Abstract
Flexible fiber-optic bronchoscopy is used to determine diagnoses in pulmonary diseases. It is considered as a safe procedure, although some complications might occur, one of which is cerebral air embolism. In this case, we present the air embolism after the bronchoscopy procedure, ending in fatality. We strongly recommend that bronchoscopists should keep this complication in mind and be aware of early symptoms pertaining to the patient's state of consciousness during bronchoscopy examination. Early treatment is essential in this situation.
