What Is May-Thurner Syndrome?

May-Thurner Syndrome (MTS), also called Iliac Vein Compression Syndrome, is a condition that causes the left leg to swell, but not the right leg.

What Causes May-Thurner Syndrome?

MTS is caused when the right iliac artery compresses the left iliac vein. This restricts the blood flow out of the left leg and leads to swelling. While MTS may not cause immediate harm, it can lead to the development of more serious conditions like Deep Vein Thrombosis (DVT). DVT is a blood clot that causes partial or full vein blockage.

How Do I Know If I Have MTS?

Unfortunately, MTS does not usually have any warning signs or symptoms. The most common sign you have May-Thurner Syndrome is the development of DVT.

How is MTS Treated at USA Vein Clinics?

Our treatment is non-surgical and is performed in our outpatient clinics. Treatment for May-Thurner Syndrome involves inflating the vein so that it widens and increases blood flow. After the vein is widened, a stent (mesh-like tube) is permanently placed in the vein to keep it open. This treatment effectively treats MTS by leaving the vein open for efficient venous drainage from the left leg.
