The inferior mesenteric vein (IMV) is a blood vessel that drains blood from the large intestine. It is a crucial component of the venous system in the abdomen.

Anatomy[edit | edit source]

The inferior mesenteric vein originates in the rectum and ascends through the abdomen, collecting blood from the sigmoid colon, descending colon, and the left colic flexure. It typically joins the splenic vein, which then combines with the superior mesenteric vein to form the portal vein.

Tributaries[edit | edit source]

The main tributaries of the inferior mesenteric vein include:

Function[edit | edit source]

The primary function of the inferior mesenteric vein is to drain deoxygenated blood from the lower part of the large intestine. This blood is then transported to the liver via the portal vein for detoxification and nutrient processing.

Clinical significance[edit | edit source]

The inferior mesenteric vein is significant in various medical conditions, including portal hypertension and colorectal cancer. Its involvement in the portal venous system makes it a critical vessel in the context of liver disease and gastrointestinal bleeding.
