Populations and Risk Factors
- Over 50% of people over age 50; prevalence increases with each decade
- Females 30–50 affected more than males (approximately 2:1 ratio) due to estrogen and progesterone effects on venous smooth muscle relaxation and valve function
- Pregnancy: uterine compression of the IVC increases venous pressure; hormonal effects relax venous walls; risk increases with each pregnancy
- Prolonged standing occupations (retail workers, healthcare workers, teachers, hairdressers): gravitational venous pooling exceeds valve capacity
- Obesity: increased intra-abdominal pressure impedes venous return
- Familial predisposition: genetic weakness of venous wall collagen and valve structure
- Sedentary lifestyle: loss of calf muscle pump ("soleus sump pump") contribution to venous return
- History of DVT: post-thrombotic syndrome damages venous valves and produces secondary varicosities
- Chronic constipation: repetitive straining increases intra-abdominal pressure
Causes and Pathophysiology
Normal Venous Return Mechanism
- Venous return from the lower extremities depends on three mechanisms: the calf muscle pump (soleus and gastrocnemius contraction compresses deep veins, propelling blood upward), one-way venous valves (prevent retrograde flow between contractions), and respiratory thoracic pump (diaphragmatic descent creates negative intrathoracic pressure that draws venous blood centrally).
- Superficial veins (great saphenous, small saphenous) drain into the deep venous system through perforating veins. Each junction has valves that prevent blood from flowing from the high-pressure deep system back into the low-pressure superficial system.
Valve Failure and Venous Hypertension
- When venous valves become incompetent (congenital weakness, distension from prolonged hydrostatic pressure, or post-thrombotic damage), blood flows retrograde during periods between calf pump contractions.
- Retrograde flow increases hydrostatic pressure in the superficial venous system — this sustained venous hypertension progressively distends the vein walls, which renders additional valves incompetent (cascade failure).
- Once a valve is rendered incompetent, it cannot be restored — the structural damage is permanent. This is why varicose veins are a chronic, progressive condition.
Tissue Consequences of Chronic Venous Hypertension
- Edema: sustained venous hypertension increases capillary hydrostatic pressure, driving fluid into the interstitium. Chronic LE edema develops, initially pitting and gravity-dependent, worsening throughout the day and improving with overnight elevation.
- Stasis dermatitis: chronic venous congestion causes red blood cell extravasation into the interstitium; hemoglobin degradation produces hemosiderin deposits (brownish discoloration, particularly around the medial malleolus). The chronic inflammatory response produces itching, scaling, erythema, and eczematous changes.
- Tissue induration and lipodermatosclerosis: prolonged inflammation and fibrosis transform soft subcutaneous tissue into hard, woody induration. The skin becomes tethered to deeper structures, producing the characteristic "inverted champagne bottle" leg shape (indurated lower leg with normal upper leg).
- Venous ulceration: in severe CVI, chronic ischemia from impaired microcirculation produces tissue breakdown, typically at the medial malleolus (the most gravitationally dependent and venous-pressure-loaded zone). Venous ulcers are shallow, irregular, with granulating base — distinct from arterial ulcers (deep, punched out, pale base, distal location).
Calf Muscle Pump Dysfunction
- The calf muscle pump is responsible for ejecting approximately 60–70% of venous blood volume from the lower leg with each contraction cycle. In varicose vein disease, two compounding factors degrade pump function:
- Valve incompetence allows blood to fall back after each pump cycle, reducing net upward flow
- Chronic edema and tissue induration reduce the mechanical efficiency of calf muscle contraction against the deep veins
- This creates a self-perpetuating cycle: poor pump function worsens venous stasis, which worsens edema, which further impairs pump function.
- Prolonged standing without walking eliminates the calf pump contribution entirely — venous pressure in the foot veins approaches 90 mmHg (near arterial pressure) in motionless standing.
DVT Risk Association
- Varicose veins are associated with a 2–4 times increased risk of DVT due to venous stasis (one component of Virchow's triad: stasis, endothelial injury, hypercoagulability).
- Superficial thrombophlebitis (clot formation in a varicose vein) can propagate into the deep venous system through perforating veins, producing DVT.
- Any sudden change in a varicose vein — increased pain, warmth, hardness, or redness — requires evaluation for thrombophlebitis and DVT.
