Endovenous Radio-Frequency Ablation (RFA) and Endovenous Laser Therapy (EVLT) both use thermal energy to effect vein closure. RFA has been shown to cause less pain and bruising than EVLT and is the treatment of choice at The Vascular & General Surgery Centre.
Chemical ablation has been available for some time, but is gaining more interest with the introduction of Clarivein. Clarivein is a device that irritates the inner lining of the vein with a rotating metal tip and injects a chemical at the same. The combination of these two irritative mechanisms results in very effective vein closure with minimal discomfort. Clarivein is offered at The Vascular & General Surgery Centre.
Complications are minor. Bruising is common but will always resolve within 2-3 weeks. Small areas of numbness occurs in about 7% of patients but most resolve with time.
