🔍 Key Findings

• No difference in initial leak pressure (ILP) or maximum intraluminal pressure (MIP) between cooled (17–29 h) and fresh enterotomy constructs.
• Wall thickness of duodenum and jejunum did not differ between fresh and cooled samples.
• Leak locations (suture holes vs clamp sites) were similar between groups; not statistically different.
• Volume of infusion did not influence ILP or MIP outcomes.
• Mean ILP values: Control = 600 mmHg (maxed), Fresh = 200 mmHg, Cooled = 131 mmHg; CE vs FE difference was not significant.
• Intraluminal diameter was largest in the ileum, followed by jejunum and duodenum.
• Cadaveric intestine cooled ≤29h may be reliably used in ex vivo feline leak pressure studies.
• First report of gross small intestinal lengths by region in cats—useful for resection planning.

🔍 Key Findings

• Use of smoke evacuators reduced ultrafine particle concentrations by 56.4% during approach to the proximal tibia for TPLO in dogs.
• Mean intraoperative particle concentrations were significantly higher in surgeries without smoke evacuation (1352 ppc vs. 763 ppc, P < .0001).
• Maximum particle concentrations were six times higher without smoke evacuation (62,450 ppc vs. 10,100 ppc, P < .0001).
• Particle counts increased above baseline regardless of evacuator use, confirming electrosurgery contributes substantially to airborne particles.
• Surgeons noted reduced odor and health concerns when using the smoke evacuator, despite initial visibility limitations due to pencil attachment.
• Standard surgical masks do not protect against ultrafine particles, underscoring the importance of smoke mitigation systems.
• The smoke-evacuation unit did not eliminate all ultrafine particles, suggesting optimization (e.g., higher power setting) may be beneficial.
• This is the first clinical veterinary study to measure surgical smoke reduction using evacuators during TPLO.

🔍 Key Findings

• Postoperative complications occurred in 20% of stifles, including 7.5% minor, 10.3% surgical, and 3.4% medical complications.
• The PROSPECT machine-learning model achieved high predictive accuracy: 92.3% for surgical complications, 91.9% for minor, and 94.3% for medical.
• Top predictive features included surgical technique, implant type, patient age, and surgeon identity.
• Surgeon-specific variables influenced predictions, indicating operator experience and technique matter.
• Engineered interaction features (e.g., breed × implant) were more predictive than raw clinical data alone.
• Rottweiler, intact male status, and higher bodyweight were associated with increased complication risk; Labradors had decreased risk.
• Model calibration was strong, especially for high and low probability predictions; midrange predictions were less reliable.
• The model supports individualized, probabilistic risk assessment, which could inform client counseling and tailored postoperative care.

🔍 Key Findings

• Mediastinoscopy was technically feasible in large-breed canine cadavers using a SILS port and standard laparoscopic instruments.
• The left tracheobronchial lymph node (LTBLN) was successfully retrieved in all cadavers (7/7), while cranial mediastinal lymph nodes were retrieved in only 1/7.
• Postprocedural pleural gas was observed in 4/7 cadavers, likely due to CO₂ insufflation.
• Instrument limitations with a human-designed mediastinoscope led to preference for laparoscopic instruments and SILS port for improved access and visualization.
• Complication rates were low, with only two minor (Grade 1) adverse events (pleural tear and LN rupture).
• Obesity and mediastinal fat were cited as potential challenges to visualization and node retrieval.
• NASA-TLX workload scores were lowest for tracheobronchial nodes, indicating these were the easiest to access.
• The authors concluded this approach may facilitate minimally invasive biopsy or resection of cranial mediastinal masses in live dogs, but clinical trials are needed to validate safety and efficacy.

🔍 Key Findings Summary

• 22 dogs (36 shoulders) with shoulder OCD randomly assigned to COPLA scaffold (n=19) or Control (n=17) group
• At 6 months: Significantly fewer dogs in COPLA group had OA (14% vs. 67%; p = 0.019)
• At 1.5 years: OA prevalence increased in both groups with no significant difference (COPLA: 64%, Control: 60%)
• HCPI (pain index) increased significantly at 1 week post-op in COPLA dogs only (p = 0.001), but later normalized
• Static weight-bearing improved only in unilaterally operated COPLA limbs (p = 0.015)
• One dog in COPLA group had a fragment dislodge requiring arthroscopic removal
• Overall, COPLA scaffold may provide short-term benefit in OA reduction, but long-term outcomes were similar

🔍 Key Findings Summary

• Finite element analysis compared intact radii vs. locking plates placed 1 mm or 3 mm above the bone
• LP placement significantly reduced tensile (maximum principal) stress on cranial cortex, potentially causing implant-induced osteoporosis
• Shell element findings:
  • Max principal stress significantly lower in both LP groups vs. intact (p < 0.05)
• Solid element findings:
  • Equivalent stress higher and max principal stress lower in LP groups
• Implication: Tension reduction may impair bone remodeling; implant design and placement height affect stress environment

🔍 Key Findings

Subject: 7-year-old Labrador underwent cementless total knee replacement (TKR) due to severe stifle OA.

Clinical function:

• Improved ROM from 90° pre-op to 120° post-op.
• Weight-bearing increased from toe-touching to 70% bodyweight by 6 weeks post-op.
• No visible lameness by 14 weeks.

Implant performance:

• No complications at any follow-up points.
• No osteolysis, loosening, or metallosis at 6-year necropsy.

Wear evaluation:

• Mild UHMWPE insert wear, localized to caudal edges.

Histologic findings:

• Robust osseointegration at implant-bone interface.
• Fibrous tissue only in areas lacking porous coating.

Conclusion:

• Cementless TKR demonstrated excellent 6-year survival and functional outcomes.
• Support for considering early surgical intervention in severe stifle OA.

🔍 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.

🔍 Key Findings Summary

• Study Design: Retrospective study of 100 radiographs using in silico and clinical data
• Mean preoperative TPA: 28.6°, higher in small dogs than large (p = .02)
• Mean planned TPA (in silico): 7.6°, not achieving 5° target (p < .01)
• Median postoperative TPA: 5.5° overall; higher in small dogs (7°) vs large (4.5°) (p = .06)
• Postoperative ostectomy position: More distal than recommended; average = 8.6 mm
• Increased distalization → greater under-correction of TPA (p = .01)
• Most accurate correction occurred when ostectomy was ≤7.5 mm from patellar tendon
• Wedge angle categories (TPA-Pre minus 5–2°) were used based on pre-op TPA

🔍 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
