Mesenteric Venous Thrombosis – Causes, Symptoms, Diagnosis, & Treatment
What is mesenteric venous thrombosis?
Mesenteric venous thrombosis (MVT) refers to the formation of a blood clot in one or more of the major veins that drain blood from the intestine. MVT blocks blood flow in the affected mesenteric vein. If left untreated, this condition can lead to serious complications.
MVT affects middle-aged or older adults and is more common in men than women.
What causes mesenteric venous thrombosis?
What causes mesenteric venous thrombosis (MVT) is not known to doctors. However, certain diseases that cause inflammation of the tissues surrounding the mesenteric veins can lead to MVT.
The following disease can cause inflammation of the surrounding tissues of a mesenteric vein:
- Cancer of the abdomen
- Liver disease with cirrhosis
What are the symptoms of mesenteric venous thrombosis?
The following are the common symptoms of MVT:
- Abdominal pain that gets worse after eating
- Nausea and vomiting
- Bloody stools
How is mesenteric venous thrombosis diagnosed?
Your doctor may do aCT scan to diagnose mesenteric venous thrombosis. The doctor may also order the following other tests:
- Abdominal MRI
- Ultrasound of the abdomen and mesenteric veins
- Angiogram (to check blood flow to the intestine)
How is mesenteric venous thrombosis treated?
Mostly, doctors treat MVT with blood thinners, such as heparin or related medicines if there is no bleeding. Sometimes, doctors treat it with clot-dissolving medicines. This procedure is called thrombolysis, which involves delivering the medicines directly into the clot.
Sometimes, doctors remove the clot surgically with a procedure called thrombectomy.
If the doctor finds signs of peritonitis (a severe infection of the inner wall of the abdomen), he/she may remove the intestine surgically.
