Aspiration in autopsy

Author: Mikael Häggström [note 1]
In case material is found in the trachea or bronchi in lung autopsy:

During autopsy

  1. Compare the material to what is found in the ventricle, suggesting aspiration.
  2. Check if the linings of the trachea and bronchi is inflamed. Non-inflamed linings suggests postmortem aspiration.

Microscopic evaluation

Foreign material in bronchioles but not in alveoli in a patient who has received CPR suggests a post-CRP finding rather than a primary cause of death.

Microscopy report


Histopathology of aspiration
In bronchioles there are plant-like cells together with fragments of respiratory epithelium, but alveoli are clear, indicating a post-CPR finding.
