In Ritson 2025 et al., on feline hilar lobectomy sealants, what was the **main advantage** of PLL and DS clips over traditional staplers in cadaveric models?
🔍 Key Findings
- No leakage occurred using pretied ligature loops (PLL) or double-shank (DS) titanium clips up to 40 cm H₂O airway pressure.
- 1/10 stapled lobes leaked at supraphysiologic pressure (40 cm H₂O), but this was not statistically significant (p = .33).
- All techniques sealed effectively under physiologic and supraphysiologic pressures in cadaveric feline lungs.
- PLL and DS clips required less working space than staplers, making them more practical for small thoracic cavities.
- DS titanium clips offer enhanced security due to dual shanks and tissue-gripping design, reducing clip slippage.
- Leak testing was cyclic and submerged, simulating physiologic ventilation and allowing robust evaluation.
- Stapling failure occurred along the staple line, highlighting risks of air leakage due to staple misalignment or poor hilar access.
- PLL and DS clips may be cost-effective and efficient alternatives for open or minimally invasive feline lung lobectomy.

In Kuvaldina 2023 et al., on axillary lymph node excision, what was the reason for conversion to an open approach in one clinical case?
🔍 Key Findings
- Endoscopic excisional biopsy of axillary lymph nodes was successfully performed in cadavers and clinical dogs with minimal complications.
- The technique used a SILS port and CO₂ insufflation through a small incision between the latissimus dorsi and superficial pectorals.
- In 4 cadavers (6 limbs), mean time to remove axillary nodes was 33 minutes, and single nodes were found in 5/6 limbs.
- In 3 clinical dogs, the procedure was successful in 2 cases; 1 required conversion to open surgery due to difficulty manipulating the node.
- Accessory axillary nodes were successfully excised when present, located adherent to deep latissimus dorsi.
- No cases developed lymphedema, pneumothorax, or major complications postoperatively.
- Subjective benefits included better visualization, reduced dissection, and less postoperative morbidity than open techniques.
- Study suggests MIS lymphadenectomy may improve staging accuracy and reduce complications, though larger studies are needed.

In Danielski 2024 et al., on PUO effect on HIF, what percentage of elbows demonstrated subjective partial or complete healing on follow-up CT?
🔍 Key Findings Summary
- Sample: 51 elbows from 35 spaniel dogs
- Healing Rate: Subjective healing (complete or partial) in 80.3% of elbows; complete in 54.9%
- Objective HU analysis: Mean HU increased from 640 (pre-op) to 835 (follow-up) (p = .001)
- Age Effect: Dogs <14 months showed the greatest HU increase (+384 HU) and had wider fissures with less sclerosis
- Complications:
- Major: 5 dogs (6 limbs); 4 related to fissure healing (7.8%), 2 related to PUO healing (3.9%)
- Minor: 3 cases (5.8%) due to IM pin migration
- Sclerosis: Older dogs had more humeral condyle sclerosis, possibly limiting healing
- PUO Effectiveness: Confirmed cranio-proximal displacement of anconeal process; aimed to relieve humero-anconeal incongruity
- Control Comparison: Avoids complications associated with transcondylar screw (infection, breakage)

In Kennedy 2024 et al., what strategy was recommended to minimize iatrogenic cartilage injury (IACI)?
🔍 Key Findings Summary
- 20 shoulders from 11 medium-to-large breed dogs evaluated
- Lateral portals used: middle arthroscopic, caudal instrument, cranial egress
- Musculotendinous lesions unavoidable, but small (18G needle); seen in deltoideus (90%), infraspinatus, teres minor, etc.
- Neurovascular safety:
- Caudal portal was closest to axillary artery/nerve branches (as close as 7 mm)
- Only 2/20 shoulders (10%) had omobrachial vein penetrated
- Cartilage injuries (IACI) occurred in 65%, primarily minor linear defects; use of guarded cannulas and distractors suggested for minimization
- Supports overall safety of lateral shoulder arthroscopy with portal placement awareness

