🔍 Key Findings

Design: Ex vivo cadaver study (n=8 dogs, 24 sites)
Comparison: Freehand vs. 3D-printed drill guide-assisted ventral slot (GAVS vs FHVS)
Findings:

• GAVS produced slots not significantly different from planned dimensions (p = .722–.875)
• FHVS produced significantly shorter slots than intended (p < .01)
• No difference in surgical time (p = .071)
• Shape ratio and slot divergence from midline were similar between groups (p > .4)
• Use of guide significantly reduced variability in slot position (63% → 29%), shape (65% → 24%), and divergence (54% → 50%)

Conclusion: 3D-printed guides improved accuracy and consistency of ventral slot creation by novice surgeons; supports future evaluation in live dogs and small breeds

🔍 Key Findings

• The addition of adrenaline (0.00198%) to bilateral maxillary nerve blocks significantly reduced intraoperative hemorrhage in dogs undergoing sharp staphylectomy (median reduction: 77.1%).
• Normalized hemorrhage (g/kg) and total hemorrhage (g) were significantly lower in the adrenaline group (p = .021 and p = .013, respectively).
• Surgeon-assessed hemorrhage scores were also significantly lower in the adrenaline group (median 2 vs. 3; p = .029), indicating improved surgical visibility.
• No adverse effects (e.g. tachycardia, arrhythmia, or hypertension) were observed with adrenaline administration.
• A standardized intraoral approach to the maxillary nerve block was used with 0.5 mL per side regardless of dog size.
• Breed effect observed: English Bulldogs had higher normalized hemorrhage, possibly due to anatomical variation or underdosing relative to size.
• Adrenaline may also prolong local anesthetic action and reduce blood aspiration risks, though this was not directly measured.
• The study supports the routine inclusion of adrenaline in maxillary nerve blocks for staphylectomy in BOAS patients to improve surgical field and reduce bleeding.

🔍 Key Findings

• Portal pressure increased proportionally with insufflation pressure: 38% at 6 mmHg, 95% at 10 mmHg, and 175% at 14 mmHg.
• Exponential model: average increase of 7.45% per mmHg of insufflation pressure (CI: 4.7–10.2%).
• No systemic hemodynamic adverse effects were observed; MAP remained >60 mmHg throughout.
• Portal hypertension threshold (15 mmHg) predicted at ~6.4 mmHg insufflation pressure.
• No statistical impact from patient weight, pressure-to-weight ratio, or order of insufflation rounds.
• Measurement technique was feasible and safe, with only minor challenges (e.g., catheter kinking).
• The study supports use of the lowest insufflation pressure needed for visualization to avoid portal hypertension.
• Baseline portal pressures returned after desufflation, supporting comparison pre- and post-attenuation.

🔍 Key Findings

• Barbed sutures showed comparable leakage pressure to traditional sutures and stapling devices (p = .36).
• No bronchial leaks occurred at physiological pressure (<20 cmH₂O) in any group.
• Leakage at supraphysiologic pressure (20–80 cmH₂O) occurred in 90% of stapler, 80% of traditional, and 60% of barbed suture closures.
• Barbed sutures reduced ligation time significantly compared to traditional sutures (10.7 vs. 14.1 minutes, p < .01).
• Staplers remained fastest, with mean ligation time of 2.4 minutes.
• No knot failure or suture breakage was observed in barbed or traditional suture groups.
• Leakage in barbed sutures occurred mostly at the loop effector zone, but remained within acceptable limits.
• Barbed sutures may offer an effective alternative when staplers are unavailable, impractical, or cost-prohibitive.

🔍 Key Findings

• Traumatic pulmonary pseudocysts (TPP) were diagnosed in 11 patients (9 dogs, 2 cats) using CT after blunt trauma.
• TPPs were identified on radiographs in 64% of cases that were CT-confirmed, highlighting the superior sensitivity of CT.
• Most cases (7/10) were managed conservatively, with complete recovery and no TPP-related mortality.
• Thoracic surgery (lung lobectomy) was performed in 3 dogs, due to persistent pneumothorax or large TPP with perceived risk of complications.
• All pneumothorax cases were managed with thoracostomy tubes, and chest drains were used in 73% of cases.
• Pneumothorax was present in 100% of patients, often bilateral, and pulmonary contusions were reported in 73%.
• One cat was euthanized due to unrelated maxillofacial trauma; no deaths were attributed to TPP itself.
• Long-term follow-up (median 768 days) revealed only 1 case with possible TPP-related pneumonia; others had no complications.

