Computed Tomography-guided Transthoracic Core Needle Biopsy of Lung Masses: Technique, Complications and Diagnostic Yield Rate

Özet

Objectives: Computed tomography-guided core needle biopsy has an important role in the accurate histopathological diagnosisof lung masses. The present study aims to share our results of computed tomography-guided percutaneous core needle biopsy oflung masses.Methods: A total of 117 patients had computed tomography-guided percutaneous core needle biopsy for lung masses betweenJanuary 2017-September 2019 in our institution. In this study, these patients’ post-procedural complications, diagnostic-yield-ratesand radiological-histopathological correlations were evaluated retrospectively.Results: Complications occurred in 23 (20%) patients (20 (17%) of pneumothorax; 3 (3%) of hemorrhage). Chest-tube-drainagewas needed in five (4%) of all patients. No significant difference was found between complication rates and patient gender/age,tumor volume/localization or needle-path-length (p>0.05). In 77 of the 85 (91%) primary-lung-cancer-cases radiological and pathological diagnostic results were correlated.Conclusion: Computed tomography-guided core needle biopsy has a high diagnostic yield rate with acceptable complicationrates in the diagnosis of lung masses.
