Spider Veins. Spider veins, or telangiectasias, are small, thin, blood vessels visible beneath the skin. They appear most commonly on the face and legs and may look like a series of lines, tree branches, or a spider-or web-like shape with a dark center.
Spider veins (referred to medically as telangectasias) and varicose veins are not the same -- and one does not lead to the other. Whereas varicose veins are large, swollen and occur singularly on the legs, spider veins are delicate and tend to develop in clusters. They are, however, caused by similar factors.ne theory is that spider veins, which occur near the surface of the skin, are fed by underlying varicose veins too small or embedded too deeply to reach the skin surface. These underlying veins disrupt circulation, causing spider veins to grow above them.
