A 32-year-old man had been suffering from dyspnea on exertion and stridor, which were due to stenosis of the left main bronchus as a complication of bronchial tuberculosis. A three-connection stent, 1.2 cm in diameter and 4.5 cm in length was placed at the site of the bronchial stenosis. Dyspnea disappeared 2 days after the procedure, and the pulmonary function 3 weeks later showed considerable improvements in %FVC, FEV1 and MMF.
