Abstract:
Objective: To investigate the value of CT-guided percutaneous transthoracic needle biopsy (PTNB) in diagnosis of subpleural nodules. Methods: CT-guided PTNB was performed in 147 patients with subpleural nodules. According to the angle of needle and pleura, the patients were divided into long path group (the angle of the needle and pleura ≤50°, n=83) and short path group (the angle of the needle and pleura >50°, n=64). The accuracy rate of diagnosis, success rate of single puncturing, pneumothorax and hemorrhage after operation were compared between the two groups. The number of needle adjustments, puncture time, pneumothorax and hemorrhage in patients with nodular diameter ≤10 mm, 10-20 mm and ≥20 mm were compared, respectively. Results: There was no significant difference in accuracy rate of diagnosis, success rate of single puncturing, pneumothorax nor hemorrhage after operation between the two groups (all P>0.05). The number of needle adjustments and puncture time of lesions with nodular diameter ≤10 mm and 10-20 mm in long path group were all shorter than those in short path group (all P<0.05). Conclusion: CT-guided PTNB has high accuracy for subpleural nodules. For subpleural pulmonary nodule diameter <20 mm, long path puncture is the preferred approach.
