Abstract
Gas embolism during GI endoscopy is extremely rare; only 13 cases of an endoscopy-related gas embolism are reported.1–13 This complication has been observed during various types of endoscopic procedures, including EGD, colonoscopy, and ERCP, but there is no report, to our knowledge, documenting an association with endoscopic variceal ligation (EVL) for control of active bleeding from esophageal varices. A case is presented of cerebral artery air embolism that occurred immediately after an EVL procedure and led to the death of the patient. When unexpected complications such as strokes, shock state, loss of consciousness, and sudden hypoxemia develop during an EVL procedure, especially EVL on an emergency basis for control of variceal bleeding, air embolism should be considered.
