Which type of lung tumor gives a better prognosis:
1) undifferentiated
2) Well-differentiated
Well-differentiated (usually indicates a less aggressive tumor)
A paraneoplastic syndrome associated with primary lung tumors that can lead to lameness in dogs
secondary hypertrophic osteopathy
Most common location for lung tumor?
caudodorsal lung field
A paraneoplastic syndrome associated with primary lung tumors in cats
syndrome of multiple digital metastasis (swelling of several toes)
This tumor presents in young to middle aged dogs and will show basophilia and leukocytosis on labwork

Which component of thymic tissue usually becomes neoplastic
epithelial component

precaval syndrome (swollen head, neck, limbs)
& myasthenia gravis (secondary paraneoplastic syndrome)
This cancer is associated with older animals that have had asbestos exposure
Mesothelioma
Most common abnormality associated with BOAS
elongated soft palate
Surgical procedure indicated for elongated soft palate? Two techniques
Staphlectomy:
1) cut & sew
2) hot incision (less hemorrhage)
For which condition is there no treatment or cure because surgery is usually unrewarding
Laryngeal collapse
Laryngeal anatomy:
1) muscle that abducts arytenoids
2) innervation
1) cricoarytenoideus dorsalis
2) recurrent laryngeal nerve
Which surgical option for laryngeal paralysis is more technically difficult but offers a better overall opening of the laryngeal orifice and less potential for aspiration
Modified Castellated Laryngeofissure
What 4 classes of medications can be used in treatment of tracheal collapse
antitussives
bronchodilators
corticosteroids
+/- antibiotics
3 surgical options for tracheal collapse
dorsal tracheal membrane plication External prothesis internal support (stent)
Your selected tracheal stent should be _____% larger than the tracheal diameter
20%
T/F: After tracheostomy tube removal, the incision should be closed using a soft, absorbable suture
FALSE
allows second intention healing