Signs and Symptoms
Mild to Moderate Varicose Veins
- Visible dilated, tortuous, bluish superficial veins — most commonly along the medial leg (great saphenous distribution) and posterior calf (small saphenous distribution)
- Spider veins (telangiectasias): small dilated capillary networks, usually cosmetic rather than symptomatic
- Aching, heaviness, and throbbing in the legs, worse with prolonged standing and at end of day
- Itching over varicose veins (early stasis dermatitis)
- Mild dependent edema (ankles and feet) that resolves with overnight elevation
- Symptoms improve with walking (activates calf pump) and elevation; worsen with prolonged standing and heat
Severe Varicose Veins and CVI
- Marked edema that may persist despite overnight elevation
- Stasis dermatitis: hemosiderin staining (brownish discoloration), eczematous changes, scaling, pruritus
- Tissue induration (lipodermatosclerosis) — hard, woody tissue around the medial malleolus
- Venous ulceration: shallow, irregularly bordered ulcers typically at the medial malleolus
- Night cramps (nocturnal leg cramps from chronic venous congestion and metabolic waste accumulation)
- Standing intolerance: inability to stand for more than short periods without significant leg discomfort
- Superficial thrombophlebitis: painful, hard, warm, palpable cord along a varicose vein
Musculoskeletal Compensatory Presentation
- Altered gait from standing intolerance and limb heaviness: shortened stride, reduced push-off, early heel strike
- Calf muscle atrophy or weakness from chronic disuse and impaired contraction efficiency
- Compensatory lumbar and hip tension from altered gait mechanics and limb heaviness
- Ankle stiffness from chronic edema restricting dorsiflexion ROM
- Avoidance of impact activities (running, jumping) due to leg discomfort
Assessment Profile
Subjective Presentation
- Chief complaint: "My legs ache and feel heavy, especially by the end of the day"; "I can see these twisted blue veins all over my legs"; severe: "My ankles are always swollen and the skin around my inner ankle is turning brown and hard"
- Pain quality: deep aching, heaviness, and throbbing in the legs; not typically sharp unless superficial thrombophlebitis develops (then: hot, tender, palpable cord); itching over affected veins; night cramps (sudden, painful calf spasms)
- Onset: gradual, progressive over years; may accelerate during or after pregnancy; occupational standing history is common; superficial thrombophlebitis onset is acute (days)
- Aggravating factors: prolonged standing (primary aggravator), heat exposure (vasodilation increases venous pooling), end of day (cumulative gravitational effect), prolonged sitting with legs dependent, tight clothing or garters that constrict proximal venous return
- Easing factors: elevation of the legs; walking (activates calf pump); compression stockings; cool temperatures; overnight recumbency
- Red flags: Sudden increased pain, warmth, hardness, and redness along a varicose vein — suspect superficial thrombophlebitis; may propagate to DVT; medical referral. Sudden onset calf pain, unilateral swelling, warmth — suspect DVT; do not massage; emergency medical referral. Venous ulceration with signs of infection (increased redness, warmth, purulent drainage, fever) — medical referral.
