The splenic artery is, along with the gastric and common hepatic arteries, one of the three main branches of the celiac artery, which in turn branches from the abdominal aorta, the largest artery in the abdomen. The splenic artery is responsible for supplying oxygenated blood to the spleen, but also has several branches that deliver blood to the stomach and pancreas. The branches of the splenic artery are the short gastric, the left gastroepiploic, the posterior gastric, and the branches to the pancreas. The short gastric arteries consist of five to seven small branches that run along the greater curvature of the stomach. The left gastroepiploic artery is the largest branch of the splenic artery and runs towards the interior of the stomach through the greater omentum. The branches to the pancreas consist of numerous small blood vessels that run behind the upper border of the pancreas, supplying it with blood. Splenic artery aneurysms are the third most common abdominal aneurysm and can occur during the third trimester in pregnant women.
