A Common, Often Dismissed Condition
Chronic venous insufficiency (CVI) affects an estimated 25 million Americans. It causes heavy, aching legs, swelling, skin changes, and — in advanced cases — venous ulcers. Despite how common and treatable it is, CVI is frequently dismissed as cosmetic or a normal consequence of aging.
It is not. CVI is a progressive disease, and early treatment dramatically slows progression. At Zimmer Medical Group, we treat venous symptoms as the medical issue they are, not just an appearance issue.
Understanding Venous Return
Veins in the legs work against gravity to return blood to the heart. They rely on:
- One-way valves that prevent backflow
- The calf muscle pump that propels blood upward with walking
- Healthy vein walls that maintain proper diameter
When valves fail or vein walls weaken, blood pools in the legs (venous reflux), increasing pressure and causing the symptoms of CVI.
Risk Factors
- Age (risk rises substantially after 50)
- Female sex (especially after multiple pregnancies)
- Family history of venous disease
- Obesity
- Prolonged standing or sitting (common in nursing, hospitality, retail, office work)
- Prior deep vein thrombosis (DVT) — see our DVT in snowbirds article
- Previous leg trauma
- Smoking
Recognizing the Symptoms
CVI exists on a spectrum:
Early Symptoms
- Heavy, tired, aching legs — particularly at end of day
- Swelling, often worse in the afternoon
- Burning or cramping in the legs
- Restless legs at night
- Itching of the legs and ankles
Visible Changes
- Spider veins (telangiectasias) — small surface vessels
- Reticular veins — bluish veins below the surface
- Varicose veins — bulging, twisted, larger veins
- Ankle and lower leg swelling
- Skin discoloration (brown or rusty staining from hemosiderin deposition)
- Skin thickening (lipodermatosclerosis)
Advanced Disease
- Venous eczema — red, itchy, scaly skin
- Atrophie blanche — white, scarred patches
- Venous ulcers — slow-healing wounds, typically near the inner ankle
- Severe lipodermatosclerosis — woody, narrow ankle ("inverted champagne bottle" appearance)
The CEAP classification (Clinical, Etiology, Anatomy, Pathophysiology) is the standard system clinicians use to grade severity.
What Else to Consider
Several conditions can mimic or coexist with CVI:
- Deep vein thrombosis — sudden swelling, calf pain, warmth; requires urgent evaluation
- Lymphedema — pitting that becomes non-pitting over time, often after surgery, infection, or radiation
- Heart failure — bilateral edema with shortness of breath, fatigue
- Kidney disease — bilateral edema with other systemic features
- Cellulitis — acute redness, warmth, pain, often fever
- Medication side effects — calcium channel blockers, NSAIDs, gabapentin, certain diabetes medications
A thorough history, exam, and selective testing distinguish these.
Diagnostic Evaluation
The cornerstone test for CVI is venous duplex ultrasound. This exam:
- Maps the deep and superficial venous systems
- Identifies sites of valve failure (reflux)
- Documents venous diameter
- Excludes acute DVT
- Guides treatment planning
Other tests are rarely needed for routine CVI but may be used in complex cases.
Conservative Treatment
For most patients, conservative measures should be tried for at least several months before considering procedures.
Compression Therapy (The Cornerstone)
- Graduated compression stockings — typically 20–30 mmHg or 30–40 mmHg for symptomatic CVI
- Worn during the day, removed at night
- Help with symptoms, swelling, and slowing disease progression
- Required by most insurance before approving procedures
- Many patients struggle with adherence due to discomfort or difficulty putting them on
For Florida residents, compression stockings can be challenging in heat. Lighter-weight options and proper sizing dramatically improve adherence.
Leg Elevation
Elevating legs above heart level for 15–30 minutes several times per day reduces swelling and gives veins a chance to drain.
Exercise
Walking activates the calf muscle pump, which is the primary mechanism returning blood to the heart from the legs. Daily walking is one of the most effective interventions.
Weight Management
Excess weight increases venous pressure. Even modest weight loss often dramatically improves symptoms.
Skin Care
For patients with skin changes:
- Daily moisturizing
- Treatment of any eczema or fungal infection
- Avoidance of trauma to the lower legs
Procedural Options
For patients with significant symptoms or skin changes who fail conservative therapy, procedures are often dramatically effective.
Endovenous Ablation
The current standard for treatment of saphenous vein reflux. Uses laser energy (EVLA) or radiofrequency (RFA) inserted through a small catheter to seal the failing vein. Performed in office or outpatient setting under local anesthesia. Most patients return to normal activity the same or next day.
VenaSeal (Cyanoacrylate Closure)
A newer alternative using medical-grade adhesive instead of heat to close the vein. Avoids the need for tumescent anesthesia along the vein.
Mechanochemical Ablation (ClariVein)
Combines mechanical disruption with a sclerosing agent. Another non-thermal option.
Sclerotherapy
Injection of a sclerosing agent into smaller veins (foam sclerotherapy for varicose veins, liquid sclerotherapy for spider veins). Often combined with primary saphenous treatment.
Phlebectomy
Surgical removal of bulging varicose veins through tiny incisions. Often combined with endovenous ablation.
Surgery
Traditional vein stripping is rarely performed today, having been largely replaced by endovenous techniques with similar effectiveness and faster recovery.
What Insurance Typically Covers
For symptomatic CVI with documented venous reflux on ultrasound, most insurance plans (including Medicare) cover:
- Compression stockings
- Endovenous ablation when symptoms persist after 3 months of conservative therapy
- Phlebectomy in conjunction with primary treatment
Purely cosmetic treatment of spider veins is not typically covered.
Preventing Progression
For early or mild CVI:
- Daily walking
- Compression during prolonged standing or air travel
- Maintain healthy weight
- Avoid prolonged sitting (especially with crossed legs)
- Elevate legs when possible
- Treat aggravating conditions
The Society for Vascular Medicine and the American Venous Forum provide additional patient resources.
When to See Your Doctor
- Persistent leg swelling, heaviness, or aching
- Visible varicose veins causing symptoms
- Skin discoloration or thickening on the lower legs
- Itching, burning, or restless legs
- Any non-healing wound on the lower leg or ankle
- Symptoms not improved by basic conservative measures
