🔍 Key Findings

• 83% of dogs survived to discharge after adrenalectomy for pheochromocytoma.
• Median survival time post-discharge was 1169 days (3.2 years).
• Preoperative alpha-blocker therapy (e.g., phenoxybenzamine) was not associated with improved survival.
• Dogs receiving alpha-blockers had higher intraoperative systolic BP, with median values 170 mmHg vs. 142 mmHg in non-treated dogs (P = .01).
• Intraoperative arrhythmias occurred in 30% of cases, with no difference between dogs receiving alpha-blockers and those not.
• Histologic vascular invasion occurred in ~70% of tumors.
• Tumor recurrence was suspected in 3 dogs, and metastasis in 8 dogs, though not histologically confirmed in most cases.
• Postoperative complications included refractory hypotension, acute kidney injury, and hypertension persisting >48 hours in 10 dogs.

🔍 Key Findings

• Peripheral nerve block (PNB) was preferred by 79% of anesthesiologists; lumbosacral epidural (LE) by 21%; PI <1%.
• Time since board-certification significantly influenced preference: PNB favored by newer diplomates, LE favored by more senior ones (p < .001).
• Employment sector mattered: PNB was preferred more in private practice, LE more in academia (p = .003).
• PNB perceived as more effective, with 78% reporting 81–100% effectiveness; compared to 55% for LE.
• PNB associated with fewer adverse effects (75%) than LE (4%) and PI (21%).
• PNB required less rescue analgesia intraoperatively (57%) and postoperatively (54%) than LE or PI.
• LE preferred for bilateral TPLOs and in smaller dogs; PNB for larger dogs, due to motor function preservation.
• Dexmedetomidine was the most common additive to PNB; bupivacaine-only was most used for PNB.

🔍 Key Findings

• 39 of 40 checklist items for simulated OVH surgical assessment had good content validity (CVI = 0.81)
• Only 1 of 6 items from the OSATS GRS (respect for tissue) met inclusion criteria (CVI = 0.80)
• Checklist showed strong reliability (G-coefficient = 0.85) for moderate-stakes exams
• Modified OSATS GRS showed acceptable reliability (G-coefficient = 0.79)
• Two raters needed for acceptable reliability in high-stakes exams when using the checklist
• Minimal interrater bias found; variance largely due to interaction among student, rater, and item
• Digital recordings were a reliable method of evaluating surgical performance
• Study supports using checklist over OSATS GRS for assessing preclinical students on simulated models

🔍 Key Findings

• Dogs with W-shaped tracheal collapse (WTC) had significantly more stridor and labored breathing preoperatively than those with traditional collapse (TTC) (p < .0001 and p = .0419).
• WTC dogs were 12.1× more likely to require preoperative oxygen support than TTC dogs.
• All dogs (TTC and WTC) survived to discharge after CETP placement; no intraoperative deaths occurred.
• Postoperative laryngeal paralysis occurred in 5 dogs (7.2%), with similar rates between TTC and WTC groups.
• Recurrent tracheal collapse occurred in 3 dogs (1 TTC, 2 WTC), all requiring additional stenting.
• 36-month survival was 75.7% (TTC) and 90.9% (WTC), not statistically different.
• Multivariate analysis showed Yorkshire Terriers (HR = 19.3) and older age (HR = 1.35 per year) were significantly associated with reduced survival.
• CETP was safe and effective for WTC, despite more severe preoperative signs, offering a viable alternative to stenting.

🔍 Key Findings

• CESF with distraction osteogenesis restored elbow congruity and normalized aLDRA in skeletally immature dogs with PCDRP.
• Radial head subluxation was eliminated in all dogs, and elbow incongruity reduced significantly (from 6.1 mm to 0.3 mm, p <.01).
• Mean radial lengthening of 22.6 mm (∼11% of normal length) was achieved, but only 80% of recorded distraction translated to length gain.
• Major complications occurred in 2/12 dogs: one with permanent carpal contracture, one with radial fracture at wire tract.
• Minor complications (e.g., carpal pain, restricted extension, synostosis, pin tract issues) were noted in 10/12 dogs but generally resolved.
• Owner surveys (8/12 dogs) reported good to excellent long-term function, even up to 6 years post-op.
• Radial valgus deformities were moderate (mean 15°) and less severe than deformities from ulnar physeal closure.
• Surgical strategy included staged distraction, with radial or combined radius/ulna distraction guided by fluoroscopy and adjusted per case.

