Radiofrequency (Closure™)

The Endovenous Radiofrequency Ablation (EVRFA) procedure is a minimally invasive treatment that uses radiofrequency (RF) energy to effectively treat patients suffering from varicose veins or Chronic Venous Insufficiency (CVI). Our Vein Institute Of Toronto specialist, Dr. Sanjoy Kundu, inserts a catheter into a varicose vein to provide consistent and uniform heat to contract the collagen in the vein walls, causing them to collapse and close. After the vein is sealed shut, blood is then naturally redirected to healthy veins. The vein simply becomes fibrous tissue after treatment. Over time, the vein will be completely absorbed into the surrounding tissue.

Tumescent anesthesia is one of the major advances in vein surgery. Tumescent means swelling or distention. When we administer tumescent anesthesia, the tissues are flooded with dilute liquid anesthetic and become distended giving an appearance resembling the outside of an orange. The unique feature of tumescent anesthesia is that it involves the use of a very low concentration of local anesthetic. The anesthesia achieved by this technique is excellent and has a prolonged duration, allowing the patient to get home long before the anesthesia wears off. Additionally, the post-operative discomfort seems remarkably diminished.
