Application value of CT-guided percutaneous lung biopsy in lung disease / 实用放射学杂志

ABSTRACT

Objective To investigate the efficiency and application value of CT-guided percutaneous puncture biopsy in the diagnosis of lung disease.Methods The clinical and imaging data of 60 patients with CT-guided percutaneous lung biopsy were analyzed retrospectively.Results Among all the 60 patients, 57 had finally to be proved by pathological diagnosis, including 47 primary lung cancer (21 squamous cell carcinoma, 18 adenocarcinoma, 3 small cell lung cancer and 5 bronchioloalveolar carcinoma), 7 metastatic lung cancer and 3 tuberculosis.In addition, 3 cases were chronic inflammation and did not make a definite diagnosis, in which 2 were proved to be caseous pneumonia and 1 was proved to be fungus infection by postoperative pathology.The successful rate of punctures,the diagnostic accuracy and the total complications rate of lung puncture biopsy in 60 cases was 100%, 95.0% and 21.7% [11.7% pneumothorax (7/60), 8.3% hemoptysis (5/60) and 1.7% needle bleeding(1/60)].Conclusion CT-guided percutaneous puncture biopsy is a safe, accurate and significant clinical method in the diagnosis and differential diagnosis of lung lesions.
