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 right and left gastroepiploic arteries (also known as gastroomental) provide the sole blood supply to the greater omentum. Both are branches of the celiac trunk . The right gastroepiploic artery is a branch of the gastroduodenal artery , which is a branch of the common hepatic artery , which is a branch of the celiac trunk.
The gastroduodenal artery can be the source of a significant gastrointestinal bleed, which may arise as a complication of peptic ulcer disease.Because of its close relationship to the posteromedial wall of the second part of the duodenum, deeply penetrating ulcers or tumours of the duodenum may cause torrential bleeding from the gastroduodenal ‘artery of haemorrhage'. [1]
The greater curvature, which begins at the cardiac notch, and arches backwards, passing inferiorly to the left, [1] is four or five times longer than the lesser curvature, [2] which attaches to the hepatogastric ligament and is supplied by the left gastric artery and right gastric branch of the hepatic artery. [1]
The right gastroepiploic vein (right gastroomental vein) is a blood vessel that drains blood from the greater curvature and left part of the body of the stomach into the superior mesenteric vein. It runs from left to right along the greater curvature of the stomach between the two layers of the greater omentum , along with the right ...
The greater curvature is supplied by the right gastroepiploic artery inferiorly and the left gastroepiploic artery superiorly. The fundus of the stomach, and also the upper portion of the greater curvature, is supplied by 5-7 short gastric arteries, which arise from the splenic artery. [17]
The left gastroepiploic artery (or left gastro-omental artery), the largest branch of the splenic artery, runs from left to right about a finger's breadth or more from the greater curvature of the stomach, between the layers of the greater omentum, and anastomoses with the right gastroepiploic (a branch of the right gastro-duodenal artery originating from the hepatic branch of the coeliac trunk).
The right gastric artery usually arises from the proper hepatic artery. It descends to the pyloric end of the stomach before passing from right to left along its lesser curvature, supplying it with branches, and finally anastomosing with the left gastric artery. [1] [verification needed]
