🔍 Key Findings

• Surgical management significantly improves survival vs medical therapy, with MST ~1942d vs 567d (p = .028), supporting intervention over conservative care.
• DOV occlusion achieves superior initial occlusion rates (95% vs 56% for TAE; p = .007), making it more reliable for immediate flow cessation.
• TAE has significantly higher recurrence rates (53% vs 15% for DOV; p < .001), often requiring repeat procedures.
• Residual HAVM flow is more common after TAE (44% vs 5%), reflecting difficulty targeting the nidus via arterial routes.
• Overall survival time between TAE and DOV is not significantly different, but more DOV patients remain alive at follow-up (55% vs 11%; p = .003).
• Quality of life outcomes favor DOV, with 78% “excellent” vs 27% in TAE (p = .018).
• Multiple arterial supply sources (e.g., gastric, phrenic, intercostal arteries) complicate complete embolization and contribute to recurrence (Figure 6, page 17).
• Restoration of hepatopetal portal flow is a key success indicator, particularly after DOV occlusion (page 16 discussion).

🔍 Key Findings Summary

• No significant difference in mechanical properties between contoured vs non-contoured SOP-LC rods
• Clamp configuration significantly influenced mechanical performance:
  • Single-side clamps → ↑ yield load, ↑ displacement, ↑ bending strength (p < 0.05)
  • Alternating-side clamps → ↑ initial torsional stiffness (p = 0.029)
• Clamp slippage was evident only in torsional tests; screw loosening may be torque-dependent
• Mild screw bending and construct offset suggest subtle instability
• Recommends clamp configuration choice based on loading scenario
• Suggests 3.0 Nm torque may be more effective than 2.5 Nm to prevent clamp slippage

🔍 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.

🔍 Key Findings Summary

• Population: 35 nonbrachycephalic dogs undergoing orthopedic procedures (TPLO)
• Study design: Prospective observational using transnasal Digitrapper dual-sensor pH probe after short TIVA
• Upper reference limits:
  • Distal GER events per hour: 2.4
  • Proximal GER events per hour: 0.4
  • Cumulative distal acid exposure: 2.3%
  • Cumulative proximal acid exposure: 0%
• Median values (normal):
  • Distal GER events per hour: 0.3
  • Proximal GER events per hour: 0
• Proximal GER observed in 12/31 dogs
• No regurgitation observed in any dog
• No major adverse events with probe use
• Clinical implication: These parameters provide a reference for assessing excessive GER in future canine surgical cases

🔍 Key Findings

• WMg (water manometer with gauge) was the most accurate and precise pressure measurement device.
• APT (arterial pressure transducer) was less accurate than WMg but still precise; it differed significantly from the gold standard (WMr).
• CCT (Compass CT) was the least accurate and precise and differed significantly from the set pressure.
• Mean differences from set pressure were smallest for WMg (−0.020 cm H2O), moderate for APT (−0.390 cm H2O), and largest for CCT (−1.267 cm H2O).
• All devices showed excellent interobserver (ICC = 1.000) and intraobserver agreement (ICC range 0.985–0.998).
• Even though the CCT performed least well, all devices had mean errors ≤1.3 cm H2O, indicating potential clinical utility.
• WMg or WMr should be preferred in surgical settings due to superior accuracy and precision.
• Measurement precision is more critical than accuracy during PSS surgery, as a 1 mm Hg (~1.3 cm H2O) increase in portal pressure raises odds of poor outcomes by 9%.

🔍 Key Findings

• 3D-printed TPLO guides significantly reduced osteotomy inclination angle in both bone models and cadaver limbs compared to jig alone (P < .001).
• Torsional deformities were lower when the 3D-printed guide was used in bone models (P < .001), but not significantly different in cadavers.
• Angular deformities were significantly reduced in cadavers using 3D-printed guides (P < .001).
• Proximal jig pin angulation was more accurate with the guide in cadavers (P < .001); not significant in bone models.
• Medial cortex damage was substantially reduced in bone models when the 3D-printed guide was used (P < .001).
• Postoperative tibial plateau angle (TPA) did not differ significantly between groups, suggesting that clinical alignment can still be achieved without the guide.
• Clinical significance of improved metrics is uncertain, but improved precision may reduce surgical complications.
• 3D guide design allowed direct placement of jig and bone plate, potentially improving workflow and safety.

🔍 Key Findings Summary

• Lateral humeral condylar fractures = 69.8% of cases; medial = 16.2%; Y/T = 14.0%
• Falls/stairs were the inciting trauma in 45.6% of cases; significantly younger dogs were more likely to fracture after major trauma (p = 0.01)
• Complication rate = 22% (10 major, 20 minor); implant migration and seroma most common
• Fixation method had no significant impact on complication rates (p = 0.87)
• Epicondylar comminution was significantly associated with complications (p = 0.02, OR = 3.27)
• Contralateral intracondylar fissure found in 9.8%, none progressed to fracture during study
• Wide inter-center variation in complication rate (5–62%, p = 0.002)

🔍 Key Findings

• Study Design: Retrospective case series of 15 dogs (19 tarsi) with talar OCD.
• Technique: Modified arthroscopic approach with both scope and instrument portals on the same side as the lesion.
• Outcomes:
  • Good to excellent mid-to-long-term outcomes in 11/14 dogs.
  • Statistically significant improvement in CBPI (p < .05) and VAS scores (p < .05).
  • Minor postoperative complications (synovial cysts) in 4/13 tarsi, all resolved spontaneously.
  • No major intraoperative complications; 1/19 required mini-arthrotomy due to fragment size.
• Degenerative Joint Disease (DJD): Progression noted in 10/14 cases, despite good functional outcomes.
• Fragment Characteristics: Multiple osteochondral fragments were present in most cases, with 17/19 lesions on the medial talar ridge.
• Technical Advantage: Lower conversion rate to arthrotomy (1/19) compared to previous studies (Gielen et al. and Miller & Beale).

🔍 Key Findings

Population: 24 dogs (<8.5 months) undergoing unilateral cementless THR.
Growth Impact:

• Operated femurs showed ~11.5% less trochanteric growth than controls (p = .002).
• No significant difference in femoral diaphyseal + epiphyseal length (p = .712) or femur overall (p = .465).

Cortical Width:

• Increased significantly at 10 mm distal to trochanter (4.6% increase, p = .037) and at 50% femoral length (8.5% increase, p = .030).

Clinical relevance: Despite measurable changes, no clinically significant impairment to femoral length occurred.
Effect Sizes:

• Moderate negative for trochanteric growth.
• Moderate positive for proximal femoral width.

🔍 Key Findings Summary

• IMN provides relative stability, resists bending/torsion due to central axis alignment
• Larger diameter nails = exponentially greater stiffness (∝ D⁴)
• Trade-off: Larger interlocking holes weaken fatigue strength of the nail
• Reaming increases contact/stability but has pros/cons:
  • Improves outcomes in closed fractures
  • May reduce endosteal blood flow in thin-walled bones (e.g., cats)
• Design advances:
  • Angle-stable IMN reduce rotational slack
  • Expandable nails simplify insertion but may compromise removal or compressive load resistance
  • Precontoured nails match bone curvature but lack consistent clinical superiority
• Material debates continue (e.g., titanium vs. stainless steel vs. magnesium)
