Venous Stasis Ulcers

One of the most common causes of ulcers on the legs is venous stasis. The veins of the legs normally have valves that function to interrupt the pressure of gravity on the long column of blood from the heart to the lower legs in the upright position. In patients who have had blood clots in their leg veins or have had other causes of injury to the valves in the leg veins the pressure of blood against the vein walls, and onto the capillaries in the lower legs can be very high. This can lead to leakage of the blood cells and fluid out of the capillaries into the tissue of the legs, leading to chronic swelling and changes in the skin. With these skin changes comes poor healing and cracking of the skin, which often heals poorly leading to ulcers. These are called venous stasis ulcers, and can be very difficult to get to heal.

Prevention of stasis ulcers is really the key because once an ulcer develops it can be difficult to get to heal. You can prevent stasis ulcers by keeping the skin of the legs moist using a good emollient like Eucerin cream In addition avoid trauma to the legs if possible. Many times it is necessary to wear compression hose to keep the swelling controlled, and prevent further skin deterioration. Elevation of the legs is important, especially elevation above the level of the heart. To do this you can lie down and put your feet up on several pillows for 15-20 minutes two or three times a day.

PRESSURE ULCER

If you develop a stasis ulcer you should seek medical attention early. Waiting until the ulcer is large, deep or infected can make it even more difficult to treat. Many physicians treat stasis ulcers with a type of non-compression wrap called an Unna boot, which I find very helpful. Antibiotics are sometimes needed if infection is noted.

Take care of your legs if you have venous insufficiency and stasis, so you avoid ulcers, and if you get an ulcer, get medical attention early.
