This article is for informational purposes only. The decision to perform the procedure should be based on venous mapping and physician evaluation.
Foam sclerotherapy is a form of sclerotherapy in which the medication is mixed with air or gas to create foam. Under ultrasound guidance, the foam can be directed into selected varicose veins and refluxing branches.
When Is It Considered?
- Residual varicose branches after main vein treatment
- Recurrent varicose veins in selected patients
- Veins that are not ideal for laser or radiofrequency
- Some perforator-related or branch-related reflux patterns
- Patients who need a minimally invasive outpatient option
Procedure Steps
The target vein is identified with ultrasound. The physician places a needle into the vein, injects the foam and monitors its distribution. Compression is usually applied afterward, and walking is generally encouraged.
Advantages
- No surgical incision in most cases
- Can be performed under local conditions
- Useful for tortuous branches
- Can treat veins that are difficult to reach with a catheter
- Short recovery in many patients
Risks and Points to Consider
Temporary bruising, tenderness, pigmentation and trapped blood can occur. Rarely, visual symptoms, migraine-like symptoms, allergic reaction or clot extension may develop. For this reason, patient selection and ultrasound guidance are important.
Results After Foam Treatment
Veins usually fade gradually over weeks to months. More than one session may be needed depending on vein burden and the underlying reflux pattern. Long-term success depends on treating the source of venous pressure, not only the visible veins.
