Clinical application of CT-guided percutaneous lung biopsy

Objective To explore the diagnostic value of CT-guided percutaneous lung biopsy for pulmonary soid lesions.Methods CT-guided percutaneous lung biopsy was performed in 197 cases of pulmonary soid lesions.The lesions were 2~10 cm(mean:4.2 cm) in diameter,and the distance to the pleura was 0~8 cm(mean:3.4 cm).Results Confirmative diagnostic rate was 94.9%(187/197).The biopsy could not indicate the accurate diagnosis in 10 cases,6 of which were identified as having squamous cell carcimoma by operation,and 4 of which was followed for 2 year with no change.Post operative complications included 28 cases of pneum othorax,2 cases of hem othorax,and 6 cases of emptysis.Conclusions CT-guided percutaneous lung biopsy is safe,which offers a high diagnostic rate especially for lesions near the pleura.
