Question #193

Gastric ulceration can cause erosion through the stomach wall and into adjacent blood vessels causing haematemesis. Which of the following vessels is most likely to be involved?



Ulcers on the posterior wall of the stomach may erode through the stomach wall and into the splenic artery. This can result in large amounts of fresh blood collecting in the stomach and the patient will vomit this up (haematemesis).

Ulcers in the duodenum can erode through to the gastroduodenal artery.
