Impact factors and treatment for complications of CT-guided percutaneous lung biopsy / 中国介入影像与治疗学

ABSTRACT

Objective: To investigate the impact factors and treatment of complications of CT-guided percutaneous lung biopsy. Methods: Complications of 253 cases of CT-guided percutaneous lung biopsy were retrospectively analyzed, and the impact factors of complications and the corresponding treatment methods were reviewed. Results: Among 253 cases, pulmonary hemorrhage was detected in 77 cases (77/253, 30.43%), including 4 cases (4/77, 5.19%) of massive hemorrhage. There were significant differences of lesions' location, size, puncture depth and number of samples between patients with and without pulmonary hemorrhage (all P<0.05). Pneumothorax occured in 55 cases (55/253, 21.74%), including 5 cases underwent closed thoracic drainage. There were significant differences of lesions' location, size and number of samples between patients with and without pneumothorax (all P<0.05). Conclusion: For CT-guided percutaneous lung biopsy, lesions' location, size, puncture depth and number of samples are the impact factors of pulmonary hemorrhage, while lesions' location, size and number of samples are impact factors of pneumothorax. The occurrence of pulmonary hemorrhage and pneumothorax can be prevented and treated.
