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.
Calling your health care providerCall your health care provider if you have severe or repeated episodes of abdominal pain.

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 is venous thrombosis prevention?
Venous thrombosis prevention involves measures such as staying active, avoiding prolonged periods of immobility, wearing compression stockings, and taking anticoagulant medications if necessary. It is important to manage risk factors such as obesity, smoking, and certain medical conditions to reduce the likelihood of developing venous thrombosis.
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.
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 risk is connected with undergoing an orchiectomy?
They include deep venous thrombosis, heart or breathing problems, bleeding, infection, or reaction to the anesthesia.
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.
What is venous imaging?
Venous imaging refers to imaging techniques used to visualize veins in the body. This can include methods like Doppler ultrasound, venography, magnetic resonance venography (MRV), and computed tomography venography (CTV), which help in diagnosing venous disorders like deep vein thrombosis, varicose veins, and venous insufficiency.
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 the purpose of a venous Doppler test?
A venous Doppler test is performed to assess blood flow in the veins, particularly to diagnose conditions like deep vein thrombosis (DVT) or venous insufficiency. It uses sound waves to create images of blood flow in the veins and can help in determining if there are any clots or blockages present.
