Chronic venous insufficiency (CVI) is a condition that occurs when the venous wall and/or valves in the leg veins are not working effectively, making it difficult for blood to return to the heart from the legs.
Occurs when the veins in your legs are not working effectively and it becomes increasingly difficult for blood to pass through the vein walls or valves to flow back to your heart.
Spider veins (or telangiectasias) are groups of small, visible blood vessels that develop near the surface of the skin. Spider veins often have a blue or red coloring and may be accompanied by an itching, tingling, or throbbing feeling.
Varicose veins can be unsightly, but more importantly they can cause Chronic Venous Insufficiency (CVI). Here, the valves malfunction causing ankles and legs to swell. Long-standing varicose veins can lead to leg ulcers.
