A patient walks into Dr. Raja's Bathinda clinic with a wound on the lower leg that has refused to heal for 6 months. Dressings from the local surgeon, antibiotics, antibiotic creams — nothing has worked. The wound is raw, weeping, painful and gradually enlarging. The patient is exhausted and desperate.
This scenario is far too common across Punjab. Venous ulcers — open sores caused by advanced varicose vein disease — affect approximately 1% of Indian adults and account for massive suffering and disability. The reason they fail to heal with conventional wound treatment alone is simple: the root cause (the leaking varicose vein) has not been treated. Without addressing the venous disease, no wound will heal permanently.
This guide explains everything about venous ulcers — what causes them, why they resist healing, and the combined vein + wound treatment approach that achieves over 90% healing rates.
What is a Venous Ulcer — and Why Does It Form?
A venous ulcer (also called venous stasis ulcer or varicose ulcer) is an open wound on the lower leg — typically on the inner ankle area (gaiter zone) — caused by the final stage of progressive varicose vein disease.
The progression:
- Stage 1–2: Varicose veins develop. Blood pools in leaking veins.
- Stage 3: Chronic venous hypertension (high pressure) causes fluid leakage into leg tissues → ankle swelling.
- Stage 4: Persistent high pressure damages the skin capillaries → skin darkens (lipodermatosclerosis), becomes hard and fragile.
- Stage 5: A small injury, insect bite, or scratch — normally trivial — breaks the fragile skin → wound forms.
- Stage 6: The wound cannot heal because high venous pressure prevents normal tissue repair → chronic venous ulcer.
Without treating the underlying venous hypertension, the wound will always fail to heal or recur after temporary healing.
Why Venous Ulcers Don't Heal with Dressings Alone
The critical insight that most patients are not told:
Dressings, antibiotics and creams treat the wound surface. But venous ulcers are caused by internal pressure from diseased veins forcing fluid outward. Until that pressure is reduced (by treating the varicose veins), the wound environment remains hostile to healing — too much fluid, too much inflammation, too little oxygen.
Studies show that: compression alone heals 50–70% of venous ulcers in 24 weeks. But combining compression with vein treatment (EVLA or foam sclerotherapy) heals 85–95% within 16 weeks, with dramatically lower recurrence.
Diagnosis of Venous Ulcers
Before treating, it is essential to confirm the ulcer is venous (not arterial or diabetic) and identify the responsible veins:
- Colour Doppler Ultrasound: Maps the refluxing veins, confirms venous insufficiency, rules out arterial disease (ABI measurement)
- ABPI (Ankle Brachial Pressure Index): Must rule out arterial disease before applying compression
- Wound assessment: Size, depth, bacteriology, signs of infection
- Blood tests: HbA1c (diabetes check), full blood count, coagulation screen
Complete Treatment Protocol at Dr. Raja's Clinic
Phase 1: Wound Preparation (Weeks 1–4)
- Professional wound debridement (cleaning of dead tissue)
- Advanced wound dressings (hydrofibre, silver foam, compression bandages)
- 4-layer compression bandaging system (reduces venous pressure immediately)
- Management of infection if present
Phase 2: Vein Treatment (When Wound is Prepared)
- EVLA or foam sclerotherapy to ablate the refluxing veins responsible for the ulcer
- This is the definitive step — reduces venous pressure and creates the conditions for healing
- Most patients see significant wound improvement within 2–4 weeks after vein treatment
Phase 3: Wound Healing (Weeks 4–16)
- Continued advanced wound dressing protocol (type selected based on wound characteristics)
- Compression stocking/bandage maintained
- Nutrition optimisation (Vitamin C, zinc, protein)
- Daily walking — critical for venous return and wound oxygenation
Phase 4: Recurrence Prevention
- Class 2 compression stockings for life (or until all reflux is treated)
- Regular Doppler follow-up
- Skin moisturization (prevents re-breakdown of fragile post-ulcer skin)
- Weight management and walking program
When to Seek Urgent Care for a Leg Ulcer
Go to Dr. Raja or emergency care immediately if your leg ulcer shows:
- 🚨 Spreading redness, warmth and swelling (cellulitis — potentially serious infection)
- 🚨 Fever above 38°C
- 🚨 Red streaks extending upward from the wound
- 🚨 Increased pain that was previously stable
- 🚨 Ulcer that has been present for more than 4 weeks without improvement
- 🚨 Any wound on a diabetic patient's leg — diabetic wounds can deteriorate very quickly
Frequently Asked Questions
What is a venous ulcer and how is it different from a normal wound?
A venous ulcer is a chronic, open wound on the lower leg (usually inner ankle) caused by advanced varicose vein disease. Unlike normal wounds, venous ulcers fail to heal because high venous pressure prevents normal tissue repair. They require treatment of the underlying varicose veins — not just wound dressing — to heal permanently.
Can venous ulcers be treated without surgery?
Yes. The most effective non-surgical approach combines: compression bandaging/stockings (reduces venous pressure immediately) + EVLA laser or foam sclerotherapy (treats the leaking veins) + advanced wound dressings. This approach heals 85–95% of venous ulcers within 16 weeks without conventional surgery.
Why does my leg ulcer keep coming back after it heals?
Recurrence happens when the underlying varicose veins (the cause of the ulcer) are not treated. With dressings and compression alone, the ulcer heals temporarily but recurs when the vein pressure continues. Treating the leaking veins with EVLA or foam sclerotherapy reduces 5-year recurrence from 70% to under 20%.
How long does a venous ulcer take to heal?
With proper combined treatment (compression + vein treatment + advanced wound care), most venous ulcers heal within 12–20 weeks. Small ulcers (under 5cm) with good circulation may heal in 6–10 weeks. Large, long-standing ulcers may take 6–12 months. Without treating the underlying veins, healing is indefinitely delayed.
Is venous ulcer treatment covered by insurance?
Yes. Venous ulcers (CEAP Grade C6) are among the most clearly medically covered conditions. EVLA and foam sclerotherapy for venous ulcer treatment are covered by Star Health, HDFC Ergo, ECHS, CGHS and most TPA policies. Wound care dressings are also usually covered under in-patient or day-care benefits.
