🔍 Key Findings

• 78% of cats that developed postattenuation neurologic signs (PANS) after congenital portosystemic shunt (cPSS) surgery survived to 30 days.
• Postattenuation seizures (PAS) were associated with significantly decreased 30-day survival (50% vs. 78%; OR: 0.015, p = .005).
• Treatment of PANS with propofol was a negative prognostic factor (OR: 0.112, p = .0008).
• Generalized PAS accounted for most seizure cases and were more frequently fatal than focal or unknown-type seizures.
• Pretreatment with levetiracetam (LEV1 protocol) showed a trend toward improved survival (100% vs. 60.6% in untreated cats), though not statistically significant (p = .06).
• Shunt morphology, method of attenuation, and study period (early vs. late) were not significantly associated with 30-day survival.
• Electrolyte, glucose, and ammonia abnormalities were not strongly linked to survival outcomes in this study.
• Majority of PAS-related deaths were due to uncontrolled generalized seizures or euthanasia because of severity.

🔍 Key Findings

Population: 24 dogs (<8.5 months) undergoing unilateral cementless THR.
Growth Impact:

• Operated femurs showed ~11.5% less trochanteric growth than controls (p = .002).
• No significant difference in femoral diaphyseal + epiphyseal length (p = .712) or femur overall (p = .465).

Cortical Width:

• Increased significantly at 10 mm distal to trochanter (4.6% increase, p = .037) and at 50% femoral length (8.5% increase, p = .030).

Clinical relevance: Despite measurable changes, no clinically significant impairment to femoral length occurred.
Effect Sizes:

• Moderate negative for trochanteric growth.
• Moderate positive for proximal femoral width.

🔍 Key Findings

• Roux-en-Y procedures were successfully completed in all 11 cases (6 dogs, 5 cats), despite case complexity and disease severity.
• Median survival post-discharge was longer in cats (365 days) vs. dogs (82 days), with better outcomes in non-neoplastic vs. neoplastic disease (192 vs. 5 days).
• Complication rate was high, with septic peritonitis, dehiscence, and cardiac arrest as leading causes of postoperative death; mortality rate = 36%.
• Dehiscence rate was 8.6% (2 of 23 anastomoses), considered lower than typical rates for GI anastomoses in high-risk patients.
• Feeding tubes (gastrostomy/jejunostomy) were used in all cases, enabling early nutritional support and stomach decompression.
• Postoperative nausea and vomiting were common but mostly self-limiting; managed with metoclopramide, cisapride, and antiemetics.
• Choledochojejunostomy was preferred when common bile duct was dilated, offering a favorable size match and potentially reducing bile leakage.
• Roux-en-Y reduced typical Billroth II complications (e.g., bile reflux, afferent loop syndrome, dumping syndrome), with none observed in discharged patients.

🔍 Key Findings Summary

• 3 dogs developed permanent fibular nerve dysfunction following TPLO
• Common findings:
  • Drill hole or screw in caudal tibial cortex just distal to osteotomy
  • Caudal malpositioning of TPLO plate (esp. right limb of case 3)
  • Post-op signs: cranial tibial atrophy, knuckling, exaggerated gait, no hock flexion
• One case had confirmed deep/superficial fibular neuropathy via electrodiagnostics
• Recommended prevention: avoid overly caudal drill paths; careful gait assessment at follow-up is key

🔍 Key Findings

• Cholelithiasis was the most common indication for cholecystectomy in cats.
• Perioperative complications were frequent, with intraoperative hypotension in all recorded cases and postoperative anemia in 14 cats.
• Perioperative mortality was 21.7%, lower than historical rates for feline biliary surgery.
• 78.3% of cats survived to discharge, and 83.3% of those lived >6 months; 44.4% survived >3 years.
• Vomiting was the most common short- and long-term complication, though most cats were medically managed.
• Concurrent EHBDO was not a contraindication provided CBD patency was restored.
• Positive bacterial cultures were found in 15 cats, with E. coli and Enterococcus faecalis most common.
• Owner-reported outcomes were excellent in all cats that survived long-term.

