Pulmonary embolism is the sudden blockage of a major blood vessel (artery) in the lung, usually by a blood clot . In most cases, the clots are small and are not deadly, but they can damage the lung. But if the clot is large and stops blood flow to the lung, it can be deadly.
A blood clot that travels to the lung can lead to a pulmonary embolism, permanent lung damage, and even sudden death. A blood clot that travels to the brain can cause a stroke. A blood clot that forms within the arteries of the heart can cause a heart attack. Your risk of developing blood clots can be minimized by making certain lifestyle changes and following your doctorâs treatment plan.
