Arteria gastrica sinistra direkt aus der Aorta

Varianter,

separater Abgang der A. gastrica sinistra direkt aus der Aorta. Computertomographie axial, coronar und sagittal (MIP 13mm). Die im Vergleich zur A. lienalis und A. hepatica communis deutlich kleinlumigere A. gastrica sinistra entspringt zwischen der rechten und linken A. phrenica inferior aus der Aorta und zieht von dort nach ventral.

proximal splenic artery embolization in blunt abdominal trauma. a Schematic of collateral splenic perfusion via the left gastric (star) to short gastric pathway (curved arrows). Note that the normal direction of flow is reversed in the short gastric arteries. b 39 year old female with history of splenic laceration caused by motor vehicle accident 11 years prior which was treated with a subtotal splenectomy as well as splenic artery and vein ligation. Left gastric artery angiogram done for bleeding gastric varices demonstrates the left gastric to short gastric to spleen collateral pathway

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

It passes superiorly over the left crus of the diaphragm, approaching the esophageal opening of the diaphragm, giving off an esophageal branch to the distal esophagus, 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 hemorrhage is from the left gastric artery territory. In a patient with significant upper GI bleeding but no active bleeding site identified on angiography, prophylactic embolization of the left gastric artery may be performed. Upper GI embolization is well tolerated because of the rich collateral blood supply.
