What Are the Basics of Pulmonary Embolism?

What is the definition of pulmonary embolism?

Pulmonary embolism is a common illness that blood flow is blocked at a pulmonary artery. That means when a blood clot gets caught in one of the arteries going from the heart to the lungs, pulmonary embolism will occur.

Pulmonary embolism doesn’t have different stages or types. Either the disease happens, or it does not.

This blockage can cause serious problems, and even cause death.


What are the risk factors of pulmonary embolism?

More than 90% of cases of pulmonary emboli are complications of deep vein thrombosis (DVT), blood clots in the deep vein of the leg or pelvis, which typically occur in patients who have had orthopedic surgery and patients with cancer or other chronic illnesses like congestive heart failure.

The common risk factors or causes of pulmonary ambolism are:

  • A broken hip or leg
  • Stroke
  • Heart attack
  • Childbirth
  • Prolonged bed rest
  • Cancer
  • Certain congenital heart defects
  • Obesity
  • Chest trauma
  • Sickle cell anemia
