Endovenous Chemical Ablation

Also known as ultrasound guided sclerotherapy, endovenous chemical ablation is another treatment alternative to surgical removal of varicose veins. With this procedure, a chemical irritant, called a sclerosant, is injected into the vein wall while the doctor observes the injection process on an ultrasound screen. This allows veins that are below the surface of the skin to be treated. Such veins cannot be seen by direct vision, they would otherwise require surgical removal. This technique causes the vein to collapse and seal shut, and may be performed with liquid or foamed sclerosant. The procedure is usually performed in a doctor's office and may not require local anesthesia. It is not uncommon for a leg wrap or prescription compression stocking to be placed on the treated leg for 1-2 weeks. Patients are able to walk immediately after the procedure and most individuals are able to return to work the next day.


Mechanochemical Endoveous Ablation (MOCA) (Clarivein)

This is a procedure designed to close (or ablate) veins like saphenous veins. Liquid sclerosant agent of higher concentration are delivered to the interior of the vein using a device with rotating wire which aims at spraying the sclerosing agent into the vein wall leading to much higher rate of permanent closure than doing sclerotherapy alone. The advantages of this procedure:

  • No need for anesthesia or pain medications
  • It avoids heat effect (in heat ablation) on nearby skin or nerves

Laser tends to be precise thou the above advantages are missing. Post operative compression is needed like Endovenous Laser Ablation.
