Cerebral Arterial Gas Embolism During Upper Endoscopy.

Journal Article (Journal Article)

Arterial gas embolism can be caused by direct entry of gas into systemic arteries or indirectly by venous-to-arterial shunting. Although arterial gas embolism is rare, most documented cases are iatrogenic, resulting from the entry of gas during procedures that involve direct vascular cannulation or intracavitary air insufflation. Of the 18 identified case reports of air embolism during endoscopy, 11 cases describe findings of cerebral arterial gas embolism during upper endoscopy. Only 1 of these occurred during endoscopic balloon dilation of an esophageal stricture. We report a rare case of cerebral arterial gas embolism in a 64-year-old woman, which occurred during endoscopic dilation of an esophageal stricture and was subsequently treated with hyperbaric oxygen therapy. In this case report, we explore the possible etiologies, clinical workup, and therapeutic management of cerebral artery gas embolisms. Hyperbaric oxygen therapy is the treatment of choice for cerebral arterial gas embolism, with earlier treatments resulting in better outcomes.
