Venous ulcer

Venous Ulcers

Venous ulcers, often referred to as leg ulcers, are chronic wounds that typically occur on the legs due to malfunctioning venous valves. They represent a significant portion of chronic wound cases and pose a challenge in healthcare due to their persistence and impact on quality of life.

Venous ulcer on the leg

Overview

Venous ulcers are primarily caused by venous insufficiency, a condition where the blood flow through the veins of the legs is inadequate, leading to increased pressure and skin changes.

Pathophysiology

• The improper functioning of venous valves in the legs causes blood to pool instead of returning to the heart.
• This results in increased pressure in the veins, leading to damage and ulcer formation, mostly along the medial distal leg.

Prevalence

• Venous ulcers account for 70% to 90% of leg ulcer cases.
• They are more common in older adults, and risk factors include deep vein thrombosis, obesity, and previous leg injuries.

Symptoms and Diagnosis

Patients with venous ulcers typically experience:

• Pain and discomfort in the affected area.
• Swelling and heaviness in the legs.
• Skin discoloration and eczema.

Diagnosis is usually based on medical history, physical examination, and sometimes doppler ultrasonography.

Treatment and Management

The management of venous ulcers includes:

• Compression therapy to improve venous blood flow.
• Wound care and dressing to promote healing.
• Elevating the legs to reduce swelling.
• In severe cases, surgery may be required to address underlying venous insufficiency.

Impact on Quality of Life

• Venous ulcers can significantly impact the quality of life due to pain and mobility issues.
• They often require long-term care and can recur if underlying conditions are not managed.
