Sample item

When can an intravascular thrombus be classified as an embolus?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. After it detaches and travels to a distant vessel

A thrombus becomes an embolus only after part or all of it detaches, travels through the circulation, and lodges in a downstream vessel.

Option by option

  • A. After it detaches and travels to a distant vessel (correct)

    Correct: detachment and travel convert thrombus into thromboembolus.

  • B. When it is organized into a fibrous scar in situ

    Organisation occurs at the original site and does not imply embolization.

  • C. When it causes chronic venous valve reflux locally

    Valve reflux is a local venous consequence, not embolic migration.

  • D. While it remains attached at its original site

    An attached clot is a thrombus, not an embolus.