Observation
- Local inspection: visible dilated, tortuous, bluish veins — note distribution (great saphenous territory: medial thigh and leg; small saphenous territory: posterior calf); spider veins (telangiectasias); skin changes (hemosiderin staining, stasis dermatitis, lipodermatosclerosis, ulceration); ankle edema; compare bilaterally; note any hard, warm, tender segments suggesting thrombophlebitis
- Posture: veins more prominent in standing than supine (gravitational distension); weight shifting to reduce standing load on affected leg; may stand with slight knee flexion to reduce venous pressure
- Gait: reduced push-off phase (calf pump weakness); shortened stride; early heel strike pattern; avoidance of prolonged standing during gait assessment; may report that walking improves symptoms (but prolonged standing worsens them)
Palpation
- Tone: calf muscles (gastrocnemius, soleus) may show reduced tone from chronic disuse or compensatory overuse; proximal compensatory tension in hip flexors and lumbar paraspinals from altered gait; quadriceps may guard if knee edema is present
- Tenderness: varicose veins themselves are tender to direct pressure; medial malleolus region tender if stasis dermatitis or induration present; calf tenderness — distinguish chronic venous aching (diffuse, bilateral) from DVT tenderness (acute, unilateral, deep, localized); hard, warm, tender cord along a superficial vein = thrombophlebitis (do not massage)
- Temperature: skin over varicose veins is typically normal to cool (venous congestion reduces flow velocity); warm, erythematous segment along a vein suggests thrombophlebitis; generalized warmth over the lower leg with edema raises DVT concern; compare bilaterally — unilateral warmth is always significant
- Tissue quality: varicose veins palpable as ropy, soft, compressible distended vessels that empty with elevation and fill with dependency; surrounding tissue may range from normal (early) to edematous and boggy (moderate) to indurated and woody (severe lipodermatosclerosis); skin quality deteriorates progressively — from normal to thin, fragile, and tethered to deeper structures
Motion Assessment
- AROM: ankle dorsiflexion may be restricted by chronic edema (tissue bulk limits range); calf muscle strength may be reduced (weak push-off); hip and knee ROM generally preserved unless compensatory patterns are significant; ankle ROM restriction worsens as edema and induration progress
- PROM / end-feel: ankle dorsiflexion may have a soft/boggy end-feel (tissue edema) or firm end-feel (chronic induration/fibrosis); distinguish from capsular restriction (would show capsular pattern — plantarflexion more limited than dorsiflexion); PROM exceeds AROM when tissue bulk is the primary limiting factor
- Resisted testing: calf muscle (plantarflexion) strength may be reduced; assess with repeated heel raises — inability to complete 10 single-leg heel raises suggests significant calf pump dysfunction; proximal muscles generally normal unless deconditioning from reduced activity is present
Special Test Cluster
| Test | Positive Finding | Purpose |
|---|---|---|
| Trendelenburg Test (CMTO) | Elevate leg to drain veins; compress saphenofemoral junction; stand client up; release compression — rapid filling of varicosities from above = incompetent saphenofemoral valve | Confirm valvular incompetence at the saphenofemoral junction; identifies the primary site of venous failure |
| Perthes Test (CMTO) | Apply tourniquet below knee; client walks for 5 minutes; if varicosities distend (do not reduce) = deep vein obstruction | Assess deep vein patency; positive test = deep venous obstruction; massage contraindicated until deep system evaluated medically |
| Pitting Test (CMTO) | Sustained indentation over the pretibial area or medial malleolus; grade 1+ through 4+ | Quantify associated edema severity; determines drainage treatment parameters |
| Homan's Sign (CMTO — red flag screen) | Calf pain with passive ankle dorsiflexion in the context of unilateral swelling or sudden vein changes | Screen for DVT; positive with acute unilateral findings = medical referral; do not massage |
| Calf Pump Functional Test (Single-Leg Heel Raises) (supplementary) | Inability to complete 10 single-leg heel raises; fatigue or cramping before 10 repetitions | Assess calf muscle pump function; weakness indicates impaired venous return mechanism and guides exercise prescription |
Perthes test determines deep system safety: A positive Perthes test indicates the deep venous system is obstructed. This changes the clinical significance of the superficial varicose veins — they may be serving as compensatory collateral drainage pathways. Massage or compression that eliminates these collateral veins could worsen venous congestion. Medical evaluation of the deep system is required before any drainage treatment.
