embolism

n. blockage of an artery or vein by a blood clot or other undissolved matter (Medicine)

In medicine, an embolism occurs when an object (the embolus, plural emboli) migrates from one part of the body (through circulation) and cause(s) a blockage (occlusion) of a blood vessel in another part of the body. The term was coined in 1848 by Rudolph Carl Virchow.This can be contrasted with a "thrombus" which is the formation of a clot within a blood vessel, rather than being carried from somewhere else. Thrombus mainly form in the Arteries whereas Emboli form in the Veins.Blood clots form the most common embolic material by far: other possible embolic materials include fat globules (a fat embolism), air bubbles (an air embolism), talc embolism (often following drug abuse), septic emboli (containing pus and bacteria), or amniotic fluid.
