Lusorian artery lesion as rare cause of severe upper gastrointestinal tract bleeding

Abstract

A patient in an intensive care unit experienced severe esophageal bleeding caused by erosion of a lusorian artery. The lusorian artery is a rare variant of the right subclavian artery. It originates in the descending aortic arch and crosses behind the esophagus to the right, sometimes generating esophageal compression. The patient's condition required respirator therapy and placement of a duodenal tube. At the point of crossing over of the lusorian artery and the esophagus, the duodenal tube caused esophageal necrosis, leading to erosion of the lusorian artery. This resulted in extensive esophageal bleeding, which at last required surgical intervention. To attain proper treatment and to avoid unnecessary diagnostic and therapeutic approaches, a lusorian artery lesion has to be included in the differential diagnosis of upper gastrointestinal bleeding.
