Venous Stasis Ulcers: Why They Develop, Why They Won't Heal, and How Treating Vein Disease Can Change Everything

Venous stasis ulcers are one of the most serious complications of chronic venous insufficiency (CVI), yet they are frequently misunderstood and undertreated. Many people spend months—or even years—treating the wound itself without addressing the underlying reason it developed in the first place.

At Sheen Vein & Aesthetics in St. Louis, we believe that successful treatment begins by identifying and correcting the underlying vein disease that causes these wounds. While proper wound care is important, ulcers often continue to recur unless the abnormal venous circulation is treated.

If you or someone you love has a wound on the lower leg that simply refuses to heal, understanding venous stasis ulcers may be the first step toward finally finding a lasting solution.

What Is a Venous Stasis Ulcer?

A venous stasis ulcer is an open wound that develops because blood cannot efficiently return from the legs back to the heart. Instead of flowing upward, blood pools within the veins due to damaged vein valves. This creates persistently elevated venous pressure, known as venous hypertension, which gradually damages the surrounding skin and soft tissues.

Over time, this pressure decreases oxygen delivery to the skin, increases inflammation, and impairs normal tissue healing. Eventually, even a small scratch, insect bite, or minor trauma may progress into a chronic ulcer.

Venous stasis ulcers account for approximately 70–80% of all chronic leg ulcers, making them the most common chronic wound affecting the lower extremities.

How Healthy Veins Normally Work

Healthy leg veins contain one-way valves that keep blood moving upward toward the heart.

Every time you walk:

Your calf muscles squeeze the veins.
Blood is pumped upward.
Vein valves prevent blood from falling backward.

This process is often called the "calf muscle pump."

When these valves become damaged, gravity causes blood to leak backward (venous reflux). Instead of circulating normally, blood remains trapped in the lower legs.

The longer this continues, the higher the pressure becomes inside the veins.

Eventually this damages:

Small blood vessels
Skin
Fat beneath the skin
Lymphatic drainage
Local immune function

This is why venous disease is much more than a cosmetic issue.

What Causes Venous Stasis Ulcers?

Venous ulcers usually develop after years of untreated chronic venous insufficiency.

Common risk factors include:

Varicose veins
Previous blood clots (DVT)
Family history of vein disease
Obesity
Pregnancy
Standing occupations
Aging
Previous leg injury
Limited mobility
Smoking
Lymphedema

Many patients have experienced swollen legs for years before their first ulcer appears.

Signs That an Ulcer Is Caused by Vein Disease

Venous ulcers typically develop:

Around the inside of the ankle
Just above the ankle bone
Occasionally on the lower calf

They often have:

Irregular borders
Shallow depth
Drainage
Yellow tissue within the wound
Surrounding brown skin discoloration
Thickened skin
Swelling
Aching or heaviness

Patients frequently notice their legs become more swollen as the day progresses.

Skin Changes That Often Occur Before an Ulcer Forms

Most venous ulcers don't appear suddenly.

Years before the wound develops, patients often experience:

Leg Swelling

Fluid leaks into surrounding tissues because of elevated venous pressure.

Brown Skin Discoloration

Iron from red blood cells leaks into the skin.

This creates the classic rusty-brown staining called hemosiderin deposition.

Thickened Skin

Chronic inflammation causes the skin to become:

Hard
Tight
Fibrotic

This condition is known as lipodermatosclerosis.

Itching

Many patients develop severe itching due to venous eczema.

Repeated scratching may eventually trigger skin breakdown.

White Scar-Like Areas

These pale patches (atrophie blanche) indicate severely impaired blood flow and carry a higher risk of ulcer formation.

Why Won't My Leg Wound Heal?

This is one of the most common questions we hear.

Many patients receive:

Antibiotics
Dressings
Ointments
Compression wraps

Yet the ulcer keeps returning.

The reason is simple.

These treatments help manage the wound but do not eliminate the high venous pressure causing ongoing tissue damage.

Imagine trying to repair a leaking ceiling without fixing the broken pipe above it.

Until the abnormal veins are treated, healing may remain slow or incomplete.

Are Venous Ulcers Dangerous?

Yes.

Without treatment they may lead to:

Serious infections
Cellulitis
Bone infection (osteomyelitis)
Hospitalization
Chronic pain
Reduced mobility
Social isolation
Permanent skin damage

Large ulcers may remain open for years.

