Successful endovascular treatment of endoscopically unmanageable hemorrhage from a duodenal ulcer fed by a renal artery: A case report

Figure 1 Emergency endoscopy shows an A1-stage hemorrhagic ulcer on the posterior wall of the horizontal portion of the duodenum.

Figure 2 Contrast-enhanced computed tomography shows extravasation into the duodenal lumen (arrowhead) from the right renal artery (arrow).

Figure 3 Embolization of the lower branch of the right renal artery. A: 3D volume-rendered computed tomography image obtained during aortography. #Posterior superior pancreaticoduodenal artery (PSPDA; pink); *Inferior pancreaticoduodenal artery (IPDA; blue); †Lower branch of the right renal artery (lower RA; red); B: Schematic of the computed tomography image; C: Extravasation of contrast material is evident before embolization (arrow). #Endoscopic clips; D: Right renal arteriography after coil embolization shows residual extravasation (†); E: Aortography after embolization using coils and n-butyl-2-cyanoacrylate glue shows no extravasation.
