In Clough 2022 et al., on CBLO-TTT construct testing, what is the clinical implication of combining CBLO and TTT?
🔍 Key Findings
- Combined CBLO-TTT did not reduce load to failure compared to CBLO or TTT alone (P = .81 and P = .12, respectively).
- CBLO-TTT maintains construct strength without significant compromise compared to individual procedures.
- Most common failure mode in CBLO-TTT was displacement of the tibial crest segment with k-wire pullout and tension band untwisting.
- No fulcrum effect was seen in CBLO-TTT, unlike TPLO-TTT combinations, likely due to preservation of buttress effect.
- Patellar ligament avulsion occurred in both CBLO and CBLO-TTT, but not as a clinical concern — possibly artifact from cadaver model.
- Load-to-failure testing was static and unidirectional, not accounting for cyclic fatigue or in vivo healing.
- Plate size and saw blade variation were based on clinical realism, introducing potential variability but not affecting outcomes.
- Study suggests feasibility of simultaneous surgical correction of CCL rupture and MPL using CBLO-TTT in dogs.

In Enright 2022 et al., on adrenalectomy outcomes, what was the observed effect of preoperative alpha-blocker therapy on long-term survival?
🔍 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.

In Winston 2023 et al., on LES-AS surgery outcomes, which preoperative treatment was discontinued postoperatively in all dogs?
🔍 Key Findings
- Modified Heller myotomy with Dor fundoplication improved vomiting/regurgitation scores by 180%, QoL by 100%, and owner-perceived body weight by 63% (P < .05).
- 6 of 9 dogs with postoperative VFSS showed objective improvement in gastric filling scores; others remained stable.
- Oral sildenafil was discontinued postoperatively in all dogs, indicating surgical success comparable to medical management.
- 12 of 13 dogs survived to discharge; one dog was euthanized due to aspiration pneumonia postoperatively.
- 50% of dogs experienced gastrostomy tube complications, higher than reported in previous literature.
- Most complications were gastrostomy-tube related, with some requiring surgical correction (e.g., tube migration, leakage).
- Feeding strategies (Bailey chair, elevated bowls) and food consistency (gruel/liquid) remained essential postoperatively to control regurgitation.
- 9 of 11 owners would opt for the surgery again; those who wouldn’t cited risk or lack of efficacy.

In Lhuillery 2022 et al., on GDV stabilization timing, which preoperative intervention was key to enabling delayed surgery without compromising outcomes?
🔍 Key Findings
- Survival rates did not differ between immediate (90 min) and delayed (≥5 h) surgical stabilization groups at discharge or 1-month post-op (approx. 80% survival in both).
- Hyperlactatemia at 24 hours post-fluid therapy was significantly associated with in-hospital and 1-month mortality (P = .01 and P = .02).
- Persistent tachycardia during hospitalization was linked to increased 1-month mortality (P = .015).
- Partial gastrectomy was required in ~6–10% of cases, with high associated mortality.
- Preoperative stabilization protocols (trocarization, nasogastric tube) allowed safe surgical delays up to 13.7 hours without impacting survival.
- Degree of gastric torsion differed between groups; more 0° torsions in delayed cases, potentially due to decompression-induced derotation.
- No difference in post-op complications such as arrhythmias, hypotension, or AKI between groups.
- More intra-anesthetic deaths occurred in immediate surgery group, highlighting importance of adequate pre-op stabilization.

In Socha 2024 et al., what is a clinical implication of UTE MRI for stifle evaluation in dogs?
🔍 Key Findings Summary
- Normative ultrashort echo time (UTE) MRI T2* values were established for:
- Patellar ligament (PL): T2*L = 4.65 ms
- Cranial cruciate ligament (CrCL): T2*L = 5.99 ms
- Caudal cruciate ligament (CdCL): T2*L = 7.06 ms
- Statistically significant differences in T2*L values were found between:
- PL vs. CrCL (p = 0.03)
- PL vs. CdCL (p = 0.0097)
- CrCL vs. CdCL (p = 0.03)
- No significant differences in short T2* (T2*S) values across ligaments.
- Study highlights potential of UTE MRI to detect early ligament changes even without physical instability.
- May guide early diagnosis in partial CrCL rupture where standard MRI is limited.

