Aortoesophageal fistula due to esophageal ulcer.

Aortoesophageal fistula is a rare but fatal disease. Many such fistulas are caused by an aortic aneurysm, a previous operation, or esophageal disease. We report a case of aortoesophageal fistula due to an esophageal ulcer. A 66-year-old man suffered massive hematemesis; he was diagnosed as having an aortoesophageal fistula due to an esophageal ulcer after examination by upper endoscopy, computed tomography, and angiography. He had no aortic aneurysm, nor was there a history of a previous operation. An emergency operation was performed, but we could only accomplish closure because clamping of the aorta was impossible, and the source of the bleeding could not be established. He died 4 days later after sudden hemorrhage. Surgical outcome depends on early surgical intervention before massive hemorrhage occurs.
