Common Surgical procedures in SA Flashcards
(23 cards)
What are some indications for Ovariohysterectomy (OVHE)?
Elective sterilisation, Pyometra, ovarian cysts, Hydrometra/mucometra, Uterine torsion / uterine
prolapse, Uterine rupture, Ovarian / uterine neoplasia, Metritis, Improved control of diabetes mellitus / epilepsy
What is the NRCW classification for OVHE?
Clean/contaminated
What type of material should be used to ligate the ovarian pedicle in OVH?
Synthetic absorbable e.g. Vicryl (ideal)
In which situations would you not ligate the broad ligament? What should you ligate with?
Don’t ligate in very immature or small dogs/cats. Should be done using synthetic absorbable material e.g. Vicryl.
How can the cervical ligation be achieved? Which types of ligatures?
Can use encircling (mainly small), transfixing ligatures, or stick ties.
How can you check the right ovarian pedicle after OHE?
Elevate descending duodenum
How can you check the right broad ligament pedicle after OHE?
Elevate descending duodenum/move SI to left
How can you check the left ovarian pedicle after OHE?
Elevate descending colon (move medially)
How can you check the left broad ligament pedicle after OHE?
Elevate descending colon
What are some potential specific complications of OHE?
Ureteral injury, retained remnants, SMI, weight gain.
What are some anaesthetic considerations for C-sections?
Regurg/aspiration, depression of neonates, good analgesia for dam (avoid alpha-2, ketamine and thiobarbiturates), minimise time taken to remove.
What material should be used to suture the uterus after C-section? What types of patterns?
Synthetic absorbable (Monocryl ideal), simple appositional or inverting, single or double layer.
What is an En Bloc OVH?
Hysterectomy performed before a hysterotomy and before removal of neonates.
What are the disadv of an en bloc OVH?
All neonates need resusscitating at once.
What are the adv of an en bloc OVH?
Minimises anaesthesia time, minimal contamination, effective population control, no need for second surgery.
What are some indications for castration in SA?
Population control, behavioural control, behavioural modification, neoplasia, cryptorchidism, torsion, orchitis, trauma, anal adenoma (dog), perineal rupture (dog), prostatic disease.
What is the NRCW classification of castration?
Clean
What suture material is used in an open castration?
Synthetic absorbable material is best e.g. Vicryl. Can use encircling or transfixing.
What is the difference between open and closed castration?
Open: vaginal tunic cut and not repaired
Closed: vaginal tunic left intact
What are the pros of open castration?
Open castration may reduce post operative swelling and reduce the risk of ligature slippage
What are the pros of closed castration?
Closed castration reduces risk of intestinal herniation
What is scrotal ablation?
Removal of scrotum and testes
When is scrotal ablation indicated?
Scrotal disease eg MCT or trauma, Improved cosmesis and complications (bruising and swelling) in mature dogs, As part of scrotal / perineal urethrostomy procedure, When scrotum used as a skin donor site
