anatomy, the superior mesenteric vein (SMV) is a blood vesselthat drains bloodfrom the small intestine( jejunumand ileum). At its termination behind the neck of the pancreas, the SMV combines with the splenic veinto form the hepatic portal vein. The SMV lies to the right of the similarly named artery, the superior mesenteric artery, which originates from the abdominal aorta.
Tributaries of the superior mesenteric vein drain the
large intestine, stomach, pancreasand 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
Thrombosis of the superior mesenteric vein is quite rare, but a significant cause of
mesenteric ischemiaand can be fatal. It is estimated that 10-15% of mesenteric ischemiais due to mesenteric thrombosis.ref|Tessier
