Stasis Dermatitis

Stasis dermatitis can result when there are circulatory problems (insufficient venous return) in the lower extremities. The condition is present in about 6% of the US population over 50 years of age. Women seem to be at slightly higher risk. The condition is usually chronic.

Symptoms

Initial symptoms usually include skin reddening and mild scaling on the lower legs (below the knee) and ankles, although it can also occur on the lower arms and wrists as well. Then, over a period of weeks or months, the skin slowly darkens while the affected areas may become itchy and swollen (edema). As the skin thins and weakens, it takes on a shiny appearance while ulcers may develop. Secondary infections (from bacteria) may develop in the open sores.

Causes

The cause of this skin disease can be directly attributed to poor circulation in the legs and ankles. Insufficient venous return can lead to capillary leakage and the associated symptoms listed above. The presence of varicose veins can be a contributing factor in this skin disease. Other contributing factors can include congestive heart failure, and conditions that cause arm, leg, foot and ankle swelling.

Treatment

Prevention measures to reduce the incidence of swelling associated with blood pooling are most effective (i.e. keeping the legs raised above the heart while sitting). Prescription compression stockings may also help. Diuretics may be prescribed to help reduce the build-up of excess fluids. On occasion, Sequential Gradient Pump Therapy may be prescribed to help reduce the build-up of fluids in the lower legs.

To help reduce skin irritations and inflammation, topical corticosteroids may be prescribed. If infection develops in the ulcerated areas, oral and/or topical antibiotics are usually prescribed.
