[Aorto-esophageal fistula caused by foreign body]

Aortoesophageal fistula is a rare but fatal cause of upper gastrointestinal bleeding. AEF develop progressively from the esophageal perforation caused by foreign body. Clinically, there is a medial chest pain, followed by hematemesis and finally terminal exsanguination. Diagnosis must be achieved during the free intervals in this triad of often rapidly succeeding signs.
