You have been asked to attend Ambulatory Emergency Care (AEC) because it is suspected you may have a blockage in a blood vessel in your lungs called a pulmonary embolism (PE).This leaflet contains some information about what this means and how you will be looked after.

A PE is when a small blood clot travels into a blood vessel in your lungs. This clot usually comes from a blood clot in your leg called a Deep Vein Thrombosis (DVT). The clot can break away and travels through the body.

Once the clot reaches the lungs, the vessels in the lungs start to get smaller. The lungs are full of very small blood vessels which are easily blocked when the clot becomes wedged. The clot may prevent blood travelling to that section of the lung.
