Overview
Pulmonary embolism (PE) is the acute obstruction of the pulmonary artery or one of its branches by a thrombus, air, tumor, or fat. Most often, PE is due to a venous thrombus which has been dislodged from its site of formation in the deep veins of the lower extremities, a process referred to as venous thromboembolism.
Causes
- The most common cause of PE is a venous thrombus which has been dislodged from its site of formation in the deep veins of the lower extremities.
- Non thrombotic causes of PE are:
- Cancer
- Fat
- Infective agents
- Amniotic fluid
