Examples of thrombus in the following topics:

  • Cerebrovascular Accident

    • In thrombotic stroke a thrombus (blood clot) usually forms around atherosclerotic plaques.
    • A thrombus itself (even if non-occluding) can lead to an embolic stroke if the thrombus breaks off, at which point it is called an "embolus."
    • An embolus is most frequently a thrombus, but it can also be a number of other substances including fat (e.g., from bone marrow in a broken bone), air, cancer cells, or clumps of bacteria (usually from infectious endocarditis).
  • Clot Retraction and Repair
