Mesenteric venous thrombosis is a blood clot in the major veins that drain blood from the intestine.
Causes, incidence, and risk factorsMesenteric venous thrombosis is a clot that blocks blood flow in the mesenteric veins, one of two veins through which blood leaves the intestine. The condition interrupts the blood supply to the intestine and can result in damage to the intestines.
Mesenteric venous thrombosis has a variety of causes. Many of the diseases that lead to this condition cause swelling (inflammation) of the tissues surrounding the veins, including:
- Appendicitis
- Cancer
- Diverticulitis
- Liver disease with cirrhosis
- Pancreatitis
Patients who have blood clotting disorders that make the blood more likely to stick together (clot) have a higher risk for mesenteric venous thrombosis.
Symptoms- Abdominal pain, which may get worse after eating and over time
- Diarrhea
- Vomiting
A CT scan is the main test used to diagnose mesenteric venous thrombosis.
Other tests may include:
- Angiogram(studying the blood flow to the intestine)
- MRI
- Ultrasound of the abdomen and mesenteric veins
Blood thinners (most commonly heparin) are used to treat mesenteric venous thrombosis. In some cases, medicine can be delivered directly into the clot to dissolve it. This procedure is called thrombolysis.
Sometimes the clot is removed with a type of surgery called thrombectomy.
If you have signs and symptoms of peritonitis, you will usually need surgery to remove the intestine. After surgery, you may need an ileostomy (opening from the small intestine into a bag on the skin) or colostomy (an opening from the colon into the skin).
Expectations (prognosis)How well you do depends on the cause of the thrombosis. Getting treatment for the cause before the intestine has died can result in a good recovery.
ComplicationsIntestinal ischemia is a serious complication of mesenteric venous thrombosis. Some or all of the intestine dies because of poor blood supply.

What is venous thrombosis prevention?
Venous thrombosis prevention is a means to prevent blood clots from forming in veins within the body.
What is the Difference between venous thromboembolism and deep vein thrombosis?
The difference is that venous thrombosis refers to a blood clot that forms in a vein and deep vein thrombosis is a clot that forms in the deep veins of a leg.
What does D.V.T. stand for?
DVT stands for deep vein (venous) thrombosis. So obvious
What is the simple subject and simple predicate of the elderly patient's deep venous thrombosis was treated with Coumadin?
elderly patient
What are possible complications of sclerotherapy?
Venous thrombosis. A potentially serious complication, thrombosis refers to the formation of blood clots in the veins. Severe inflammation. Pain after the procedure lasting several hours or days.
What risk is connected with undergoing an orchiectomy?
They include deep venous thrombosis, heart or breathing problems, bleeding, infection, or reaction to the anesthesia.
Why do mesenteric veins not connect directly to the vena cava?
because venous blood from te mesentery, spleen and pancreas are filtered by the liver before it returns to the heart.
What are the differences between arterial and venous thrombosis?
Arterial thrombosis is associated with an atherosclerotic plaque being ruptured. It is hence associated with high pressure arteries. The thrombus is made of many platelets and contains little fibrin. It can lead to stroke or acute myocardial infarction in the most severe cases. Venous thrombosis is caused by vessel injury or static blood flow in a low-pressure venous system. The thrombus is made of fibrin and red blood cells with very little platelets. It can detach to form an embolus and may cause pulmonary embolism.
Protein what is protein S deficiency?
Protein S deficiency is associated with increased risk for venous thrombosis. This is a clotting disorder involving Vitamin K.
What is Vascular System Diseases?
This includes any disease that affects your circulatory system. Peripheral artery disease, Aneurysm (most common is Aorta), Renal artery disease, Raynaud's disease, Buerger's disease, Peripheral venous disease, Vericose veins, Venous blood clots, Deep vein thrombosis, Pulmonary thrombosis, and Chronic venous insufficiency.reference:Gerrard J. Tortora, Bryan Derrickson, Principles of Anatomy and Physiology, (John Wiley and Sons, New Jersey, 2009). pp. 703-773.
What is a venous Doppler?
This is usually used to test for deep vein thrombosis, where sound waves are bounced into a vein and reflected off before being analysed by a computer to give an idea of blood flow.
Venous thrombosis - series?
Normal anatomyVeins carry blood back to the heart from the tissues. Blood flowing in the veins is under lower pressure and moves more slowly than blood flowing in the arteries. Blood is therefore more likely to clot in the veins, thus blocking the flow through the veins.IndicationsBlood clot formation in the veins is called venous thrombosis. Venous thrombosis most commonly forms in the veins of the legs. Risk factors for venous thrombosis include prolonged bed rest or immobility, as can be necessary after surgery, cancer, and estrogen therapy.Procedure, part 1Venous thrombosis can cause swelling and pain of the leg in which it forms. Large clots can also break free and travel to the heart and lungs, where they can cause cardiac arrest and sometimes death. This is called pulmonary embolism.Procedure, part 2Venous thrombosis of the legs is diagnosed by ultrasound. Treatment usually involves medication to thin the blood and dissolve the thrombosis. Two common medications are heparin and coumadin. If patients are not candidates for blood-thinning medication (such as patients with a history of stroke or bleeding), a filter is placed in the large vein leading from the leg to the heart, to catch any clot that may embolize up toward the heart. These filters can be inserted through a catheter inserted in the veins of the groin.AftercarePost-operative patients are at risk for pulmonary embolism because of the time spent in bed after surgery. One method for reducing the risk of venous thrombosis is the use of sequential compression devices (SCDs). These are stockings that wrap around the legs and periodically inflate and deflate with air. In part, this prevents the formation of thrombosis in the leg veins by increasing blood flow through the veins. The use of SCDs and early ambulation after surgery greatly reduces the risk of venous thrombosis and pulmonary embolism. Walking immediately after surgery also reduces the risk of thrombosis and pulmonary embolism. SCDs are used after many major surgeries until patients are able to walk regularly on their own.Reviewed ByReview Date: 02/13/2011David C.
