What Is Foam Sclerotherapy?
Foam sclerotherapy is a modern medical procedure used to treat small vein branches and minor varicose veins, especially those that are not suitable for laser treatment. While large, straight veins are usually treated with laser or radiofrequency methods, foam sclerotherapy is ideal for thin, twisted, or surface-level veins.
How the Procedure Works
- A special chemical solution is mixed with air to create a white foam
- This foam is carefully injected into the affected vein
- The foam irritates the inner lining of the damaged vein
- As a result, the vein collapses, seals shut, and is gradually absorbed by the body
Once the faulty vein is closed, blood automatically reroutes through healthier veins.
Why Ultrasound Guidance Is Crucial
Foam sclerotherapy must be performed with ultrasound guidance.
- Ultrasound ensures the foam reaches the exact target vein
- Prevents accidental injection into surrounding tissues
- Improves treatment accuracy and safety
Precision is extremely important. Incorrect placement of the foam can lead to complications such as:
- Skin irritation
- Skin discoloration
- In rare cases, skin ulcers
This is why the procedure should only be done by trained and experienced professionals.
Is the Procedure Painful?
For most patients, foam sclerotherapy is largely painless.
- Mild needle-prick sensation during injection
- Minimal discomfort during and after the procedure
- No cuts, stitches, or anesthesia required
Patients can usually return to normal activities quickly.
What Foam Sclerotherapy Is Best Suited For
Foam sclerotherapy is commonly used to treat:
- Small varicose vein branches
- Residual veins after laser treatment
- Spider veins and reticular veins
- Cosmetic and symptomatic surface veins
It is often used as a complementary procedure rather than a standalone treatment for major vein disease.
Why Professional Expertise Matters
Because accuracy is essential, foam sclerotherapy should always be performed:
- Under ultrasound guidance
- By experienced vein specialists
- With proper patient selection
When done correctly, it is safe, effective, and cosmetically rewarding.
