There are two types of blood vessels; arteries and veins. Arteries carry blood under high pressure out to all areas of the body after being pumped by the heart. Veins carry blood that should be under low pressure, back to the heart. An artery does not usually connect directly to a vein. Usually there are very small vessels called capillaries that connect an artery to a vein.

Patients also start to develop small red spots, or telangiectasia’s on the face, mouth, fingers, and in the gastrointestinal tract.
