Inflammatory, non-atherosclerotic (autoimmunological?), segmental, mostly obliterating panarteritis of the small and medium-sized arteries and veins, affecting mainly young male smokers. It should be discussed clinically if the disease begins before the age of 40, if the distal arteries (lower limb, hand and foot) are selectively affected and if thrombophlebitis saltans is present.
The clinical picture is discussed further in this encyclopedia under thrombangiitis obliterans.
