Abstract
Objective To explore the technique,complications and preventions of CT guided percutaneous lung biopsy in diagnosing lung neoplasms.Methods 112 cases of lung neoplasms were performed CT guided percutaneous lung biopsy with shallow breathing.All pathological results and complications were recorded and then followed clinical follow-up.Results 106 cases were diagnosed malignant tumors in the initial pathology and 6 cases non-malignant tumor.After second biopsies of the 6 cases,4 cases were confirmed malignant and 2 cases non-malignant.Of the 2 benign cases,1 was indicated malignant during follow-up.The pathological diagnosis accuracy rate was 95.54％ (107/112) after the initial biopsies.24 cases appeared pneumothorax,8 cases hemoptysis or tumor hemorrhage,1 cases pleural reaction.Conclusion CT guided lung biopsy is an ideal lung neoplasm diagnostic method with good tolerance,high diagnostic accuracy and less complications combined with shallow breathing,and it needs clear indications,well-regulated puncture technique,skilled operation with care.
