Embolism is the occlusion of an artery or capillary by some substance brought to the spot from some other part of the body in the blood stream.

Pulmonary embolism occurs when a pulmonary artery becomes occluded by an embolic thrombus derived from deep leg vein thrombosis.

Emboli to the brain can come from the heart or from the arteries.

Embolic material tends to lodge at arterial or arteriolar bifurcations, and the size of the embolic particle determines the site where initial lodging takes place.

Pulmonary embolism is an extremely common condition and an important cause of sudden death.
