Teat & Udder Surgery Flashcards
The Hugs teat tumor extractor is used for obstruction in the area of the __________
teat cistern
Identify this instrument:
Spiral teat curette
- Used if lichty teat knife doesn’t work
- Used to enlarge the teat canal
- Twist like a screw into teat canal then pull out quickly
Identify this instrument
Lichty teat knife
Used in a tight teat/streak canal to increase the diameter and increase milk flow
This instrument is useful for removal of a lactolith from a cow’s teat:
Alligator forceps
When are supernumerary teats typically removed?
~6 months of age (~the time the animal is vaccinated)
T/F: Operating through the papillary duct (teat canal) is less likely than thelotomy to result in a teat fistula
True
Which of the following teat lacerations has the best prognosis for uncomplicated healing?
- Vertical near the base of the teat
- Horizontal near the tip of the teat
- Vertical near the tip of the teat (papillary duct)
- Horizontal through the papillary duct
Vertical near the base of the teat
T/F: Operating through the papillary duct (teat canal) enables easier evaluation of obstructions within the teat cistern than theolotomy permits
False
For teat implants, the teat cistern is filled with __________
silastic tubing
Identify this instrument:
Hugs teat tumor extractor
- Used for obstruction in the area of the teat cistern
Identify this piece of equipment:
Larson Teat Canula
Placed in the teat canal to allow milk to exit the teat without milking (just unscrew the cap). This allows injuries of the teat to heal more rapidly. The disadvantage is that it predisposes the cow to infection
Name two instruments that can be used to treat obstructions in the teat cistern
Hugs teat tumor extractor, Cornell teat curette
What are the indications for teat implants?
- Teat cistern mucosa cannot be closed over the defect (mass/lesion)
- Membrane present in heifer between gland and teat cistern
“Thelium” is the proper term for __________
NIPPLE
T/F: Horizontal teat lacerations have a better prognosis than vertical teat lacerations
False
Vertical teat lacerations have a better prognosis
What is the #1 source of blood supply to the mammary gland that you’ll need to ligate in the case of udder amputation?
External pudendal artery and vein
largest vessels, use large suture (you can use umbilical tape) and double ligate (circumferential); if cut, there is really nothing you can do, animal bleeds to death (1.5 cm in diameter)
Can you use a teat implant in the case of teat laceration?
No.
T/F: Proximal teat lacerations typically heal more quickly than distal teat lacerations
True
More proximal = better blood supply
A cow presents with an emergency full-thickness teat laceration. How would you close it?
three-layer closure
- 1st – Mucosa (simple continuous pattern using tapered needle) - fine absorbable suture material (vicryl/PDS), 4-0 - mucosa & submucosa).
- Must use small suture so milk doesn’t leak & it’s TIGHT
- 2nd – Submucosa (simple continuous pattern using tapered needle & fine absorbable suture - muscle and submucosa)
- 3rd – Skin (vertical mattress using cutting needle and non-absorbable suture material)
What is the most common congenital anomaly in cattle?
supernumerary teats
Identify this instrument:
Cornell teat curette
When performing udder amputation, what suture pattern should be used for deeper tissue to relieve tension?
near-far-far-near
