Basic repro. tract- LA Flashcards
Why do we castrate horses?
safety; not testicular cancer- so done at young age to prevent stallion behavior
- also less risk of neoplasia with cryptorchidism!
What spp do you NOT want to perform a standing neuter?
mules, donkeys, ponies & AMH
What is the most common approach to neuter, how & why?
Open approach- incision includes skin & vaginal tunic
that is done near the median raphie
- Closed approach only refers to initial skin incision (tunic is removed with testes)
Emasculator rule of thumb?
Nut to nut- so crushing portion is higher up than cutting portion
Aftercare- post NU?
Walk exercise ( reduces swelling), NSAIDs, ABX (rarely used)
What is evisceration?
surgical complication, where intestine/omentum does through vaginal ring than incision
Why should you not remove descended testicle only in a cryptorchid?
will look like a gelding & have unpredictable behavior
can look suspicious
What is the most common penile disease & what type of horse is it most common?
SCC & white horses!
neoplasia> trauma> penile paralysis
When would an episioplasty be warranted?
done to protect vulva & vagina
CS for episioplasty
CS: Pneumovagina, old age/ multiparous, poor perineal conformation, urine pooling & perineal injury
What causes rectovaginal laceration?
during parturition, foal will push through vaginal canal & rectum
- often unassisted birth & first foal
Rectovaginal laceration causes peritonitis! True/False?
False, b/c its outside the peritoneal cavity so NO health concern
- This is NOT an emergency repair; instead wait, keep clean + NSAIDs BUT no ABX.
CS of granulosa cell tumor?
CS: stallion-like, erratic, no estrus & infertility
Rectal: large ovary + small contralateral ovary (absent ovulation fossa)
TX: ovariohysterectomy (all approaches risk hemorrhage)
How long do you have to save the foal during a C-section?
90-120 min; problem with legs & necks being long
