Iliac Vein Compression Syndrome

Medically reviewed by Drugs.com. Last updated on Apr 6, 2025.

Iliac vein compression syndrome (IVCS) is a condition that affects the blood flow in a vein near your pelvis. The vein gets compressed by another structure in your body such as an artery or vertebrae. This closes the vein and stops blood flow from your leg to your heart. IVCS is also known as May-Thurner syndrome.
