Flashcards in Trachea Deck (17):
1

the trachea is easiest to assess on which view

lateral

2

thoracic trachea normally slightly on the right/left of mediastinum

right

exaggerated in obese and brachycephalic breeds

3

T/F in normal animals the diameter does not vary significantly during respiration

True

4

find the lesion

none- normal 

5

assess the radiograph

normal

trachea can be to the right

6

what can happen with extension of the neck

results in compression and narrowing of thoracic inlet

7

flexion of the neck can result in 

a bend at the cranial mediatinum 

false diagnosis of a cranial mediastinal mass

8

common lesions of the trachea

tracheal displacement - common

foreign body

tumor

hypoplasia

dynamic airway collapse - common

9

ventral deviation of cervical trachea

thyroid mass - most common 

retropharyngeal lymphomegaly

10

dorsal deviation of cranial mediastinal trachea

cranial mediastinal mass

neck position 

11

ventral deviation of cranial mediastinal trachea 

esophageal enlargement/mass

12

dorsal deviation of trachea at the carina

left atrial enlargement

generalized cardiomegaly 

13

ventral deviation of trachea at the carnia

tracheobronchial lymphomegaly

14

what dis?

tracheal hypoplasia

15

tracheal collapse 

dynamic in nature

diameter varies with respiratory cycle

toy breeds predisposed 

16

where is the dynamic narrowing occur during inspiration

cervical trachea

17

where does dynamic narrowing occur during expiration 

thoracic trachea
