Compression Stockings in DVT and Varicose Veins
What Are Compression Stockings?
Classification of Compression Hosiery
| Class | Pressure at Ankle | Use |
|---|---|---|
| Class 1 | 14-17 mmHg | Mild varicose veins, minor ankle swelling |
| Class 2 | 18-24 mmHg | Moderate varicose veins, mild post-thrombotic syndrome |
| Class 3 | 25-35 mmHg | Severe chronic venous insufficiency, venous ulcers |
- Bailey and Love's Short Practice of Surgery, 28th Ed
Types of Compression
- Elastic compression (stockings, long-stretch bandages) - maintains relatively constant pressure at rest and during exercise.
- Inelastic compression (Unna's paste boot, short-stretch bandages, four-layer bandage, Velcro devices) - demonstrates a more dramatic pressure increase during exercise (beneficial for venous pump), but pressure decreases when recumbent. Better tolerated overnight and over days.
Key point: Inelastic compression achieves greater venous hemodynamic improvement at equivalent pressures compared to elastic compression, and maintains its effect despite gradual pressure loss over time.

Stockings in DVT
1. DVT Prophylaxis (Prevention)
- During long-haul flights (combined with walking every hour)
- Perioperatively in surgical patients
2. Post-Thrombotic Syndrome (PTS) Prevention
- Residual venous obstruction
- Valvular incompetence leading to venous hypertension
- If symptoms are mild-moderate: elevation, avoiding prolonged standing/sitting, occasional analgesics
- If edema is present: lightweight support hose until edema resolves
- If severe symptoms: stocking applying 30-40 mmHg at ankle
3. Venous Ulcers (Severe PTS)

Stockings in Varicose Veins
Role of Compression Hosiery
- Compression hosiery significantly improves varicose vein symptoms (aching, heaviness, throbbing, swelling) - this is well established.
- Symptoms are typically worse at end of day and with prolonged standing; they are relieved by elevation or compression hosiery.
- A therapeutic trial of hosiery can help confirm whether symptoms are truly venous in origin.
What Compression Does NOT Do
- There is no evidence that compression hosiery prevents the occurrence or progression of varicose veins.
- Level 1 trial data show that interventional treatment (endothermal ablation, surgery) offers superior quality-of-life improvement and is more cost-effective than compression alone.
Limitations and Risks
- Compliance is universally poor - patients find stockings uncomfortable and cosmetically unappealing.
- Incorrect application can cause serious harm: pressure necrosis, tourniquet effects.
- Assessment, prescription, and fitting should be done by trained personnel only.
Current Position
Compression is to be regarded as an adjunct to assessment or treatment of varicose veins, unless the patient chooses it over intervention.
- Bailey and Love's Short Practice of Surgery, 28th Ed
Special Considerations
Arterial Occlusive Disease (Contraindication)
- ABI ≥ 0.80: standard compression is safe and effective
- ABI 0.50-0.80 (or ankle systolic pressure ≥60 mmHg): modified lower-pressure compression can still aid ulcer healing
- ABI ≤ 0.50 or ankle pressure <60 mmHg: compression bandages/stockings are not indicated
Stocking Length
- Below-knee vs. thigh-length: no evidence that thigh-length stockings are more effective
- Below-knee stockings are preferred - easier to apply and have much better patient acceptance
Frequency of Change
Summary Table
| Indication | Role of Stockings | Pressure | Evidence |
|---|---|---|---|
| DVT prophylaxis (surgical/flight) | Mechanical thromboprophylaxis | Class 1-2 | Supported |
| Post-thrombotic syndrome | Symptom management, ulcer prevention | 30-40 mmHg | Conflicting for PTS prevention |
| Venous ulcer | Healing adjunct, prevent recurrence | Class 3 | Supported |
| Varicose veins (symptoms) | Symptom relief (adjunct only) | Class 1-2 | Supported for symptoms only |
| Varicose vein progression prevention | Not recommended | - | No evidence |
Generate a decision algorithm for when to recommend compression vs. intervention
A clean, professional medical decision algorithm flowchart titled "Compression vs. Intervention: Venous Disease Management Algorithm". The flowchart should cover two main pathways: DVT/Post-Thrombotic Syndrome and Varicose Veins/Chronic Venous Insufficiency. Start with a top box: "Patient with Venous Disease". Branch into two: "DVT / Post-Thrombotic Syndrome" and "Varicose Veins / CVI". DVT pathway: - Acute DVT → Anticoagulation (primary) → Assess at 3-6 months → Check for PTS symptoms → No PTS: no stocking needed / Mild PTS: Class 2 stocking 30-40mmHg / Severe PTS with ulcer: Class 3 stocking + wound care + consider surgery Varicose Veins/CVI pathway: - First: Check ABI → If ABI ≤0.5: Compression CONTRAINDICATED, refer vascular → If ABI 0.5-0.8: Modified low-pressure compression only → If ABI >0.8: proceed - Then: Assess symptoms + CEAP classification - Mild symptoms, C1-C2, no complications: Trial of compression hosiery (Class 1-2) → Symptoms controlled: continue compression / Symptoms not controlled or patient prefers: refer for intervention - Moderate-severe symptoms, C3-C6, complications (ulcer, bleeding, skin changes): Direct referral for intervention (endothermal ablation / surgery / sclerotherapy) with compression as adjunct - Venous ulcer: Compression (Class 3) + wound care → Healed: maintenance compression for life Use color coding: green boxes for compression, blue boxes for intervention, red boxes for contraindications, yellow boxes for decision points.
