The splenic artery is one of the three branches of the celiac trunk, which supplies the spleen as well as large parts of the stomach and pancreas.

Gross anatomy
Origin and course
The splenic artery is one of the terminal branches of the celiac trunk, passing left from the celiac axis across the left crus of the diaphragm and left psoas muscle. It is a tortuous artery, running superior to the pancreas before turning forward into the splenorenal ligament to the hilum of the spleen. The splenic vein accompanies it inferoposteriorly.
Near the splenic hilum the splenic artery gives off a superior polar branch before dividing into superior and inferior terminal branches or lobar branches. These lobar branches further divide into two to six intrasplenic segmental branches which anastamose within the spleen.
Branches and supply
-
pancreatic branches including the dorsal pancreatic artery, transverse pancreatic artery, and greater pancreatic artery (arteria pancreatica magna)
supply neck, body, and tail of the pancreas
-
arising before the splenic artery enters the splenic hilum
run in the gastrosplenic ligament to supply the fundus and upper part of greater curvature of the stomach, and anastomose with the left gastric artery over the fundus
supplies cardia and fundal regions of the stomach
-
runs in the greater omentum along the greater curvature of the stomach to anastomose with the right gastroepiploic artery
Variant anatomy
separate origin from the abdominal aorta rather than the celiac trunk (~8%)
History and etymology
In the past, it was also called the lienal artery 4.
