In Dickson 2024 et al., on VATS for feline chylothorax, what was the most common postoperative complication?
🔍 Key Findings
- Objective: To evaluate outcomes and complications of video-assisted thoracoscopic surgery (VATS) for idiopathic chylothorax in 15 cats.
- All 15 cats underwent thoracoscopic thoracic duct ligation (TDL); 13 also had simultaneous pericardectomy, 2 had VATS TDL + laparoscopic cisterna chyli ablation (CCA), and 1 cat had an open CCA.
- Median surgical time was 152.5 minutes (range 60–255).
- Contrast was used intraoperatively in 13 cats; 11 received methylene blue, and 2 received indocyanine green (ICG).
- One intraoperative complication (6%) occurred — a minor intercostal artery laceration. Conversion to open surgery occurred in 3 cases (20%) due to visualization issues or bleeding.
- Postoperative complications occurred in 8 cats (53%), with persistent pleural effusion in 5 cats (33%) being the most common.
- Mortality was high: 4 cats (27%) died or were euthanized before discharge. Only 7 of 11 cats discharged had resolution of effusion, and recurrence occurred in 1.
- Authors concluded that while VATS is technically feasible in cats, it did not improve clinical outcomes compared to open surgery, and feline idiopathic chylothorax continues to have a high mortality rate.

In Buote 2023 et al., on 3D-printed cannulas in feline laparoscopy, what was the estimated cost of a single 3D printed autoclavable cannula?
🔍 Key Findings
- 3D-printed cannulas (3DPCs) reduced mean surgical time significantly in cadaveric procedures (125.6 vs 95.2 min, p = 0.03).
- Cannula pullout events decreased from a mean of 10 to 2.2 per procedure when using only 3DPCs (p = 0.03).
- Instrument collisions were significantly fewer with 3DPCs (6.8 vs 2.6 collisions, p = 0.03).
- Live patients experienced no postoperative complications, including no incision site infections or discomfort.
- Initial versions of 3DPCs had minor issues, including valve leakage and looser trocar fit, requiring surgical workarounds.
- Customization of cannula shaft length (3 cm vs standard 5–8.3 cm) improved working space and reduced instrument interference.
- Production cost was under $5 per cannula, suggesting 3DPCs may be a cost-effective and reusable alternative for small patients.
- Study supports broader use of 3DPCs in laparoscopic procedures requiring long-jawed instruments or intricate tissue handling.

In Drudi 2022 et al., on CAL vs TAL outcomes, what was the approximate mean increase in rima glottidis area at 15 days post-op for the CAL group?
🔍 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.

In McCagherty 2025 et al., on WID detection accuracy, how did image-guided swabs compare to non-guided swabs in bacterial yield?
🔍 Key Findings
- Bacterial fluorescence was detected in all wounds (17 dogs, 4 cats) using the point-of-care wound imaging device (WID).
- The WID confirmed the presence of clinically relevant wound infection in all evaluated cases at the time of imaging.
- No significant difference was found in bacterial yield or burden between image-guided and non-guided swabs (QBC and PCR; p > 0.05).
- The WID helped guide wound debridement in some cases by localizing areas of fluorescence, especially in necrotic tissue.
- Most infections were polymicrobial and dominated by anaerobes, highlighting the need for anaerobic culture inclusion.
- PCR analysis showed low bacterial DNA yields, often complicated by host DNA contamination, limiting its utility.
- The study did not evaluate sensitivity/specificity of WID, as only fluorescence-positive wounds were included.
- Clinical utility of WID lies in immediate visual confirmation of infection, supporting timely antimicrobial treatment decisions.

In Lomas 2025 et al., on hybrid THR in cats, what postoperative complication was **not observed** in any of the 17 hips treated?
🔍 Key Findings
- Hybrid THR in cats showed no major complications across 17 hips in 15 cats, including 2 bilateral cases.
- Postoperative radiographs confirmed stable implant positioning with no loosening, migration, or dislocation in follow-up imaging.
- Mean owner satisfaction was high, with a mean short-form feline musculoskeletal pain index (sf-FMPI) score of 2/36 at a mean follow-up of 438 days.
- SCFE (slipped capital femoral epiphysis) was the most common indication, seen in 13/17 hips.
- Partial tenotomy of rectus femoris origin resolved intraoperative medial patella luxation in 3 cases—no cats required surgical correction later.
- A micro BFX cup allowed for increased acetabular offset, possibly reducing luxation risk even when using a +0 femoral head offset.
- Hybrid THR was successfully used as a revision for failed CFX THR due to recurrent luxation—implants remained stable post-revision.
- Use of oversized cups (12 mm) with shallow seating or medial breach still resulted in stable outcomes, suggesting good implant fixation even with reduced bone stock.

In Danielski 2022 et al., on PAUL complications, what did the study reveal about expert prediction of complications based on post-op radiographs?
🔍 Key Findings
- Major complications occurred in 25.6% of limbs treated with PAUL, including non-union, implant failure, and infection requiring revision surgery.
- Increased body weight was significantly associated with a higher risk of complications (7% increased risk per additional kg; p = .04).
- Post-operative radiographic assessment was unreliable in predicting complications; inter-observer agreement was poor (kappa ≤ 0.12).
- Expert evaluation of implant or reduction errors had low predictive value (k < 0.2) for postoperative complications.
- Common major complications included non-union (6 limbs), screw breakage, and surgical site infections.
- Implant removal was required in 11.5% of limbs, mostly due to non-union or infection.
- Being a Labrador appeared protective on univariate analysis, but not on multivariate analysis after adjusting for weight.
- Radiographs showing suboptimal plate placement or osteotomy reduction did not reliably correlate with actual complication occurrence.

In Pfund 2025 et al., on femoral cortical thickness, what was the observed effect of a 0.001 increase in CTI on fracture risk?
🔍 Key Findings
- Lower CTI values were significantly associated with higher risk of both intraoperative and postoperative femoral fractures or fissures (p <.0001).
- The mean CTI for all dogs was 0.285, whereas dogs with fissures/fractures had a mean CTI of 0.246.
- For each 0.001 increase in CTI, odds of fissure/fracture decreased by 2–3% depending on perioperative timing.
- High interobserver reliability (ICC = 0.984) and consistency between pre- and postoperative CTI measurements (ICC = 0.96).
- CTI was the only significant risk factor identified; age, breed, bodyweight, BCS, CFI, or luxoid hips were not significant.
- Prophylactic lateral plating in dogs with low CTI (mean 0.230) resulted in no postoperative fractures.
- Postoperative fractures occurred in 8% of cases, and 93% of dogs returned to full function within one year.
- CTI may be a useful radiographic screening tool, especially when advanced imaging (e.g., DEXA) is unavailable.

In Deprey 2022 et al., on gap fracture implants, which construct had significantly lower axial deformation in compression testing?
🔍 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.
