RESUMEN
Rupture of the major airway by blunt chest trauma is uncommon. It can potentially cause serious complications, such as tension pneumothorax or cardiovascular injuries, with an overall mortality rate reaching up to 30%. The etiology of trauma includes fall-down, traffic accidents, cycling and child abuse. Dyspnea was the most common feature, followed by hemoptysis, air leak and chest pain. It is well known that dyspnea after chest trauma is due to accumulation of secretions in the airway, mucosal and cartilaginous injuries and associated parenchymal injuries. In cases of recurrent dyspnea in children irrespective of trauma, we should consider asthma, foreign body aspiration, tracheal stenosis, bronchial tumor, mediastinal tumor, gastroesophageal reflux disease and vascular ring. In this case, we found granulation tissue repeatedly causing obstruction of the airway at the site of rupture after traffic accident. Dyspnea resolved after surgical resection of the granulation tissue. We report a case of recurrent granulation tissue showing dyspnea after bronchial rupture.
