Fatal cerebral arterial gas embolism after endoscopic retrograde cholangiopancreatography

摘要

We report the case of a 50-year-old woman undergoing elective endoscopic retrograde cholangiopancreatography, who developed coma and hemiparesis secondary to severe cerebral artery gas embolism. Despite prompt diagnosis and early hyperbaric oxygen therapy (HBO ₂ ) she developed severe cerebral edema and died within 24 h.
