In
human anatomy, the splenic artery or lienal artery, an older term, is the blood vessel that supplies oxygenated blood to the spleen. It branches from the celiac artery, and follows a course superior to the pancreas
. It is known for its tortuous path to the spleen.
Structure
The splenic artery, the largest branch of the celiac trunk, gives off branches to the stomach and pancreas before reaching the spleen.
| Branch | Description |
| branches to the pancreas | multiple branches serving the pancreas including greater pancreatic artery and dorsal pancreatic artery. |
| short gastric | upper part of greater curvature of the stomach and fundus of the stomach
|
| left gastroepiploic | middle of greater curvature of the stomach |
| posterior gastric | posterior of stomach, gastric region superior to the splenic artery |
Note that the branches of the splenic artery do not reach all the way to the lower part of the greater curvature of the stomach. Instead, that region is supplied by the
anastomose
with each other at that point.
Relations
The splenic artery passes between the layers of the
lienorenal ligament. Along its course, it is accompanied by a similarly named vein, the splenic vein, which drains into the hepatic portal vein
.
Clinical significance
Splenic artery
endovascular treatment may be considered.[5]
