Case Reports
[Upper gastrointestinal hemorrhage caused by a fistula from a right anomalous subclavian artery to the esophagus].
Bleeding from an arterio-esophageal fistula is a rare and nearly lethal condition and surgical treatment is the only curative option. We report a case of bleeding from a fistula from an aberrant right subclavian artery to the esophagus. ⋯ Development of a communication between this artery and the esophagus, secondary to aneurysmatic dilatation or to prolonged nasogastric intubation, as probably occurred with this patient, is a extremely rare condition. Surgical treatment depends on the early recognition of clinical signs of the arterio-esophageal communication, before the onset of systemic complications of hypovolemic shock.
