Figure 7 Non-variceal upper gastrointestinal bleeding due to hemobilia. A and B: Contrast-enhanced computed tomography axial scan in the arterial phase (A) and its maximum intensity projection oblique-sagittal reconstruction (B) showing a pseudoaneurysm in the lumen of the metallic biliary stent (long arrow, A), arising from the hepatic artery (short arrow, B); C: Delayed phase celiac angiography showing a pseudoaneurysm (black asterisk) into the lumen of a metallic biliary stent (white arrow); D: The pseudoaneurysm of the proper hepatic artery was reached with a 2.7 Fr microcatheter (white arrow) coaxially through a 5 Fr catheter (black arrow) positioned into the celiac trunk; E: Successful coil embolization of both the proper hepatic artery (black arrow) and the gastroduodenal artery (white arrow), in order to avoid recanalization.
