The Vein Institute


What is ClariVein?

ClariVein® is a non-surgical treatment for varicose veins. It uses a special thin infusion catheter with a wire tip that rotates 360 degrees to deliver sclerosant directly into the vein wall. 

Due to ClariVein’s small size and flexibility, our specialists can insert it into your vein through a single, pin-sized entry point. On top of that, ClariVein doesn’t require general anaesthesia. Hence, you can enjoy a comfortable walk-in and walk-out treatment and get back to your regular activities after leaving our clinic.

What happens during the procedure?

  • Your doctor will inject a local anaesthetic into your leg.
  • They will then make a tiny incision and feed the catheter through and into your vein.
  • Following that, they’ll activate ClariVein’s wire. It will rotate while injecting sclerosant directly into the walls of the problem vein. This process will agitate the vein walls, causing them to collapse and seal shut.
  • Once your doctor seals the vein, they will pull the catheter out and bandage the incision point. Your body will then start absorbing the vein and rerouting blood flow.

What are the benefits of ClariVein?

  • You get a comfortable treatment. Though the process can sound intimidating, it is relatively painless. In fact, ClariVein usually causes less discomfort than thermal ablation both during and after the treatment.
  • Pin-sized entry point. No large incisions, sutures, or stitches
  • Only requires local anaesthetic. In some cases, even this may not be necessary.
  • After treatment, you can return to your regular activities.
  • Compared to thermal ablation procedures, ClariVein carries no risk of thermal damage, reduced risk of bruising, and typically causes less discomfort during and after the treatment.

What are the risks of ClariVein?

ClariVein is a low-risk varicose vein treatment. However, it can cause bruising and temporary numbness in the lower leg. As it involves injecting an irritant directly into the vein, it’s also possible for your body to have an adverse reaction to the solution – though we will do what we can to avoid it.

Is ClariVein right for me?

ClariVein can be a great treatment option if your varicose veins are medium-sized and if you’re unlikely to adversely react to the sclerosant. Before your treatment, we will conduct an allergent test and an ultrasound scan of your veins to see if ClariVein is suitable, or if an alternative treatment would be better.

At The Vein Institute, we pride ourselves on delivering the best results and the highest quality of care for our patients. We will tailor your treatment plans to your needs.

So, if you’re wondering whether ClariVein is right for you, don’t hesitate to ask your doctor during your consultation.
