We report a case of an iatrogenic tracheal rupture following an endotracheal intubation. The 78-year-old patient was admitted to the intensive care unit because of an acute respiratory failure related to a severe nosocomial pneumonia occurring 21 days after an abdominal aorta surgery. His main antecedent was a cigarette smoke-induced chronic obstructive pulmonary disease. Immediately after being intubated, a traumatic tracheobronchial rupture was suspected because of the sudden appearance of cervicothoracic subcutaneous emphysema. A thoracic computed tomography with multiplanar reformations confirmed the diagnosis and the evolution was unfortunately rapidly unfavourable. Risk factors, clinical and radiological aspects, and management of this rare but serious complication of endotracheal intubation will be discussed.
