postoperative air leak
Persistent escape of air from the lung surface through chest tubes after thoracic surgery. Common complication requiring monitoring and management.
Full Definition
A common complication following pulmonary resection characterized by continued air escape from the lung parenchyma through the pleural drainage system. Air leaks occur when there is incomplete sealing of the lung surface at the staple line or resection margin, allowing air from the airways to escape into the pleural space. Most air leaks are minor and resolve spontaneously within the first few postoperative days as the lung surface heals. Prolonged air leaks (typically defined as lasting more than 5-7 days) may require additional interventions such as chest tube management modifications, chemical pleurodesis, or reoperation. Air leak duration affects length of hospital stay and can impact patient recovery.
Usage
Usage note: Distinguish from bronchopleural fistula, which implies a larger, more persistent communication.
