Many Indians dismiss varicose veins as a "cosmetic problem". They are not. Left untreated for years, varicose veins progressively worsen and can lead to serious medical complications that are far harder and more expensive to treat than the original problem. This guide explains every complication, in order of severity, written by Dr. Ambrish Raja, senior vein specialist who regularly treats advanced cases referred too late.
Stage-Wise Complications (CEAP Classification)
- C2 — Visible varicose veins — cosmetic plus mild symptoms.
- C3 — Edema — persistent ankle swelling.
- C4a — Skin pigmentation & eczema — brown discolouration around the ankle.
- C4b — Lipodermatosclerosis — hard, woody thickening of ankle skin (irreversible).
- C5 — Healed ulcer — previously open sore now closed.
- C6 — Active venous ulcer — open wound that may take 6–12 months to heal.
Acute Complications That Need Emergency Care
- Superficial thrombophlebitis — clot in the varicose vein causing red, hot, painful vein along the leg. Can extend into the deep system.
- Bleeding from a burst vein — minor trauma to a thin-walled varicose vein can cause profuse bleeding. Elevate the leg, apply firm pressure, seek medical care immediately.
- Deep vein thrombosis (DVT) — rare but serious; clot in the deep veins can travel to the lungs (pulmonary embolism).
How To Prevent These Complications
- Don't delay treatment — modern EVLA / RFA / glue procedures are walk-in walk-out and prevent every complication above.
- Wear medical-grade compression stockings daily until treatment.
- Avoid prolonged standing or sitting — move every 60 minutes.
- Maintain healthy weight — reduces venous pressure.
- Treat skin changes early — eczema or pigmentation is the last warning before ulceration.
Frequently Asked Questions
Can varicose veins cause death?
Direct death is extremely rare, but the most serious complication — deep vein thrombosis leading to pulmonary embolism — can be fatal. This is why proactive treatment is recommended.
How quickly do varicose veins worsen?
Progression is typically gradual over years. However, pregnancy, obesity, prolonged standing or a previous DVT can accelerate it dramatically. Once skin changes appear, the disease is in its advanced stage.
Is bleeding from varicose veins dangerous?
Yes — the thin-walled vein can bleed profusely from minor trauma. Apply firm pressure, elevate the leg above heart level, and reach an emergency room immediately. After healing, the underlying vein must be treated to prevent recurrence.
Can a venous ulcer be cured?
Yes — with proper management. The diseased vein is closed (EVLA / RFA), the wound dressed and compression applied. Healing typically takes 8–16 weeks. Untreated, ulcers can persist for years.
