In Clarke 2022 et al., on nasopharyngeal collapse severity, what was the statistical outcome of comparing pre- and postoperative collapse measurements?
🔍 Key Findings
- Nasopharyngeal collapse was significantly more severe in brachycephalic dogs (median 65%) than in nonbrachycephalic controls (median 10%) (p = .0001).
- Postoperative fluoroscopy showed no significant improvement in nasopharyngeal collapse (p = .0505), despite reported clinical improvement.
- 70% of brachycephalic dogs had ≥50% collapse; 26% had 100% collapse preoperatively.
- All owners of surgical cases reported clinical improvement, including reduced respiratory noise and improved exercise tolerance.
- Surgical techniques used included combinations of alaplasty, staphylectomy, sacculectomy, and tonsillectomy.
- Improvement in nasopharyngeal dimensions was variable, with some dogs improving ≥45%, some worsening, and one dog showing a 100% increase post-op.
- Pharyngeal collapse may not be solely anatomical; neuromuscular dysfunction (e.g., reduced pharyngeal dilator muscle function) may contribute.
- Current surgical techniques may not address functional airway abnormalities, suggesting a need for multimodal or targeted interventions.

In Mullen 2024 et al., on NIRF for GDV, which region showed significantly lower fluorescence intensity in nonviable gastric tissue?
🔍 Key Findings
- NIRF altered surgical strategy in 3 of 20 GDV dogs, identifying necrosis not appreciated subjectively.
- Fundic fluorescence <10% indicated histologically confirmed gastric necrosis.
- In 1 dog, NIRF revealed nonviability despite the surgeon’s impression of viability.
- Staple line fluorescence resembled viable tissue in the only stapled gastrectomy, suggesting preservation of perfusion.
- GDV dogs (even “viable”) showed lower fluorescence vs. healthy controls, indicating subclinical vascular compromise.
- Histology confirmed full-thickness necrosis in all 4 dogs with NIRF-defined nonviability.
- Pre-op lactate was significantly higher in nonviable GDV dogs (8.55 vs 4.89 mmol/L, p=0.03).
- No complications were reported from ICG use; imaging was safe and repeatable.

In Wang 2025 et al., on TPLO osteotomy alignment, what was a potential **advantage of using intraoperative fluoroscopy** in challenging cases?
🔍 Key Findings
- Fluoroscopy-guided osteotomy placement achieved a median postoperative TPA of 3° (range: 0–4.5°), showing excellent accuracy.
- The D1 measurement (from patellar ligament insertion to osteotomy exit) was more reproducible and accurate intraoperatively than D2.
- Median R1 value (D1-based) matched the intended 21 mm radius with only 0.5 mm deviation, while R2 deviated by 2.5 mm.
- Real-time fluoroscopy allowed dynamic limb positioning and reduced osteotomy placement variability.
- Intraoperative fluoroscopy reduced reliance on preoperative planning, especially in cases with difficult anatomy or positioning.
- Radiation exposure was minimal (avg. 3 images per case) and within safe limits using standard protection protocols.
- Study standardized to 21 mm blades and excluded dogs with developmental orthopedic conditions to reduce confounders.
- Targeting a lower postoperative TPA (3°) may reduce meniscal load and cranio-caudal instability, though long-term outcomes require further study.

- 3 severe complications: capsulorrhaphy tear, FPS fabellar tear, septic arthritis.
- Long-term results (13/16 cases):
- 85% lameness-free.
- 77% full function; 23% acceptable.
- 0 reluxations reported by owners.

