What is May-Thurner Syndrome?

May-Thurner syndrome is a condition that occurs due to an abnormality in the venous system. First published in 1957 by Dr. May and Dr. This syndrome, described by Thurner, occurs as a result of compression of the left iliac artery in front of the right iliac vein. The iliac artery is the main artery in the pelvic area, and the iliac veins are the large veins that carry blood from the legs.


May-Thurner syndrome usually occurs when the left iliac artery puts pressure in front of the right iliac vein, causing a narrowing or blockage of that vein. This condition can block venous blood flow back to the heart from the legs and lead to lower extremity venous insufficiency, deep vein thrombosis (DVT), or pulmonary embolism (blockage of the lung artery).

Symptoms may include leg pain, swelling, a feeling of heaviness, varicose veins, and skin changes on the legs. It can also cause pelvic congestion syndrome in women, causing pain during menstruation, pain during intercourse, or chronic groin pain. Diagnosis is usually made with imaging tests such as ultrasound or venography. Treatment is usually done by endovascular methods. This may involve catheter-based procedures to widen the vessels and restore blood flow.

May-Thurner syndrome is a condition that usually affects women within a certain age range, but it can also occur in men. Risk factors may include poor posture such as sitting or standing for long periods of time, venous problems in the family, pregnancy, and use of birth control pills.
