Venous Leg Ulcers: Causes and Modern Treatments

Learn how venous insufficiency causes leg ulcers and discover effective treatments including compression therapy and vein procedures.

Venous leg ulcers account for 70-80% of all leg ulcers. They develop when faulty vein valves cause blood to pool in the legs, leading to skin breakdown. With proper treatment, most venous ulcers can heal—but addressing the underlying vein problem is key to preventing recurrence.

How Venous Ulcers Develop

1
Valve Failure: Vein valves weaken and don't close properly
2
Blood Pooling: Blood flows backward and pools in the lower legs
3
Pressure Buildup: Increased pressure damages small blood vessels
4
Skin Breakdown: Skin becomes fragile and ulcerates

Recognizing Venous Ulcers

Location

Usually on the inner ankle or lower leg, rarely on the foot

Appearance

Shallow with irregular borders, often with a red wound bed

Skin Changes

Surrounding skin may be discolored, thickened, or scaly

Symptoms

Aching, heaviness that improves with elevation

Treatment Approach

Compression Therapy

The cornerstone of treatment. Compression stockings or wraps help push blood back to the heart and reduce swelling. Healing rates improve dramatically with proper compression.

Treating the Veins

Procedures like endovenous ablation can close faulty veins, reducing pressure and preventing recurrence. Many ulcers won't stay healed without addressing the underlying vein problem.

Wound Care

Regular debridement, appropriate dressings, and infection control help the wound heal while compression addresses the cause.

Preventing Recurrence

Up to 70% of venous ulcers recur within 5 years without proper prevention:

  • Wear compression stockings daily for life
  • Elevate legs when sitting
  • Stay active—walking helps pump blood back to the heart
  • Consider vein procedures to fix the underlying problem
