The splenic artery is the largest branch of the celiac trunk.


The splenic artery has a very distinctive tortuous appearance and ranges in length from 8 to 32 cm. It first travels anteroinferiorly towards the pancreas. It then courses laterally, posterior to the upper portion of the body and tail of the pancreas. It passes anterior to the left kidney and left suprarenal gland before it enters the hilum of the spleen.


As it travels towards the hilum of the spleen, the splenic artery gives off pancreatic branches (dorsal pancreatic artery, greater pancreatic artery, and the artery to the tail of the pancreas) and gastric branches (5–7 short gastric arteries and the left gastroomental artery). Additionally, in approximately 25.5% of cases a posterior gastric artery arises from the splenic artery (and arises from the left gastric artery in 41.8% of individuals) (Loukas et al., 2007).

As the splenic artery reaches the splenic hilum, it divides into two or three branches that supply the spleen.

Supplied Structures

The pancreatic branches supply the body and tail of the pancreas. The short gastric branches, the posterior gastric artery and the left gastroomental artery supplies the stomach and the greater omentum. The terminal branches of the splenic arteries supply the spleen.

Arteries are vessels transporting blood between heart, tissues, and other organs in order to supply them with nutrition and oxygen.
