An embolism occurs when a clot moves through the bloodstream from the location where it was formed and becomes stuck in a blood vessel. An embolus, can be a blood clot, air bubble, or piece of fat, bone marrow, or tumor tissue.
The embolus in a pulmonary embolism is usually a blood clot. A blood clot that forms and remains in a vein is called a thrombus. It most often starts in a vein in the legs or pelvis.
These factors increase your chance of developing pulmonary embolism. Tell your doctor if you have any of these risk factors:
- Blood clot in a deep vein of a leg or pelvis
- Increased levels of clotting factors in the blood. Usually caused by cancer (eg, pancreatic)
- Prolonged bed rest, such as during a serious illness
- Major surgery, especially after pelvic surgery, knee replacement, or heart surgery
- Injury to a vein in a leg or pelvis
- Fractures of the hip or thigh bone (femur)
- Heart attack , stroke
- Certain blood disorders
- Prolonged sitting, such as during a long trip
- Birth control pills
