Background:
To investigate the diagnostic significance of percutaneous lung puncture for solid pulmonary nodules (diameter ≤15 mm).
Methods:
This study retrospectively included 20 patients with solid pulmonary nodules who underwent percutaneous puncture from January 2014 to December 2018, including 11 males and 9 females. The diameter of the lesion is between 0.5 cm-1.5 cm, excluding severe organ dysfunction, and patients with coagulopathy.
Results:
All 20 patients were successfully selected, and 19 patients were diagnosed with pathological diagnosis. Among them, 11 patients found malignant tumor cells, which were clearly malignant tumors of the lungs, 5 cases of chronic inflammation of the lungs, 2 cases of fibrous tissue hyperplasia, and 1 case of lung cartilage tissue, no tumor cells were found in 1 case. One patient with a small amount of pneumothorax after puncture and one patient with a small amount of pleural effusion on the puncturesite.
Conclusions:
Percutaneous lung puncture has a high effectiveness and safety for the diagnosis of solid pulmonary nodules.
