Venous Stasis Dermatitis and Venous Ulcerations

Stasis dermatitis (also called venous stasis dermatitis) is an inflammatory reaction seen in the skin of the lower leg caused by static (slow or delayed) venous flow of the leg. Stasis dermatitis is common in patients 50 years and older. Left untreated, venous stasis can progress to a venous ulceration. The most common location for a venous ulceration of the lower extremity is over the medial aspect of the ankle.  Venous ulcerations vary in size and depth. Stasis dermatitis and venous ulcerations are more common in women than men.


  • Redness, dryness and peeling of the distal 1/3 to 1/2 of the lower leg
  • Firm swelling of the distal leg
  • Pitting edema of the foot and leg
  • Ulceration of the medial ankle

The symptoms of stasis dermatitis vary with the general health of the patient, duration of the condition and status of treatment. Early stasis dermatitis shows a red blush surrounding the lower 1/3 of the leg. Stasis dermatitis is usually found in both legs with a symmetrical presentation. Pigmentation changes (darkening) of the leg usually follows a prolonged period of swelling (edema) of the lower leg.


stasis_dermatitis_legVenous stasis describes the slowing of venous blood flow as blood returns from the foot to the heart.  This slowing is causes by incompetant veins.  The inability of blood to flow effectively up the leg result in chronic swelling of the lower leg (venous hypertension) and a visible change in the stasis_dermatitisskin called venous stasis dermatitis.  As the duration of edema continues, stasis dermatitis will worsen with eczematization of the leg. Eczematization is the thickening of the skin with lichenification. Lichenification describes crusting and layering of the skin that occurs when the normal exfoliative properties of the skin are disrupted by chronic swelling. In this stage of stasis dermatitis, oozing, scaling and deep pigmentation changes in the skin may become apparent. The skin and deeper tissues of the lower leg will also become indurated (firm).

If left untreated, stasis dermatitis will continue to the final stage where the skin ulcerates due to the back pressure caused by venous incompentency. In this stage, the leg will open and weep fluid. Infection may also become a secondary issue due to a breach in the skin.veins_of_the_legveins_of_the_leg

The function of the venous system of the leg is to return blood from the foot back to the heart.  The lower extremity venous system consists of three types of veins; superficial, perforator and deep veins.  Veins are very similar to arteries with the exception that veins have less muscle and must subsequently carry a lower intra-luminal pressure.  Superficial and deep veins contain valves that open with blood flow to the heart and close with a reversal of flow.  The purpose of the valves is to insure unidirectional flow of blood to the heart.  The veins of the leg are unique in that they also use muscular contraction of the lower leg to drive blood to the heart.  This pump is called the calf pump.  While walking, compression of the vein by the muscle helps to facilitate blood flow to the heart.

The two primary superficial veins of the leg are the great saphenous and the small saphenous veins.  While standing, the pressure in each of these veins is equal to the pressure that would be found in a column of blood extending from the foot to the heart.  When the calf pump is activated, blood is pumped proximally through the perforator veins into the deep veins.  The deep veins of the leg include the posterior tibial vein, anterior tibial vein, popliteal vein and femoral vein.

Causes and contributing factors

Factors that can contribute to the early onset of stasis dermatitis include obesity, inactivity, venous injury, dependency (lower than the heart) of the leg and infection of the leg. The primary contributing cause of stasis dermatitis is valvular incompentency of the veins of the leg resulting in chronic edema (swelling).

Differential diagnosis

The differential diagnosis for venous stasis includes;

Peripheral arterial disease
Varicose veins


Central to the treatment of venous stasis dermatitis and venous stasis ulcers is control of lower extremity edema due to venous hypertension. Edema can be controlled by elevating the legs above the level of the heart, use ofvenous ulceration diuretics and the use of compression hose. It's important to realize that when using compression hose, the hose need to be put on first thing in the morning in advance of any swelling. If swelling is allowed to occur before applying the support hose, that swelling will likely be there the rest of the day.  Additional tools used to manage peripheral edema include edema pumps, compression dressings and a Circ-Aid.

Eczematous changes (peeling and flaking) and lichenification (hardening of the epidermis) can be treated with skin softening agents. Inflammatory changes of the skin are common and can be treated with topical or oral steroids. Discoloration of the skin is difficult to treat. Discoloration or darkening of the skin is often due to the deposition of hemosiderin (the iron component of red blood cells). Once hemosiderin venous_stasis_ulceris deposited in the skin, is is much like a tattoo that stains the skin from within.

Ulceration of the skin is common, particularly at the medial (inside) ankle. The area superficial to the origin of the great saphenous vein is the most common site of ulceration. Ulcerations should be cultured and treated for infection if necessary. Compression boots are the gold standard for treating venous stasis ulcerations. Compression boots can be made from a number of materials but the primary role of the compression boot is to manage peripheral edema.  Compression boots are changed on a weekly basis.  Treatment can take from one to many weeks to see complete closure of the venous ulcer.  Negative pressure treatment of the wound along with skin grafting may be necessary in severe, non-healing ulcers.

Care of venous stasis ulcerations can be complex and are best managed by a team of specialists at a wound care center.  Advanced treatment modalities are difficult to manage in an office setting, therefore, wound care centers often become an important part of care with venous stasis ulcerations.

When to contact your doctor

Management of venous stasis and venous ulcerations should not be attempted at home.  Consult your podiatrist or local wound care center for additional treatment recommendations.
