Ultrasound Scan:
May Thurner Assessment

May-Thurner syndrome, also known as iliac vein compression syndrome or Cockett syndrome, is a condition characterised by the compression or obstruction of the left iliac vein by the adjacent right iliac artery. This compression can lead to venous stasis, reduced blood flow, and the potential development of deep vein thrombosis (DVT) in the affected leg.

We request a 4 hr fast for this study.

Eating creates a gas that ultrasound is unable to scan through and may obstruct structures we need to see.

​

This scan usually takes between 20- 30 minutes.

​

This ultrasound will require direct contact with the abdomen. We generally don't need you to remove any clothing, but will request for your shirt and jumper to be lifted up, your belt loosened and your trousers shuffled down to your hips. We will ask for you to lie on your back on our examination bed. During the scan we will apply ultrasound gel to your abdomen and use the ultrasound machine to look at the the arteries and veins to assess for any compression. You will hear noises from the ultrasound machine; this is all normal and is the sound of the blood flow moving through your arteries.

Investigation of May Thurner Syndrome involves the assessment of the common iliac veins, internal ilaic veins and external iliac veins. The purpose of this study is to rule out any evidence of impingement; specifically that involving the compression of the left common iliac vein by the right common iliac artery.

May-Thurner syndrome, also known as iliac vein compression syndrome, is a condition caused by the compression or obstruction of the left iliac vein by the adjacent right iliac artery. While the exact cause of May-Thurner syndrome is not fully understood, there are several recognised risk factors that may increase the likelihood of developing this condition. These risk factors include:

Gender

May-Thurner syndrome is more commonly observed in females compared to males. The anatomical differences in the pelvis, such as the position of the iliac vessels, may contribute to this gender disparity.

Age

May-Thurner syndrome typically presents in young to middle-aged adults, although it can occur at any age. The exact age range of highest risk is not well defined.

Hereditary factors

There may be a genetic component to May-Thurner syndrome. Individuals with a family history of venous disorders, such as deep vein thrombosis (DVT) or varicose veins, may be at a higher risk of developing May-Thurner syndrome.

Pregnancy

Pregnancy is associated with hormonal and anatomical changes that can increase the risk of developing venous disorders, including May-Thurner syndrome. The increased blood volume, hormonal influences, and pressure on the pelvic vessels during pregnancy can contribute to the development or worsening of iliac vein compression.

​

History of deep vein thrombosis (DVT)

Previous episodes of deep vein thrombosis in the affected leg or pelvis may lead to scarring and narrowing of the iliac vein, increasing the risk of May-Thurner syndrome.

May-Thurner syndrome, also known as iliac vein compression syndrome, is a condition characterized by the compression or obstruction of the left iliac vein by the overlying right iliac artery. This can lead to various symptoms and complications. Here are some common symptoms associated with May-Thurner syndrome:

Leg pain or discomfort

Many individuals with May-Thurner syndrome experience pain or discomfort in the left leg. This pain is typically described as a dull ache or heaviness in the thigh, calf, or lower leg. The pain may worsen with prolonged standing or walking.

Swelling (edema)

Edema, or swelling, can occur in the left leg due to impaired venous blood flow caused by the compression of the iliac vein. The swelling may be more pronounced in the ankle, calf, or lower leg.

Varicose veins

May-Thurner syndrome can lead to the development of varicose veins in the left leg. These are enlarged, twisted veins that may be visible on the surface of the skin and can cause discomfort or aching sensations.

Deep vein thrombosis (DVT)

In some cases, May-Thurner syndrome can increase the risk of deep vein thrombosis, which is the formation of blood clots in the deep veins of the leg. Symptoms of DVT may include pain, warmth, redness, and swelling in the affected leg.

Leg ulcers

In severe cases of May-Thurner syndrome, chronic venous insufficiency and impaired blood flow can lead to the development of leg ulcers. These are open sores that typically occur around the ankle or lower leg and can be slow to heal.