In Healy 2025 et al., on incidental PBBs, what recommendation is made regarding prophylactic lung resection?
🔍 Key Findings
Population: 2,178 canine CTs reviewed retrospectively.
Prevalence: Incidental PBBs found in 1.37% (30/2178).
Outcome: None of the dogs with incidental PBBs developed clinical spontaneous pneumothorax (SP) over a median follow-up of 1255 days.
Significant Associations:
- Age: Dogs with PBBs were significantly older (median 10.5 yrs vs. 8.2 yrs, p = .001).
- CT indication: PBBs more likely during neoplastic staging (p = .006).
PBB Characteristics:
- Total = 60 PBBs (median 1/dog; range 1–7).
- Location: 35% in left caudal, 31.6% right caudal, only 13.3% in right cranial lobe.
- Size-based: 25 bullae (>10 mm), 35 blebs (≤10 mm).
Conclusion: Prophylactic resection of incidental PBBs not justified given no observed SP risk in this population.

In Woelfel 2022 et al., on cervical locked facets, what was the most consistent outcome in dogs with follow-up?
🔍 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.

In Antonakakis 2022 et al., on telovelar tumor resection, how long did the dog remain neurologically normal after surgery?
🔍 Key Findings
- Telovelar approach enabled complete resection of a fourth ventricle choroid plexus tumor in a dog without postoperative complications.
- Postoperative MRI confirmed gross total tumor removal, and the dog remained neurologically normal 28 months post-surgery.
- The tela choroidea was used as a surgical landmark and incised to allow atraumatic access to the tumor.
- Cerebellum was spared using this technique, minimizing risk of cerebellar injury (e.g., cerebellar mutism).
- No hemorrhagic complications were noted during surgery due to dissection through avascular planes.
- Histopathology favored choroid plexus carcinoma based on mitotic index (9/10 HPFs), though definitive diagnosis remained pending.
- The case highlights the utility of telovelar over transvermian approach, given its minimally traumatic nature and improved exposure.
- Survival beyond 2 years without adjunctive therapy suggests surgical excision alone may be curative in select cases.

In Kalmukov 2022 et al., on cell salvage efficacy, what was the mean percentage of red blood cell mass (rbcM) recovered using direct suction?
🔍 Key Findings
- Direct suction salvaged more red blood cell mass (rbcM) than swab washing: 88.43% vs 84.74% (p = .015)
- Swab washing still achieved high recovery (84.74%), making it a viable adjunct when suction is not possible
- No significant difference in post-salvage PCV between methods (~34% for Su and ~33.9% for Sw)
- Total salvaged blood volume was significantly higher using direct suction (143 mL vs 139.8 mL; p < .001)
- Leukocytes are removed during salvage, potentially lowering risk of cytokine-mediated transfusion reactions
- Expired pRBCs were used, but device still achieved high RBC recovery, supporting clinical utility
- Swab washing via manual agitation may cause more RBC destruction than direct suction
- Cell salvage may avoid complications of allogeneic transfusions, like storage lesions and immunologic reactions

In Song 2024 et al., on CT vs cystoscopy for ectopic ureters in dogs, what percentage of dogs with normal ureters were missed by CT?
🔍 Key Findings
- CT correctly identified ectopic ureters in 91% of dogs, but missed 50% of normal ureters, limiting its negative predictive value.
- Sensitivity for intramural ectopic ureters was 65%, while specificity was 71%, indicating moderate diagnostic performance.
- Sensitivity for extramural ectopic ureters was only 29%, despite a high specificity of 97%.
- CT was inaccurate in predicting ureteral orifice location, with sensitivity ranging from 0% to 76% depending on the site.
- 26% of dogs were misclassified for cystoscopic laser ablation (CLA) eligibility based on CT findings alone.
- Overall CT accuracy for CLA candidacy was 74%, but a significant minority would have been inappropriately treated.
- Multivariate analysis found no predictive factors (e.g., colon distension, body weight) for when CT would be incorrect.
- Authors recommend confirmatory cystoscopy to verify CT findings prior to treatment planning.
