- Abstract
Objectives: The aims of this study are to describe a computed tomographic (CT) measurement method of feline femoral, tibial, and patellar conformation, and to compare these measurements between a cat population diagnosed with medial patellar luxation (MPL) and cats without MPL., Materials and Methods: Eleven measurements were performed by two observers, including anatomical lateral distal femoral angle (aLDFA), femoral trochlear width (FTW) and femoral trochlear depth (FTD), anteversion angle of the femoral neck, patellar length, patellar width, patellar height, patellar volume, mechanical medial proximal tibial angle, tibial torsion angle, and tibial tuberosity displacement. Mean and standard deviation differences between the groups were statistically assessed. Intraobserver and interobserver interclass correlation coefficients (ICCs) were calculated., Results: The aLDFA was significantly higher in the MPL II compared with the control and MPL III. The FTW was significantly larger in the MPL III than in the control or the MPL II group. The FTD in the control group was significantly larger than in the MPL II and III groups. The TTA of the control group was significantly smaller than the MPL II and III. The intraobserver ICC was high at 64%, and the interobserver ICC was high at 36% of the measurements., Clinical Significance: This study identified shallower FTD and increased TTA in cats diagnosed with MPL. The TTA difference was less than 5 degrees and FTD was less than 1 mm. The findings provide information on feline pelvic limb morphology. However, the differences between the two populations are small., Competing Interests: None declared., (Thieme. All rights reserved.)

- Abstract
The prevalence of anatomical-based subtypes of feline congenital extrahepatic portosystemic shunts (EHPSS) has not been completely elucidated. The goal of this study was to use CT angiography to create an anatomical-based nomenclature system for feline congenital EHPSS. Additionally, subjective portal perfusion scores were generated to determine if intrinsic portal vein development was associated with different shunt conformations or patient age at the time of CT. The SVSTS and VIRIES list services were used to recruit cases. Data collected included patient DOB, gender, breed, weight, CT date, and reported diagnosis. Shunts were classified based upon (1) the shunt portal vessel(s) of origin, (2) the shunt systemic vessel(s) of insertion, and (3) any substantial portal vessels contributing to the shunt. Additionally, hepatic portal perfusion was subjectively scored between 1 (poor/none) and 5 (good/normal) based on the caliber of the intrahepatic PVs. A total of 264 CT scans were submitted from 29 institutions. Due to exclusion criteria, 33 (13%) were removed, leaving 231 CT scans to be included. Twenty-five different EHPSS anatomies were identified with five classifications accounting for 78% of all shunts (LGP [53%], LGC-post [11%], LCG [7%], LGC-pre [4%], and PC [4%]). Shunt origin involved the left gastric vein in 75% of the described classifications. Significant differences were identified among the five most common shunt types with respect to age at the time of CT scan (P = .002), breed (P < .001), and subjective portal perfusion score (P < .001). This refined anatomical classification system for feline EHPSS may enable improved understanding, treatment comparisons, and outcome prediction for cats with these anomalies., (© 2024 American College of Veterinary Radiology.)

- Abstract
A 6-year-old, female neutered Labrador retriever was presented with a chronic history of vomiting and anorexia. Abdominal ultrasound identified two large cavitated structures with echogenic content in the gastric fundus and pyloric region. CT revealed the intraparietal nature of these structures, one in the greater curvature and another one extending from the lesser curvature to the pyloric antrum. Surgical exploration revealed two areas of thickened gastric wall with intramural purulent material. Debridement and partial resection of the abscess (deroofing) were performed via a routine gastrotomy approach. Histopathology of a gastric wall sample revealed neutrophilic inflammation with intralesional vegetal foreign body. The presence of intralesional foreign body with a positive bacterial culture and macroscopic absence of peritonitis may suggest an intramural migrating vegetal foreign body. Gastric wall abscess should be included in a differential diagnosis in dogs with a history of chronic vomiting and the presence of gastric wall cavitated structures. Surgical debridement through a routine gastrotomy opening alleviated the clinical signs related to the intramural gastric abscesses in this dog with no recurrence at 22 months., (© 2024 The Authors.

- Abstract
Objective: To evaluate the feasibility of endoscopic inspection of thoracolumbar and lumbar pedicle tracts in a canine large-breed model and its accuracy for the detection of breached versus nonbreached tracts., Animals: 2 greyhound cadavers., Methods: CT scans of 2 greyhound cadavers from the sixth thoracic vertebra to the sacrum were obtained. Fifty-six pedicles were randomized to have drill tracts with different modified Zdichavsky grades (nonbreached, partial/full medial breach, or partial/full lateral breach) using 3-D-printed guides. Endoscopy was performed on a single occasion from October 9 to 10, 2023, using a 1.9-mm 0-degree needle arthroscope in a randomized blinded fashion. The grading of drill tracts was performed on postoperative CT. Specificity, sensitivity, positive and negative predictive values, and time to assign endoscopic grade were investigated., Results: Postoperative CT confirmed 43 nonbreached tracts, 7 medial breaches (partial/full), and 5 lateral breaches (partial/full). One tract was excluded because of guide misplacement. Intraosseous endoscopy was successfully performed in the remaining 55 drill tracts. Sensitivity to detect medial and lateral breaches was 71.4% and 60.0%. Negative predictive value was 93.1%. Specificity was 94.2%. Positive predictive value for detection of medial and lateral breaches was 83.3% and 54.5%. Median (range) time to assign an endoscopic grade was 118 (30 to 486) seconds., Clinical Relevance: Intraosseous endoscopy of pedicle drill tracts may be a useful adjunct technique during pedicle screw/pin placement in dogs.

