What Researchers Did
Researchers conducted a literature search to identify cases of cerebral air embolism (CAE) following esophagogastroduodenoscopy (EGD) and included their experience with one patient.
What They Found
The study identified 31 cases of post-EGD cerebral air embolism, with a mean patient age of 63.7 years, and 38.7% (n=12) of patients being women. Esophageal dilatation was performed in 38.7% (n=12) of cases, and 20% (n=4) of patients with documented echocardiography had a patent foramen ovale. Hyperbaric oxygen therapy was used in 48% of cases.
