What is May-Thurner Syndrome?
May-Thurner Syndrome (MTS), sometimes called Iliac Vein Compression Syndrome, primarily affects women between the ages of 20 and 50. Women diagnosed with MTS will have compression of the left iliac vein leading to a decrease in drainage of the left leg. If left untreated, this may lead to the formation of a deep vein thrombosis (blood clot). The DVT can restrict blood flow causing pain, swelling and sometimes varicose veins in the left leg. May-Thurner Syndrome presents on the left side, though cases where there are right sided symptoms have been reported.
