The Harm Of Lung Biopsy Needle

Lung biopsy puncture usually refers to percutaneous CT-guided puncture, and the main complications are pneumothorax and bleeding, specifically as follows:
1, pneumothorax: usually a small amount of pneumothorax, a large number of pneumothorax less. If the amount of pneumothorax is large, after catheterization or direct puncture, it will not cause serious danger in most cases and is usually under control.
2, bleeding: divided into hemoptysis and pleural cavity or local tissue bleeding. Some patients will have several days of hemoptysis after lung biopsy and puncture, and may have blood in the sputum for several days. In short, the blood in the sputum may disappear within 24 hours, in long, it may take 1 week to disappear. Sputum with a small amount of blood, usually not serious. But the amount of hemoptysis, may need to use the treatment of hemoptysis drugs for treatment. In addition, although hemorrhage in the pleural cavity is rare, the possibility of hemorrhage or pneumothorax should be fully evaluated and the occurrence of hemorrhage or pneumothorax should be reduced as much as possible. The doctor performing lung biopsy and puncture will also give full consideration to this situation.
Pneumothorax is usually more likely if there is local emphysema, or if there is emphysema throughout the lung, or if the lesion is deep and passes through more normal lung tissue. If the lesion is close to the large blood vessels, there are thicker blood vessels around, the possibility of bleeding is also relatively large. Therefore, an enhanced CT scan is usually performed before the puncture, especially if it is close to a large blood vessel, to assess the relationship between the tumor and the blood vessel and minimize complications.
