Spider Veins – What Are They?

Spider veins, also known, as telangiectasias are small, dilated blood vessels that appear near the surface of the skin. Spider veins tend to be red or blue in color, and can be painful, itchy, and potentially bleed.

Spider veins are generally caused by an increase in pressure in veins close to the skin from increased pressure in the deeper veins. The deeper veins may include veins in the reticular dermis (reticular) or underlying pathology in the superficial or deep system. In some cases an ultrasound (US) needs to be done to determine if there is an origin.
