CT-guided percutaneous lung puncture with argon helium for the treatment of lung cancer can occur in several complications. The authors found that the main bronchial fibrin embolism caused by argon-helium knife treatment resulted in two cases of unilateral pulmonary atelectasis. The embolus was successfully removed by fiberoptic bronchoscopy with microwave coagulation technique.
