Aortoesophageal fistula and sudden death. A report of two cases and review of the literature

Two cases of aortoesophageal fistula are presented. The etiology, symptoms, and diagnosis of aortoesophageal fistula are reviewed. Signs and symptoms of gastrointestinal hemorrhage followed by sudden collapse hours to days later should prompt consideration of an aortoesophageal fistula. Accidental ingestion of foreign bodies, particularly by children, is a frequent etiology.
