The persistent problem of persistent air-leaks: approach to management

Purpose of review Persistent air leaks, defined as an air leak extending beyond 5 days, pose a significant challenge for cardiothoracic surgeons and pulmonologists. Although current guidelines advocate for surgical intervention as the primary treatment, many patients may not suitable candidates for immediate return to the operating room. Alternatively, conservative management, which involves watchful waiting for pleural healing, often results in prolonged hospital stays and increased morbidity. Recent findings Although current guidelines advocate for surgical intervention as the primary treatment, many patients may not suitable candidates for immediate return to the operating room. Alternatively, conservative management, which involves watchful waiting for pleural healing, often results in prolonged hospital stays and increased morbidity. For patients who are not surgical candidates, use of autologous blood patch, pleurodesis or endobronchial valves may offer a viable alternative to conservatively manage air leak. Summary This review evaluates the various noninvasive therapies that have been explored, including sealants, Heimlich valves, chemical and autologous blood patch pleurodesis, and endo and intrabronchial valves. Although these alternatives show promise, further research is needed to compare these treatments before they can be recommended in new guidelines.
