What causes pulmonary embolism?
Most cases of pulmonary embolism are caused by deep vein thrombosis, in which a blood clot in the leg has dislodged and travelled through the bloodstream to block a vessel in the lung. Other less common causes include an air bubble in a vein, bone and fat fragments from a fracture that have found their way into the bloodstream, a cancerous tumor that has broken away from a larger tumor, or amniotic fluid from pregnancy.
