Duodenal diverticular bleeding successfully treated using transcatheter arterial embolization: A case report

We present a case of an 82-year-old man with duodenal diverticular bleeding (DDB) who was successfully treated using transcatheter arterial embolization (TAE). Initially, endoscopy results indicated duodenal bleeding; however, the exact bleeding site could not be located. A follow-up computed tomography (CT) scan revealed contrast extravasation from a periampullary duodenal diverticulum. Repeated endoscopy confirmed the bleeding site. However, hemostasis failed because excessive bleeding obscured the field of vision. As his condition worsened, the patient was transferred to the radiology department for TAE. His condition gradually improved after TAE. No obvious complication was observed after discharge. This case demonstrates TAE as a feasible alternative for managing complex DDB cases.
