Treatment is mainly medical using anticoagulation as soon as the diagnosis is made even in the presence of bleeding or the need for surgical intervention. The duration of treatment is based on the presence of identifiable reversible risk factor in which case anticoagulation can be given for 3–6 months.
What is inferior mesenteric vein thrombosis?
Mesenteric venous thrombosis (MVT) describes acute, subacute, or chronic thrombosis of the superior or inferior mesenteric vein or branches. MVT may present with acute abdominal pain or may be an asymptomatic incidental finding on abdominal imaging.
What does the inferior mesenteric vein do?
The inferior mesenteric vein (IMV) drains the descending colon, the sigmoid colon, and the rectum through the left colic vein, the sigmoid branches, and the superior rectal vein, respectively. The IMV joins the splenic vein, which then joins the SMV to form the portal vein. The portal vein enters the liver.
What is mesenteric venous thrombosis?
Mesenteric venous thrombosis (MVT) is a blood clot in one or more of the major veins that drain blood from the intestine. The superior mesenteric vein is most commonly involved.
How is mesenteric vein thrombosis diagnosed?
Diagnosing Mesenteric Venous Thrombosis Diagnosis is usually based on your symptoms and imaging tests. Typically, a CT scan is used. This test uses X-rays to create cross-sectional images of the abdomen. Other imaging tests may include an ultrasound or MRI scan of the abdomen.

Where does the inferior mesenteric vein go?
In human anatomy, the inferior mesenteric vein (IMV) is a blood vessel that drains blood from the large intestine. It usually terminates when reaching the splenic vein, which goes on to form the portal vein with the superior mesenteric vein (SMV).
Is blood clot in stomach serious?
Abdominal blood clots are rare. But blood clots, including clots in your abdominal region, are serious, especially if the clot breaks away and lodges in the lungs, causing what’s known as a pulmonary embolism.

The inferior mesenteric vein usually drains into the splenic vein; however, anatomical variants where it drains to the superior mesenteric vein or at the splenoportal angle are not uncommon.
What is the function of the inferior mesenteric vein?
As a blood vessel, the inferior mesenteric vein (IMV) drains blood away from the descending colon, rectum, and sigmoid, which are all parts of the large intestine. The IMV branches off the portal vein, which also branches into the superior mesenteric vein.
