In
human anatomy, the superior mesenteric vein (SMV) is a blood vessel that drains blood from the small intestine (jejunum and ileum). Behind the neck of the pancreas, the superior mesenteric vein combines with the splenic vein to form the portal vein that carries blood to the liver. The superior mesenteric vein lies to the right of the similarly named artery, the superior mesenteric artery, which originates from the abdominal aorta
.
Structure
Tributaries of the superior mesenteric vein drain the
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
The superior mesenteric vein combines with the splenic vein to form the portal vein.[1][2]
Clinical significance
mesenteric ischemia and can be fatal. It is estimated that 10–15% of mesenteric ischemia is due to mesenteric thrombosis.[3]
