What is reticular vein ?
A reticular vein is a dilated bluish intradermal vein, usually from 1 mm in diameter to less than 3 mm in diameter. They are usually tortuous. Reticular veins are also known as blue veins, intradermal varices and venulectasias.
These reticular veins are the underlying cause to spider veins, and therefore, need to be treated along with the spider veins to reduce the likelihood of recurrence of the spider veins.
Note - spider veins are smaller than reticular veins.
