Emergency use of an endobronchial one-way valve in the management of severe air leak and massive subcutaneous emphysema.

摘要: Bronchopleural (BPF) and alveolar-pleural (APF) fistulas are frequently encountered in clinical practice with persistent air leaks that can lead to significant morbidity, prolonged hospital stay, potentially increased mortality. BPF APF commonly related pulmonary resections. Other etiologies include minimally invasive procedures (thoracentesis image-guided biopsies), spontaneous an underlying structural lung disease (e.g., emphysema) or a necrotizing process infection malignancy). Radiofrequency ablation for malignancies is effective modality rarely leak. Surgical intervention remains the standard treatment option APF. A variety of bronchoscopic approaches be considered selected nonsurgical candidates. The use one-way endobronchial valves manage severe patients. selectively block inspiratory airflow specific segmental subsegmental airway but allow expiratory flow drainage secretions from corresponding distal airways parenchyma.
