Lymphoma
Majority of primary lung tumors are? (type)
Carcinomas (adenocarcinomas)
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
Canine pulmonary lymphomatoid granulomatosis
Which component of thymic tissue usually becomes neoplastic
epithelial component
Aside from respiratory distress, what are two other clinical signs associated with a Thymoma
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
Most common neoplasia of trachea?
Chrondromas/chrondrosarcomas
Best surgical option for treatment of tracheal neoplasia or trauma
Tracheal resection
When anastomosing the trachea, which aspect should be sutured first?
Dorsal aspect
What are the two options for tracheal resection and which is preferred?
Splint ring (preferred)
Annular ring anastomosis
What type of suture is best for tracheal anastomosis
monofilament, non-absorbable
Leakage of a ______ _____ results in a chronic, persistent pneumothorax
pulmonary bullae
Which hernia type is typically congenital?
Pericardioperitoneal (incomplete separation of pericardium and diaphragm)
Which hernia type is most commonly associated with trauma
pleuroperitoneal
T/F: Diaphragmatic hernias have unique clinical signs and can be ruled out on clinical presentation alone
FALSE
Best suture choice for correction of a DH?
long lasting, monofilament
Can be absorbable (PDS II)
Can be non-absorbable (Nylon)
