A CASE OF AORTOESOPHAGEAL FISTULA DUE TO AORTIC ANEURYSM THAT WAS SUCCESSFULLY TREATED BY THORACIC ENDOVASCULAR ANEURYSM REPAIR

Abstract

An 80-year-old man was admitted to the hospital after hematemesis. Endoscopic examination revealed that there was an elevated lesion with a central ulcer, similar to a submucosal tumor, in the middle thoracic esophagus. Thoracic and abdominal enhanced CT revealed that an aortic aneurysm, 35mm in size, had ruptured into the esophagus. Therefore, we made the diagnosis of aortoesophageal fistula.
In the first stage of treatment, endovascular aneurysm repair was performed and, later, a two-stage operation was successfully performed.
Although rare, aortoesophageal fistula is life-threatening, and it is difficult to make an accurate diagnosis. We report a case of rapid diagnosis of aortoesophageal fistula that was successfully treated by thoracic endovascular aneurysm repair.
