Physiotherapy Management of Varicose Veins
Introduction
1. Patient Education and Lifestyle Modification
- Avoid prolonged standing or sitting - these positions increase hydrostatic venous pressure and worsen venous pooling.
- Frequent leg elevation - elevation of the legs above the level of the heart periodically throughout the day and during sleep (elevating the foot of the bed 4-6 inches above the heart) facilitates venous drainage by gravity and reduces oedema.
- Weight reduction - overweight and obese patients should be advised to lose weight, as excess body weight increases intra-abdominal pressure and worsens venous hypertension.
- Avoid constrictive clothing - tight garments around the groin or thigh can obstruct venous return.
2. Compression Therapy
Types of Compression
- Maintains relatively constant pressure both at rest and during exercise.
- 20-30 mmHg graduated compression stockings are suitable for most patients with simple varicose veins (CEAP class C2).
- 30-40 mmHg stockings are used for advanced CVI with oedema, skin changes, or venous ulcers (CEAP C3-C6) - this grade is more effective for healing venous ulcers.
- Length: Calf-length stockings are better tolerated by most patients; thigh-length or panty hose are used when varicosities extend to the thigh.
- Graduated compression means maximum pressure at the ankle, decreasing proximally.
- e.g., Unna's paste boot, four-layer bandage, short-stretch bandages, Velcro band devices.
- Demonstrate a more dramatic pressure increase during exercise (since they don't stretch) and lower pressure at rest.
- Better tolerated overnight.
- Preferred during the active treatment/ulcer healing phase of CVI.
- Inelastic compression results in greater improvement in venous haemodynamics compared to elastic compression at the same pressure.
- Multi-component compression is preferred over single-component compression for healing venous ulcers.
- High compression is more effective than medium compression for ulcer healing.
- Once the ulcer heals, the patient transitions to elastic compression stockings for the maintenance phase.
- Elastic stockings = maintenance phase (keep stable condition)
- Inelastic/multilayer wraps = therapy/healing phase (active ulcer treatment)
3. Exercise and Physical Activity
- Walking is the most beneficial activity - it activates the calf muscle pump, which is the main driver of venous return from the lower limbs.
- Leg muscle strengthening exercises - particularly gastrocnemius and soleus strengthening (e.g., ankle pumping, heel-raises) improve calf muscle pump efficiency.
- Exercise training has been shown to improve antegrade venous flow and reduce the severity of chronic venous insufficiency.
- Aquatic exercises / hydrotherapy - water provides natural external compression and reduces venous stasis.
- Ankle exercises (dorsiflexion-plantarflexion pumping) are especially useful for bedridden or sedentary patients to maintain venous return.
4. Intermittent Pneumatic Compression (IPC)
- IPC devices use compressive bladders that inflate and deflate cyclically to provide pulsatile emptying of the venous system.
- Recommended when standard compression therapy has failed, is unavailable, or cannot be tolerated.
- Evidence shows benefit over no compression but limited evidence that it adds benefit over compression therapy alone.
- Useful in immobile patients who cannot perform active exercises.
5. Wound Care for Venous Ulcers
- Wound dressings: Low-adherent absorbent dressings maintain a moist wound environment and absorb exudates.
- Hydrocolloid dressings - polymers like carboxymethylcellulose that absorb exudates as a gel.
- Hydrogel - moisturises dry wounds.
- Foam dressings - absorbent polyurethane-based.
- Alginate dressings - biodegradable, seaweed-derived, for highly exuding wounds.
- Debridement - necrotic tissue is removed to promote healing. Physiotherapists may use sharp, enzymatic, or autolytic debridement depending on scope.
- The compression bandage or stocking is applied over the wound dressing.
6. Cautions and Contraindications in Compression Therapy
- Peripheral arterial disease (PAD): Compression must be used cautiously if ankle-brachial index (ABI) is < 0.8.
- ABI 0.5-0.8: Modified, lower-pressure compression may be used with caution.
- ABI ≤ 0.5 or ankle pressure < 60 mmHg: Compression is contraindicated.
- Uncontrolled cardiac failure (compression may worsen fluid overload).
- Skin infections / acute dermatitis (need treatment first before applying compression).
7. Role of Physiotherapy in Post-Operative/Post-Intervention Rehabilitation
- Early mobilisation - encouraged to prevent deep vein thrombosis (DVT) and restore function.
- Post-procedure compression - after thermal ablation, compression for a minimum of 1 week reduces pain and swelling.
- Ankle and calf exercises - continued to optimise venous return during healing.
- Gradual return to activity - progressive increase in walking and activity under physiotherapy guidance.
8. CEAP Classification and Physiotherapy Goal-Setting
| CEAP Class | Clinical Features | Physiotherapy Focus |
|---|---|---|
| C2 | Varicose veins | Compression 20-30 mmHg, exercise, education |
| C3 | Oedema | Compression 30-40 mmHg, limb elevation, IPC |
| C4 | Skin changes (lipodermatosclerosis, eczema) | High-grade compression, skin care |
| C5 | Healed venous ulcer | Compression for prevention of recurrence |
| C6 | Active venous ulcer | Multilayer compression + wound care + IPC |
