Venous ulcers (VU), also known as stasis ulcers or varicose ulcers, are a prevalent form of chronic wound. These ulcers primarily develop due to the improper functioning of venous valves in the legs, leading to venous insufficiency. This condition significantly contributes to chronic wound cases, accounting for 70% to 90% of such incidences. Understanding venous ulcers’ causes, symptoms, and treatments is crucial for managing this debilitating condition effectively.
Causes and Pathophysiology Venous ulcers arise when the veins in the legs fail to circulate blood back to the heart efficiently. This inefficiency, known as venous insufficiency, causes blood to pool in the veins, increasing venous pressure. The high pressure and accumulation of blood lead to damage and ulceration of the surrounding tissues. Several factors contribute to the development of venous insufficiency, including:
- Age: Aging veins lose elasticity, making it difficult for blood to flow efficiently.
- Genetics: A family history of varicose veins or deep vein thrombosis can increase the risk.
- Obesity: Excess body weight adds pressure on the veins, impairing blood flow.
- Prolonged Standing or Sitting: Occupations requiring long periods of standing or sitting can impede blood circulation.
- Previous Leg Injuries or Surgeries: These can damage veins and impair their function.
Symptoms and Identification Venous ulcers typically develop along the medial distal leg, particularly around the ankles. These ulcers are often painful and can significantly impact the quality of life. Common symptoms include:
- Skin Changes: The skin around the ulcer may appear reddish-brown or purplish due to hemosiderin deposition, resulting from red blood cell breakdown.
- Swelling: Persistent swelling, known as edema, is common in the affected leg.
- Itching and Discomfort: The skin may feel itchy, tight, and uncomfortable.
- Discharge: Ulcers may exude clear fluid or pus, indicating infection.
- Pain: The ulcer can be very painful, especially if infected or inflamed.
Early identification of these symptoms is crucial for timely intervention and preventing complications.
Treatment Approaches Managing venous ulcers involves addressing the underlying venous insufficiency and promoting ulcer healing. Treatment strategies include:
- Compression Therapy: Compression stockings or bandages are the cornerstone of venous ulcer treatment. They help reduce venous pressure, improve blood flow, and decrease swelling.
- Wound Care: Regular cleaning and dressing of the ulcer are essential to prevent infection and promote healing. Advanced wound dressings, such as hydrocolloids, foams, and alginates, can aid in moisture balance and protection.
- Medications: Antibiotics may be prescribed if there is an infection. Topical or systemic medications to manage pain and inflammation might also be necessary.
- Surgical Interventions: In severe cases, surgical procedures like vein stripping, ligation, or endovenous laser therapy may be considered to correct venous insufficiency.
- Lifestyle Modifications: Patients are encouraged to maintain a healthy weight, exercise regularly, and avoid prolonged periods of standing or sitting to improve circulation.

Prevention and Long-term Management Preventing venous ulcers involves addressing risk factors and adopting healthy lifestyle practices. Regular exercise, leg elevation, and wearing compression stockings can prevent venous stasis and reduce ulcer recurrence. Additionally, managing chronic conditions such as diabetes and hypertension is vital for overall vascular health.
Conclusion Venous ulcers are a significant health concern, affecting a large portion of individuals with chronic wounds. Understanding their causes, symptoms, and treatment options is essential for effective management and improving patients’ quality of life. Early intervention, combined with comprehensive care strategies, can significantly enhance healing outcomes and prevent complications. If you suspect you have a venous ulcer, seeking medical advice promptly is crucial for proper diagnosis and treatment.
