Microsclerotherapy is used to treat thread veins, and is by far the most common and most effective form of treatment.

Some clinics will offer treatment of thread veins using laser or IPL. Although this can be quite effective with thread veins on the face, it is usually both painful and ineffective with thread veins on the legs.

What is microsclerotherapy?

Microsclerotherapy uses the same chemical that is used for foam sclerotherapy but a much more dilute solution, and is used in liquid form rather than mixed with air into a foam.

It is important, even with thread veins, to discover if there is an underlying cause for these, and this will need to be established prior to the microsclerotherapy being undertaken. Usually, this will be small reticular veins that are feeding the thread veins, which would require foam sclerotherapy. Very occasionally, there is a more extensive source of increased pressure, which would require endovenous laser ablation (EVLA).


The procedure

A tiny needle is used to inject the liquid into each cluster of thread veins. As with foam sclerotherapy, there is a maximum dose permitted for each patient. As such, if there are extensive thread veins, it may well be impossible to inject all of these during one session.

After the injections have been completed, a stocking is applied to each leg, and you must wear these for one whole week.


Effective treatment for thread veins

Thread veins are paradoxically more difficult to treat than larger varicose veins.

It is normal to require more than 1 session of injections, so it is important to note that it might take some time to fully resolve all of your thread veins.

Most patients require between 2 and 4 sessions. Occasionally, only 1 session is required. At the other extreme, we have had one patient with extremely extensive thread veins covering almost every square inch of her legs, who required more than 30 sessions – but she was still completely delighted with the final results.
