Our team

IVIS MED is devoted to the treatment of circulatory diseases focused on iliac vein disorders.

This has allowed us to discover the origin of hemorrhoids: a venous insufficiency due to a common iliac vein narrowing, diagnosed by an IVUS (Intravascular Ultrasound) procedure and healed by stenting it.

The development of our treatment started in 2013 when we began to work with IVUS. Since then we have increased its applications and summarized them in what we call IVIS (Iliac Vein Insufficiency Syndrome). Now IVIS diagnosis and treatment is our focus.

Who leads our team?
