🔍 Key Findings

• Lymphaticovenous anastomosis (TD to AV) was successfully performed in all 8 feline cadavers using a microvascular anastomotic coupler (MAC).
• Anastomotic patency was confirmed intraoperatively and postoperatively in 7/8 cats via contrast lymphography or retrograde venography.
• Dissection and anastomosis took a median of 120 minutes, with minimal technical complications.
• A 1.5 mm MAC was used in 6 cats, and a 2.0 mm in 2 cats; TD diameter ranged 1.0–1.5 mm, AV up to 2.25 mm.
• Challenges included vessel twisting and luminal patency issues, resolved intraoperatively with minor adjustments (e.g., repeat pinning, tacking suture).
• MAC use eliminated need for hand-suturing, lowering skill demands but requiring precise alignment.
• Technique provides direct lymphatic-to-venous drainage, potentially reducing the stimulus for collateral vessel formation.
• May serve as a future treatment option for feline idiopathic chylothorax, warranting further in vivo studies.

🔍 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.

🔍 Key Findings

• CBLO was effective for stifle stabilization in skeletally immature dogs with CrCL injuries, avoiding disruption of proximal tibial growth plates.
• Radiographic union of the osteotomy occurred in a mean of 6 weeks (range: 4–8 weeks), indicating rapid bone healing.
• Full limb function was restored in all cases by long-term follow-up (mean 23 months), including dogs with initial complications.
• Two dogs developed 19° valgus deformities due to screw interference with the proximal tibial physis; both were corrected surgically with return to function.
• One dog developed 10° recurvatum due to over-rotation of the tibial plateau, but retained full function without revision.
• CCS (countersink compression screw) caused early apophyseal closure in older dogs but had no adverse clinical effects.
• In contrast, K-wire or plate-only fixation preserved open apophysis, suggesting implant choice may influence growth.
• No meniscal injuries were observed, and all CrCL injuries were managed arthroscopically — 6 complete, 6 partial, 4 avulsions.

🔍 Key Findings

• Overall closure-related complication rate was 14.1%, lower than previously reported (17–78%).
• No clinically meaningful difference in complication rate between orthopedic wire (17.4%) and suture (11.5%) closure methods.
• Dog size (≥20 kg) was the only significant risk factor associated with increased closure-related complications (p = .01).
• Type of closure (wire vs. suture) did not affect risk, even in larger dogs.
• Suture closure showed a non-significant trend toward fewer complications (mean reduction 2.3%, 95% CI: –9.1% to +4.5%).
• Most complications were mild (62%), with only 10 severe cases requiring surgical revision.
• Infection rate was low (2.7%), and not significantly different between wire and suture.
• Suture closure is a valid alternative to wire, including in large dogs, based on this large, multi-institutional study.

🔍 Key Findings

• Patient-specific 3D-printed PCL/β-TCP scaffold enabled successful zygomatic arch reconstruction in a dog.
• Complete surgical resection of a zygomatic parosteal osteosarcoma was achieved, with a 0.3 mm histologically clean margin.
• Post-op imaging showed progressive tissue ingrowth into the scaffold, with Hounsfield Units increasing from 20.4 to 97.8 over 10 months.
• No complications (e.g., infection, displacement) or tumor recurrence were noted at 16-month follow-up.
• Use of a patient-specific osteotomy guide improved anatomical fit and facilitated precise excision and implant placement.
• Facial symmetry and orbital stability were maintained throughout follow-up.
• The scaffold remained structurally stable despite limited bone regeneration, suggesting connective tissue filled the defect.
• Topical mitomycin C was applied intraoperatively for possible anti-neoplastic effect, but efficacy remains unclear.

🔍 Key Findings

• Zurich mini-cementless THA was successful in 9/10 hips in dogs <4 kg, with no lameness at 52 weeks in completed cases.
• Helsinki Chronic Pain Index significantly improved from a mean of 19.8 to 2.3 at 52 weeks (p = 0.0141).
• Fluoroscopy improved implant positioning, especially in LCPD and HD cases, aiding in accurate reaming and alignment.
• Intraoperative complications occurred in 2/10 cases, including acetabular fractures; one case required discontinuation.
• Prophylactic bicortical screws and reinforcement plates were used in cases with rotational instability or cortical compromise and were effective in preventing loosening/fractures.
• Medial patellar luxation improved postoperatively in one dog, though recurrence was noted later without surgical correction.
• No stem or implant loosening or fracture occurred over a mean follow-up of 24.4 months.
• CT is recommended in preoperative planning, particularly in luxoid hip dysplasia cases with uncertain bone stock.

🔍 Key Findings

• NAS-ILN had significantly greater stiffness in both axial compression and 4-point bending compared to LCP constructs.
• Ultimate load to failure was significantly higher for NAS-ILN in compression (804 N vs 328 N) and bending (25.7 Nm vs 16.3 Nm).
• Torsional stiffness and angular deformation were similar, but NAS-ILN resisted higher torque to failure than LCP (22.5 Nm vs 19.1 Nm).
• No slack was observed with the NAS-ILN construct, unlike older nail designs.
• Failure modes differed: LCPs failed via plate bending; NAS-ILNs failed at the implant or bone near screw holes.
• Titanium alloy and curved design of NAS-ILN provides better anatomic fit and more uniform stress distribution.
• A third, perpendicular locking hole in NAS-ILN may enhance torsional stability but was not utilized in this study.
• The curved, angle-stable design of NAS-ILN is a novel advancement in veterinary orthopedics.

🔍 Key Findings

• This study evaluated whether high-fidelity surgical simulator training improved live animal and student outcomes in a feline OHE teaching lab involving 186 cats and 146 students.
• Simulator training significantly improved surgical performance and outcomes:
  • Live surgery was 6 minutes shorter on average in the SIM group vs. NO-SIM (115 ± 21 min vs. 121 ± 16 min, p = .04).
  • Pain scores ≥5/20 occurred in 1% of SIM group cats vs. 15% of NO-SIM group cats (p < .01).
  • Rescue analgesia was needed less frequently in the SIM group (5% vs. 15%, p = .03).
  • Student confidence was significantly higher in the SIM group (median 7/10 vs. 6/10, p < .01).
• The simulator used a realistic abdominal model with friable tissues and required performance of a full OHE procedure.
• The study design was nonrandomized, grouped by class year, with limitations including lack of blinding during pain assessment in year two.
• Authors concluded that pre-lab simulator competency improves both animal welfare and student confidence, recommending it as a prerequisite for live surgical training.
