LA Soft Tissue Case Studies (23) Flashcards
Dr. Devine
What procedure can be done to help this horse in the short term?
cystotomy
perineal urethrotomy
What is a perineal urethrotomy?
a surgical procedure that creates a new opening in the urethra, the tube that carries urine from the bladder to the outside of the body
temporary or permanent
can place a catheter through the PU incision to help divert urine
What is the most common type of equine urolith/cystolith?
calcium carbonate
What diagnostics should be done prior to surgery for cystic calculi in a horse?
chemistry panel
endoscopy of the urinary bladder
US of kidneys
rectal exam
What are the types of stones in small ruminants on a grain diet?
calcium phosphate (apatite)
struvite
What are the types of stones in small ruminants on a legume diet?
calcium carbonate
A pigmy goat is straining to urinate, and radiographs reveal stones. What surgical procedure would you recommend first?
urethral process amputation
infuse the urethral opening with lidocaine, cut off urethral process with scissors
What do you do if urethral process amputation doesn’t get rid of the stones?
tube cystotomy
perineal urethrotomy +/- penile amputation
bladder marsupialization
A horse presents with hypovolemic shock. What do you grab to rapidly expand the volume?
hypertonic saline - first
lactated ringers
How do you help a patient with hypovolemic shock?
give small volume (1-2 L) of hypertonic saline, colloids
followed by large volume of isotonic crystalloid like LRS
Where do you incise the abdomen for a horse exploratory?
ventral midline
What is the star?
pelvic flexure
What classification of surgery is a pelvic flexure enterotomy?
clean-contaminated
Give an example of a “clean” surgery
arthroscopy
Which arytenoid is abnormal?
left
What do you think the primary clinical sign is associated with this lesion?
inspiratory noise
Which nerve is abnormal in a horse with this lesion?
left recurrent laryngeal
What are the clinical signs of left laryngeal hemiplegia?
loud inspiratory noise
arytenoid cartilage partially occludes the airway
What is treatment for left laryngeal hemiplegia?
tie back surgery with nonabsorbable suture - suture prosthesis to pull the arytenoid back toward the cricoid
What approach do you want to use to access the uterus in a cow?
left flank
What suture pattern do you use to close the uterus?
Utrecht
What suture pattern would you use to close the muscles of the body wall?
simple continuous
cruciate
What type of suture would you use to close the muscles of the body wall?
absorbable monofilament
absorbable multifilament
What type of suture would you use to close the skin on a bovine flank celiotomy?
nonabsorbable multifilament
What suture pattern would you choose for the closure of the skin incision in a bovine c-section?
ford interlocking
