What is May-Thurner Syndrome (MTS)?

May-Thurner Syndrome (MTS) is also known as Cockett Syndrome or Iliac Compression Syndrome. Iliac vein compression is common; it’s estimated to occur in 1 in 5 people. May-Thurner syndrome occurs when your right iliac artery applies pressure on your left iliac vein at the point where they cross in your pelvis area. Imagine stepping on a water hose while it’s turned on. Your left iliac vein is one of the main veins in your pelvis that carries blood back to your heart.

When this compression happens on your left iliac vein, it interrupts the blood flow and causes the blood to back up in your left leg resulting in swelling and potentially putting you at risk for deep vein thrombosis or DVT. DVT occurs when large blood clots form in the deep veins in your legs.

Treatment Options for May-Thurner Syndrome (MTS)

There are several ways to diagnose May-Thurner Syndrome including imaging tests like MRI, CT scan, ultrasound or venogram. Treatment for MTS includes:

Angioplasty and stenting – This is a minimally invasive procedure that can be done in the outpatient setting. Your doctor will administer minimal anesthesia to make you comfortable and then access your vein through your groin area. Under the guidance of an x-ray, they will advance a balloon over a wire and place the balloon in the area of the compression.
Once they have confirmed the correct positioning, they will inflate the balloon to try to open the area. After the balloon is deflated, they will remove it and then place a stent in the same area. The stent will offer scaffolding that will keep the vein open and provide resistance against the pressure of the iliac artery compression.
Bypass surgery – In some cases your disease may need to be treated surgically. In this procedure you will be under full anesthesia. Your physician will use a conduit or a vein from another part of your body to build a new route for the blood to flow around the area of compression.

If you have developed deep vein thrombosis (DVT) as a result of your May-Thurner Syndrome, you will also be treated with DVT protocol.
