AVDC Abbreviations
for use in Case Logs
Equine and Small Animal
This list of abbreviations has been recommended by the Nomenclature Committee and approved
by the AVDC Board. The list is in alphabetical order.
Anatomical items are show in black font.
Conditions and diagnostic procedures appropriate for use in the Diagnosis column of a case log
entry are shown in blue font.
Treatment procedure and related items suitable for inclusion in the Procedure column in the case
log entry are shown in red font.
Note: Use of other abbreviations in AVDC case logs is not permitted – write out the whole word
if it must be included in a case log entry.
For further information on the use of particular definitions, visit the Nomenclature page on the
