Results Of Foam Sclerotherapy


Results of Foam Sclerotherapy



Foam sclerotherapy is a well‑established treatment option for selected varicose veins. We focus on measurable outcomes and continuous improvement, using audited results to refine patient selection and technique so patients receive reliably better care.




Our Results



  • Patients treated: Over 60 foam procedures audited between September 2023 and September 2025

  • 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


Clinical interpretation


High primary closure and a low retreatment rate confirm foam sclerotherapy as an effective option for appropriately selected veins. Transient phlebitis and occasional staining are recognised, manageable outcomes that we actively minimise through technique and structured follow-up.


Audit and quality improvement


We audit every treatment and review results in multidisciplinary meetings. Audit findings are used to improve technique, refine patient selection, update consent conversations, and target training so outcomes continually improve.



Next steps


If you would like to discuss whether foam sclerotherapy is suitable for you or review our audit results in more detail, please contact the clinic to arrange a consultation.


Frequently Asked Questions



How soon will I see results after foam sclerotherapy?


Most patients begin to see improvement within 2 to 4 weeks, with full results developing over 6 to 12 weeks as the treated veins fade.



How effective is foam sclerotherapy for varicose and thread veins?


Foam sclerotherapy is highly effective for medium-sized varicose veins and thread veins. Multiple sessions may be recommended for the best cosmetic and clinical outcome.



Do treated veins come back after foam sclerotherapy?


Treated veins do not return, but new veins can develop over time due to underlying vein tendencies. Follow-up treatment helps maintain long-term results.



Will I need more than one session?


Some patients achieve their desired result in one session, while others benefit from two or more treatments depending on the number and size of veins.



How long do the results of foam sclerotherapy last?


Results are long-lasting. Once a vein is successfully treated, it does not reopen. Maintenance treatment may be needed if new veins appear over the years.
