Superior mesenteric vein

From Wikipedia, the free encyclopedia

Vein: Superior mesenteric vein

The portal vein and its tributaries. The superior mesenteric vein and splenic vein. Leinal vein is an old term for splenic vein. Anatomical position.

In anatomy, the superior mesenteric vein (SMV) is a blood vessel that drains blood from the small intestine (jejunum and ileum). At its termination behind the neck of the pancreas, the SMV combines with the splenic vein to form the hepatic portal vein. The SMV lies to the right of the similarly name artery, the superior mesenteric artery, which originates from the abdominal aorta.

[edit] Branches

Tributaries of the superior mesenteric vein drain the large intestine, stomach, pancreas and appendix and include:

Right gastro-omental vein (also known as the right gastro-epiploic vein)
inferior pancreaticoduodenal veins
veins from jejunum
veins from ileum
middle colic vein - drains the transverse colon
right colic vein - drains the ascending colon
ileocolic vein

[edit] Disorders

Thrombosis of the superior mesenteric vein is quite rare, but a significant cause of mesenteric ischemia and can be fatal. It is estimated that 10-15% of mesenteric ischemia is due to mesenteric thrombosis.^[1]
