Quiz Question
In Canever 2022 et al., on labial flap vascular anatomy, what postoperative complication occurred in Case 1 that required management?
🔍 Key Findings
- Superior and inferior labial arteries in cats perfuse robust angiosomes, which support musculomucosal axial pattern flaps.
- Cadaver angiography confirmed vascular anatomy, with consistent patterns between sides and among specimens.
- The vascular supply is located primarily in the musculomucosal layer, not the skin, critical for flap viability.
- Flap harvest requires inclusion of the orbicularis oris (± buccinator) muscle to ensure vascular integrity and flap survival.
- Two clinical cases demonstrated successful use of superior and inferior labial musculomucosal flaps for palatal reconstruction with complete flap survival and resolution of clinical signs.
- Intraoperative transillumination aided vessel localization, facilitating surgical planning and flap design.
- No cases of distal flap necrosis or dehiscence occurred, although mild donor site morbidity (lip retraction, mucosal denuding) was noted.
- These flaps offer a valuable option when local tissues are compromised, especially after failed previous repairs or radiation therapy.

In Horwood 2024 et al., on complications in luxoid hip dysplasia, what was the most common surgical revision performed for dorsal luxation?
🔍 Key Findings
- Luxoid hip dysplasia (LH) was present in 8% of THA cases and significantly increased risk of major complications (p < .001).
- Intraoperative fissures/fractures were 3x more likely in LH dogs vs non-LH (39% vs 16%, p = .001).
- Dorsal luxation was more frequent in LH dogs (28% vs 4%, p = .019).
- Acetabular cup placement with ALO >35° was associated with luxation in LH dogs.
- Morphologic abnormalities (e.g., femoral valgus, lateralization/medialization of cortices) were common in LH and may complicate implantation.
- Despite higher risk, 94% of LH dogs achieved satisfactory outcomes after appropriate revisions.
- Younger age and lighter weight characterized LH dogs (mean age 14.7 months vs 40.9 months, p < .001).
- All LH dogs were treated with cementless stems; prophylactic cerclage was rarely used.

🔍 Key Findings Summary
- 16 dogs (18 stifles) with CrCL rupture and TPA >34° were treated using the DCTPLO

- Patellar ligament thickening seen in 16/18 stifles but no clinical signs noted
- The technique enabled safer reduction with less risk of tibial crest fracture vs. conventional TPLO

🔍 Key Findings Summary
- Sample: 124 dogs (64 S, 60 FFP); French Bulldogs most common (54/124)
- Pre-op clinical signs: Exercise intolerance (34/124), stertor (22), regurgitation (7), vomiting (12)

- Post-op regurgitation: 27/124 (S: 17, FFP: 10; p = .18)
- Post-op aspiration pneumonia: Rare (S: 4, FFP: 5)
- Major complications: Rare (5/124); 2 dogs euthanized post-op (1 per group)
- Revision surgery: Needed in 7/124 (3 S, 4 FFP)

In O'Marra 2026 et al., on perioperative septic peritonitis, which of the following is a recommended strategy to mitigate intra-abdominal hypertension in at-risk veterinary patients?
🔍 Key Findings
- Early enteral nutrition (<24–48 hrs) is associated with improved survival and reduced hospitalization in dogs with septic peritonitis.
- Appropriate empirical antimicrobials improve survival in cats, but data are mixed in dogs.
- Recurrent septic peritonitis (RecSP) has poor survival (0%–43.9%); most common cause is gastrointestinal dehiscence.
- Intraoperative hypotension and preoperative hypoalbuminemia may increase dehiscence risk, though findings are inconsistent.
- Lidocaine CRI during surgery improves survival over opioids alone in dogs.
- Hydroxyethyl starch (HES) is not recommended due to risks of coagulopathy and kidney injury; albumin use is controversial.
- Intra-abdominal hypertension (IAH) is under-recognized but contributes to mortality; IAP monitoring should be considered.
- Diagnostic tests (effusion lactate, glucose, cytology) are unreliable for detecting RecSP; clinical judgment and ultrasound are advised.

In Larose 2024 et al., on laparoscopic liver biopsies in dogs, what was the key clinical implication of using a 3 mm CBF in small dogs for liver biopsy?
🔍 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.

In Cruciani 2025 et al., on portal placement, which pain scoring tool showed significant postoperative improvement?
🔍 Key Findings
- Study Design: Retrospective case series of 15 dogs (19 tarsi) with talar OCD.
- Technique: Modified arthroscopic approach with both scope and instrument portals on the same side as the lesion.
- Outcomes:
- Good to excellent mid-to-long-term outcomes in 11/14 dogs.
- Statistically significant improvement in CBPI (p < .05) and VAS scores (p < .05).
- Minor postoperative complications (synovial cysts) in 4/13 tarsi, all resolved spontaneously.
- No major intraoperative complications; 1/19 required mini-arthrotomy due to fragment size.
- Degenerative Joint Disease (DJD): Progression noted in 10/14 cases, despite good functional outcomes.
- Fragment Characteristics: Multiple osteochondral fragments were present in most cases, with 17/19 lesions on the medial talar ridge.
- Technical Advantage: Lower conversion rate to arthrotomy (1/19) compared to previous studies (Gielen et al. and Miller & Beale).

In Welsh 2023 et al., on TTAF fixation methods, what was the estimated quadriceps force at a walk used as a benchmark for load testing?
🔍 Key Findings
- Two-pin fixation had significantly greater strength (639 N) than single-pin fixation (426 N) in TTAF models (p = .003).
- Stiffness was also higher with two-pin constructs (72 N/mm vs 57 N/mm); statistically significant (p = .029).
- Both fixation types withstood loads greater than quadriceps force in dogs at a walk (240 N), indicating clinical viability.
- Failure was most commonly due to pin bending or pullout (82%), with fewer cases of ligament tearing or epiphyseal fracture.
- K-wire insertion angle (KWIA) did not significantly differ between fixation types (p = .13).
- Single larger pins delivered ~68% of the strength and ~83% of the stiffness of two smaller vertically aligned pins.
- Clinical implication: Two vertically aligned pins are biomechanically superior for TTAF fixation in canine models.
- Study used mature cadavers, which may underestimate loads and stiffness compared to immature clinical cases.
