Right Gastroepiploic Vein, Anterior View

Description

Arising along the greater curvature of the stomach, the right gastroepiploic (right gastro-omental) vein courses from right to left adjacent to the inferior gastric margin, paralleling the right gastroepiploic artery within the layers of the greater omentum. From an anterior perspective, the vessel lies inferior to the gastric body and antrum, with the pyloric region and proximal duodenum positioned to its right, and the abdominal esophagus entering the gastric cardia superiorly. Tributary venules from the anterior gastric wall converge into the main channel as it approaches its proximal drainage. This is the venous line you follow along the greater curvature. Clinically, the right gastroepiploic vein is a dependable landmark during antrectomy, pyloroplasty, and gastrojejunostomy, where the gastrocolic ligament is opened to enter the lesser sac and the greater curvature is mobilized. Injury or inadequate ligation here contributes to troublesome omental bleeding, and the vein’s proximity to the gastroduodenal region makes it relevant when dissecting near the pylorus in peptic ulcer disease or gastric outlet obstruction. Its venous drainage into the superior mesenteric vein, and then the portal system, also anchors teaching on portosystemic physiology and how gastric and omental veins behave in portal hypertension. Use this illustration for gross anatomy modules on foregut vasculature, surgical teaching files on greater-curvature approaches, and publisher figures addressing gastric resection planes, lymphadenectomy along the gastro-omental arcade, or portal venous tributaries. It also fits well in endoscopy and radiology correlations when orienting learners to anterior gastric landmarks before discussing CT angiography or operative clips.
