Venous Insufficiency

venosVenous insufficiency is a condition where the flow of blood through the veins is inadequate, causing blood to pool in the legs. It can be caused by several different vein disorders, but it’s most often caused by either blood clots or varicose veins.

Chronic venous insufficiency can cause edema, pain, skin changes (discoloration, hardening, fibrosis, skin breakdown), and the development of venous stasis ulcers. The cornerstone of treatment for chronic venous insufficiency is external compression. External compression works in two ways: by reducing the edema that is preventing oxygen and nutrients from reaching the tissue; and by applying external pressure to the veins to improve circulation.

Sequential compression devices can be especially helpful for treating chronic venous insufficiency and healing venous stasis ulcers. The active compression reduces edema by stimulating lymphatic uptake, either locally or by moving the edema proximally for uptake in areas with healthy lymphatic. Reducing the edema increases oxygenation and promotes healing of chronic venous stasis ulcers. Removing the stagnant edema allows for better nourishment and oxygenation of the tissues, and reduces swelling at the wound edges, helping them to dose.

Venous insufficiency is a very common condition resulting from decreased blood flow from the leg veins up to the heart, with pooling of blood in the veins. Normally, one-way valves in veins keep blood flowing toward the heart—against the force of gravity.
