Re-expansion pulmonary oedema and circulatory shock in a 20-year-old man.

Re-expansion pulmonary oedema is a well-recognized rare complication of the treatment of spontaneous pneumothorax. It has been associated with death in 20% of cases. A fit 20-year-old man who had returned from holiday 2 days previously presented with a large left-sided pneumothorax of 10 days' duration. He had exhibited symptoms of chest pain and shortness of breath during the return flight. He showed no signs of respiratory distress at presentation to the Accident and Emergency Department, but after treatment with a chest tube in the ensuing 90 min developed severe unilateral re-expansion pulmonary oedema and circulatory collapse. Factors in the aetiology of the condition and prevention are considered.
