ulcer is a type of wound that develops on the skin. A
venous skin ulcer is a shallow wound that occurs when
the leg veins don't return blood back toward the heart the way they should. This is called venous insufficiency. See a picture
of abnormal blood flow caused by venous insufficiency.
usually form on the sides of the lower leg, above the ankle and below the
calf. See a picture of
areas affected by venous skin ulcers.
Venous skin ulcers are slow
to heal and often come back if you don't take steps to prevent them.
A venous skin ulcer is also called a stasis leg ulcer.
Venous skin ulcers are caused by poor
blood circulation from the legs, such as from venous insufficiency. Your veins have
one-way valves that keep blood flowing toward the heart. In venous
insufficiency, the valves are damaged, and blood backs up and pools in the
vein. Fluid may leak out of the vein and into the surrounding tissue. This
can lead to a breakdown of the tissue and an ulcer.
Veins that become blocked also may cause fluid to pool, leading to

will diagnose venous skin ulcers by asking questions about your health and
looking at your legs. Your doctor may also use
duplex Doppler ultrasound to find out what is causing the ulcer. This test shows how well
blood is moving through the lower leg.
Your doctor may use other
tests to check for problems related to venous skin ulcers or to recheck the
ulcer if it does not heal within a few weeks after the start of treatment.
