“…Both the malignancy and the EGD procedures are independent risk factors for the development of CAE. A mechanism of air entry previously proposed by Brennan et al 7 argues that during swallowing the positive pressure produced in the esophagus forces air through a fistula into the left atrium. We could not visualize a fistula during our workup and autopsy was not performed.…”
Pearls• Cerebral air emboli (CAE) are scattered, small, distally located, and characteristically of low density on CT scan. • CAE should be considered as a stroke etiology in appropriate cases.• Prevention is a key treatment strategy.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