🔍 Key Findings

• Direct suction salvaged more red blood cell mass (rbcM) than swab washing: 88.43% vs 84.74% (p = .015)
• Swab washing still achieved high recovery (84.74%), making it a viable adjunct when suction is not possible
• No significant difference in post-salvage PCV between methods (~34% for Su and ~33.9% for Sw)
• Total salvaged blood volume was significantly higher using direct suction (143 mL vs 139.8 mL; p < .001)
• Leukocytes are removed during salvage, potentially lowering risk of cytokine-mediated transfusion reactions
• Expired pRBCs were used, but device still achieved high RBC recovery, supporting clinical utility
• Swab washing via manual agitation may cause more RBC destruction than direct suction
• Cell salvage may avoid complications of allogeneic transfusions, like storage lesions and immunologic reactions

🔍 Key Findings

• Spinal stabilization with 3D-printed patient-specific drill guides (3D-PSGs) was safe, with no immediate perioperative complications reported.
• 84% of pedicle screws were optimally placed, and only 0.5% breached the spinal canal, reflecting high placement accuracy.
• 80% of dogs experienced no neurologic deterioration postoperatively, indicating reliable short-term safety.
• 3D-PSGs were accurate and reproducible, even across multiple institutions and surgeons.
• Mid-term outcomes were favorable: all dogs were ambulatory, and 90% had static or improved neurologic signs.
• 7 of 10 mid-term follow-ups showed abnormal gait, though owners rated lifestyle ≥3/5, suggesting acceptable function.
• 3D-printed guides enabled precise pedicle screw placement in deformed vertebrae, expanding options in small breeds.
• One dog suffered a T4 spinous process fracture due to overextension of PMMA cement, emphasizing the need for cement placement caution.

🔍 Key Findings

• MEFF occurred in 11.4% (10/88 elbows) following medial-to-lateral transcondylar screw placement in dogs with HIF.
• Screw size to condylar height ratio >41% significantly increased MEFF risk (P = .004, OR 1.52).
• MEFF was not recognized intraoperatively in 60% of cases and was only seen on follow-up or retrospective imaging review.
• Screw loosening was the most common complication (11.2%), observed both with and without MEFF.
• MEFF tended to increase the risk of screw loosening (P = .06), but was not statistically significant.
• Most MEFFs did not require treatment and healed radiographically by 14–17 weeks in monitored cases.
• Shaft screws were used in all MEFF cases, but shaft vs cortical design was not significantly associated with MEFF.
• The clinical impact of MEFF was minor in most cases, although long-term significance is unknown.

🔍 Key Findings

• Neonatal survival to discharge was 93.1% overall, with no significant difference between brachycephalic (94.8%) and nonbrachycephalic (91.8%) breeds.
• Elective C-section significantly improved neonatal survival (99.2%) compared to emergency C-section (87.1%) (p < .001).
• Larger C-section litter size was positively associated with survival (p = .004; OR 1.57), whereas total litter size had no effect.
• Maternal heart rate and stage of labor were associated with neonatal mortality in univariable analysis, but not multivariable.
• Brachycephalism alone was not a risk factor for neonatal mortality (p = .221) in multivariable analysis.
• Emergency C-section was the strongest predictor of neonatal mortality (OR 4.75), regardless of breed.
• Multidisciplinary team approach likely contributed to high survival rates, emphasizing importance of coordinated care.
• Historical factors such as primiparity and maternal age were not associated with mortality in this cohort.

🔍 Key Findings

• Surgeons with smaller glove sizes experienced more difficulty using laparoscopic instruments, especially endoscopic staplers, cup biopsy forceps, and vessel sealing devices.
• Endoscopic stapler was rated the most difficult instrument, with a median difficulty score of 4/10 and 25% usage difficulty.
• Female surgeons reported significantly more difficulty with several instruments due to smaller glove size.
• Reusable instruments were preferred over disposable ones for all tasks.
• Pistol grips were preferred for grasping/retracting and fine dissection, while axial grips were preferred for suturing/knot tying.
• Articulating handles were consistently associated with increased reported difficulty, especially with scissors and cup biopsy forceps.
• Left-handed surgeons had more difficulty operating endoscopic staplers, suggesting limited design inclusivity.
• Surgeons in academic settings reported more difficulty with laparoscopic maneuvers than those in private practice.
