, the superior mesenteric vein
(SMV) is a blood vessel
that drains blood
from the small intestine
). 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 named artery, the superior mesenteric artery
, which originates from the abdominal aorta
Tributaries of the superior mesenteric vein drain the large intestine
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