In Downey 2023 et al., on thoracoscopic lobectomy, what was the long-term outcome for dogs that survived to discharge?
🔍 Key Findings
- Thoracoscopic (TL) or thoracoscopic-assisted (TAL) lobectomy was successfully performed in 12 dogs with non-neoplastic pulmonary consolidation (PC).
- 44% (4/9) of TL cases were converted to open thoracotomy due to adhesions or poor visualization—higher than rates for neoplastic lobectomies.
- OLV was successful in 7/9 TL dogs; unsuccessful attempts were managed with intermittent ventilation, mostly in brachycephalic breeds.
- Median hospital stay was 3 days; 91.7% (11/12) survived to discharge, and 100% of survivors showed no recurrence at median 24-month follow-up.
- Complications were mostly minor: pneumothorax (2), minor hemorrhage (3), dehiscence (1), and 1 fatality due to BOAS complications.
- Histopathology showed infectious pneumonia in 10 dogs, and in 4 cases, foreign body migration was suspected as the underlying cause.
- Median surgical time for TL was 90 minutes; conversion correlated with longer symptom duration (median 90 vs. 7 days).
- Postoperative recovery was excellent in all surviving dogs, with one case of persistent cough attributed to concurrent heart disease.

In McCarthy 2022 et al., on 3D drill guide accuracy, how did CT and 3D analysis compare in assessing drill angles?
🔍 Key Findings
- 3D-printed drill guides (3D-GDT) significantly reduced craniocaudal and dorsoventral drilling angle deviation compared to free-hand drilling technique (FHDT), with statistical significance (p < .0001 and p = .01 respectively).
- No sacral corridor breaches occurred with 3D-GDT, whereas FHDT resulted in 20% drill exit incidences (3/15 cases).
- 3D-GDT had lower deviation from optimal drill trajectory at end points in all axes: craniocaudal (1.84 ± 1.6 mm vs. 4.18 ± 2.4 mm), dorsoventral (1.11 ± 1.0 mm vs. 2.4 ± 1.5 mm), and 3D linear (2.47 ± 1.4 mm vs. 5.35 ± 2.2 mm), all statistically significant.
- Strong correlation (r = 0.77) between CT and 3D software measurements validated method reliability.
- 3D guide trajectories showed consistent proximity to the optimal trajectory, especially at drill endpoints, indicating reduced variability in execution.
- 3D-GDT was developed using open-source software and inexpensive materials, supporting future clinical application.
- Major errors in FHDT occurred primarily at the drill endpoint, underscoring the challenge of maintaining optimal angulation during free-hand drilling.
- The sacral corridor was recharacterized as pyramidal (not quadrilateral), with implications for safer implant placement.

In Glenn 2024 et al., on overall diagnostic performance, which algorithm had the highest accuracy?
🔍 Key Findings Summary
- Population: 754 soft tissue or orthopedic procedures in dogs and cats
- SSI Rate: 62/754 (8.2%)
- Algorithms Evaluated:
- Algorithm 1: Highest sensitivity (87.1%) → best for "rule-out"
- Algorithm 2: Highest specificity (97.9%) → best for "rule-in"
- Algorithm 3: Highest overall accuracy (95.5%)
- Active vs. Passive Surveillance:
- Active surveillance detected 12 additional SSIs (19.4%) missed by passive
- Active surveillance increased detection rate by 24%
- Timing: Most SSIs occurred within 30 days; late infections (after 90 days) were rare and implant-related
- Conclusion: Client questionnaires are a valid and scalable tool for SSI detection; active surveillance improves outcomes

In Antonakakis 2022 et al., on telovelar tumor resection, what histologic feature supported a diagnosis of choroid plexus carcinoma?
🔍 Key Findings
- Telovelar approach enabled complete resection of a fourth ventricle choroid plexus tumor in a dog without postoperative complications.
- Postoperative MRI confirmed gross total tumor removal, and the dog remained neurologically normal 28 months post-surgery.
- The tela choroidea was used as a surgical landmark and incised to allow atraumatic access to the tumor.
- Cerebellum was spared using this technique, minimizing risk of cerebellar injury (e.g., cerebellar mutism).
- No hemorrhagic complications were noted during surgery due to dissection through avascular planes.
- Histopathology favored choroid plexus carcinoma based on mitotic index (9/10 HPFs), though definitive diagnosis remained pending.
- The case highlights the utility of telovelar over transvermian approach, given its minimally traumatic nature and improved exposure.
- Survival beyond 2 years without adjunctive therapy suggests surgical excision alone may be curative in select cases.
