1What Is Chronic Venous Insufficiency?
In general, oxygen-rich blood is transported to other parts of the body through the arteries, whereas the veins are responsible for carrying deoxygenated blood back. Venous insufficiency is a condition that causes difficulty in the transport of oxygen-depleted blood to the heart from the legs and arms. It typically occurs when valves in the veins are dilated or damaged, which makes them fail to shut properly. As a result, blood would flow backward to the veins rather than forward to your heart. If left untreated, the condition may become chronic and result in many serious complications that require medical attention. [1]
