Abstract

No abstract available. Article truncated at 150 words. A 39 year-old woman was referred to our hospital for evaluation of persistent broncho-pleural fistula after severe necrotizing streptococcal pneumonia. She had undergone a segmentectomy for the necrosis resulting in the broncho-pleural fistula. Her overall medical condition and malnutrition precluded another major surgery such as a muscle flap for the persistent air leak. Endobronchial valve placement was attempted to minimize the gradient and leak across the parenchymal defect to promote healing. A sequential balloon occlusion technique was used to localize the leak to the right upper lobe, which was the site of the previous surgery. The sub-segments were measured and three endobronchial valves (Spiration®, Olympus Respiratory, USA) (1). Valves of 5 mm, 6 mm and 7 mm – were placed in the three sub-segments of the right upper lobe (Figure 1) with a flexible bronchoscope. Near elimination of the air leak was seen post procedure.
