Splenic Artery

Sunday, May 29, 2011

The splenic artery is an artery which arises from the celiac trunk and supplies oxygen-rich blood to the spleen, running superior to the pancreas. Along its course, before reaching the spleen, the splenic artery gives off branches to the stomach, pancreas, duodenum, and liver. Splenic artery aneurysms are rare, but still the third most common abdominal aneurysm (after aneurysms of the abdominal aorta and iliac arteries). They may occur in pregnant women in the 3rd trimester and rupture carries a maternal mortality of greater than 50% and a fetal mortality of 70% - 90%. Risk factors include smoking and high blood pressure.
