What is a reticular vein?
A reticular vein is a dilated bluish intradermal vein, usually from 1 mm in diameter to less than 3 mm in diameter. Reticular veins are also known as blue veins. In the classification of veins, reticular veins are considered type III veins. Telangiectasias (type I veins) can result from refluxing reticular veins. When such reticular veins are associated with telangiectasias, they are called “feeder veins”.
