Pulmonary embolism, abbreviated PE, is often on the differential in autopsies, as it is not easy to diagnose clinically.

Pulmonary embolism is a non-specific term it may refer to a number of things, including:

  • Pulmonary venous thromboembolism.
  • Pulmonary fat embolism.
  • Pulmonary foreign body embolism.
  • Pulmonary septic embolism.

PE usually refers to pulmonary venous thromboembolism, abbreviated VTE, if not otherwise specified.

Clinical

  • Shortness of breath (dyspnea) - classic symptom.
  • Tachycardia.
  • Chest pain.
  • Findings associated with deep vein thrombosis
    • Leg pain.
    • Leg swelling.

Notes:

  • Venous thrombosis OR~=12 for PE.[1]

Risks factors (VTE)

  • Trauma.
  • Immobility.
  • Pregnancy.
  • Medications (e.g. OCPs).
  • Hypercoagulable states (memory device CALMSHAPES):[2]
    • Protein C deficiency.
    • Antiphospholipid antibody syndrome (APLA).
    • Leiden factor V deficiency.
    • Malignancy.
    • Protein S deficiency.
    • Homocystinemia.
    • Antithrombin deficiency.
    • Prothrombin G20210A.
    • Excess factor VIII.
    • Sticky platelet syndrome.

Gross (VTE)

  • Intravascular spagetti with cream sauce.
  • Leg swelling.

Microscopic (VTE)

Features:

  • Organized blood components (RBCs, WBCs) in layers with organization (fibrin); Lines of Zahn = layers of components
