CT-Guided Percutaneous Lung Biopsy:An Analysis of Pneumothorax form Factors

Objective To study the relationship between the factors of pneumothorax on CT-guided percutaneous needle biopsy. Methods 283 patients with lung lesions were compeleted on CT-guided percutaneous needle biopsy,analysis of factor pneumothorax oc- curred and relationship between different the factors.Promoting the corresponding methods of prevention and treatment.Results 283 pa- tients with lung biopsy were successful,pneumothorax occurred in 32 cases,with the exception of 3 cases of marked pneumothorax,the oth- ers were little pneumothorax.Pneumothorax occurred is related to operated technique,the conditions of patients themselves,lesions factors, the size of puncture needle and anesthesia factor.A little pneumothorax was not treatment and a large of pneumothorax required drainage pipe.Conclusion There were correlation impact factors about pneumothorax formation on CT-guided percutaneous needle biopsy,the technique of operator is important factor of pneumothorax formed.The condition of patients themselves,lesions position,anesthesia and the size of needle are secondary factors.
