Endovascular treatment of iliac vein compression syndrome (May-Thurner).

May-Thurner syndrome is a rare condition that results from narrowing of the left common iliac vein (CIV) lumen due to pulsatile compression from the right common iliac artery (CIA) as it crosses anterior to it. We present a case of 24-years old female with left lower limb deep venous thrombosis (DVT). Duplex ultrasonography revealed extensive left-sided DVT. Magnetic resonance venogram suggested DVT with left CIV being compressed by right CIA. Pharmaco-mechanical catheter directed thrombolysis-thrombectomy followed by left iliac vein stent placement restored patency to the venous system, with resolution of symptoms.