Differential Assessment
| Condition | Key Distinguishing Feature |
|---|---|
| Deep Vein Thrombosis (DVT) | Acute unilateral calf pain, swelling, warmth, and tenderness; may have palpable cord in the deep compartment; emergency referral; do not massage — risk of pulmonary embolism |
| Peripheral Arterial Disease (PAD) | Intermittent claudication (exertional calf pain relieved by rest); absent or diminished pedal pulses; cool, pale, hairless extremity; ulcers at distal toes (not medial malleolus); ankle-brachial index <0.9 |
| Lymphedema | Non-pitting edema (Stage II+), positive Stemmer sign; does not have visible dilated veins as the primary finding; often unilateral post-surgical; does not respond to elevation after Stage I |
| Superficial Thrombophlebitis | Hot, hard, tender, palpable cord along a superficial vein; overlying erythema; may occur in a known varicose vein; requires medical evaluation to rule out DVT propagation |
| Chronic Compartment Syndrome | Exertional calf pain and tightness with exercise; resolves with rest; tight compartments on palpation during symptoms; no visible varicosities; intracompartmental pressure testing confirms |
CMTO Exam Relevance
- Category: A7 Systemic Conditions
- Trendelenburg test is CMTO-essential — know the procedure and what rapid filling from above indicates (saphenofemoral valve incompetence)
- Perthes test determines whether the deep venous system is patent — positive test (varicosities distend with walking against tourniquet) contraindicates massage until deep system is evaluated
- Varicose veins are not limited to legs — hemorrhoids (anorectal varices), esophageal varices (portal hypertension), and varicoceles (scrotal) are all varicose vein variants
- DVT is the primary red flag — sudden changes in vein quality (increased pain, warmth, hardness) require medical referral
- Know that varicose vein damage is permanent (valve incompetence cannot be restored) — this affects prognosis communication
- Deep tissue massage directly over varicosities is contraindicated; effleurage must be directed toward the heart
- Clients on anticoagulants (DOACs — apixaban, rivarexaban) for DVT history: deep tissue massage contraindicated
Massage Therapy Considerations
- Primary therapeutic target: calf muscle pump rehabilitation, venous return support through positioning and gentle drainage, chronic edema management, and compensatory MSK pain from altered gait. Treatment does not repair incompetent valves but can optimize the remaining functional venous return mechanisms and address the secondary tissue and musculoskeletal consequences.
- Sequencing logic: elevate the legs first (passive gravitational drainage), then begin gentle proximal-to-distal clearing with effleurage directed toward the heart, followed by calf pump activation. The proximal pathway must be opened before distal drainage to avoid overloading already-congested proximal veins. Compensatory MSK work (lumbar, hip) follows drainage work.
- Safety / contraindications: deep specific pressure directly over distended varicose veins is contraindicated (risk of vessel damage, thrombophlebitis initiation). Extreme distorted veins with compromised or leaky skin locally contraindicate massage. Hard, warm, tender segments along a vein (thrombophlebitis) — do not massage; medical referral. All effleurage must be directed toward the heart. Do not apply vigorous techniques that redden the skin — histamine release increases capillary permeability and worsens edema. Clients on anticoagulants (DOACs) contraindicate deep tissue massage throughout (increased bleeding and bruising risk). If Perthes test is positive (deep vein obstruction), do not perform drainage or compression until the deep system is medically evaluated — the superficial varicose veins may be serving as essential collateral pathways.
- Medication awareness: clients with varicose veins and DVT history may be on DOACs (apixaban/Eliquis, rivarexaban/Xarelto) — deep tissue massage is contraindicated for all anticoagulated clients. See Post-2001 Drug Classes for details.
- Heat/cold guidance: alternating hot and cold applications (contrast hydrotherapy) may provide "exercise" for venous smooth muscle in mild superficial varicosities — the alternating vasodilation and vasoconstriction mimics the pump action. Avoid sustained heat alone (vasodilation increases venous pooling). Cold compresses after treatment may help reduce reactive edema.
