The left gastric artery (LGA) is the smallest and first branch of the coeliac artery.
Gross anatomy
The left gastric artery passes superiorly over the left crus of the diaphragm, approaching the oesophageal opening of the diaphragm, giving off an oesophageal branch to the distal oesophagus, then enters the lesser omentum to pass along the lesser curvature of the stomach. It anastomoses along the lesser curvature with the right gastric artery from the common hepatic artery, and over the fundus of the stomach with the short gastric arteries from the splenic artery.
Approximately 85% of upper gastrointestinal 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.
Variant anatomy
- arise directly from the aorta (2%-6%) 4
- source of one or both phrenic arteries (5%) 4
- source of an accessory or replaced left hepatic artery (20%-30%) 4
- accessory left gastric artery (common) 4
