What should be suspected if an air leak persists for several days after chest tube placement?

• A. Bronchopleural fistula or persistent leak; requires reassessment and possible surgical consult
• B. Normal healing
• C. No air leak indicates problem
• D. The tube is clogged

Answer: (A)

Persistent air leak after chest tube placement means there is ongoing communication between the airway and the pleural space, most commonly a bronchopleural fistula. This is not expected as the lung re-expands and seals the pleural space; when the leak lasts for several days, it signals a solution that isn’t occurring naturally. Because of this, reassessment is needed to confirm the tube is functioning and the lung is re-expanding normally, and a thoracic surgery consult is often appropriate to plan definitive management. In the meantime, continue appropriate chest-tube management (ensuring the tube is patent, monitoring suction if used, and watching for signs of infection or empyema) and consider bronchoscopic evaluation to localize the leak or discuss endoscopic or surgical options if a fistula is confirmed. A normal healing process would not involve a persistent leak, and a clogged tube would present differently, so the persistent leak points to a longer-standing communication rather than a simple technical problem.
