🔍 Key Findings

• TPLO with the contoured saw guide achieved more accurate osteotomy angles for both inclination and torsion in bone models and cadaveric limbs (p < .05).
• Medial cortical damage was significantly lower with the contoured guide (247 vs. 1866 pixels in bone models; p < .001).
• No significant difference in eccentricity (distance between actual and intended osteotomy center) was found between groups.
• Postoperative tibial plateau angle (TPA) was similar between groups (6.4° vs. 7.6°; p = .15), though both were slightly higher than the target of 6°.
• Deviation in medial mechanical proximal tibial angle (mMPTA) showed no significant group difference; valgus deformity occurred in both.
• Osteotomy and device application times were similar between the contoured guide and jig-assisted TPLO.
• The contoured guide eliminated the need for proximal jig pin, potentially reducing intra-articular pin risk.
• The guide's multiple pin fixation system improved stability and alignment, supporting safer osteotomy on curved tibial surfaces.

🔍 Key Findings

• Ventricular fibrillation (VF) occurred in 3% of pericardiectomy cases across reporting institutions.
• 14 of 16 dogs (88%) that developed intraoperative VF died, indicating high mortality.
• Electrosurgical devices were used in 15/16 dogs; VF onset coincided with their use in 8 dogs, suggesting a potential but unproven association.
• Preoperative arrhythmias were seen in 7 dogs (e.g., VPCs, VT, bradycardia), possibly serving as early warning signs.
• Thoracoscopic approach was used in 75% of cases; however, conversion to open surgery was required in 9/13 thoracoscopic procedures after VF onset.
• Defibrillation was attempted in 13 dogs, but only 3 converted to sinus rhythm, and only 2 survived postoperatively.
• VF may result from stray current or cardiac manipulation; bipolar energy devices were implicated despite lower theoretical risk.
• Preventative strategies include judicious electrosurgery use, close ECG monitoring, rapid CPR preparedness, and preop cardiac risk assessment.

🔍 Key Findings

PL-30 group (partial, TA30-V3 wedge):

• 100% leaked
• Median leakage pressure: 10 cm H₂O
• Most failures from periphery of staple line

PL-60 group (partial, TA60-3.5):

• 100% leaked
• Median leakage pressure: 18 cm H₂O
• Better than PL-30 (p = .006)

TL-30 group (total, TA30-V3):

• Only 1 of 11 leaked (at 22 cm H₂O)
• All others resisted pressures >50–65 cm H₂O
• Significantly higher leakage pressure than both PL groups (p < .001)

Odds ratios (leakage vs TL-30):

• PL-30: OR 437 at both 20 and 30 cm H₂O (p = .003)
• PL-60: OR 437 at 20 cm H₂O and 133 at 30 cm H₂O (p = .003)

Recommendation: Prefer TL-30 when possible. If partial needed, PL-60 superior to PL-30, but all partials leaked at physiologic pressures.

• 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

• 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.

🔍 Key Findings Summary

• Study of 24 stifles in 22 dogs with concurrent CCLR and grade III–IV MPL treated via TPLO-TTT
• Major complications: 4/24 (3 surgical site infections, 1 MPL reluxation); minor complications: 5/24
• Long-term follow-up (median 27 months): 21/22 dogs sound, 23/24 stifles resolved
• Patellar ligament thickening observed post-op in 4 cases, resolved with rehab
• The only case of MPL reluxation involved untreated tibial torsion, suggesting case selection is critical

🔍 Key Findings

• Laparoscopic cholecystectomy (LC) was successfully performed in all 22 cats without conversion to open surgery.
• Complication rate was low: 3 cats had postoperative complications (1 seroma, 1 vomiting, 1 EHBDO and death).
• Median operating time was 41 minutes; median hospitalization was 3 days.
• No cases required conversion to open laparotomy, even in cats as small as 2.5 kg.
• Common devices used: Hemoclips or Hem-o-lok for cystic duct ligation; Ligasure, harmonic scalpel, or j-hook for dissection.
• Most common indications: cholelithiasis (9/22) and cholecystitis (10/22), with one biliary mucocele and one adenoma.
• Histopathology confirmed diagnosis in all cases; concurrent liver or intestinal biopsies were performed in some cats.
• Postoperative AUS and bloodwork were routine and important for detecting early signs of EHBDO.

🔍 Key Findings Summary

• Used VMBDmD to quantify hip laxity under increasing force in cadaveric dogs (n=34).
• 90% of hips reached ≥90% of LImax at 95.32 N, defining this force as sufficient for subluxation.
• LImax was not significantly influenced by osteoarthritis, weight, sex, or limb side.
• Position of device (lever length) influenced rate of laxity acquisition, not final LImax.
• LI curves were repeatable across 5 sessions, indicating elastic—not plastic—deformation.