- Abstract
Objective: To evaluate and report the quality of the scientific literature reporting complications associated with laparoscopic and laparoscopic-assisted procedures in client-owned or healthy research dogs and to report and illustrate laparoscopic complications related to individual organ systems., Study Design: Systematic review., Animals: Client-owned or healthy research dogs., Methods: A literature review was performed by using PubMed and CAB abstracts for English-language studies providing descriptions of complications related to laparoscopic and laparoscopic-assisted procedures in dogs. Study selection used PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guidelines. Quality assessment was performed by using a MINORS (Methodological Items for Non-Randomized Studies) scoring system and a grading scale of level of evidence. Descriptive statistics were used., Results: In total, 741 manuscripts were identified, with 64 manuscripts eligible for data extraction and quality assessment. The most represented organ system was the female genital tract, represented by 22 (34.4%) studies. The most commonly reported intraoperative and postoperative complications were related to abdominal entry and portal incisions, respectively. In 53 of 54 non-randomized studies, high risk of bias was found. Forty-eight (75%) studies provided level III or IV evidence., Conclusion: This report provides an updated review of complications related to laparoscopic and laparoscopic-assisted procedures in dogs, classified by organ system. The overall quality of evidence was low, limiting direct comparison of complication rates between studies., Clinical Significance: There is a need for implementation of standardized criteria for defining complications, study time frames and greater numbers of high quality prospective randomized trials in veterinary laparoscopy to permit comparison of complication and conversion rates between published studies and across organ systems., (© 2020 The American College of Veterinary Surgeons.)

- Abstract
Background: Thyroid neoplasia is a common endocrine neoplasm in dogs. The boxer is one of the reported breeds predisposed to malignant thyroid neoplasia. However, the association between thyroid neoplasia, malignancy and breed should be considered with caution., Cases Presentation: This article describes the presentation, clinical pathological findings, computed tomographic (CT) imaging findings and histopathological features of benign cystic thyroid tumour (cystadenoma) diagnosed in three boxers. These three dogs were presented for investigation of unilateral (n = 2) or bilateral (n = 1) cervical masses with no associated clinical signs of thyroid dysfunction. In each case, post-contrast CT scan identified a large, lateralised, non-invasive, well-defined homogeneous cystic structure with a hyperattenuating contrast-enhancing capsule of suspected thyroid origin displacing the surrounding cervical tissues. Ultrasound-guided fine needle aspiration of the cysts yielded fluid with a high thyroxine concentration in each case. Histopathology was consistent with thyroid cystadenoma in all cases. One dog was concurrently diagnosed with oral melanoma and euthanased. Two dogs underwent surgical excision with one lost to follow-up after 36 months and the other euthanased after 16 months following diagnosis of mast cell tumour., Conclusions: To the authors' knowledge, this is the first detailed report of non-functional benign thyroid cystadenoma in dogs and provides relevant information about case management for this type of tumour. The presence of a large cystic structure associated with benign non-functional thyroid neoplasia may be a condition to which boxer dogs are predisposed.

- Abstract
Objective: To determine current methods of arthroscopic skills training and proficiency assessment, identify skills considered fundamental to arthroscopy, and evaluate desire for a formal training and assessment program., Study Design: Anonymized electronic survey., Sample Population: Diplomates and residents of the American College of Veterinary Surgeons (ACVS) and European College of Veterinary Surgeons (ECVS)., Methods: An electronic survey was distributed in commercial software (Qualtrics, Provo, Utah). Questions were divided into 4 categories: (1) demographics, (2) arthroscopy experience, (3) teaching, and (4) proficiency assessment. Descriptive statistical analysis was performed. Comparisons between groups were performed by using χ
2 , t tests, and 1-way ANOVA (P ≤ .05)., Results: In total, 429 diplomates and 149 residents responded (response rate 28%). Overall, 80% of respondents trained using clinical cases. Barriers to simulator training included cadaver/simulator availability and time. Skills deemed most fundamental included anatomic knowledge, precise portal placement, triangulation, and image orientation. Overall, 90% of respondents supported a formal training program with requirement to demonstrate proficiency; 80% believed this should be part of standard ACVS/ECVS residency training., Conclusion: Arthroscopic skills are taught by using clinical cases, with subjective proficiency assessment. Fundamental skills are those that may be taught using simulators. There is enthusiasm for formal arthroscopic skills training and assessment., Clinical Significance: Improved acquisition and assessment of fundamental arthroscopic skills is indicated. A validated methodology for formal training using simulators, minimizing morbidity, and facilitating objective evaluation is warranted. This is the first phase of a project to develop and validate a simulator program., (© 2018 The American College of Veterinary Surgeons.)- Published
