Cerebral air embolism is an extremely rare complication of endoscopic procedure and often life threatening. We present two cases of cerebral infarction due to air embolization caused by an endoscopic intervention. The first case occurred during esophageal balloon dilatation for the treatment of a stricture of an anastomosis site in a 59-year-old man and the second case occurred during endoscopic papillary balloon dilatation in a 69-year-old man who had distal common bile duct stones. After the procedure, cardiopulmonary instability and altered mental status were observed in both patients, and cerebral air embolism was diagnosed in both cases. Hyperbaric oxygen therapy was started in the first case, and high FiO2 therapy was applied in the second case. Although this complication is rare, patient outcomes can be improved if physicians are aware of this potential complication, and immediately begin proper management.
