Official Title: Prospective, Single-arm, Single Center, Pilot Study of Vascular Ultrasound Imaging Used as an Adjunct to Intravascular Ultrasound for Diagnosing Iliac Vein Obstruction

Brief Summary:

• Determine the sensitivity, specificity and accuracy of vascular ultrasound, using direct and indirect ultrasonographic signs, in the obstructive diseases of iliac venous segment, in patients with advanced chronic venous insufficiency (CEAP 3-6), considering the intravascular ultrasound (IVUS) as the gold standard for this diagnosis.
• Develop an algorithm for noninvasive ultrasound investigation of obstructive lesions in the iliac segment in patients with advanced chronic venous insufficiency (CEAP 3-6).
