1

Banding techniques are assoc. with less ___pain but more ___ pain

less acute pain
more chronic pain

2

Which emasculator tool can be used to disrupt blood supply to testicles WITHOUT creating an open skin incision

Burdizzo emasculatome

3

The highest risk for tetanus is assoc. with which castration method?

Banding techniques

*except when used in 1-2d old calves

4

Which spp. has a higher incidence of inguinal herniation?

Pigs

5

In which spp. should tetanus prophylaxis ALWAYS be given for castration procedures

Goats and horses

6

Describe how Deslorelin works for chemical castration and in which spp. is it typically used?

it's GnRH super agonist--> causes an LH surge which upregulates testosterone production--> T4 is so high, its receptors become downregulated

*Swine (boar)

7

Why should castration of camelids be delayed until after puberty?

have an increased risk of physeal fractures if done too early

8

What recommendation do you need to make the owner after you diagnose a bull with persistent frenulum

this is a heritable condition so you should NOT breed this bull for seed stock

*can use as terminal sire

9

Majority of preputial lacerations occur during? On which surface of the prepuce do they occur?

Breeding

ventral surface

10

The most likely sequela of preputial laceration in:
1) bos indicus
2) bos tarus

1) preputial prolapse

2) abscess (sheath swelling)

11

Your top differential if the prepucial swelling is:
1) unilateral
2) bilateral

1) retropreputial abscess

2) hematoma

12

In what location does the penis almost always rupture in cattle?

dorsal aspect of the distal bend of sigmoid flexure

13

What is a common physical exam finding that should make you suspect a penile hematoma/rupture

inability to palpate sigmoid flexure

14

Which type of inguinal hernia is a surgical emergency in cattle?

Acquired, direct

15

Most common side for acquired, indirect inguinal hernias to occur on (cattle)

LEFT

16

In cattle, acquired direct hernias are assoc. with? And why is it a surgical emergency?

trauma;

risk for incarcerated bowel is very high

17

Because congenital inguinal hernias are heritable, repair is accompanied by?

bilateral castration

18

Describe the difference between direct and indirect hernias in DOGS

indirect--abdominal contents pass through vaginal process

Direct--contents are in separate peritoneal outpouching and adjacent to vaginal process (not in it)

19

Which type of tranquilizers should be avoided in stallions?

phenothiazine derivatives (Ace)

20

Generalized swelling/cellulitis of equine penis is the major cause of which condition

Paraphimosis

21

Define phimosis

inability to protrude penis

22

Priapsim is defined as?

persistent erection--penis fails to detumesce

23

Most common intersex condition in equine males

male pseudohermaphrodite

24

A segmental posthetomy is best for lesions located where?

on prepucial fold

25

Which surgical technique can be used for tx of paraphimosis in GELDINGS only

Bolz technique Phallopexy

26

The main goal with partial phallectomy (no matter the technique)

create a new urethral opening and amputate penis distal to new opening

27

The main difference between the Vinsot's and Williams partial phallectomy techniques is?

Orientation of urethral incision

Vinsot--triangle base is proximal

williams--triangle's base in distal

28

What two structures are connection together by:
1) ligament of tail of epididymis
2) proper ligament of testis

1) tail of epidid to parietal vaginal tunic

2) tail of epidid to testis

29

How can early castration impact appearance of the horse?

physes will close later--> longer legs

30

When using an emasculatome is important to make sure the crushing jaws are placed _____ and the blade is placed _____

jaws= proximal

blade= distal

31

Open castration technique may predispose to which two post-op complications

1) Septic funiculitis (infection of spermatic cord)

2) hydrocele/vaginocele

32

Though left and right testicles are retained with equal frequency, the left is more likely to be located where? The right?

Left--abdominally retained

Right--inguinally retained

33

The following parts of the gubernaculum turn into which testicular structures
1) cranial part
2) middle part
3) caudal part

1) proper ligament of testis

2) ligament of tail of epidid

3) scrotal ligament

34

When pulling a retained testis through the vaginal ring, traction should be applied to which structure

PLT

35

On closure of the flank approach for cryptorchidectomy, which layers is it not necessary to close (2)

peritoneum
transversus abdominus

36

The caslick's vulvoplasty is most common used to correct which condition in mares?

What are two other sx repair options for this condition?

Pneumovagina

1) perineal body reconstruction
2) perineal body transection

37

Which surgical technique for correction of urovagina is only indicated for mild, transient cases of VVR?

Caudal relocation of transverse fold

38

Surgical repair of which type of foaling injury MUST be delayed?

Perineal lacerations

39

An important pre-op preparation for mares who will undergo perineal laceration repair

laxatives! (or some other way to make feces soft)

40

Which surgical repair techinique is best for
1) caudally located RV fistulas
2) for deeper (more cranial) RV fistulas
