🔍 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

50 dogs underwent bilateral anal sacculectomy using a modified closed technique.
Intraoperative anal sac perforation occurred in 5 dogs (10%), with no postoperative complications in those dogs.
Postoperative complications (43 dogs with follow-up):

• Grade 1 (e.g., scooting, inappropriate defecation): 14/43 (32%)
• Grade 2 (medical treatment needed): 2/43 (5%)
• Grade 3B (revision surgery): 2/43 (5%)

93% of grade 1 and 100% of grade 2–3B complications resolved by two weeks postop.
Technique highlights: direct duct tracking, no anal sac packing, minimal dissection.

🔍 Key Findings

• No statistically significant difference in overall SSI rates: 9.2% (chlorhexidine) vs. 7.38% (iodophor) (p = .25).
• Significant drape lift occurred in 13.2% of cases; those with lift had 2.72× increased risk of SSI (p = .026).
• Increased body weight was a statistically significant risk factor for SSI (p = .008): each 1 kg increased SSI risk by 3%.
• Use of glutaraldehyde was associated with a 2.38× increased risk of SSI (p = .055, approaching significance).
• No difference in SSI rates based on surgeon training level or surgical classification (clean, clean-contaminated, contaminated).

🔍 Key Findings

• Needle arthroscopy (NA) had 95% sensitivity and 100% specificity for diagnosing medial meniscal tears in dogs with CCLR.
• NA missed 1 medial and 1 lateral meniscal tear, both nondisplaced and stable.
• Visibility of all meniscal horns was significantly lower with NA compared to standard arthroscopy (SA) (P < .005 for all horns).
• Probing the caudal horn of the lateral meniscus was significantly more difficult with NA (P = .0017), though medial horn probing was similar.
• Mean NA procedure time was 8 ± 3 minutes, significantly shorter than SA (15 ± 9 min, P = .0041).
• No increase in lameness observed after NA, indicating minimal procedural morbidity.
• NA was performed under sedation in most dogs, though 10/26 required additional chemical restraint or short anesthesia.
• NA was most accurate for displaced vertical longitudinal tears, with all 14 correctly identified; one stable tear and a lateral tear were missed.

🔍 Key Findings

• NIRF altered surgical strategy in 3 of 20 GDV dogs, identifying necrosis not appreciated subjectively.
• Fundic fluorescence <10% indicated histologically confirmed gastric necrosis.
• In 1 dog, NIRF revealed nonviability despite the surgeon’s impression of viability.
• Staple line fluorescence resembled viable tissue in the only stapled gastrectomy, suggesting preservation of perfusion.
• GDV dogs (even “viable”) showed lower fluorescence vs. healthy controls, indicating subclinical vascular compromise.
• Histology confirmed full-thickness necrosis in all 4 dogs with NIRF-defined nonviability.
• Pre-op lactate was significantly higher in nonviable GDV dogs (8.55 vs 4.89 mmol/L, p=0.03).
• No complications were reported from ICG use; imaging was safe and repeatable.

• Median survival time (MST) after surgery was 1886 days, which is significantly longer than previously reported.
• Lymph node metastasis at surgery was a negative prognostic factor, reducing MST to 248 days (vs. 2340 days without nodal involvement).
• Local recurrence occurred in 42% of dogs, with a median disease-free interval (DFI) of 191 days.
• Metastatic disease occurred in 32% of dogs, most commonly to the lungs, with a median DFI of 299 days.
• Histologic features (e.g., margin status, capsular, lymphatic, or vascular invasion) were not significantly correlated with recurrence or metastasis.
• Facial nerve injury occurred in 9.7% perioperatively, especially after parotidectomy; intraoperative facial nerve transection led to long-term deficits.
• Adjuvant therapies (chemotherapy, radiation, NSAIDs) did not significantly affect survival time.
• Incisional biopsy was only 38% concordant with final excisional histology, suggesting limited reliability for definitive diagnosis.

🔍 Key Findings

• Histologic agreement between 3 mm and 5 mm biopsies was 90%, with a Gwet's AC1 of 0.81 (p < .0001).
• 5 mm biopsies yielded significantly more portal triads and lobules than 3 mm samples (p = .0003 and p < .0001).
• Crush artifacts were significantly higher in 3 mm samples (p = .035), though fragmentation scores were similar (p = .935).
• Both forceps produced adequate samples for histopathology, copper quantification, and bacterial culture.
• No hemorrhage requiring intervention occurred, and both sizes were deemed safe and minimally invasive.
• Surface area ≥40 mm² strongly predicted ≥11 portal triads, a desirable threshold for reliable histopathology.
• Use of 3 mm instruments was easier in small dogs (<12 kg), but more challenging in larger dogs due to shaft length.
• Clinical diagnoses were unaffected by forceps size, even in the one discordant histologic pair.

🔍 Key Findings

• Dorsoventral radiographs artificially increase Norberg angle values by 3.2–5.8% and should be excluded.
• Lateral pelvic tilt >2° causes asymmetric changes in Norberg angle; >3° results in significant side-specific changes.
• Cranioventral-to-caudodorsal tilt >10° results in obvious radiographic tilt, but changes Norberg angle by only ~2%.
• Tilted but subjectively acceptable images have minor impact and may still be usable for screening.
• Norberg angle readings differed consistently between left/right hips — possibly due to operator handedness.

🔍 Key Findings

• Modified subdural shunt (SDS) placement was adapted from prior techniques using a hemilaminectomy approach and no suturing of the dura or shunt.
• Dogs receiving SDS had significantly better long-term outcomes (85.7% improved) compared to those with durotomy alone (41.7%).
• Recurrence rate was lower in the SDS group (14.3%) than control (41.7%), though not statistically significant.
• Most recurrences occurred in Pugs (5/7), suggesting a breed predisposition.
• Shunt size was limited to 25% of spinal cord diameter, typically 3–3.5 Fr.
• CSF flow through the shunt was confirmed intraoperatively, supporting the role of SDS in maintaining flow and possibly preventing recurrence.
• Immediate postoperative outcomes were not different between groups (≈42% deteriorated), but long-term recovery was better with SDS.
• Steroid use pre-surgery did not correlate with improved outcome; fewer SDS dogs received steroids pre-op.
