Treatment for Unwanted Leg Thread Veins

Sclerotherapy is a highly effective treatment for spider veins (telangiectasia) and small varicose veins on the legs. It involves injecting a sclerosing agent directly into the affected veins, causing them to collapse and be gradually reabsorbed by the body. During the healing process, veins may temporarily appear darker before fading over 4–6 weeks. Multiple treatment sessions may be required depending on the severity of the veins, typically 3–6 sessions spaced over time.

Why Choose Sclerotherapy?

Sclerotherapy is often sought for cosmetic improvement, but it can also relieve symptoms caused by problematic veins:

• Aching or heavy legs

• Swelling

• Burning sensations

• Night cramps

How Sclerotherapy Works

Treatment duration is usually up to 30 minutes, depending on the extent of veins treated.

1. You will lie down and the leg(s) will be thoroughly cleaned.

2. The targeted veins are injected with a sclerosing agent using a fine needle. Commonly used agents include:

   • Polidocanol (Sclerovein®)

   • Sodium tetradecyl sulfate (Fibrovein®)

3. The veins may initially disappear and then darken slightly. This indicates that the vein has been sealed and will be naturally reabsorbed.

4. Compression socks or stockings are applied after treatment to support the veins and improve results.

Possible Risks and Side Effects

Common Side Effects (usually temporary):

• Mild cramping, stinging, or burning in the treated vein

• Bruising, redness, or swelling at injection sites

• Skin discoloration (brown marks) which may last 3–6 months

• Multiple tiny red veins or small skin sores

Rare but Serious Side Effects:

• Inflammation – mild swelling, usually managed with over-the-counter pain relief

• Blood clots – very rare; a clot may require further treatment

• Deep vein thrombosis (DVT) – extremely rare; signs include leg pain, swelling, or difficulty bearing weight. Seek immediate medical attention if chest pain, shortness of breath, or coughing up blood occurs

• Ulceration at the injection site

• Allergic reaction to the sclerosing agent

Post-Treatment Care

• Minimal downtime; most clients resume normal activities immediately

• Wear compression stockings for 5–7 days (individual advice given at treatment)

• Avoid strenuous activity, swimming, or gym workouts for 1 week

• Walking is encouraged; avoid standing for prolonged periods

• Elevate legs when sitting

• Avoid flying for 2 weeks after treatment

• A follow-up appointment is scheduled for 4–6 weeks to assess progress

For larger varicose veins, referral to a vascular surgeon may be recommended.

Treatment result may vary from person to person.
