Exemplary images of CT-guided percutaneous transthoracic pulmonary biopsies with and without lung emphysema.
Pulmonary nodule in otherwise normal lung parenchyma before (A) and after PTPB (B). No post-interventional complication was detected. Pictures (C) and (D) show a patient with pulmonary emphysema. After PTBP (D) CT examination revealed pneumothorax and parenchyma hematoma.
Fig 2.
Risk of pneumothorax according to the stage of pulmonary emphysema.
Multinomial logistic regression shows linear correlation of increasing emphysema percentage and a heightened risk of the incidence of pneumothorax after CT-guided PTPB.
