Foam Sclerotherapy for Varicose Veins


Foam sclerotherapy is a minimally invasive treatment for varicose veins that avoids the use of heat and large volumes of local anaesthetic. It has become increasingly popular in recent years, particularly for patients who are not suitable for laser or radiofrequency ablation.


Clinical studies show that foam sclerotherapy can be as effective as endovenous heat therapies in selected cases. At our clinic, we do not usually recommend foam as a first‑line treatment, since laser and radiofrequency ablation provide superior long‑term and cosmetic results. However, foam remains an excellent option as an adjunct to other therapies, or as a primary treatment in carefully chosen patients.



How Foam Sclerotherapy Works



  • The sclerosant medication is mixed with air to create a fine foam of micro‑bubbles.

  • The foam is injected into the affected vein, either directly or under ultrasound guidance.

  • Because of its larger surface area, the foam adheres to the vein wall more effectively than liquid, causing the vein to collapse and seal.

  • A needle is inserted into the main superficial vein, and the foam is carefully monitored with ultrasound as it fills the vein.

  • The upper end of the vein may be compressed to prevent foam entering deeper veins.

  • The foam triggers controlled inflammation of the vein wall, leading to closure and absorption of the vein over time.





After the Procedure



  • Additional injections may be required in the same session or at follow‑up appointments to ensure all varicose veins are treated.

  • Patients are usually advised to wear compression stockings for 1–4 weeks to support healing and improve results.

  • Most people can return to normal daily activities immediately, with only mild discomfort or bruising.





Key Benefits of Foam Sclerotherapy



  • Minimally invasive, no general anaesthetic required

  • Performed as an outpatient procedure

  • Effective for medium to large varicose veins

  • Quick recovery with minimal downtime

  • Can be combined with other treatments for optimal results





Our Results



    In our last audit of 60 patients treated purely with foam sclerotherapy, we obtained the following results:

  • Success rate: 89% of treated veins were successfully closed

  • Retreatment: 9% of patients required a second session

  • Complications: 13% experienced temporary phlebitis; 5% had mild skin staining

  • Recovery: Most patients returned to normal activities within days, with high satisfaction and durable symptom relief
