May-Thurner Syndrome Clinical Trial
— USvsCTVOfficial title:
Color Doppler U/S vs MSCT Venography in the Diagnosis of May-Thurner Syndrome
May-Thurner syndrome is the result of compression of the left common iliac vein between the
right common iliac artery and overlying vertebrae.
In This Study , We will detect the role of color doppler US in the diagnosis of May-Thurner
Syndrome in comparison to Direct CT Venography

Inclusion Criteria: - advanced chronic venous insufficiency submitted to clinical treatment for at least 1 year with no response. - Subject must be > 18 and < 80 years of age. - informed consent document before the planned procedure. - On duplex ultrasound: patent common femoral vein, and patent deep femoral vein, and/or femoral vein of the study leg.
