What Researchers Did
This review article looked at how tiny particles or bubbles that get into the bloodstream (microemboli) can affect the brain and spinal cord.
What They Found
This is a conceptual review, not an experimental study, and it describes a proposed injury process rather than reporting new data or statistics. It explains that small emboli, such as fat particles, can escape filtering by the lungs and reach brain tissue that already runs on a low oxygen supply. According to the review, when embolic events further reduce oxygen in this tissue, it can lead to blood-brain barrier dysfunction, inflammation, and demyelination. The abstract does not report sample sizes, patient outcomes, or treatment results.
Canadian Relevance

Study Limitations
This is a narrative review reflecting one author's synthesis of existing evidence rather than a controlled experimental study, so it does not provide original data to confirm the proposed injury mechanism.
