Arterial Esophageal Hemorrhage: Identification of Esophageal Arteries with Computed Tomography and Successful Transcatheter Arterial Embolization in Two Cases.

Arterial esophageal hemorrhage, a relatively rare condition, necessitates prompt therapeutic intervention. The esophageal arteries, originating directly from the aorta and being extremely narrow, are often difficult to identify through angiography alone. We report two cases of arterial esophageal hemorrhage related to esophageal cancer in which the esophageal arteries were identified by contrast-enhanced computed tomography prior to angiography, enabling successful transcatheter arterial embolization. Arterial esophageal hemorrhage requires rapid treatment intervention due to its complex blood supply. Preoperative evaluation with computed tomography appears to be effective.
