1

Dorsally Displaced Soft Palate (DDSP): Type of Stridor

without distress

2

When is DDSP seen?

during exercise

3

DDSP: Signs

exercise intolerance, noise, expiratory component, cheek puffing

4

DDSP: Dx

signs, endoscopy

5

DDSP: Tx

treat concurrent dz, tongue tie, Cornell collar, sx - tie forward

6

Epiglotic Entrapment: Pathophysiology

aryepiglottic and subepiglottic tissue envelop epiglottis

7

Epiglotic Entrapment: Signs

exercise intolerance, inspiratory and expiratory noise, chronic cough

8

Epiglotic Entrapment: Dx

signs, endoscopy

9

Epiglotic Entrapment: Tx

Stall rest, sx - laser scalpel correction

10

Laryngeal Hemiplegia: Pathophysiology

paralysis +/ paresis of arytenoids from nerve irritation/inflammation

11

Laryngeal Hemiplegia: Signs

exercise intolerance, inspiratory noise (roar)

12

When is Laryngeal Hemiplegia seen?

during exercise

13

Laryngeal Hemiplegia: Dx

signs, endoscopy, electrolaryngeography

14

How is Laryngeal Hemiplegia graded?

range of motion of arytenoids

15

Laryngeal Hemiplegia: Grades

I/II - full abduction at rest and most of extercise
IIIA - abduction in exercise
IIIB - incomplete abduction
IIIC - severe collapse at exercise
IV - paralysis evident at rest

16

Laryngeal Hemiplegia: Tx

tie-back, ventriculectomy (reduces noise)

17

Stridor w/ Respiratory Distress: Etiologies

upper airway obstruction, tracheal collapse, pulmonary dz

18

Upper Airway Obstruction: Examples

strangles, bilateral laryngeal hemiplegia, lymphosarcoma, gutteral pouch tympany

19

Pulmonary Dz: Adult Examples

RAO, Acute viral pneumonia, interstitial pneumonia, diaphragmatic hernia, pneumothorax

20

Pulmonary Dz: Young Examples

Rhodococcus equi, interstitial pneumonia, acute viral respiratory dz

21

Acute Cough: Etiologies

equine influenza, equine herpesvirus, equine viral arteritis, trauma

22

Equine Influenza: Signalment/Environment

young, poor ventilation, crowded

23

Equine Influenza: Signs

pyrexia, lymphadenopathy, dry harsh non-productive cough

24

Equine Influenza: Sequelae/complications

purpura hemorrhagica (immune mediated vasculitis)

25

Equine Influenza: Tx

NSAIDs, rest (1wk/day of fever), ventilation

26

Equine Herpes Virus: Important Serotypes

EHV-1, EHV-2

27

EHV-1: Signs

cyclic fever spikes, depression, anorexia, abortion

28

EHV-1: Tx

NSAIDs, rest

29

EHV-2: Signs

respiratory dz in young horses

30

Equine Viral Arteritis: Pathogenesis

replication in bronchial macrophages
