May-Thurner syndrome (MTS) is defined as extrinsic venous compression by the arterial system against bony structures in the iliocaval territory. MTS is also referred to as iliocaval venous compression syndrome, iliac vein compression syndrome, Cockett's syndrome, and venous spur.
May-Thurner anatomy (MTA) is an anatomical variant characterized by external compression of the common iliac vein (CIV) by the overlying iliac artery anteriorly and the underlying vertebral body posteriorly. This can lead to venous intimal hyperplasia and scarring, blood flow stasis, and DVT.
Sometimes, the artery can compress the vein at that point. This creates the same effect as stepping on a garden hose; it narrows the vein and slows the flow of blood, which may cause swelling in the left leg as well as other symptoms. This iliac compression is called May-Thurner syndrome.
May-Thurner syndrome (MTS) refers to compression of the left common iliac vein (CIV) by the common iliac artery. Although this is typically manifested as acute left lower extremity deep venous thrombosis, MTS is a rare cause of pelvic congestion syndrome.
Diagnosing May-Thurner syndrome To diagnose May-Thurner syndrome, your doctor will: Perform a physical exam. Ask about your medical history and symptoms. Use an imaging test — like an ultrasound, MRI, or venogram — to confirm your diagnosis.
Iliac vein compression, also known as May-Thurner syndrome, occurs when the main vein of your left leg – the left iliac vein – becomes constricted by the main artery in your right leg – the right iliac artery.
May-Thurner Syndrome is a vascular compression disorder caused by a pinched vein near the pelvis (iliac vein) is pinched, preventing blood from flowing normally through the legs. It is also referred to as left iliac vein compression. When the blood flow slows, it can result result in swelling of the legs.
May-Thurner Syndrome is one underlying cause of a common condition. This anatomic finding has been shown to be present in more than 20% of the population.
May-Thurner syndrome: High output cardiac failure as a result of iatrogenic iliac fistula.
Why Do I Have May-Thurner Syndrome? This condition is congenital but not hereditary and is more common in women than men. It shows up more frequently in young women taking birth control medication, as women age or as they gain weight.
May-Thurner syndrome most commonly involves the right iliac artery and the iliac vein draining the left lower extremity, but we often see involvement of the right lower extremity, as well, and/or involvement of both lower extremities.
