When a patient presents with chronic lower-extremity swelling, many healthcare providers immediately think of either venous insufficiency or lymphedema. However, a growing number of patients are actually experiencing a combination of both conditions—a disorder known as phlebolymphedema.
Despite its prevalence, phlebolymphedema remains underdiagnosed and frequently misunderstood. Many patients spend years treating venous disease alone while underlying lymphatic dysfunction continues to worsen. Others are referred for lymphedema therapy without recognition of the venous component driving their swelling.
For Certified Lymphedema Therapists (CLTs), vascular specialists, wound care clinicians, physical therapists, occupational therapists, and other healthcare professionals, understanding phlebolymphedema is becoming increasingly important.
As rates of obesity, chronic venous disease, and lower-extremity edema continue to rise, therapists who can accurately identify and treat phlebolymphedema are uniquely positioned to improve patient outcomes and quality of life.
What Is Phlebolymphedema?
Phlebolymphedema is a condition that occurs when chronic venous insufficiency (CVI) overwhelms and eventually damages the lymphatic system.

The term combines:
- Phlebo- (veins)
- Lymphedema (lymphatic dysfunction)
In simple terms, venous disease creates excessive fluid in the tissues. Over time, the lymphatic system is forced to work harder to remove that fluid.
Eventually, the lymphatic system can no longer keep up.
When this occurs, both the venous and lymphatic systems become impaired, resulting in persistent swelling that often becomes chronic and progressive.
Understanding the Relationship Between Veins and Lymphatics
The circulatory and lymphatic systems work closely together.
Healthy veins return blood to the heart.

Healthy lymphatic vessels collect excess fluid, proteins, and cellular waste from tissues and return them to circulation.
When venous valves become damaged, blood begins to pool in the lower extremities.
This leads to:
- Increased venous pressure
- Fluid leakage into surrounding tissues
- Chronic inflammation
- Tissue damage
Initially, the lymphatic system compensates for this extra fluid burden.
Over time, however, prolonged overload can damage lymphatic vessels and lymph nodes.
This transition marks the development of phlebolymphedema.
Why Phlebolymphedema Is Becoming More Common
Several healthcare trends are contributing to rising rates of phlebolymphedema.
Aging Population
As people age, venous valve function naturally declines.
Chronic venous insufficiency becomes increasingly common among older adults.
Obesity
Obesity places additional pressure on both venous and lymphatic systems.
Research has shown obesity to be a major risk factor for:
- Venous disease
- Lymphedema
- Chronic edema
- Phlebolymphedema
Sedentary Lifestyles
Limited physical activity reduces calf-muscle pump efficiency, impairing both venous return and lymphatic transport.
Chronic Health Conditions
Patients with:
- Heart disease
- Diabetes
- Reduced mobility
- Vascular disease
often face increased risk of developing combined venous and lymphatic dysfunction.
Signs and Symptoms of Phlebolymphedema
One reason phlebolymphedema is often missed is that its symptoms overlap with both venous insufficiency and lymphedema.
Common signs include:
Persistent Lower-Leg Swelling
Swelling typically begins around the ankles and lower legs but may progress upward over time.
Heaviness and Fatigue
Patients often describe:
- Aching legs
- Fatigue
- Tightness
- Difficulty standing for long periods
Skin Changes
Chronic inflammation can lead to:
- Hyperpigmentation
- Fibrosis
- Thickened skin
- Hemosiderin staining

Stemmer’s Sign
As lymphatic dysfunction progresses, a positive Stemmer’s Sign may become present.
This is often a clue that lymphatic involvement has developed.
Read more about Stemmer’s Sign and it’s connection to lymphedema.
Recurrent Cellulitis
Patients may experience repeated skin infections due to impaired immune function and chronic swelling.
Venous Ulcers
Non-healing wounds near the ankles are common in advanced cases.
How Phlebolymphedema Differs From Primary Lymphedema
| Feature | Primary Lymphedema | Phlebolymphedema |
|---|---|---|
| Cause | Congenital lymphatic dysfunction | Venous disease leading to lymphatic failure |
| Onset | Childhood, adolescence, or adulthood | Usually later adulthood |
| Location | Often unilateral | Frequently bilateral |
| Skin Discoloration | Less common early | Common |
| Venous Disease | Usually absent | Present |
| Venous Ulcers | Rare | Common |
Understanding these differences is critical for accurate diagnosis and treatment planning.
Diagnosing Phlebolymphedema
No single test confirms phlebolymphedema.
Diagnosis typically involves a comprehensive assessment.
Patient History
Therapists should ask about:
- Previous DVT
- Varicose veins
- Leg ulcers
- Chronic swelling
- Family history
- Mobility limitations
Physical Examination
Evaluate:
- Limb shape
- Skin changes
- Fibrosis
- Pitting edema
- Stemmer’s Sign
Venous Testing
Duplex ultrasound is commonly used to identify venous reflux and valve dysfunction.

Lymphatic Assessment
Therapists may assess:
- Tissue texture
- Limb volume
- Circumferential measurements
- Response to compression
In some cases, advanced imaging such as lymphoscintigraphy may be utilized.
Why Early Identification Matters
Untreated phlebolymphedema can lead to significant complications.
These include:
- Progressive swelling
- Reduced mobility
- Chronic pain
- Recurrent cellulitis
- Venous ulceration
- Increased healthcare utilization
Early intervention can slow disease progression and improve long-term outcomes.
Treatment Strategies for Phlebolymphedema
Successful treatment requires addressing both the venous and lymphatic components.
This is where many treatment plans fall short.
Treating only the veins often leaves patients with persistent swelling.
Treating only the lymphatics ignores the underlying cause.
The most successful approach is comprehensive management.

Complete Decongestive Therapy (CDT)
CDT remains the gold standard conservative treatment.
Components include:
Manual Lymphatic Drainage (MLD)
Gentle manual techniques stimulate lymphatic flow and redirect fluid to healthy drainage pathways.
Compression Therapy

Compression is critical for:
- Reducing edema
- Supporting venous return
- Improving lymphatic transport
Patients may benefit from:
- Compression stockings
- Adjustable wraps
- Multi-layer bandaging
Exercise
Movement activates the muscle pump system.
Recommended activities include:
- Walking
- Aquatic exercise
- Therapeutic exercise programs

Skin Care
Meticulous skin care reduces infection risk and supports tissue health.

The Role of Compression Therapy
Compression is often the cornerstone of phlebolymphedema management.
Benefits include:

- Improved venous return
- Reduced edema
- Better lymphatic uptake
- Enhanced wound healing
Therapists should ensure garments are:
- Properly fitted
- Reassessed regularly
- Appropriate for patient mobility and lifestyle
Phlebolymphedema and Wound Care
Many patients with phlebolymphedema develop venous leg ulcers.
These wounds can be difficult to heal because:
- Edema impairs oxygen delivery
- Inflammation damages tissues
- Lymphatic dysfunction delays healing

Collaboration between:
- CLTs
- Wound care specialists
- Vascular physicians
often produces the best outcomes.
Why Therapist Education Is More Important Than Ever
As chronic edema becomes increasingly common, therapists must understand the complex relationship between vascular and lymphatic disease.
Many healthcare providers receive limited formal education regarding:
- Lymphatic anatomy
- Edema differentiation
- Compression therapy
- CDT
Advanced training can dramatically improve clinical outcomes and confidence.
