[Severe digestive hemorrhage of an unusual etiology. Visible isolated and bleeding esophageal vessels].

We describe two patients with massive upper gastrointestinal bleeding. The upper gastrointestinal endoscopy revealed jet haemorrhage in the distal portion of the esophagus, from a visible vessel, without esophageal mucosal damage. In both cases arteriography was performed, and did not show vascular malformations or fistulous points. The patients were successfully treated, one with endoscopic sclerosis and balloon tamponade, and the other with endoscopic sclerosis and transcatheter embolization through left gastric artery. For the time being we do not know the true importance of these findings, but we hope that other reports help us to understand the clinical and pathologic features of this vascular lesion, and the best therapeutic approach.
