Thread vein Sclerotherapy

Please be advised that this website contains graphic medical imagery

This treatment is rarely available on the NHS and is undertaken by several specialists including nurses and other therapists. It is wise to consult a vein specialist before undertaking any treatment. .


In general large varicose veins are treated first and the thread or spider veins are treated with a combination of sclerotherapy and skin laser.

Sclerotherapy  is used to treat reticular veins and larger thread veins. A sclerosing agent is injected into the vein via a very fine gauge needle. The resulting vein irritation causes it to occlude. Compression is then applied to the vein area with stockings or bandages  These stay on for 3 to 5 days depending on the size of the vein injected.
