Stage 6 varicose veins (CEAP C6) means an active open venous ulcer on the leg, usually around the inner ankle. It is the most advanced stage of chronic venous insufficiency — but also the stage where modern treatment can offer dramatic relief, often within weeks. This guide explains the complete C6 treatment protocol used at Dr. Raja's Vein & Intervention Clinic, refined over hundreds of successfully healed ulcers.
How a Venous Ulcer Develops
Years of untreated valve incompetence cause venous hypertension → brown pigmentation → lipodermatosclerosis (woody hard skin) → minor trauma triggers a non-healing wound that enlarges. Without treatment of the underlying veins, the ulcer can persist for years.
The Three-Pillar Treatment Protocol
- Close the diseased vein — EVLA or RFA of the great or small saphenous vein under local anaesthesia. Foam sclerotherapy of feeding branches.
- Multi-layer compression bandaging — the cornerstone. Four-layer or short-stretch bandages applied weekly until healing. Compression stockings (Class III) thereafter for life.
- Wound bed preparation — debridement of slough, appropriate dressings (foam, hydrocolloid, silver-based), infection control.
Expected Healing Timeline
| Week | Expected Outcome |
|---|---|
| 0–2 | Vein procedure done; pain reduces; exudate decreases |
| 2–6 | Granulation tissue starts; ulcer edges contract |
| 6–12 | Most small ulcers (< 5 cm) heal completely |
| 12–24 | Larger or chronic ulcers heal; pigmentation slowly fades |
About 70% of properly treated venous ulcers heal within 12 weeks. Recurrence rate drops from 70% (compression alone) to under 25% when the underlying vein is also closed.
After Healing — Lifelong Prevention
- Class III compression stockings daily for life
- Doppler review every 6 months for the first 2 years
- Skin care — emollients, gentle cleansing
- Weight control, daily walking, avoid prolonged standing
Frequently Asked Questions
Can a stage 6 varicose vein ulcer be cured?
Yes — with the combined approach of vein closure, compression and wound care, the majority of C6 ulcers heal completely within 3 months. Lifelong compression prevents recurrence.
Is laser treatment safe when there is an active ulcer?
Yes — EVLA or RFA is performed under local anaesthesia and is the first step that allows the ulcer to heal. The laser fibre enters at the thigh, away from the ulcer.
How painful is a stage 6 venous ulcer?
Pain ranges from a constant dull ache to severe stabbing. Pain reduces dramatically within 1–2 weeks of the vein procedure as venous hypertension is relieved.
Will the ulcer come back after healing?
With vein closure plus lifelong compression, recurrence drops to under 25% — compared with 70% if compression is used alone. Strict follow-up is essential.
