Right gastric aery originates from the hepatic aery just distal to the origin of gastroduodenal aery. It turns to the left and runs upwards along the the lesser curvature of the stomach and ends by anastomosing with the left gastric aery which is a branch of the coeliac trunk. Coeliac trunk: Arises at the level of interveebral disc between T12 and L1 veebrae. It is an unpaired branch of the abdominal aoa that arises from its ventral/anterior aspect (front) just below the aoic opening of diagphragm. Branches: Left Gastric aery (Smallest branch) Common Hepatic aery Splenic Aery (Largest branch of trunk) Ends by anastomosing with right gastric aery (Right Gastric aery is a branch of the hepatic aery) Common hepatic aery is a direct branch of the celiac trunk till the origin of gastroduodenal aery. The pa distal to this origin is termed proper hepatic aery Sho gastric aeries (5-7) Left gastroepiploic aery Numerous pancreatic branches Aeria pancreaticamagna Aeria cauda pancreatic Splenic hila branches Common Hepatic aery gives off a branch called Gastroduodenal aery and continues as the Hepatic aery proper. Right gastric aery originates from the hepatic aery just distal to the origin of gastroduodenal aery. Thus the right gastric aery may be termed as a branch of the hepatic aery proper rather than the common hepatic aery. Hepatic aery Branches: Gastro-duodenal aery Right gastric Aery Hepatic Aery proper Right gastroepiploic aery Superior pancreaticoduodenal aery Right gastric aery (ends by anastomosing with the left gastric aery) Hepatic aery proper ends by dividing into left and right hepatic aeries Right hepatic aery Left hepatic aery (cystic aery) is a branch of the right hepatic aery Ref: Vishram Singh 2nd edition Pgno: 120
