Medical staff on operating roomPeople suffering from May-Thurner Syndrome (MTS) often experience a compression on their iliac veins. This compression leads to blood pooling, clot formation, and loss of adequate blood supply to the lower limbs, especially on the left leg.

But there’s hope for these patients. The disease is treatable and manageable through anti-coagulation medicines, angioplasty, and vascular stenting. How do May-Thurner Syndrome stents work, and how successful is this method of managing the disease?

How Does Blood Circulation Work?

The blood carries oxygen and transports it to the entire body through the body’s arteries. After the body takes up the oxygen from the blood, this now oxygen-deficient blood travels back to the heart and lungs through the body’s veins to refill itself of oxygen.

Now, blocked arteries and veins can become a major problem in May Thurner Syndrome. The condition causes vein compression, followed by blood pooling in the veins, which ultimately leads to the formation of blood clots.

What Is Stenting?

Stenting is a procedure done to keep blocked blood vessels open for as long as possible. It uses a tiny mesh tube that is inserted into the vessel walls, done adjacent to angioplasty, wherein the blocked blood vessels are reopened using an inflatable balloon catheter.

Why Is Stenting Needed for May Thurner Syndrome?

Blood clots are main complications of MTS. Clots impede blood flow and damage the vessel walls, leading to its collapse. Stenting opens up the blocked vessels, keep them in that opened state, and allow the normal flow of blood circulation to return. They also prevent bursting of the vessels.

Does Stenting Work?

Venous stenting works well in maintaining vein patency and preventing vein collapse caused by MTS. May-Thurner Syndrome patients with a stent placed in their veins have at least 70-80% chances of not having a recurrence of vein re-occlusion.

In a nutshell, performing stenting in conjunction with angioplasty yields positive results in treating blocked and collapsed veins caused by May-Thurner Syndrome. Stenting is a relatively safe procedure and works well with most MTS patients.
