was obtained in 369 (90%) of the 409 fine-needle aspirations. Diagnosis was malignancy in 290 (70%) samples, four (1%) samples were suspicious for malignancy, 65 (16%) samples were negative for malignancy and definite benign findings were identified in 10 (3%) specimens. There were 25 false-negative cases and one false-positive case. Sensitivity was 92% and specificity 98%. Pneumothorax was the most common complication and occurred in 17 (4%) patients. Only one of them required thoracic drainage. Blood effusion around the lesion or along the needle track was detected on the post-biopsy CT in 8 (2%) patients. However, only one of them suffered from a mild haemoptysis. Percutaneous CT-guided biopsy is an effective and fast procedure for diagnosis of suspected pulmonary malignancy, with a low complication rate.
