We spoke to the highly-renowned and experienced vascular surgeon, Mr Muhammad Asad Rahi, who is fortunately continuing to see patients during these unprecedented times. We found out the answers to your FAQs regarding Clarivein, the latest advancement in treating varicose veins.


What're the main symptoms of varicose veins?

3 in 10 people are affected by varicose veins and they affect mainly women. There are symptoms which are related to these veins which are mainly the aching, pain, discomfort, heavy legs and unsightliness. There are more risks like skin changes, infection, inflammation and bleeding.


What is ClariVein?

Clarivein is a minimally invasive pain-free treatment for varicose veins. It is carried out as a walk-in walk-out treatment and is highly successful and is very safe. This technique is non-thermal, that means no energy is used to close the vein. It is considered safer and has no risks of nerve damage, and after the treatment, there are no pain killers required. It is also called a mechanical chemical-ablation (MOCA).


How does ClariVein work?

This procedure is carried out under a local anaesthetic and under ultrasound guidance. It involves using a special catheter with a rotating tip to cause a mechanical agitation to the vein's internal lining by targeting it, along with very precise delivery of the sclerosant drug and this does cause occlusion of the vein. Furthermore, there are no multiple injections required and there is no need for an injection of fluid around the vein. Therefore there is no internal leg pressure and this minimises the discomfort during the procedure. As it is non-thermal, there is less pain, no chance of nerve injury and also very little bruising.


What are the side effects of ClariVein?

This technique is very friendly, more comfortable and better tolerated by the patients. They can walk out of the hospital or clinic, resuming normal activities on the same day.


Is ClariVein painful?

Minimal discomfort for couple of days which improves with paracetamol.


What instructions should be followed after the procedure?

Due to the local anaesthetic used, it is recommended not to drive for 24 hours. I normally recommend to use travel stockings for a week afterwards that could minimise any minor complications.


How long does it take to see results?

The results are apparent within the first week.


So just to recap, what are the main benefits of 'Walk-in walk-out' treatment for varicose veins?

Clarivein is patient friendly, painless, much safer and more cost-effective for treatment of varicose veins. The technique also means that normal activity can be continued on the same day as it's non-thermal as well. It does no damage to nerves; these are the main unique advantages of this technique. Alternative treatments involving putting glue into the vein are costly and not applicable for all patients.
