May-Thurner Syndrome (MTS), also known as Iliac Vein Compression Syndrome, is an asymmetrical swelling of the legs – the left leg swells but the right leg does not. MTS is a rare condition, but one that the vascular surgeons at USA Vein Clinics are experienced in treating. They treat the underlying condition causing the syndrome, thereby relieving the leg swelling and pain. Leg swelling & pain treatments are one of the many vein treatment that USA Vein Clinics offer.

May-Thurner Syndrome occurs because the left iliac vein is compressed by the right iliac artery. (The iliac veins and arteries lie deep in the pelvis). This compression of the left iliac vein impedes venous drainage of the left leg leading to intractable swelling.

How do I know if I have MTS?

Many people do not know they have May-Thurner Syndrome Patients with intractable swelling of venous ulcerations of the left leg should be evaluated by an experienced physician.

What is the treatment for MTS?

MTS is treated by relieving the vein compression with a stent.


Angioplasty and stenting

Angioplasty and stenting of the iliac vein is a minimally invasive treatment that widens the vein. The procedure inflates the vein in order to widen it and increase blood flow and then a stent – a small, mesh-like tube – is placed in the vein to keep it open. The stent stays in the vein permanently.
This treatment is effective in the treatment of MTS because the stent keeps the compressed iliac vein open and improving venous drainage from the left leg.

This procedure is performed in the USA Vein Center offices.