In Wang 2025 et al., on TPLO osteotomy alignment, what was the primary benefit of using intraoperative fluoroscopy?
🔍 Key Findings
- Fluoroscopy-guided osteotomy placement achieved a median postoperative TPA of 3° (range: 0–4.5°), showing excellent accuracy.
- The D1 measurement (from patellar ligament insertion to osteotomy exit) was more reproducible and accurate intraoperatively than D2.
- Median R1 value (D1-based) matched the intended 21 mm radius with only 0.5 mm deviation, while R2 deviated by 2.5 mm.
- Real-time fluoroscopy allowed dynamic limb positioning and reduced osteotomy placement variability.
- Intraoperative fluoroscopy reduced reliance on preoperative planning, especially in cases with difficult anatomy or positioning.
- Radiation exposure was minimal (avg. 3 images per case) and within safe limits using standard protection protocols.
- Study standardized to 21 mm blades and excluded dogs with developmental orthopedic conditions to reduce confounders.
- Targeting a lower postoperative TPA (3°) may reduce meniscal load and cranio-caudal instability, though long-term outcomes require further study.

In Longo 2022 et al., on CT-guided osteotomies, what was the primary method used to intraoperatively determine the amount of rotational correction needed for torsional deformities?
🔍 Key Findings
- 3D CT volume rendering and CAL measurement successfully guided correction of femoral and tibial torsion in dogs with patellar luxation (PL).
- Physiological patellar tracking was restored in 100% (22/22) of cases after detorsional osteotomy.
- 94% of dogs (17/18) had either full or acceptable functional outcomes post-surgery.
- CAL-based correction was accurate in 19/22 cases, confirming reliability of the measurement technique.
- Complication rate was 45%, with major complications in 2/22 cases—both involved combined femoral and tibial osteotomies.
- Combined femoral and tibial osteotomies in the same limb were linked to a higher risk of complications and poorer outcomes.
- Diaphyseal osteotomies offered more implant space, but metaphyseal locations were associated with faster bone healing.
- Use of a TPLO jig or goniometer was not essential—CAL-based bone marking was sufficient in most cases.

In Williams 2024 et al., on adrenaline use in maxillary nerve blocks, what was the observed reduction in median intraoperative hemorrhage in the adrenaline group compared to the no-adrenaline group?
🔍 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.

In Gibson 2024 et al., on mediastinoscopy in dogs, what was the **overall complication rate** observed during the cadaveric procedures?
🔍 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.

In Thomsen 2024 et al., on CT accuracy for liver tumors, which liver lobes showed significantly lower CT localization accuracy?
🔍 Key Findings
- CT localization of liver masses was more accurate by division (88%) than by lobe (74.3%)
- Inter-radiologist agreement was excellent for division (kappa up to 0.885) and only moderate–good for lobe
- Quadrate and right lateral lobes had significantly lower localization accuracy compared to left lateral or medial lobes
- CT localization of the left division was most accurate (90.1%) compared to central (77.1%) and right (88.3%)
- Portal and hepatic venous phases were equally helpful for localization (each ~30–38% usefulness)
- No significant associations found between histopathologic diagnosis and localization accuracy
- Lobe-level CT localization should be interpreted with caution, especially for the quadrate and right lateral lobes
- Radiologist experience likely influenced accuracy, with the most experienced radiologist performing best

In Raleigh 2022 et al., on pericardiectomy complications, what was the approximate incidence of intraoperative ventricular fibrillation (VF)?
🔍 Key Findings
- Ventricular fibrillation (VF) occurred in 3% of pericardiectomy cases across reporting institutions.
- 14 of 16 dogs (88%) that developed intraoperative VF died, indicating high mortality.
- Electrosurgical devices were used in 15/16 dogs; VF onset coincided with their use in 8 dogs, suggesting a potential but unproven association.
- Preoperative arrhythmias were seen in 7 dogs (e.g., VPCs, VT, bradycardia), possibly serving as early warning signs.
- Thoracoscopic approach was used in 75% of cases; however, conversion to open surgery was required in 9/13 thoracoscopic procedures after VF onset.
- Defibrillation was attempted in 13 dogs, but only 3 converted to sinus rhythm, and only 2 survived postoperatively.
- VF may result from stray current or cardiac manipulation; bipolar energy devices were implicated despite lower theoretical risk.
- Preventative strategies include judicious electrosurgery use, close ECG monitoring, rapid CPR preparedness, and preop cardiac risk assessment.
