May Thurner Syndrome

May-Thurner Syndrome (MTS): Understanding Compression

May-Thurner Syndrome (MTS), also known as iliac vein compression syndrome, is a condition where the left iliac vein (a large vein in the pelvis) is compressed by the overlying right iliac artery. This compression can restrict blood flow and increase the risk of developing a deep vein thrombosis (DVT) in the left leg.

Important Distinction: MTS vs. Typical DVT

While MTS can cause DVTs, not all DVTs are caused by MTS. DVTs can have other  causes like inactivity, surgery, or medical conditions that affect blood clotting. Accurate diagnosis is key for identifying the right treatment approach.

Key Takeaway

If you experience persistent leg swelling or pain, particularly on the left side, seek medical evaluation. Early diagnosis and treatment of MTS can significantly reduce your risk of developing blood clots and related complications.
