[The aorto-esophageal fistula. A rare cause of digestive hemorrhage].

The authors report a new case of aortoesophageal fistula caused by a giant ulcer of the esophagus. Success of the surgical treatment during the bleeding period couldn't occult the seriousness of this fistula which is almost fatal. Only an early diagnosis permitting a surgical treatment in better conditions could improve the prognosis of this condition.
