title: [Iatrogenic gas embolism].
abstract: BACKGROUND
  Gas embolism may occur as a consequence of lung injury, decompression sickness, surgery or as accidental infusion of gas during various diagnostic procedures. Iatrogenic gas embolism is often not recognised, but can lead to severe morbidity or even death.
  
  
  METHODS
  We present a case of iatrogenic paradoxical air embolism caused by a defect in a central venous catheter. A review of the literature is given.
  
  
  RESULTS
  The patient recovered gradually, but suffered significant neurological deficits.
  
  
  CONCLUSIONS
  Gas embolism must be considered as a differential diagnosis when a patient presents with unexplained neurological symptoms. Prompt treatment using oxygen at increased pressures (hyperbaric oxygen treatment) may be lifesaving and prevent serious sequelae.
