Sharp transection of the suspensory ligament as an alternative to digital strumming during canine OHE

- diff in peak HR?
- diff in complications or pain?
Total sx time 1.1 min faster for ST than DS
Digital strumming had 30-fold greater odds taking > 1 min vs ST
HR from baseline to peak was 7.4 bpm lower in ST group than DS group
No complications, no difference in pain postop between groups

Pedicle drop or tear occurred in 0.3% of cats (84% did not result in hemorrhage)
0.12% cats had pedicle-related hemorrhage (All corrected intraoperatively without serious complications)
Fudge JFMS 2021
Blood loss and coagulation profile in pregnant and non-pregnant queens undergoing elective ovariohysterectomy
- compare blood loss
- Conclusion about pregnant cats
Median blood loss was greater for pregnant cats (2.0ml) than non-pregnant cats (<0.5ml)
Pregnant cats relatively hypercoagulable
Bailin JFMS 2022
Retrospective evaluation of feline dystocia: clinicopathologic findings and neonatal outcomes in 35 cases (2009-2020)
- cause of dystocia
- calcium/glucose?
- % success medical management?
- maternal survival? kitten survival?
Dystocia was attributed to maternal factors in 69% (n=24) and fetal factors in 31% (n=11).
No queens in stage 2 labor were hypocalcemic or hypoglycemic
Medical management successful in 29%
Maternal survival 94%
Overall kitten survival rate 66%

Healthy nonobese bitches maintain acceptable spontaneous ventilation during laparoscopic ovariectomies
- insufflation pressure?
- % patients didn’t
require ventilation? - what was trend of etCO2?
Abdominal insufflation 10mmHg. Significant temporal changes were detected in all recorded parameters.
Twenty of 21 dogs (95%) maintained etCO2 within tolerance via a mild increase in RR and did not require assisted ventilation.
Following insufflation, there was a tendency toward inadequate ventilation over time characterized by increased etCO2 .
Guest JAVMA 2023
Performing an ovariohysterectomy at the time of c-section does not pose an increase in risk of mortality, intra- or postoperative complications, or decreased mothering ability of the bitch
- difference in complications?
- which procedure had longer sx time and longer time to nursing?
80 bitches undergoing C-Section and 45 bitches undergoing CSOVH
There was no difference in anesthesia duration, intraoperative complications, postoperative complications, mothering ability, puppy survival to weaning, or other variables compared between groups.
CSOVH bitches had longer surgery times and longer time from delivery to nursing
Adams VSURG 2022
Risk factors for neonatal mortality prior to hospital discharge in brachycephalic and nonbrachycephalic dogs undergoing cesarean section
- % survival to discharge?
- 2 factors puppies more likely to survive?
Overall neonatal survival to discharge was 93%. Survival was similar between brachycephalic & nonbrachycephalic breeds
Puppies delivered via elective c-section were more likely to survive compared to emergency c-section
Puppies delivered in larger c-section litters were more likely to survive compared to smaller litters
Flock JFMS 2022
Anti-Müllerian hormone as a diagnostic tool to identify queens with ovarian remnant syndrome
- compare AMH ORS, intact, spayed
- with mildly elevated AMH, what was elevated?
- continued heat after sx?
In 15 cats with ORS, the AMH serum concentrations were significantly higher than in spayed cats and significantly lower than in sexually intact cats.
The cat with the lowest AMH serum concentration had a simultaneous high progesterone serum concentration.
Cats with ORS did not show any heat signs after surgical removal of the ovarian tissue

- complications?
- suggested weight and age?
Time required to complete TLOVE (34.3 min) was longer than LapOVE (22.3 min)
Intraop complications in 3/60 dogs (5%) undergoing TLOVE & 0/202 in Lap OVE group
Suggested weight 10-33 kg and age 6-13 mo
Charlesworth JSAP 2019

- % complications open (list complications)
- % complications lap (list)
46/106 (44%) dogs with open got a complication
- 30 dogs (28.3%) wound healing issues, most minor and self-limiting
- SSI in 5 (5%) cases with a deep SSI in 1 dog
- Incisional herniation in 4 (4%)
31/154 (20%) laparoscopic OVE complications
- 17 (11%) wound healing complications, most minor
- 5 (3%) superficial SSI and 0 deep

Do prevalence rates and severity of acquired urinary incontinence differ between dogs spayed by laparoscopy or laparotomy?
- # lap OVH -> AUI?
- # open OVH -> AUI
- risk factors?
Among 308 dogs, 30 and 29 dogs spayed by laparotomy and laparoscopy, were affected by AUI
The identified risk factors for AUI were age and time interval since spaying; NOT surgical approach
