In Hertel 2025 et al., on portal venotomy for insulinoma, what material and technique were used to close the venotomy site?
🔍 Key Findings
- Portal venotomy enabled successful en bloc resection of a pancreatic insulinoma and associated thrombus in the portal vein, a novel approach in veterinary literature.
- Temporary portal vein occlusion (15 min) was well tolerated, causing only transient small intestinal congestion without lasting hemodynamic compromise.
- No intraoperative hemorrhage occurred following vascular isolation and venotomy repair with 5–0 polypropylene in a simple continuous pattern.
- Postoperative complications were minimal, with only moderate pancreatitis managed medically and no portal hypertension observed on follow-up imaging.
- Histopathology confirmed insulinoma, with no initial metastasis; CT at 6 months revealed hepatic and peritoneal metastases but no local recurrence at the venotomy site.
- Portal vein luminal stenosis occurred post-repair but was clinically insignificant.
- Advanced CT imaging and 3D printed modeling significantly enhanced surgical planning and anatomical assessment.
- Surgical excision achieved good short-term outcomes, and the dog was alive and euglycemic one year later despite metastatic disease.

In Marshall 2022 et al., on fracture healing in dogs, how did **radius and ulna fractures in toy breeds** perform regarding delayed or non-union?
🔍 Key Findings
- Delayed union occurred in 13.9% of fractures; non-union in 4.6%; mal-union in 0.7%
- Major implant failure increased odds of delayed or non-union by 12.9×
- Surgical site infection increased risk 3.2×; bone grafting (any type) was also associated (OR 3.3)
- Comminuted fractures had 4.2× greater odds of delayed or non-union
- Older age increased risk, with odds increasing by 21% per year
- Radius and ulna fractures in toy breeds were not high risk, contrary to historical belief
- Most non-unions required revision surgery with rhBMP-2 or autograft to achieve union
- Ilium fractures showed 0% delayed/non-union — possibly due to robust muscle envelope

In Bilmont 2025 et al., on cup version comparison, what best describes the relationship between pelvic extension and open face version?
🔍 Key Findings
- Open face version was significantly greater than truncated face version by 14°–22° (p <.001).
- Open face version increased linearly with inclination and pelvic extension, while truncated face version remained largely stable.
- Truncated face version is an unreliable surrogate for open face version.
- Accurate interpretation of cup version should include both truncated face version and inclination.
- Canine 3D pelvic model and CT-based simulation used for all measurements.

In Lemmon 2025 et al., on synovitis severity scoring, what was concluded about the impact of bucket handle meniscal tears on synovitis severity?
🔍 Key Findings
Synovitis was present in 100% of canine stifles with CCL disease (n = 163).
The most frequent severity score was 3/5 (55.2%), followed by 4/5 (24.5%).
Higher synovitis scores were significantly associated with:
- Higher median cartilage scores (p = .042, OR = 2.1 per unit increase)
- Longer duration of clinical signs (p < .001, OR = 1.27 per month)
Bodyweight (p = .083) and sex (p = .17) were not statistically significant in multivariable analysis.
Bucket handle meniscal tears were not associated with synovitis severity.
Clinical implication: Earlier intervention may help reduce synovitis and slow OA progression.

🔍 Key Findings
- Overall survival to discharge: 107 of 132 dogs (81%)
- Quartile improvement: Survival increased steadily from 67% in Q1 to 91% in Q4
- Q1: 22/33 survived
- Q2: 27/33
- Q3: 28/33
- Q4: 30/33
- Statistical significance: Higher operative rank significantly associated with improved survival (p < .05)
- Median cross clamp time (XCT): 73 min (range 40–165), but increased again in Q4
- Fatalities (n=25) were often due to:
- Failure to wean from CPB
- Intracranial vascular events (stroke)
- Intrathoracic hemorrhage
- Breed representation: CKCS (23.5%), Chihuahua (22%), Crossbreeds (21%)
- Stages of MMVD: Stage C (67%), Stage D (27%), Stage B2 (6%)
- Emphasis on deliberate multidisciplinary teamwork for outcome improvement
- Highlights importance of technical and non-technical team skills, procedural standardization, and consistent personnel

In Cherzan 2023 et al., on subcutaneous mast cell tumors, what proportion of dogs with lymph node metastases developed tumor recurrence?
🔍 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 Wylie 2025 et al., on femoral implant accuracy, what is true regarding the simplified pivot shift grading system introduced in the study?
🔍 Key Findings
- Accurate femoral isometric placement was achieved in 63% of cases, significantly more with SwiveLock (78.6%) than FASTak (38.9%).
- Inaccurate placement was associated with increased internal tibial rotation at follow-up (p = .009), suggesting potential implant failure.
- Pivot shift grade improved in 90.9% of stifles postoperatively, regardless of implant positioning accuracy.
- SwiveLock implants had a faster learning curve and higher placement accuracy than FASTak.
- Higher patient weight was linked to more accurate implant placement (p = .012), likely due to easier anatomical landmark identification.
- No correlation found between implant type or positioning accuracy and final pivot shift grade at 6 weeks.
- Minor and major complications were low and not significantly different between implant types.
- A simplified 2-grade pivot shift system was proposed for clinical use (Grade 1: glide, Grade 2: clunk), aiding intraoperative decision-making.

In Brisimi 2022 et al., on tracheal anastomosis tension, which statement is true?
🔍 Key Findings
- Tracheal anastomoses in immature dogs failed at significantly lower distraction forces (44.91 ± 59.03 N) than in adults (149.31 ± 45.36 N; _P_ = .007).
- Immature tracheae tolerated significantly more elongation before failure (39.75 ± 5.45%) than adult tracheae (30.57 ± 7.19%; _P_ = .0012).
- All constructs failed by suture tearing through the annular ligament, primarily near the dorsal tracheal ring.
- Overlapping of tracheal ends was seen in 50% of specimens across both age groups, suggesting limitations in tissue apposition with the chosen technique.
- Simple continuous pattern using 2-0 polypropylene was used; this pattern provides superior tensile strength compared to simple interrupted, but apposition may be suboptimal.
- Tracheal elasticity in immature dogs may allow longer resections, but the lower tensile strength necessitates reinforcement.
- Annular ligament-cartilage technique with 4-mm suture spacing showed variable results; smaller bites and nylon suture may improve outcomes.
- Ex vivo setup using frozen-thawed tracheae is a limitation, but prior studies support comparability with fresh tissue.

In Schuenemann 2025 et al., on biceps tenodesis, what LOAD score pattern was observed in the cohort?
🔍 Key Findings
- Case series of 6 shoulders in 5 working/sporting dogs. Conditions treated: 3 partial biceps ruptures, 3 luxations with fraying.
- All treated with biceps tenodesis using a bioabsorbable anchor (Weldix 2.3 mm).
- All dogs returned to function (some to high-level sports); lameness resolved within 1–5 weeks.
- No implant-related complications with anchor-only cases. One dog had seroma and later infection but recovered.
- Tendon clamp (used in 2 cases) caused irritation in one dog → resolved after removal.
- CT follow-up confirmed integrity; drill holes filled with bone.
- Median LOAD score: 12; higher in older dogs or with concurrent conditions.
- Authors suggest tenodesis offers more stability and faster return to function than tenotomy in working dogs.
- Larger, controlled studies are recommended.
