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

Life Threatening Causes

Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated. Pulmonary embolism is a life-threatening condition and must be treated as such irrespective of the underlying cause.

Common 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.
  • Deep vein thrombosis

• Non-thrombotic causes of PE are:
  • Cancer
  • Fat
  • Infection
  • Amniotic fluid
