Arteries of stomach  Left and right gastric arteries  Arise from celiac trunk and proper hepatic artery, respectively.  These two vessels run in lesser omentum along lesser curvature , and anastomose end-to-end

Arteries of stomach Rightand leftgastro-omental arteries Arise from the gastroduodenal and splenic artery. These two vessels pass into the greater omentum,run parallel to the greater curvature,and anastomose end-to-end

Arteries of stomach  Right and left gastro-omental arteries  Arise from the gastroduodenal and splenic artery.  These two vessels pass into the greater omentum, run parallel to the greater curvature, and anastomose end-to-end

Arteries of stomach Short gastric arteries Branches of splenic artery through the gastrosplenic ligament Supply the fundus of stomach. Posterior gastric artery (72%) Arise from the splenic artery through the gastrophrenic ligament and supply the posterior wall of fundus of stomach

Arteries of stomach  Short gastric arteries  Branches of splenic artery  through the gastrosplenic ligament  Supply the fundus of stomach.  Posterior gastric artery (72%)  Arise from the splenic artery  through the gastrophrenic ligament and supply the posterior wall of fundus of stomach

Venous drainage of stomach Right and left gastric veins empty directly into hepatic portal vein. Left gastroepiploic and short gastric veinsdrain into hepatic portal vein via the splenic vein. Right gastroepiploic vein drain into superior mesenteric vein

Venous drainage of stomach  Right and left gastric veins empty directly into hepatic portal vein.  Left gastroepiploic and short gastric veins drain into hepatic portal vein via the splenic vein.  Right gastroepiploic vein drain into superior mesenteric vein

Lymph drainage of stomach Accompany the A.along the 2 curvatures Rightand leftgastric LN 来 Rightand left gastroomental LN drain into pancreaticosplenic, pyloric LN, pancreaticoduodenal LN finally to the celiac LN. lymphatic metastasis
