It branches from the [[celiac artery]], and follows a course [[superior]] to the [[pancreas]]. ==Branches== The splenic artery gives off branches to the [[stomach]] and pancreas before reaching the spleen. {| class="wikitable" | '''Branch''' || '''Description''' |- | [[Pancreatic branches of splenic artery|branch to the pancreas]] || Multiple branches serving the [[pancreas]]. The largest is the [[arteria pancreatica magna]] |- | [[Short gastric arteries|short gastric]] || upper part of [[greater curvature of the stomach]] |- | [[left gastroepiploic artery|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. ==Vein== Along its course, it is accompanied by a similarly named vein, the [[splenic vein]], which drains into the [[portal vein]]. ==Pathology== Splenic artery [[aneurysm]]s are rare{{ref|Abbas}}, but still the third most common abdominal aneurysm{{ref|Jamsheer}} (after aneurysms of the [[abdominal aorta]] and [[iliac artery|iliac arteries]]). ==Additional images== <gallery> Image:Gray532.png|The celiac artery and its branches.
