CASE PRESENTATION: In May 2015, a 19-year-old non-smoker patient was referred to a tertiary hospital with dyspnea on exertion, wheeze, non-productive cough and dizziness, over the past 12 months. She was treated as asthma but symptoms worsened despite of good adherence to treatmente requiring systemic corticosteroid therapy, emergency room visits, and hospital admissions. Clinical examination: stridor, diffuse wheezing, oxygen desaturation to minimum efforts. Denied respiratory symptoms in childhood or previous pulmonary disease. Reported untreated chronic rhinosinusitis. History of intubation followed by tracheostomy during 33 days, in May 2014, after a car accident, that caused ribs and vertebra fractures, kidney and spleen drilling, undergoing splenectomy. Image exams show reduction of tracheal diameter, and bronchoscopy shows narrowing of about 90% of the trachea. She underwent rigid bronchoscopic tracheal dilations with rigid sheaths 6.5; 7.5; 8.5. From the first dilation session, endoscopic evaluation revealed gradual improvement of tracheal stenosis. Patient reports improvement of symptoms and lung functional tests are normal in follow up visit.
