In Wilson 2025 et al., on acetabular measurement accuracy, what factor significantly reduced measurement accuracy across all methods?
🔍 Key Findings
Study population: 73 hips from 60 dogs undergoing cementless THR.
Methods evaluated:
- ACVD/ACOLL (acetabular circle on VD or OLL view)
- ALVD/ALOLL (acetabular line)
- FHCVD/FHCOLL/FHCCCHB (femoral head circle)
- Intraobserver repeatability and interobserver consistency were excellent for ACVD and ACOLL.
- FHC methods consistently underestimated actual cup size by 2.4–3.6 mm.
- AC and AL methods had low bias (±0.5 mm) and better predictive value.
- OA severity negatively affected the accuracy of all measurements (p < .05).
- Highest predictive accuracy was ~49% using ACVD with rounding down protocol.

In Cherzan 2023 et al., on subcutaneous mast cell tumors, which characteristic was **not** significantly associated with recurrence, DFI, or survival in dogs with subcutaneous mast cell tumors?
🔍 Key Findings
- Local recurrence occurred in 17.8% of dogs, and was associated with significantly decreased survival (551 vs 1722 days, p = .0038).
- Lymph node metastasis occurred in 26.7% of dogs and was significantly associated with shorter disease-free interval (194 vs not reached, p = .0012) and lower survival (551 vs 1722 days, p = .043).
- Mitotic index >7 was significantly associated with higher recurrence (80% vs 22.5%, p = .02), shorter DFI (139 vs not reached days, p < .001), and shorter survival (247 vs 1722 days, p = .05).
- Infiltrative growth pattern was associated with shorter DFI (268 vs 1864 days, p = .011), but not with survival or recurrence.
- Incomplete margins (≤1 mm) were not significantly associated with recurrence (p = .085), but did correlate with shorter DFI (p = .043).
- Chemotherapy or radiation therapy was associated with shorter DFI and survival, likely due to selection bias for more aggressive disease.
- Tumor size >3 cm was associated with decreased survival (p = .031), but not with recurrence or DFI.
- Multinucleation and necrosis were not associated with prognosis outcomes.

In Loh 2024 et al., on treatment outcomes for CvHL in dogs, which surgical technique had an 88.2% success rate?
🔍 Key Findings
- Low-trauma events caused 82.9% of CvHL cases; Poodles and poodle-crosses represented 49.4% of cases.
- Success rate of hobbles (61.8%) was significantly higher than closed reduction alone (10.3%) or Ehmer sling (18.5%).
- Multivariate analysis found hobbles 7.62x more likely to succeed vs. closed reduction (p = .001).
- Specialist surgeons had higher success with nonsurgical management (OR: 2.68; p = .047).
- Older age associated with better outcomes (OR: 1.15 per year; p < .0005).
- Ehmer sling is not recommended due to high failure and complication rates (60.6%).
- Toggle rod stabilization had a high surgical success rate (88.2%) with low complication.
- No link was found between CvHL and hip dysplasia or OA in most cases (only 2/108 showed OA).

In Foster 2026 et al., on right hepatic lobectomy, what was the most common intraoperative complication observed?
🔍 Key Findings
- Perioperative mortality rate was low (2.9%), with no intraoperative deaths reported.
- Intraoperative complications occurred in 54.3% of dogs, most commonly hemorrhage and cardiovascular events.
- 21% of dogs required blood transfusions, though transfusion was not associated with higher complication risk.
- Advanced hemodynamic support (fluid + cardiovascular) was significantly associated with short-term complications (OR 17.3, p = .029) and shorter survival.
- No surgical method (e.g., TA stapler, vessel sealing device, hilar resection) was associated with increased risk of complications.
- Hepatocellular carcinoma (HCC) was the most common diagnosis (53%), with an MST of 741 days and 17.6% recurrence.
- Surgical margins (complete vs incomplete) were not associated with overall survival time in dogs with HCC.
- The use of preoperative CT and improved surgical instrumentation may have contributed to the lower observed mortality.

