Varicose Veins & Treatments
By Vascular Surgery
Veins are blood vessels that carry blood back to the heart. To keep blood moving toward the heart, veins have one way valves. When the valves breakdown, blood does not flow well and can cause Chronic Venous Insufficiency (CVI) and varicose veins. The abnormal flow of blood is typically referred to as ‘reflux’ since the blood moves backwards and forwards. Venous reflux occurs most often in veins closest to the skin (superficial veins) and varicose veins can be blue, red, or flesh-colored. They typically look like cords under the skin and can be twisted or bulging. Spider veins are like varicose veins, but much smaller. The look like small tree branches on the surface of the skin.