Some patients become unable to work because of persistent drainage and discomfort.

How Are Venous Stasis Ulcers Diagnosed?

Diagnosis begins with a thorough medical history and physical examination.

However, the most important test is a venous duplex ultrasound.

This painless examination evaluates:

Vein valve function
Venous reflux
Blood clots
Deep veins
Superficial veins
Perforator veins

Without ultrasound, the true cause of the ulcer may be missed.

The Importance of Compression Therapy

Compression stockings or multilayer compression wraps remain one of the cornerstones of venous ulcer treatment.

Compression works by:

Reducing swelling
Improving blood flow
Lowering venous pressure
Supporting wound healing

However, compression alone does not permanently correct damaged veins.

Many patients experience recurrent ulcers if underlying venous reflux is left untreated.

Modern Treatment Options for Venous Disease

Fortunately, treatment has advanced tremendously over the past two decades.

Most patients no longer require surgical vein stripping.

Instead, minimally invasive office-based procedures can close diseased veins with little downtime.

These include:

Endovenous Laser Therapy (EVLT)

Laser energy seals the abnormal vein from the inside.

Blood naturally reroutes into healthier veins.

Ultrasound-Guided Foam Sclerotherapy

A specialized medication is injected into abnormal veins under ultrasound guidance.

This is particularly useful for tributary veins and recurrent disease.

Visual Sclerotherapy

Small residual varicose and spider veins can often be treated with injection therapy after larger refluxing veins have been corrected.

Individualized Treatment Plans

Every patient's anatomy is unique.

Treatment should be customized using ultrasound findings rather than applying a one-size-fits-all approach.

How Treating Vein Disease Improves Healing

Numerous studies have shown that correcting venous reflux can:

Accelerate ulcer healing
Reduce recurrence
Improve quality of life
Decrease chronic pain
Reduce swelling
Lower long-term healthcare costs

Patients often notice improvements in heaviness, aching, and fatigue even before complete wound healing occurs.

What Can Patients Do at Home?

While medical treatment is important, patients also play a major role in recovery.

Helpful measures include:

Wear compression as directed.
Walk regularly to activate the calf muscle pump.
Elevate your legs several times daily.
Maintain a healthy weight.
Stay physically active.
Moisturize dry skin.
Avoid prolonged standing or sitting.
Control diabetes if present.
Stop smoking.

These lifestyle changes help improve circulation and reduce recurrence.

Can Venous Ulcers Come Back?

Unfortunately, yes.

Without treating the underlying venous insufficiency, recurrence rates remain high.

Even after successful healing, continued management may include:

Compression stockings
Regular walking
Periodic follow-up
Monitoring for recurrent reflux

Preventing another ulcer is much easier than treating a new one.

When Should You See a Vein Specialist?

You should seek evaluation if you have:

A wound near the ankle lasting more than two weeks
Chronic leg swelling
Brown skin discoloration
Varicose veins
Heavy or aching legs
Recurrent cellulitis
A previous venous ulcer
Skin thickening around the ankles

Early treatment may prevent an ulcer from ever developing.

Frequently Asked Questions

Can antibiotics heal a venous ulcer?

Only if an infection is present. Most venous ulcers are caused by poor circulation rather than infection. Treating the underlying vein disease is often necessary for lasting healing.

Are venous ulcers painful?

Many patients experience aching, burning, or throbbing discomfort, although some ulcers are surprisingly painless. Pain often worsens with prolonged standing and improves when the leg is elevated.

Will compression stockings heal the ulcer by themselves?

Compression is essential because it reduces swelling and venous pressure, but many patients also require treatment of the refluxing veins to achieve faster healing and reduce the risk of recurrence.

How long do venous ulcers take to heal?

Healing time varies depending on the size of the ulcer, the severity of venous insufficiency, overall health, and whether the underlying vein disease is treated. Some ulcers heal within weeks, while others can persist for months or even years if the cause is not addressed.

Can minimally invasive vein procedures be performed if I already have an ulcer?

Yes. In many cases, treating the underlying venous reflux with procedures such as endovenous laser therapy or ultrasound-guided foam sclerotherapy can improve healing rates and reduce the likelihood of future ulcers. Your treatment plan should be individualized after a comprehensive venous ultrasound evaluation.