Treatment Plan Foundation
Clinical Goals
- Support venous return through elevation, gentle drainage, and calf pump activation
- Reduce chronic lower extremity edema (measurable by girth change)
- Rehabilitate calf muscle pump function (measurable by heel raise endurance)
- Address compensatory MSK pain from altered gait and standing intolerance
Position
- Supine with lower extremities elevated 15–30 degrees above heart level on a wedge or stacked pillows — this is the treatment position for the affected legs
- Avoid dependent leg positioning at any point during the session
- For side-lying work: ensure the treated leg remains elevated with pillow support
- Pregnancy modification: left side-lying (reduces IVC compression); do not use prolonged supine in third trimester
Session Sequence
- Position for drainage — elevate legs above heart level; allow 5 minutes of passive gravitational drainage; observe vein distension change (veins should reduce with elevation — if they do not, suspect deep system obstruction)
- Proximal clearing — gentle effleurage to the inguinal region and proximal thigh to open the drainage pathway; light pressure, heart-directed strokes
- Thigh drainage — progressive effleurage from mid-thigh to proximal thigh; light to moderate pressure; avoid deep work over visible varicosities
- Lower leg drainage — gentle effleurage from ankle to knee, directed toward the heart; work around (not directly over) distended varicose veins; use broad, even pressure to distribute load across the tissue rather than point pressure
- Calf muscle pump reactivation — rhythmic compression of the gastrocnemius-soleus complex combined with passive ankle dorsiflexion/plantarflexion; this manually simulates the calf pump action; may combine with active ankle pumps
- Compensatory MSK release — standard MT techniques to the lumbar paraspinals, hip flexors, and quadriceps to address compensatory tension from altered gait; normal treatment pressure is appropriate for these non-edematous areas
- Contrast hydrotherapy application — alternating warm and cool application to the calves for vascular smooth muscle stimulation [mild varicosities with healthy skin only]
- Reassess — girth measurement at standardized ankle/calf landmarks, pitting test, skin color and integrity; compare to pre-treatment
Adjunct Modalities
- Hydrotherapy: contrast hydrotherapy (alternating warm and cool towels, 3 minutes warm / 1 minute cool, 3 cycles) to the calves stimulates venous smooth muscle and provides "passive exercise" for the vascular system; appropriate for mild to moderate varicosities with healthy, intact skin. Avoid sustained heat alone. Cool compresses post-treatment to reduce reactive edema.
- Remedial exercise (on-table): active ankle pumps (20 repetitions) — dorsiflexion/plantarflexion activates the calf muscle pump; single-leg heel raises (begin with bilateral, progress to unilateral as strength permits) to rehabilitate pump function; knee flexion/extension in supine to activate thigh muscle pump contribution.
Exam Station Notes
- Demonstrate Trendelenburg test as part of your assessment — the examiner expects to see valve competence testing for a varicose vein presentation
- Verbalize that deep work directly over varicosities is contraindicated — state this before beginning lower extremity treatment
- Show heart-directed effleurage technique — all strokes move proximally
- If the scenario includes acute changes in a varicose vein (warmth, hardness, tenderness), state that you would screen for DVT and refer medically before treating
Verbal Notes
- DVT awareness: "If you notice any sudden changes in your veins — increased pain, warmth, hardness, or new swelling — please contact your doctor promptly. These changes can sometimes indicate a blood clot that needs medical attention."
- Activity guidance: "Walking is actually one of the best things for varicose veins because it activates the calf muscles that pump blood back up to your heart. Prolonged standing without moving is what we want to minimize."
- Compression garment use: "If your doctor has prescribed compression stockings, wearing them consistently during the day is one of the most effective things you can do between our sessions."
Self-Care
- Walking program (20–30 minutes daily at comfortable pace) to activate the calf muscle pump — walking is more beneficial than standing; avoid prolonged static standing
- Calf pump exercises: heel raises (bilateral, progressing to unilateral) — 3 sets of 10–15 repetitions, 2 times daily; ankle pumps (20 repetitions) when sitting or standing for prolonged periods
- Leg elevation above heart level for 15–20 minutes, 3–4 times daily — particularly at end of day to reverse gravitational fluid accumulation
- Compression stockings (graduated compression, properly fitted by medical supply) worn during all waking hours — most effective when applied before getting out of bed in the morning, before gravitational pooling begins
Key Takeaways
- Varicose veins are permanently distended superficial veins from incompetent valves — once valves fail, normal venous tone cannot be restored; the condition is chronic and progressive
- The Trendelenburg test confirms saphenofemoral valve incompetence; the Perthes test assesses deep vein patency — a positive Perthes test (varicosities distend with walking) contraindicates drainage treatment until the deep system is medically evaluated
- Deep specific work directly over distended varicose veins is contraindicated; all effleurage must be directed toward the heart; avoid reddening the skin
- DVT is the primary red flag — sudden changes in vein quality (increased pain, warmth, hardness) require immediate medical referral; varicose veins carry 2–4 times increased DVT risk
- Calf muscle pump rehabilitation is a key treatment goal — the pump ejection fraction deteriorates as valve incompetence and edema progress, creating a self-perpetuating cycle
- Clients on anticoagulants (DOACs) for DVT history contraindicate deep tissue massage — always screen for anticoagulant use during intake
- Contrast hydrotherapy (alternating warm and cool) provides "exercise" for venous smooth muscle in mild varicosities; avoid sustained heat alone
