What is ClariVein®?

We are now offering a new treatment for varicose veins called ClariVein® at all of our vein treatment centers. The Clarivein® procedure will be available to patients living with venous insufficiency in addition to our Endovenous Laser Treatment (EVLT), Ultrasound-Guided Sclerotherapy (USGS) and Varithena treatments.

ClariVein® is a technique of treating venous insufficiency, also known as vein disease, without the use of laser energy. It is a catheter-based treatment that simultaneously uses mechanical and chemical methods to treat the damaged area.

ClariVein® is:

  • Clinically proven
  • Non-thermal (no laser used)
  • Low profile
  • FDA-approved
  • Covered by most insurances

ClariVein® Procedure: What to Expect

The ClariVein® procedure works by treating the affected veins internally through a very small incision usually on the upper thigh area. During the procedure, a medical catheter with a rotating fiber on the end is inserted into the vein.

Once the device reaches the damaged vein, the fiber begins to rotate. As the fiber rotates, it carefully removes the lining of the damaged vein, while also delivering a medical solution to treat the underlying cause. The catheter will continue to rotate for several minutes, and there may be a light humming sensation near the affected area, but it should not cause any major pain or discomfort. In contrast to EVLT and Sclerotherapy, ClariVein® uses two modes of action to treat the damaged vein and the underlying cause.

Similar to other treatments that we offer at USA Vein Clinics, this procedure is performed with local sedative and is performed in an office-based setting at our vein treatment center. The treatment session can be completed in as little as 30 minutes. Since no major incision is made and none of the tissue surrounding the affected area is damaged, there is very little chance of scarring or bruising. After their ClariVein® treatment, patients are able to return to normal activities almost immediately.

Is ClariVein® Safe?

In 2017 there was a study[1] conducted in the UK published through SAGE journal, that includes useful information about the safety and success of ClariVein® treatment. The study, titled “ClariVein®- Early Results from A Large Single-Center Series of Mechanochemical Endovenous Ablation for Varicose Veins”, focused on the effectiveness and patient experience of the treatment.

The results of the study revealed that of all 393 procedures for venous insufficiency completed using ClariVein®, only 3.3 percent required a second treatment session after the eight-week checkup. The study also found that the average pains score reported across all 393 procedures was only .8 on a scale of 1-10. However, it is important to understand that every person’s pain tolerance and treatment experience varies.

The Benefits of This Treatment

The ClariVein® procedure is less invasive than other vein treatments that are available for venous insufficiency as it does not require multiple incisions to be made or multiple injections of anesthesia. It is a non-thermal treatment method, meaning that it does not use laser energy to close damaged veins. These two factors result in a shorter recovery time for less-severe cases, and a reduced likelihood of developing complications after the procedure. Since the catheter on the ClariVein® instrument is very small, it does not require a major incision to be made which means a decreased risk of bruising, scarring, or damaging of nearby veins and tissues.
