Peripheral arterial disease refers to the narrowing of arteries outside the heart and brain, usually as the result of atherosclerosis or ‘hardening of the arteries’ (a build up of fatty deposits on the inner wall of arteries). When the arteries become narrowed, the flow of blood to the target organs or tissues is reduced.

The arteries commonly affected are those carrying blood to the kidneys, intestines, arms and legs, and the carotid arteries as above. Peripheral arterial disease is common in your legs and may present with a dull, cramping leg pain that occurs when you walk or run but stops when you stand still. This is known as ‘intermittent claudication’.

Treatment for peripheral arterial disease may involve medication and/or surgery.
