Question

Which artery is involved in severe bleeding from a perforated duodenal ulcer?

1) Splenic artery
2) Superior mesenteric artery
3) Inferior mesenteric artery
4) Gastroduodenal artery

Answer 1

The gastroduodenal artery, branching from the common hepatic artery that stems from the celiac trunk, is the artery involved in severe bleeding from a perforated duodenal ulcer.

Step-by-step explanation:

The artery involved in severe bleeding from a perforated duodenal ulcer is the gastroduodenal artery. This artery is a major branch of the common hepatic artery, which itself branches off from the celiac trunk (also referred to as the celiac artery), a primary artery of the abdominal aorta that supplies blood to the liver, stomach, and duodenum. The gastroduodenal artery provides blood to the proximal duodenum and pancreas, among other structures, and because it services the duodenum where ulcers commonly occur, it is often the artery implicated when there is significant bleeding due to an ulcerative condition.
