Abstract

[Objective] To investigate the application value of CT-guided percutaneous transthoracic needle biopsy of small pulmonary nodules. [Methods] 39 cases proved by cytopathologic and histopathologic examination or clinic follow-up information were collected. The nodule diameters were 1.0~3.0 cm (mean 2.1 cm). Each case was reviewed for complications after the operations in 7 days. The majority of the people were observed in 3~28 months (mean 13 months). [Results] Of 39 cases studied, 21 cases were proved to be malignant and 18 cases were benign lesion. The malignant diagnostic accuracy was 81% (17/21) and the benign 73% (14/18). 6 cases occurred pneumothorax and emptysis were seen in 2 cases. [Conclusion] CT-guided percutaneous transthoracic needle biopsy is very important to confirm the character of the small pulmonary nodules.
