air leak
Persistent escape of air from the lung into the pleural space following thoracic surgery.
Full Definition
Air leak is a common complication following lung resection procedures, characterized by continuous or intermittent passage of air from the remaining lung tissue into the pleural space through the chest drainage system. Air leaks can result from incomplete healing of staple lines, parenchymal tears, or bronchial stump problems. Most air leaks are minor and resolve spontaneously within days, but persistent leaks may require prolonged chest tube drainage or surgical intervention. The severity and duration of air leaks significantly impact hospital length of stay and patient outcomes.
Usage
Usage note: Distinguish from bronchopleural fistula, which specifically involves bronchial communication.
