The gastroduodenal artery (GDA) is a terminal branch of the common hepatic artery which mainly supplies the pylorus of the stomach, proximal duodenum, and the head of the pancreas. Due to its proximity to the posterior wall of the first part of the duodenum, the gastroduodenal artery is one of the most important sources of upper gastrointestinal bleeding - mostly secondary to peptic ulcer disease or erosive malignant ulcers.

Gross anatomy

The gastroduodenal artery is a terminal branch of the common hepatic artery along with the proper hepatic artery.

It passes inferiorly behind the first part of the duodenum to the left of the common bile duct where it gives off the supraduodenal artery. Inferiorly, the gastroduodenal artery relates with the head of pancreas ⁴. More inferiorly it bifurcates into 2 arteries at the upper border of the pancreas:

right gastroepiploic artery
- runs forward between the pancreas and first part of the duodenum, and passes left into the greater omentum at the head of the pancreas, and runs along the greater curvature of the stomach to anastomose with the left gastroepiploic artery (from the splenic artery)
superior pancreaticoduodenal artery
- divides into anterior and posterior branches which encircle the pancreatic head and anastomoses with similar branches of the inferior pancreaticoduodenal artery from the superior mesenteric artery
