AbstractEntry of air into the venous system leading to intracardiac air and pulmonary air embolism (PAE) has been reported in various clinical settings such as neurosurgical interventions in the sitting position and in autopsies on patients with head and neck injuries. We report the case of a 29-year-old male who developed severe pulmonary dysfunction after severe head injury in a high-velocity car accident. Chest X-ray showed bilateral diffuse patchy infiltrates. Pneumothorax, haemothorax, pulmonary aspiration, various forms of pulmonary oedema and pulmonary contusion could be excluded. Furthermore, there was an open laceration of the frontal sinus and maxillo-facial fractures. The history of spontaneous respiration in sitting position at the scene, rapid improvement of pulmonary function within 30 h, small amounts of air in the brain parenchyma, and circulatory shock despite elevated central venous pressure in the initial phase led to the diagnosis of PAE as the primary cause of pulmonary dysfunction. The diagnostic approach and basic therapeutical principles in patients with PAE are described. In conclusion, the case presented emphasizes the importance of considering PAE as a possible cause of respiratory failure in patients with severe head injury.
