AbstractIn closed chest trauma, bronchial rupture is an unusual but potentially serious complication, with an associated mortality rate of 30%. Recent decades have seen an increase in incidence parallel to greater use of transport. Eighty percent of injuries are located 2.5 cm from the carina. Diagnosis is based on clinical signs, imaging and bronchoscopy. Subcutaneous emphysema and respiratory insufficiency are the most common findings. Images show the presence of pneumothorax, pneumomediastinum or both. Bronchoscopy is the diagnostic method of choice and must be performed early. Treatment consists of reestablishing anatomical continuity of the tracheobronchial tree by surgical repair if the lesion affects more than a third of the circumference and/or pneumothorax is not resolved after two chest drainages. This type of injury should be recognized and treated early, both to restore lung function and to prevent associated complications caused by delay. However, initial findings are seldom specific, requiring the physician to display a high degree of suspicion and explaining why diagnosis often comes late.
