ClariVein Procedure FAQs


How is the ClariVein procedure different from other varicose vein treatments?
ClariVein is a specialty infusion catheter with a rotating wire tip designed for the controlled 360-degree dispersion of physician-specified agents to the targeted treatment area. Use of the Clarivein  does NOT require painful anesthesia and will not cause thermal agitation.  Compared EVLT and Venefit, ClariVein eliminates the need for multiple needle sticks of anaesthesia and pre-procedure drugs. Unlike other varicose vein treatments, there is virtually no downtime and little to no discomfort.


Does ClariVein require anesthesia?
No. The ClariVein procedure requires no anaesthesia to be injected into the leg; only a small amount of numbing medicine at the access site is used.


Is the ClariVein  procedure painful?
Patients treated with the Clarivein system have reported little to no pain or discomfort, both during and after the procedure.


What can I expect afterwards?
After the procedure, a small bandage will be placed over the access site and you should be able to return to your normal activities.


Is there any scarring, bruising, or swelling after the procedure?
Patients have reported minimal to no scarring, bruising, or swelling following the ClariVein procedure.


What kind of results can I expect?
Results depend on the degree and extent of your varicose veins. However, patients have reported immediate relief from their uncomfortable symptoms. In addition, patients can expect the appearance of their legs to improve after the procedure.


What risks, if any, are associated with the procedure?
As with any medical treatment there are potential risks and complications that exist with the ClariVein procedure. Your doctor will be able to review potential complications of the procedure during your visit.  These risks may include thrombosis, DVT, phlebitis, bleeding, or infection.

What happens to the treated vein left behind in the leg? Don’t I need it?
After treatment, the affected vein becomes fibrous tissue. Over time, the vein will be absorbed into surrounding tissue and blood will re-route to other veins.

Is the ClariVein procedure covered by insurance?
OHIP does not cover the ClariVein procedure.  Some private insurance providers may cover the cost.  Consult your personal plan to determine coverage.  After your assessment, KW Vein Clinic may provide information to your insurance plan.


Is the ClariVein procedure for everyone?
Your doctor will be able to tell you if the ClariVein procedure is the right option for you. Most patients with varicose veins would benefit from the ClariVein procedure.

ClariVein Treatment

The ClariVein procedure is an alternative treatment option to traditional vein stripping surgery.  It avoids the risks of general anesthesia and the prolonged recovery, discomfort, and scarring associated with vein stripping.  The ClariVein procedure is performed on an outpatient basis. ClariVein is a specialty catheter with a unique rotating tip. The system promotes controlled, effective coverage of a sclerosant medicine to treat the diseased vein.  The ClariVein catheter is a slim, thin catheter (tube) that your doctor temporarily inserts into the vein through a pin-sized entrance point.  Using ultrasound guidance, the tiny rotating tip of the ClariVein catheter is set in motion to treat the inside of the vein.  As the catheter is pulled back, the vein is treated along its length.  At the end, the catheter is withdrawn, and ultrasound is carried out to confirm closure of the vein.

Unlike other treatments (EVLT or Venefit), ClariVein does not require anaesthesia to be injected into the leg via multiple needle sticks (tumescent anesthesia), and because there are no pre-procedure drugs involved, patients can return to their normal activities right after the treatment. Unlike heat-based procedures, with ClariVein there is no risk of skin burns or nerve damage.
