Spider veins stand for small, swollen veins which run directly in the skin. Their diameter differentiates between 0.5 and 2 mm, while the colour is sometimes red and sometimes blue. Spider veins are linked directly with the deep veins via the reticular veins. Spider veins are caused by the weakness of the connective tissue. This causes the reticular veins to expand. As a result, the venous blood flows through these veins slower and collects there. The venous accumulation is the cause for spider veins.

In most cases, spider veins are supplied by smaller varicose veins, which first have to be removed in a small outpatient operation, before the spider veins can be effectively treated.

After the removal of the smaller supply varicose veins, further treatment alternatives are possible:

They include:

• Thermo-coagulation of the spider veins
• Laser treatment of the spider veins
• Atrophy / sclerotherapy of spider veins
• Microfoam atrophy
• CLaCS - Cryo Laser Cryo Sclerotherapy

For the ideal success of treatment, an extensive examination of the vascular system is first necessary.
