The gastroduodenal artery most commonly originates from the common hepatic artery, which is a branch of the celiac trunk. Occasionally, it may arise from the proper hepatic artery or from the right or left hepatic arteries, but these are less common anatomical variations.
The reason for that is explained by their location. The peritoneal or abdominal cavity is located anterior to the duodenum. Therefore, if the ulcer grows deep enough, it will perforate, whereas if a posterior ulcer grows deep enough, it will penetrate the gastroduodenal artery and bleed. [citation needed]
hepatic artery proper: supplies the gallbladder via the cystic artery and the liver via the left and right hepatic arteries gastroduodenal artery: branches into the right gastroepiploic artery and superior pancreaticoduodenal artery: right gastric artery: branches to supply the lesser curvature of the stomach inferiorly
It is a branch of the gastroduodenal artery, which most commonly arises from the common hepatic artery of the celiac trunk, although there are numerous variations of the origin of the gastroduodenal artery. [1] The pancreaticoduodenal artery divides into two branches as it descends, an anterior and posterior branch.
A branch of the common hepatic artery – the gastroduodenal artery gives off the small supraduodenal artery to the duodenal bulb. Then the right gastric artery comes off and runs to the left along the lesser curvature of the stomach to meet the left gastric artery, which is a branch of the celiac trunk. It subsequently bifurcates into the ...
The right gastroepiploic artery (or right gastro-omental artery) is one of the two terminal branches of the gastroduodenal artery.It runs from right to left along the greater curvature of the stomach, between the layers of the greater omentum, anastomosing with the left gastroepiploic artery, a branch of the splenic artery.
The celiac artery is the first major branch of the descending abdominal aorta, branching at a 90° angle. [1] [2] This occurs just below the crus of the diaphragm. [2] This is around the first lumbar vertebra. [3] There are three main divisions of the celiac artery, and each in turn has its own named branches:
Visceral nodes of the abdominal cavity. The hepatic lymph nodes consist of the following groups: (a) hepatic, on the stem of the hepatic artery, and extending upward along the common bile duct, between the two layers of the lesser omentum, as far as the porta hepatis; the cystic gland, a member of this group, is placed near the neck of the gall-bladder;
