In PVD the blood vessels narrow. Narrowing is normally caused by arteriosclerosis. This is a condition when plaque builds up inside a vessel, plaque decreases the amount of blood going to the organs, and therefore decreases the amount of oxygen that reaches the cells. As the narrowing progresses, clots may develop and that would restrict the blood movement even more. Soon afterwards the vessel can become obstructed.