In Ellis 2024 et al., what conclusion was drawn regarding sclerosis seen on elbow CT in Guide Dogs?
🔍 Key Findings Summary
- 86 elbows assessed: 32 Guide Dogs, 11 Border Collies
- Guide Dogs showed significantly higher HU values in:
- MCP: min (p = 0.022), mean (p < 0.01), max (p < 0.01)
- Humeral trochlea: mean (p < 0.01), max (p < 0.01)
- Results imply breed-associated HU variation, not necessarily pathologic sclerosis
- Relevance: Important to avoid false positives for elbow dysplasia during CT-based breeding screens
- Good interobserver agreement for mean HU values (ICC ~0.82–0.90)

In Sunlight 2022 et al., on Protein C monitoring, what percentage of dogs required a second intervention following PTCE for IHPSS?
🔍 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.

In Welker 2024 et al., on thoracic duct anastomosis with MAC device, what percentage of dogs had patent anastomoses at 30 days?
🔍 Key Findings
- Anastomosis of the thoracic duct (TD) to the intercostal vein (ICV) using a microvascular anastomotic coupler (MAC) was feasible in all 6 healthy dogs
- Immediate postoperative patency was confirmed in all dogs, but only 4/6 had patent anastomoses at 30 days, with 2 failing due to ICV kinking
- Kinking of the ICV near the azygos vein insertion was the primary failure mechanism, likely from MAC malalignment
- No intraoperative or major postoperative complications occurred, though 2 dogs developed mild seromas
- Use of the MAC device simplified microsurgical anastomosis versus hand suturing, especially in the deep thoracic cavity
- Contrast lymphangiography showed faster clearance from the cisterna chyli postoperatively, suggesting effective flow redirection
- Persistent branches of the thoracic duct may impact outcomes, and should be ligated during surgery
- This technique may be a potential novel treatment for idiopathic chylothorax, improving outcomes by reducing collateral flow stimuli

In Levine 2025 et al., on thoracoscopic pericardiectomy, which approach produced the largest pericardial resection?
🔍 Key Findings
Study design: Randomized cadaveric comparison (n=20 dogs; ILR vs PDR)
Approaches:
- ILR = Intercostal in Left Lateral Recumbency (no OLV required)
- PDR = Paraxiphoid in Dorsal Recumbency (traditional)
Outcomes:
- Pericardiectomy time was shorter for ILR (p = .045)
- Pericardial fragment size was significantly larger in PDR group (p = .004; 23.21 cm² difference)
- Visibility and cardiac exposure were superior in PDR group
Feasibility:
- ILR approach was consistently successful in achieving partial pericardiectomy
- Bilateral ventilation was adequate; no need for OLV
Clinical relevance:
- ILR may improve efficiency when paired with TDL
- PDR remains preferable for cases requiring maximal pericardial resection

In Longo 2022 et al., on CT-guided osteotomies, what percentage of dogs had physiological patellar tracking restored following surgery?
🔍 Key Findings
- 3D CT volume rendering and CAL measurement successfully guided correction of femoral and tibial torsion in dogs with patellar luxation (PL).
- Physiological patellar tracking was restored in 100% (22/22) of cases after detorsional osteotomy.
- 94% of dogs (17/18) had either full or acceptable functional outcomes post-surgery.
- CAL-based correction was accurate in 19/22 cases, confirming reliability of the measurement technique.
- Complication rate was 45%, with major complications in 2/22 cases—both involved combined femoral and tibial osteotomies.
- Combined femoral and tibial osteotomies in the same limb were linked to a higher risk of complications and poorer outcomes.
- Diaphyseal osteotomies offered more implant space, but metaphyseal locations were associated with faster bone healing.
- Use of a TPLO jig or goniometer was not essential—CAL-based bone marking was sufficient in most cases.
