Spider veins: Also known as telangiectasias, are damaged veins. We develop varicose veins when tiny, one-way valves inside the veins weaken, and some blood flows backward and accumulates in the vein. Extra blood in the vein puts pressure on the walls of the vein. With continual pressure, the vein walls weaken and bulge. In time, we see a varicose or spider vein.
