Radiographic and endoscopic studies revealed a choledocho-arterio-enteric fistula caused by erosion of the stent through t he posterior duodenal wall. The patient was treated successfully with arter ial embolization. This represents an unusual case of arterial bleeding with choledocho-arterio-enteric fistulization into the duodenum subsequent to b iliary stent erosion.