🔍 Key Findings

Design: In vitro study on cadaveric femurs (n=21) with basilar femoral neck fractures stabilized using 2 vs 3 titanium cannulated screws.

Stiffness: Control > 3-screw > 2-screw (674 > 120 > 90 N/mm).

Yield Load: 3-screw (586 N) > 2-screw (303 N); both < intact femur (2692 N).

Displacement: No difference across groups.

Complication: 3-screw technique more demanding; higher risk of cortical perforation, especially with narrow femoral necks.

Failure Mode: Dislodgement of femoral head + screw shaft bending.

Conclusion: 3 screws = stronger construct than 2 screws. Clinical implications need further study.

🔍 Key Findings

• Double pelvic osteotomy (DPO) significantly decreases dorsal acetabular rim angle (DARA), confirming improved acetabular ventroversion and femoral head coverage in dysplastic hips.
• The achieved acetabular ventroversion is consistently less than the plate’s predetermined angle, indicating predictable loss of rotation during DPO.
• Median reduction in DARA was 23.4°, 16.7°, and 15° with 30°, 25°, and 20° plates respectively, demonstrating that larger plates produce greater rotation but still less than intended.
• Actual ventroversion achieved was ~5–8° less than the plate angle, with median losses of 6.6°, 8.3°, and 5° for 30°, 25°, and 20° plates.
• Postoperative DARA decreased from ~16–18° preoperatively to approximately −4°, aligning with recommended postoperative acetabular slope targets.
• Postoperative DARA remained stable on short-term (~48 days) and long-term (~386 days) CT follow-up, suggesting minimal remodeling after DPO.
• Most acetabular rotation (~88%) occurs at the pelvic symphysis rather than through iliac torsion, explaining partial loss of rotation relative to plate angle.
• CT-measured DARA provides a reliable surgical planning metric and may improve implant angle selection for DPO procedures.

🔍 Key Findings

• Cricoarytenoid lateralization (CAL) resulted in a significantly greater increase in rima glottidis area at both immediate (205%) and 15-day (199%) time points compared to thyroarytenoid lateralization (TAL) (152% and 127%, respectively).
• TAL group showed a significant reduction in rima glottidis area between immediate and 15-day postoperative measurements (P < .05), while CAL group had no significant reduction over time.
• No dogs in either group showed postoperative complications, including aspiration pneumonia, at the 15-day follow-up.
• All dogs showed improved clinical signs, including decreased stridor and increased exercise tolerance by day 15.
• CAL produced more stable postoperative glottic area, potentially due to preserved anatomical tension, whereas TAL might experience tension loss due to thyroid cartilage repositioning.
• Both procedures were technically effective and performed under the same protocol by a single board-certified surgeon.
• Endoscopic image analysis was used to quantify rima glottidis area, demonstrating a reliable objective method for surgical outcome assessment.
• Clinical outcome did not differ between groups, despite CAL showing a larger rima glottidis area.

🔍 Key Findings

• Locked facet injuries in dogs involved unilateral dorsal displacement of the cranial articular process of the caudal vertebra, most commonly at C5/6 or C6/7.
• All affected dogs were small/toy breeds, typically following trauma (most often attacks by larger dogs).
• Neurologic severity ranged from ambulatory tetraparesis to tetraplegia, often with thoracic limb deficits more severe than pelvic limbs — suggesting a central cord syndrome-like pattern.
• CT and MRI revealed axial rotation, subluxation, and articular process displacement; MRI showed T2 hyperintensity, nerve root impingement, and soft tissue changes.
• Surgical treatment included ventral fixation with screws, pins, and PMMA, and one case required dorsal facetectomy for reduction.
• Medical management, including external coaptation or rest, also resulted in functional recovery in select cases.
• All dogs with follow-up data (8/8) had functional recovery, with nonambulatory dogs regaining ambulation in a median of 4 weeks.
• No consistent differences in outcome were observed between surgical and nonsurgical management, suggesting locked facets may be biomechanically stable.
