title: [A case of Saber-sheath type tracheo-bronchomalacia].
abstract: A case of Saber-sheath type tracheo-bronchomalacia complicating bronchial asthma was treated by external fixation of Marlex mesh, and good results were obtained. The patient was a 43-year-old male who had been treated for bronchial asthma for over nearly 20 years. Since 4 years ago, dyspnea and a feeling of obstruction of the larynx developed and gradually aggravated. He lost consciousness twice and was hospitalized on an emergency basis. Pulmonary function tests performed during remission of asthma attacks revealed an obstructive disorder: FEV1.0% was 30.5% and peak flow was 4.11 L/sec. Bronchoscopy and tracheo-bronchography revealed Saber-sheath type tracheo-bronchomalacia in the trachea and the right main bronchus. The severity of the obstruction was, in terms of Johnson's classification, II. for the trachea and I. for the right main bronchus. In accordance with the method reported by Hanawa and Ikeda, external fixation was applied to the trachea and the right main bronchus; that is, Marlex mesh was applied around to the trachea and the right main bronchus, and additional Lyodura was applied over the Marlex mesh. The postoperative course was satisfactory. Both FEV1.0% and the peak flow improved, and constriction of the trachea and the right main bronchus at the time of coughing was also reduced.
