may cause damage to the cells of
internal or external tissues
and the consequent degeneration of these tissues.
- Internally, ingested materials may cause pressure
at any level from the mouth through the digestive tract, although the oesophagus
is probably the structure most commonly affected.
- Externally, pressure necrosis may be seen over thinly-covered bony prominences,
particularly if in constant contact with hard external surfaces (e.g. substrate).
- Thin/narrow bands such as line or plastic rings caught about the body or a limb
and pulled tight may cause pressure necrosis through constriction.
