Case description

As the ulcer burrows deeper into the gastroduodenal mucosa, the process causes weakening and necrosis of the arterial wall, leading to the development of a pseudoaneurysm. The weakened wall ruptures, producing hemorrhage. The flow through the vessel varies with the fourth power of the radius; thus, small increases in vessel size can mean much larger amounts of blood flow and bleeding. Visible vessels usually range from 0.3-1.8 mm.
