Appearance of Spider Veins
Tiny purple and red blood vessels in the outer layer of skin are known as spider veins or telangiectasias.
They can appear anywhere on the leg and may be small or gathered densely in clusters. A bit deeper in the skin are somewhat larger reticular veins. They are blue in color and are often the feeder source to the spider veins and can be unsightly in appearance and may cause discomfort in the skin.
Patients often say that the number of spider veins they have seem to increase in the winter. They don’t actually increase in number, but in the fall and winter, our tans have faded so the spider veins may be more obvious, making us less comfortable with the cosmetic appearance.
Spider veins are primarily caused by genetic inheritance. However, an underlying venous insufficiency problem may be associated and should be treated first. Correcting the cause reduces the chance of spider vein recurrence at a later date.
