Where to aim radiograph for empyema diagnosis?
Edge of the vertical ramus of the mandible
Tx for empyema?
1.
2.
- Indwelling catheter
2. Sx (same four approaches as for Tympany)
Main sign of guttural pouch mycosis?
Epistaxis. Waxing and waning, over times becomes progressively more severe
A common clinical sign of guttural pouch mycosis other than epistaxis? What causes it?
Dysphagia
Damage to pharyngeal branches of vagus and glossopharyngeal nerve leads to recurrent laryngeal hemiplagia
Way to diagnose guttural pouch mycosis via endoscopy?
Find the fungus growing on ceiling of guttural pouch
Tx for acute case of bleeding for guttural pouch mycosis
Blood transfusion
IV Fluids
Pathway for the vessels affected by guttural pouch mycosis.
Common carotid —> _____ —> _____ —-> ______
Which one is affected by the fungus?
- Occipital –> internal carotid
- External carotid
- Internal carotid
Tx of Guttural pouch mycosis:
- 2.
- Carotid angiogram
2. Arterial ligation
Options for Arterial ligation for tx of guttural pouch mycosis:
1.
2.
3.
- Internal carotid artery ligation
- External cartoid artery ligation
- Balloon catheter occlusion
What vessels gets a catheter inserted into it for an angiogram to dx guttural pouch mycosis?
common carotid artery
Why do inject contrast fluid for angiogram to dx guttural pouch mycosis?
because the occiptal, internal carotid, and external cartoid all branch off differently in every horses..
2nd incision for tx of guttural pouch mycosis should be where? What do you do at this incision site?
- close to the branches of the internal / external cartoid arteries branch
- Insert balloon catheter into internal carotid artery.
What is the goal of using a balloon catheter to treat guttural pouch mycosis?
stop blood flow to the fungus.
What is a strange side effect of balloon catheterization as treatment for guttural pouch mycosis
Blindness
