Left gastric artery

Dr Craig Hacking and Dr Donna D'Souza et al.

The left gastric artery is the smallest and first branch of the coeliac artery.  

It passes superiorly, giving off an oesophageal branch to the distal oesophagus, then enters the lesser omentum to pass along the lesser curvature of the stomach.  Anastomoses along the lesser curvature with the right gastric artery from the common hepatic artery, and over the fundus with the short gastric arteries from the splenic artery.

Approximately 85% of upper gastro-intestinal haemorrhage is from the left gastric artery territory. In a patient with significant upper GI bleeding but no active bleeding site identified on angiography, prophylactic embolisation of the left gastric artery may be performed. Upper GI embolisation is well tolerated because of the rich collateral blood supply.
