Tunica Vaginalis
Encircling suture.
Vicryl
How is the feline scrotum prepared for castration?

Which testicle should be removed first in a feline castration?
Lower Testicle
Which 4 layers are incised in the feline castration?
Skin

Tunica Vaginalis
Exteriorising the feline testicle during castration allows for visualisation of which structures?
Blood Vessels
Ductus Deferens
Following exteriorisation of the feline testicle, how is the castration performed?
D. Def separated from testicle and ties to testicular BVs.
Cut all 4mm distal to knot
What suturing should be performed on a feline castrate?
None
What are the indications for ovariohyterectomy?

What are the benefits of OVH prior to the first season?
reduced risk of mammary neoplasia
BVs smaller
Reduced anaesthetic time

Why should neutering not be done when a bitch is in season?

After the Skin and SQ, what must be incised in a feline midline OVH?
Linea Alba
How is the right uterine horn located in a midline OVH?
finger down body wall, distal to kidney
Once the ovary is exteriorised (MOHV), what must be clamped?

Once the Proper ligament is clamped in an MOVH, what must be broken with fingers?
Suspensory ligament
MOVH: where should the window in the mesovarium be made?
Caudal to the ovarian vessels.
MOVH: Which technique is used to prime the ovarian pedicle for ligation?
Triple Clamp Technique
MOVH: where should the pedicle be incised?
