Bronchoscopy is a safe procedure, and complications usually are minor. They might include:
A rare, but more serious risk is a pneumothorax (noo-mo-THOR-aks), or collapsed lung. In this condition, air collects in the space around the lungs, which causes one or both lungs to collapse.
A small pneumothorax might go away on its own. However, if it interferes with breathing, your doctor may use a chest tube to remove the air.
After bronchoscopy, your doctor may suggest that you have a chest x ray to check for complications.
