ClariVein, also known as mechanochemical ablation, is used to treat spider veins, varicose veins, and venous insufficiency. Venus insufficiency can cause by several factors, mainly caused by varicose veins and blood clots. People with Venus insufficiency have weaker veins that need treatment to work properly. Different treatments are available, including ClariVein, Endovenous Laser Treatment, vein ablation, etc. In this article, we will discuss the ClariVein procedure. How does it benefit venous insufficiencies? How to prepare for this procedure? In this article, we will also determine the possible risks and side effects of ClariVein.

What Is ClariVein?

The clarivein method involves making a small incision in the upper thigh and inserting a medical catheter with a rotating fiber on its end to treat the affected veins. Once the gadget reaches the injured vein, the rotating fibers begin to rotate and remove the lining of the injured vein while also treating the underlying cause. The patient may feel a slight humming rather than pain or discomfort. Clarivein cures the damaged vein and its underlying cause without using laser technology, unlike other methods like EVLT and Sclerotherapy that close the damaged vein.
The procedure can be completed in 30 minutes without a significant incision and carried out in an office-based setting using local anesthesia. It makes the procedure efficient and comparatively less painful. Because of a small incision, and no tissue is damaged nearby the damaged area, the possibilities of bruising and scarring are minimal. For venous insufficiency, the ClariVein method is less disturbing than other treatments, and most patients don’t require a second surgery later; as a result, the patients recover quickly.

Is ClariVein Safe?

Most surgical treatments are always painful. But ClariVein is most effective or painless because it is almost non-invasive. It might have a painful sensation, but it depends on person to person and their pain tolerance. Secondly, research shows that 97% of the patients treated with the ClariVeins procedure after the first session do not require a second treatment session for their venous insufficiencies.
ClariVein is not a heat-dependent procedure or nonthermal, so there is no risk of burning sensation and nerve damage in this process. There are lower risks of bruising, burning, and vein damage because ClariVein is a small instrument and does not want a significant incision.

Educate yourself about the procedure’s possible risks and side effects. After the ClariVeins procedure, you may experience the following:

  • The person may feel restlessness after the procedure, and it is because of the small incision during the treatment. Many people do not feel any discomfort, but if you have sensitive skin, then discomfort along with itchiness and little pain can occur, but it will go away on its own, and the range of pain is related to the size of damaged veins. Exercising and walking will help to improve the pain.
  • A few tiny spider veins may start visible or close to the surface skin. Spider veins are small twisted colored veins, usually painless, but the person may have cosmetic concerns about them. It may occur when blood is diverted to healthier veins after ClariVein closes the affected veins. A little bit of blood may travel through small arteries during this procedure. After your final session, your vascular expert might advise sclerotherapy to eliminate superficial veins.
  • The procedure may cause discoloration in the affected area. Discoloration may appear as bruising or as in dark spots, but it will be painless. The discoloration will stay for a week or two and will go away on its own.
  • Diseased veins might feel tenderness after the procedure for a few weeks. Since veins are closed during the treatment, you may feel weak and tendered veins, but with time you will recover, and symptoms will go away.

If you feel any severe symptoms, inform your doctor immediately. The doctor will examine your condition and will recommend a solution accordingly.