🔍 Key Findings

• Survival rates did not differ between immediate (90 min) and delayed (≥5 h) surgical stabilization groups at discharge or 1-month post-op (approx. 80% survival in both).
• Hyperlactatemia at 24 hours post-fluid therapy was significantly associated with in-hospital and 1-month mortality (P = .01 and P = .02).
• Persistent tachycardia during hospitalization was linked to increased 1-month mortality (P = .015).
• Partial gastrectomy was required in ~6–10% of cases, with high associated mortality.
• Preoperative stabilization protocols (trocarization, nasogastric tube) allowed safe surgical delays up to 13.7 hours without impacting survival.
• Degree of gastric torsion differed between groups; more 0° torsions in delayed cases, potentially due to decompression-induced derotation.
• No difference in post-op complications such as arrhythmias, hypotension, or AKI between groups.
• More intra-anesthetic deaths occurred in immediate surgery group, highlighting importance of adequate pre-op stabilization.

🔍 Key Findings

• Postoperative Protein C (PC) activity increased in 78.7% of dogs, and was significantly higher in dogs with excellent clinical outcomes.
• Complete acute shunt occlusion resulted in higher postoperative PC activity (96.3%) and better ultimate clinical outcomes than incomplete occlusion.
• Preoperative PC was not predictive of clinical status, but postoperative PC was associated with improved outcomes.
• Standard biochemical markers (HCT, MCV, ALB, BUN) also improved postoperatively, especially in dogs with excellent clinical outcomes.
• Dogs requiring a second procedure had significantly lower postoperative PC (43.5%) than those not requiring further intervention (78.5%).
• Repeat procedures improved PC and BUN values, with PC increasing significantly after second intervention (to 69.8%).
• PC normalization (within reference interval) occurred in 87.5% of dogs with excellent clinical status, compared to only 12.5% in those with poor status.
• Clinical outcome classification (excellent/fair/poor) correlated with biochemical normalization and lack of need for diet/medications.

🔍 Key Findings

Case 1: Chest wall lift improved oxygenation (PaO₂ increased from 179.4 to 306.3 mmHg) and enabled thoracoscopic-assisted lobectomy in a cat with pleural effusion and pulmonary carcinoma.
Case 2: Chest wall lift using a Steinmann pin allowed 3-port thoracoscopic lobectomy for a bronchial foreign body; no complications observed.
Both cats: Lift increased working space and eliminated need for thoracotomy; no device-related complications.
Pretied ligating loops (PLL) were effective for hilar vessel ligation—preferred over staplers or self-locking ligatures in feline thorax.
Conclusion: Thoracic lift is a novel, minimally invasive method enhancing thoracoscopic procedures in small patients, particularly cats.

🔍 Key Findings

• Arthroscopically assisted stabilization with an IAD was feasible in cadaveric canine shoulders using both bone anchor and suture-toggle techniques.
• Suture-toggle repair was successfully performed in all specimens, while bone anchors could not be deployed in 3/10 shoulders, indicating lower feasibility.
• Median surgical time was shorter for the suture-toggle group (25.5 min) compared to the anchor group (37.3 min).
• Postoperative abduction angles returned to baseline in the anchor group, while the suture-toggle group had slightly reduced angles, suggesting possible overtightening.
• Violation of the articular surface occurred in 2 anchor specimens and 1 suture-toggle specimen, but none were considered likely to be clinically significant.
• Overall targeting accuracy using the IAD was 88%, supporting its utility in guiding tunnel/anchor placement.
• CT measurements showed acceptable bone stock and insertion angles, but anchor insertion angles were lower than optimal for mechanical pullout strength.
• Suture-toggle technique was considered simpler and more consistent, with fewer complications and faster execution than anchor placement.
