| Summary: | Bronchopleural fistula (BPF) is a communication between the pleural space and the bronchial tree. Herein, we report a patient with persistent air leak after necrotizing pneumonia, where tract of BPF was not apparent in computed tomography (CT). Despite control of infection, watchful observation, repetitive procedures, and surgery, air leak was not resolved. This led to consideration of the endobronchial valve (EBV) placement. After identifying the bronchial segment leading to the fistula with indigo carmine, precise occlusion of the lingular division of the left upper lobe (LUL) was performed using an EBV. Subsequently, the air leak was resolved. During 6 months of follow-up, neither recurrence of BPF nor any procedure-related complications were noted. We concluded that precise EBV placement by identifying bronchial segment leading to the BPF, could be an effective treatment for persistent air leak.
