Sclerotherapy
Back

Sclerotherapy is a non-surgical technique used primarily to treat small varicose veins and spider veins. A sclerosing agent is injected directly into the vein, causing irritation and eventual collapse of the vein walls. Over time, the vein is reabsorbed by the body and blood is rerouted through healthier veins. This effective procedure offers both cosmetic and medical benefits by improving the appearance and comfort of legs affected by vein disorders.

Types of Sclerotherapy Procedure

  • 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.

Key Takeaways

  • Type of Procedure: Minimally invasive, non-surgical.
  • Duration: 15 to 45 minutes per session.
  • Anesthesia Used: None or local anesthesia (if required).
  • Recovery Time: Return to light activities the same day and full recovery in a few days.
  • Success Rate: Approximately 80-90% success in treating targeted veins.

Sclerotherapy Indications

Sclerotherapy is a trusted treatment option for individuals dealing with unsightly or uncomfortable veins. It's especially useful when symptoms persist despite lifestyle changes.

Here are the most common reasons people consider this procedure:

  • 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.

Sclerotherapy Treatment Benefits and Side Effects

Sclerotherapy offers both cosmetic and health advantages for people struggling with vein problems. It's a convenient, effective option that fits easily into most lifestyles.

Benefits of Sclerotherapy

  • Improves the appearance of veins.
  • Non-surgical with no general anesthesia or incisions.
  • Quick recovery and minimal downtime.
  • Long-lasting results (veins fade within weeks/months).
  • Minimal discomfort during the procedure.
  • No hospital stay required.
  • Improved circulation reduces pain, edema, and discomfort.
  • Customizable for veins of different sizes/locations.

Sclerotherapy Side Effects and Complications

While generally safe, sclerotherapy can cause temporary side effects and, in rare cases, more serious complications. Knowing what to expect can help you make an informed decision.

  • Temporary bruising, redness, itching, or mild discomfort.
  • Skin discoloration (temporary).
  • Rare complications: Blood clots or deep vein thrombosis (DVT), allergic reaction to the solution and ulceration at the injection site.

Sclerotherapy Aftercare and Recovery

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.
  • Compression Garments: Wear stockings/bandages as advised.
  • 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.
