May Thurner Syndrome: Causes, Symptoms and Treatment

Deep Vein ThrombosisThe blood vessels are very important in the body because they’re the ones carrying oxygen and nutrients to the different parts of the body. Since they’re being used 24/7, the vessels can also suffer from damage and certain conditions that could predispose a person to vascular diseases.

For instance, the lumen of the vessel could be filled up with plaques of cholesterol and this would inhibit the smooth travel of blood. This condition may lead to increased blood pressure, heart disease, and even stroke.

Other conditions include deep vein thrombosis and post-thrombotic syndrome, which could also lead to various conditions like blood pooling in the legs and embolism. Another condition involving the veins is May-Thurner Syndrome (MTS).

What Is May-Thurner Syndrome?

MTS happens when the left iliac vein is compressed by the right iliac artery, which increases the risk of deep vein thrombosis (DVT). It is a rarely diagnosed condition wherein patients develop iliofemoral deep venous thrombosis due to an anatomical problem in the right common iliac artery.

Common Signs And Symptoms

Most people with May-Thurner syndrome have no symptoms at all because of other, smaller veins that bypass the narrowed area become enlarged and drain blood from the legs very effectively. For others, however, they may have symptoms like leg swelling and pain and other symptoms that are termed as chronic venous insufficiency. In other people, the symptoms may be linked to deep vein thrombosis, which is a common complication of MTS.



One of the surgical options to treat MTS is stenting. A May Thurner syndrome stent works to hold the vein open and relieve the blockage caused by the compressing artery. This works and it’s minimally invasive which only requires a small incision and a shorter recovery time.

Bypass Surgery

In bypass surgery, the blood flow is rerouted around the blocked or narrowed vein using a graft.

Problems in the blood vessels should be detected and treated early. One of the most important things to remember is that prevention of the disease is imperative to prevent serious and potentially fatal complications like stroke, heart attack, pulmonary embolism, and leg gangrene.
