🔍 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.

🔍 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.

🔍 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

🔍 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.

🔍 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.

🔍 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.

🔍 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.

🔍 Key Findings

• No significant difference in initial leak pressure (ILP) among TA 30 V3 2.5 mm, TA 60 3.5 mm, and TA 60 4.8 mm stapler sizes (P = .78).
• All stapler types exceeded the physiological intraluminal pressure threshold (~25 mmHg), suggesting acceptable leak resistance.
• Mean ILPs: TA 30 V3 (181.5 mmHg), TA 60 3.5 mm (112 mmHg), TA 60 4.8 mm (77.2 mmHg).
• Leakage occurred at the staple line in 23 of 24 specimens; only one had ileal wall rupture.
• No correlation found between ILP and cadaver weight, cecal wall thickness, or cecal length.
• Cecal wall thickness averaged 4.9 mm, yet staple heights ranged only from 1.0–2.0 mm.
• One specimen in each TA 60 group leaked near or below physiologic pressures, suggesting rare outliers.
• Study supports clinical viability of all tested stapler sizes for canine typhlectomy, but highlights need for in vivo data on healing and complications.

🔍 Key Findings

• Low-trauma events caused 82.9% of CvHL cases; Poodles and poodle-crosses represented 49.4% of cases.
• Success rate of hobbles (61.8%) was significantly higher than closed reduction alone (10.3%) or Ehmer sling (18.5%).
• Multivariate analysis found hobbles 7.62x more likely to succeed vs. closed reduction (p = .001).
• Specialist surgeons had higher success with nonsurgical management (OR: 2.68; p = .047).
• Older age associated with better outcomes (OR: 1.15 per year; p < .0005).
• Ehmer sling is not recommended due to high failure and complication rates (60.6%).
• Toggle rod stabilization had a high surgical success rate (88.2%) with low complication.
• No link was found between CvHL and hip dysplasia or OA in most cases (only 2/108 showed OA).

🔍 Key Findings

• Dorsal scrotal arteries, branching from the ventral perineal arteries, are the dominant arterial supply to the scrotum in dogs.
• The ventral scrotal arteries, arising from the external pudendal arteries, perfused only the cranial scrotal border and were inconsistently present or absent in some dogs.
• A scrotal flap based on the dorsal scrotal arteries showed strong perfusion and may be a viable axial pattern flap.
• Perfusion was consistent across fresh and frozen cadavers, showing no difference due to preservation method.
• Poor flap survival (27%) occurred when based on cranial supply alone (i.e., ventral scrotal arteries), confirming importance of preserving caudal supply.
• There are anastomoses between dorsal and ventral scrotal arteries, offering collateral flow but insufficient alone for complete perfusion.
• Scrotal flaps based on the caudal pedicle may be applicable for reconstruction of proximal medial/lateral thigh wounds.
• Proposed flap requires careful preservation of ventral perineal arteries, ideally designed 2.5–3 cm lateral to midline in large dogs.
