Pulmonary herpes resection is not dangerous. Wedge resection of pulmonary blisters is the smallest surgery in thoracic surgery, which is characterized by thoracoscopic wedge resection of pulmonary blisters with less damaged tissues. If there is a re-rupture of the pulmonary blister, only a localized pneumothorax will be formed and no large area of the lung will be compressed, and the recurrence of pneumothorax will no longer occur easily. Therefore, wedge resection should be performed for pulmonary blisters.
