Q

signalment for urovagina

A

Q

treatment for 3rd degree perineal lacerations

A

complete disruption between rectum and vestibule. can lead to infertility

ALLOW 4 WEEKS TO PASS BEFORE REPAIRING

preop care: low bulk diet (if >1 yr post injury-> biopsies)

post op: keep feces sot for 3-4 weeks; sexual rest from natural breeding for 2 months; fertility returns 1 month post op

Q

treatment for 2nd degree perineal lacerations

A

same as 1st degree (mucosa of vestibule and skin at dorsal vulvar commisure) +constrictor vulvae muscle -> affects integrity of vestibular sphincter -> pneumo/urovagina

treatment: vestibulovulvoplasty

Q

you’re doing a standing laparoscopy to remove a granulosa cell tumor. what are your options for removing the tumor from the body wall?

A
  • morcellation/retrieval bag through portal
  • flank laparotomy if too big for portal
  • ventral midline laparotomy if EXTRA large

Q

how to close equine uterus

A

whip stitch (because equine uterus bleeds a TON) + simple continuous + inverting

17
Q

treatment for 1st degree perineal lacerations

A

torn mucosa of vestibule and skin at dorsal vulvar commisure

treatment options:

  • benign neglect
  • caslicks vulvoplasty
18
Q

diagnosis of granulosa theca cell tumor

A

transrectal palpation: enlarged ovary with contralateral small ovary

transrectal US: honeycomb ovary

hormone panel: AMH G.S.

histo

19
Q

how to do a c-section in mares

A

Ventral midline celiotomy

NEVER flank

20
Q

when can you use standing colpotomy to remove granulosa theca cell tumors?

A

G.S. is standing laparoscopy, but you can do standing colpotomy if tumor is <10 cm

21
Q

post op c-section in mares

A

oxytocin IV +/- drain

22
Q

3rd degree perineal laceration

A

complete disruption between rectum and vestibule. can lead to infertility

23
Q

indications for bilateral ovariectomy

A
  • behavioral issues
  • in embryo transfer recipient mares
  • jump mares (for semen collection)
24
Q

fertility post c section in mares

A

decreased

best to wait until FOLLOWING season

25
treatment for pendulous uterus in mares
standing laparoscopic uteropexy (shortens broad ligament/mesometrium)
26
G.S. treatment for granulosa theca cell tumor
standing laparoscopy (excellent visualization and hemostasis + decreased post op colic/pain) remove either via - morcellation/retrieval bag via portal - flank laparotomy if too big for portal - ventral midline laparotomy if EXTRA large
27
Barriers to infection in mare repro
- labia (with constrictor vulvae m) - vestibular sphincter - cervix
28
prognosis for surgical correction of pendulous uterus in mares
excellent; no complications reported
29
signalment for pendulous uterus in mares
multiparous mares
30
treament options for retrovestibular fistula
debridement and direct repair if >2 fingers in diameter -> can convert to 3rd degree laceration and closed
31
signalment for perineal lacerations/fistulas
PRIMIPAROUS Mares
32
cause of pendulous uterus in mares
same as pneumo/urovagina; poor perineal conformation/stretching -> inability to clear normal post mating endometritis -> decreased fertility
33
what causes perineal lacerations/fistulas
new mom has prominent vestibulovaginal sphincter and hymen remnants -> foal's foot catches on dorsal aspect of vestibulovaginal fold if noticed and corrected immediately -> forms rectovestibular fistula if not corrected -> perineal laceration
34
main risk with standing colpotomy to remove GT tumor
hemorrhage; also accidentally grabbing fecal ball (use US!!)
35
prognosis for c section in mares
better for mare than foal and depends on how quickly reach referral center.
36
where is the incision made for standing colpotomy
at 2 'oclock in the vagina
37
most common sign of granulosa cell tumor? what are some other signs?
anestrus also small contralateral ovary stallion like behavior nymphomania colic, hindlimb lameness (less common)
38
post op care after repair of 3rd degree perineal laceration
keep feces sot for 3-4 weeks; sexual rest from natural breeding for 2 months; fertility returns 1 month post op
39
where to make c section incision in mares
-start 10 cm caudal to umbilicus and extend 30-40 cm cranially
