This week there was an article in the Daily Mail about a new catheter based
sclerotherapy technique for varicose vein treatments called "
Clarivein".
We have had many people contacting us at The Whiteley Clinic asking if we recommend this technique, how it works and if we provide
Clarivein for the treatment of varicose veins.
From the information available from the company, a study in the USA has shown that treated veins are "occluded" in 29 of 30 people treated in the short term. However there is no information as to whether this "occlusion" is just due to the veins having blood clots in it, or if it has been successfully closed by destroying the wall.
Research and experience on
sclerotherapy in big veins shows that big veins treated with
sclerotherapy often appear "occluded" in the short term, but the clots dissolve over several months meaning that the veins open up again and the varicose veins return.
The
Clarivein technique is
sclerotherapy but it also adds a catheter that rotates, spreading the
sclerotherapy inside the vein and maybe damaging the wall. This might improve the expected results from this
technique - however there is no evidence available at the moment that the vein wall is damaged enough to cause a permanent closure of the vein.
EVLA (Laser) and
Radiofrequency Ablation (
RFiTT and
VNUS) - when used correctly under local anaesthetic - have all been shown to close the vein wall permanently without causing clot in the vein - giving excellent long term results. Hence we offer all f these techniques to suitable
patients.
As a specialist clinic we are committed to only offering our patients treatments that our experts are convinced give the best possible results - either by studying our own research or studying the research performed by others.
At the time of writing this, and on the information provided to date, we are not happy to offer
Clarivein to our patients unless as part of a study. We have asked the distributor of
Clarivein in the UK to provide answers to questions which would allow us to be able to assess whether this technique is likely to have good long-term outcomes. Unfortunately, although we have had replies, we have not had answers to the questions that we have posed.
Therefore at the moment, although
Clarivein is clearly a novel idea, our experts have some concerns as to the long-term efficacy of
sclerotherapy treatments in large veins and therefore we need have several scientific questions answered before we will be happy to offer its to our patients.
If we would receive any further information to answer questions, or if we start any research of our own into this product, this will be announced on our website and on this blog.
