Abstract

Purpose: The purpose of this study was to evaluate the diagnostic accuracy and safety of CT-guided biopsy of pulmonary lesions with fine needle aspiration (FNA) using non-coaxial technique.

 

Materials and Methods: We analyzed 442 patients who underwent CT-guided lung biopsy with FNA and non-coaxial technique to determine the diagnostic outcomes, complication rates and independent risk factors for diagnostic failure and pneumothorax.

 

Results: Diagnostic accuracy, sensitivity and specificity were 97.6%, 97.3% and 100%, respectively. The significant risk factors for the diagnostic failure were age and >35 mm lesion size. The rates of pneumothorax and chest tube placement were 19% and 2.9%, respectively. The significant risk factors for the pneumothorax were middle and lower lobe location, lesion to pleura distance >7.5 mm, and >45∘ needle trajectory angle.

 

Conclusion: CT-guided FNA of pulmonary lesions with non-coaxial technique is a safe and reliable method with a relatively low pneumothorax rate and an acceptably high diagnostic accuracy.
