Venous Stasis Dermatitis Symptoms and Treatment
Venous stasis dermatitis, also known as stasis eczema or gravitational dermatitis, is a chronic inflammatory skin condition that typically affects the lower extremities. This condition arises due to chronic venous insufficiency (CVI), where the veins in the legs cannot efficiently return blood to the heart, leading to a buildup of pressure and subsequent skin changes.

Get A Second OpinionSymptoms of Venous Stasis Dermatitis
The symptoms of venous stasis dermatitis can vary in intensity and presentation, but they generally include:
- Swelling (Edema): Persistent swelling of the lower legs and ankles, which may worsen throughout the day.
- Itching and Discomfort: Affected areas often become itchy, leading to scratching, which can exacerbate the condition.
- Redness and Scaling: The skin may appear reddish or brownish and can develop a scaly texture.
- Weeping and Crusting: Severe cases might involve oozing of clear fluid and the formation of crusts on the skin.
- Ulceration: In advanced stages, venous stasis dermatitis can lead to the formation of painful ulcers, particularly around the ankles.
Understanding these symptoms is crucial for early diagnosis and effective management of the condition.
Causes of Venous Stasis Dermatitis
The primary cause of venous stasis dermatitis is chronic venous insufficiency (CVI), which results from malfunctioning valves in the veins of the lower extremities. This malfunction causes blood to pool in the legs, increasing venous pressure and leading to inflammation and skin changes.
Pathophysiology of Venous Stasis Dermatitis
The pathophysiology of venous stasis dermatitis involves several interconnected processes:
- Venous Hypertension: Faulty venous valves lead to increased pressure within the veins.
- Capillary Leakage: Elevated pressure causes capillaries to leak fluid and proteins into surrounding tissues.
- Inflammation: The leaked substances trigger an inflammatory response, contributing to skin changes and damage.
- Fibrosis: Chronic inflammation results in tissue fibrosis, further impairing circulation and exacerbating symptoms.
Understanding these mechanisms helps in comprehending the progression and severity of venous stasis dermatitis.
Risk Factors for Venous Stasis Dermatitis
Several factors increase the risk of developing venous stasis dermatitis, including:
- Age: The condition is more common in older adults due to age-related changes in blood vessels.
- Gender: Women are more likely to develop venous stasis dermatitis than men.
- Obesity: Excess body weight places additional pressure on the veins, exacerbating CVI.
- Sedentary Lifestyle: Prolonged periods of inactivity can impair venous return.
- Pregnancy: Hormonal changes and increased blood volume during pregnancy can contribute to CVI.
- History of Deep Vein Thrombosis (DVT): Previous DVT episodes can damage venous valves, leading to CVI.
Recognizing these risk factors is essential for prevention and early intervention.
Diagnosis of Venous Stasis Dermatitis
Diagnosing venous stasis dermatitis involves a combination of clinical evaluation and diagnostic tests. Healthcare providers typically perform the following:
Clinical Examination
A thorough physical examination is conducted to assess the appearance and characteristics of the affected skin, including swelling, redness, scaling, and ulceration.
Doppler Ultrasound
A Doppler ultrasound is often used to evaluate blood flow in the veins and identify any underlying venous insufficiency or blockages.
Skin Biopsy
In certain cases, a skin biopsy may be performed to rule out other skin conditions and confirm the diagnosis of venous stasis dermatitis.
ICD-10 Coding
For accurate medical documentation, venous stasis dermatitis of both lower extremities is classified under the ICD-10 code I87.2.

Book an AppointmentTreatment Options for Venous Stasis Dermatitis
Effective management of venous stasis dermatitis requires a multifaceted approach, including lifestyle modifications, medical treatments, and, in severe cases, surgical interventions.
Lifestyle Modifications
- Compression Therapy: Wearing compression stockings helps improve venous return and reduce swelling.
- Leg Elevation: Elevating the legs above heart level several times a day can alleviate symptoms.
- Physical Activity: Regular exercise promotes circulation and strengthens leg muscles.
Medical Treatments
- Topical Corticosteroids: These are prescribed to reduce inflammation and itching.
- Moisturizers: Keeping the skin well-hydrated helps prevent dryness and scaling.
- Antibiotics: In cases of secondary infection, antibiotics may be necessary.
Advanced Treatments
- Sclerotherapy: This procedure involves injecting a solution into affected veins to close them off and improve circulation.
- Laser Therapy: Laser treatments target and close off damaged veins.
- Venous Surgery: In severe cases, surgical interventions like vein stripping or endovenous laser therapy (EVLT) may be required.
Wound Care for Ulcers
For patients with venous ulcers, specialized wound care is essential. This may involve debridement, dressings, and advanced therapies like negative pressure wound therapy (NPWT).
