Sclerotherapy

Sclerotherapy involves injecting a special solution, called a sclerosant, directly into the affected vein. This solution irritates the lining of the vein, causing it to collapse and stick together. Over time, the treated vein turns into scar tissue and fades from view as the body naturally reroutes blood flow to healthier veins nearby.

The procedure is typically performed in a doctor’s office, requires no anesthesia, and takes about 15 to 45 minutes, depending on the number and size of veins being treated.

Sclerotherapy is an excellent option for many people, but not everyone. You may be a good candidate if you:

• Have spider veins, small varicose veins, or reticular veins (the greenish-blue veins that feed spider veins).
  
• Are experiencing symptoms from your veins, such as aching, swelling, burning, or night cramps.
  
• Are bothered by the appearance of your veins.
  
• Are in good overall health.
  
• Are not pregnant or breastfeeding.
  
• Have realistic expectations about the results.

You may not be a good candidate if you:

• Are pregnant or nursing.
  
• Have a history of blood clots (deep vein thrombosis or DVT).
  
• Have severe chronic health conditions, such as uncontrolled diabetes or heart disease.
  
• Have an active infection, inflammation, or skin rash in the area to be treated.
  
• Are immobile or bedridden.
  
• Are allergic to the sclerosant solution.

A consultation is essential to determine if sclerotherapy is right for you.

Sclerotherapy can be used to treat a range of abnormal veins, which differ in size and location:

1. Spider Veins (Telangiectasias): These are the smallest, appearing as fine red, blue, or purple web-like lines just under the skin’s surface. They are primarily a cosmetic concern.
   
2. Reticular Veins: Often called “feeder veins,” these are greenish-blue and slightly larger than spider veins. They can be a source of spider veins and sometimes cause minor symptoms.
   
3. Small Varicose Veins: These are enlarged, rope-like veins that bulge from the skin. While larger varicose veins may require different treatments (like endovenous ablation), smaller ones respond very well to sclerotherapy.

During the Procedure:

• You will lie down comfortably, and the skin over the vein will be cleaned.
  
• Using a very fine needle, the doctor will inject the sclerosant solution into the targeted veins.
  
• You may feel mild, temporary stinging, burning, or cramping at the injection sites.
  
• The number of injections needed depends on the number and size of veins being treated.

Immediately After the Procedure:

• The doctor may massage the area to disperse the solution.
  
• Compression bandages or stockings will be applied to the treated areas. You will be instructed to wear them as directed.
  
• You will be encouraged to walk immediately to promote circulation and prevent blood clots.

Sclerotherapy is a very safe procedure when performed by an experienced professional. However, as with any medical treatment, there are potential risks and side effects.

Common, Temporary Side Effects:

• Bruising, Redness, or Swelling: At the injection sites; usually clears within a few days.
  
• Itching: Around the treated area, which can last for a day or two.
  
• Raised Red Areas: These should disappear within a few days.
  
• Brown Lines or Spots: Caused by the trapped blood pigment (hemosiderin) leaking from the treated vein. This usually fades over several weeks or months but can occasionally be permanent.

Less Common Risks:

• Inflammation: Larger treated veins can become lumpy, hard, and inflamed. This is not dangerous and can be relieved with warm compresses and aspirin (if approved by your doctor).
  
• New Spider Veins (Matting): The appearance of new, fine red blood vessels near the treatment area. These may fade on their own or require further treatment.
  
• Allergic Reaction: To the sclerosant solution (very rare).
  
• Blood Clot: A small clot can form in a treated vein, which can be drained by your doctor if necessary.
  
• Skin Ulceration or Necrosis: A very rare but serious complication where the solution leaks into surrounding tissue, causing a small sore. This requires medical attention.

Proper aftercare is crucial for achieving the best results and minimizing complications.

• Wear Compression Stockings: You will typically need to wear medical-grade compression stockings continuously for a specified period (often 2-3 days and nights), then during the day for 2-3 weeks. This helps compress the treated veins and ensures they seal shut.
  
• Stay Active: Walk regularly. Avoid strenuous exercise, heavy lifting, and prolonged standing or sitting for the first 1-2 weeks.
  
• Avoid Certain Activities: No hot baths, saunas, or hot tubs for at least 48 hours.
  
• Avoid direct sun exposure to the treated areas for several weeks, as it can cause dark pigmentation.
  
• Do not apply hot compresses or take aspirin/ibuprofen unless directed by your doctor (to reduce bruising).
  
• Follow-Up Appointments: Most patients require multiple sessions spaced 4-6 weeks apart to achieve optimal results. Your doctor will schedule a follow-up to assess your progress.

Results: Treated veins begin to fade within a few weeks, but it can take 3 to 6 months to see the full cosmetic improvement. While sclerotherapy effectively eliminates existing veins, it does not prevent new ones from forming in the future.
