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.

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

FeaturePrimary LymphedemaPhlebolymphedema
CauseCongenital lymphatic dysfunctionVenous disease leading to lymphatic failure
OnsetChildhood, adolescence, or adulthoodUsually later adulthood
LocationOften unilateralFrequently bilateral
Skin DiscolorationLess common earlyCommon
Venous DiseaseUsually absentPresent
Venous UlcersRareCommon

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.


The four pillars of Complete Decongestive Therapy: MLD, Compression Bandaging, Exercise, and Skin Care.

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:

Role of Compression Therapy in Lymphedema
  • 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.
