ClariVein (MOCA - Mechanical Chemical Ablation) Q & A

by Bruce Hoyle, M.D.

What Is ClariVein?

ClariVein is a special device used to close off incompetent truncal veins. The treatment consists of inserting a catheter that has a rotating wire. The wire has a 360-degree dispersion of agents used to treat the area. It’s a minimally invasive procedure that doesn’t require a person to stay overnight at a hospital. In fact, it is performed in the office.

How Is ClariVein Performed?

The phlebologist will insert a thin catheter, similar to an IV insertion. Inside the catheter is a wire connected to a motorized handle, which spins the wire very quickly. About an inch of the wire extends past the catheter, causing a spasm of the vein. As the catheter and wire are withdrawn, a sclerosant solution is slowly injected, which closes the vein.

Is ClariVein Right for Me?

The physician will need to do a thorough ultrasound evaluation of the veins to determine the size and severity. This will allow the physician to determine if the procedure is right for the patient’s specific needs. ClariVein is not covered by all insurances, which may not make it the best viable option for many patients. A physician will be able to determine if ClariVein is the best treatment. 

What Are the Risks of ClariVein?

In some parts of the leg, there can be a risk of nerve damage with radiofrequency ablation or laser ablation. Since ClariVein does not use heat, there is no risk of nerve damage, which is an advantage in selecting this treatment. Generally, the patient won’t experience any pain. Bruising, itching, or pain is possible at the site but is minimal and temporary. Infection is possible but isn’t likely because of the small size of the entry point. It’s possible to have a reaction to the medications used. Additionally, skin discoloration is possible with this procedure, like most other varicose vein treatments, but rare. The patient may experience discomfort from the rotating wire, but it goes away once the procedure is completed.
