Artery: Splenic artery

The visceral surface of the spleen.

Branches of the celiac artery. (Lienal artery is an old term for splenic artery, and is visible at center. The spleen is at center right. The stomach has been flipped out to reveal the splenic artery, so the greater curvature is at the top in this diagram.)

In anatomy, the splenic artery (in the past called the lienal artery) 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.

The splenic artery gives off branches to the stomach and pancreas before reaching the spleen.

Branch	Description
branch to the pancreas	Multiple branches serving the pancreas. The largest is the arteria pancreatica magna
short gastric	upper part of greater curvature of the stomach
left gastroepiploic	middle of greater curvature of the stomach

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 right gastroepiploic artery, a branch of the gastroduodenal artery. The two gastroepiploic arteries anastomose with each other at that point.

Along its course, it is accompanied by a similarly named vein, the splenic vein, which drains into the portal vein.

Splenic artery aneurysms are rare^[1], but still the third most common abdominal aneurysm^[2] (after aneurysms of the abdominal aorta and iliac arteries).
