What is Sclerotherapy?
Sclerotherapy is a non-surgical procedure used to treat small varicose veins and spider veins. A special solution (sclerosant) is injected directly into the vein, causing it to collapse and fade over time. The body naturally reabsorbs the treated vein, improving circulation and leg appearance.
Types of Sclerotherapy Procedure
Sclerotherapy can be performed using different techniques depending on the size, depth, and location of the affected veins. Each type of sclerotherapy procedure is designed to improve precision, effectiveness, and cosmetic results.
- Traditional Sclerotherapy: Used for smaller veins like spider veins or small varicose veins. A sclerosant solution is injected into the vein, causing it to collapse and fade over time.
- Foam Sclerotherapy: This treatment is more successful for more noticeable varicose veins and involves injecting a foam sclerosant. Better outcomes are ensured by the foam's improved ability to make contact with the vein walls.
- Ultrasound-Guided Sclerotherapy: For deeper veins or veins not visible on the skin's surface. Ultrasound imaging guides the sclerosant injection for precise placement.
- Laser-Assisted Sclerotherapy: Combines sclerotherapy with laser energy to target veins. The laser aids with vein closure before sclerosant injection.

When is Sclerotherapy Recommended?
Sclerotherapy is usually advised for people with vein problems that don't improve with lifestyle changes or compression stockings. Sclerotherapy indications include:
- Visible spider veins or small varicose veins causing discomfort or aesthetic concerns.
- Symptoms like aching, swelling, burning, or cramping in the legs.
- Failure to improve with lifestyle changes (exercise, compression therapy).
- Risk of complications like venous insufficiency or ulceration.
- Non-surgical alternative to vein stripping or laser therapy.
How to Prepare for the Sclerotherapy Procedure?
Proper preparation helps ensure a smooth and successful sclerotherapy experience. Following your doctor's instructions before the procedure can reduce risks and make recovery easier.
Be sure to:
- Avoid lotions/oils on legs before treatment.
- Wear loose, comfortable clothing.
- Avoid blood-thinning medications (aspirin, ibuprofen) unless directed.
- Bring compression stockings if instructed.
- Inform your doctor of allergies or medical conditions.
- Stay hydrated and have a light meal if advised.
What Happens During the Sclerotherapy Procedure?
The treatment itself is quick and typically done in a clinic setting. It's a minimally invasive process that targets affected veins directly.
Here's what usually happens:
- Cleansing: Treatment area cleaned with antiseptic.
- Injection: Fine needle injects sclerosing solution into the vein.
- Reaction: Solution irritates the vein lining, causing collapse.
- Compression: Leg wrapped with compression stockings.
- Multiple Injections: Several veins treated per session.
- Observation: Rest briefly before discharge with aftercare instructions.
Who Will Perform Sclerotherapy?
Sclerotherapy is a minimally invasive procedure performed by trained medical specialists to safely treat varicose veins or spider veins.
Dermatologists
- Many dermatologists specialize in vein treatments and cosmetic skin procedures.
- They evaluate the veins and perform injections of the sclerosant solution.
Vascular Surgeons
- Surgeons trained in vascular medicine often perform sclerotherapy, especially for larger or deeper varicose veins.
- They can combine sclerotherapy with other vein treatments if necessary.
Interventional Radiologists
- In some cases, interventional radiologists use imaging guidance to perform sclerotherapy for complex veins.

Post-treatment care is important for healing and ensuring the best results. Most people can return to daily activities quickly, but certain habits can promote faster recovery.
After the procedure:
- Immediate Recovery: Resume normal activities; walk to improve circulation.

- Hydration: Stay hydrated to support healing.
- Avoid Sun Exposure: Prevent pigmentation issues.
- Exercise: Light walking; avoid heavy activities for a few days.
- Follow-Up: Track progress and determine if additional treatments are needed.
- Results: Veins fade over weeks; multiple sessions may be required.
- Possible Side Effects: Bruising, discoloration, or mild itching (temporary). Contact your doctor if severe pain/swelling occurs.
