What is ClariVein?

ClariVein is a minimally invasive, ultrasound-guided endovascular treatment for varicose veins.

What Happens During the ClariVein Procedure?

ClariVein is a minimally invasive, in-office procedure that concludes within 30 minutes with no downtime. Your vein physician will numb a small area on your legs and make an incision to insert a specialized catheter into the diseased vein under ultrasound guidance. The catheter, when activated, will destroy the diseased vein’s walls while injecting sclerosant medicine to fuse it shut. You may experience mild post-treatment discomfort and bruising, but you can resume your daily activities immediately.

What is the ClariVein Device?

The ClariVein device is a specialized catheter, a hollow needle with a rotating wire tip. When activated, the rotating wire damages the diseased vein’s walls while injecting a sclerosant medicine, which fuses the vein’s walls. As such, it can treat vein disease without using thermal energy or laser energy.

Can ClariVein treat unhealthy veins on the face, hands, and feet?

ClariVein is only used to treat large, tortuous varicose veins because it damages the vein’s walls using a specialized rotating wire tip. It shouldn’t be used to treat small veins with dense arterial connections on the hands, feet, and face.


What are the Side Effects of ClariVein?

Venaseal treatment side effects can include:

Numbness and tingling sensations on the legs (common)

Skin discoloration and darkening on the treatment area (rare)

ClariVein is an extremely safe procedure with a negligible risk of harsh side effects and complications. You can alleviate the side effects with medications or skin creams. Furthermore, you can avoid some of the side effects by consulting reliable and experienced vein doctors in Long Island.
