Pulmonary Embolism - Causes

Pulmonary embolism refers to the obstruction of one or more pulmonary arteries by a thrombus (or thrombi) usually originating in the deep veins of the legs, the right side of the heart, or, rarely, an upper extremity, which becomes dislodged and is carried to the pulmonary vasculature.
