Objective: To describe the presentation, diagnostic findings, surgical treatment via video-assisted thoracic surgery (VATS), and short-term outcomes of two dogs with caudal mediastinal paraesophageal abscesses (CMPA).

Animals: Two client-owned dogs.

Study Design: Retrospective case series.

Nontraumatic Pneumorrhachis and Intraforaminal Gas, Presumed Intravascular, Is Occasionally Detected in Dogs Undergoing Computed Tomography Angiography Without Immediate Complications.

Pneumorrhachis is a rare condition in human and veterinary medicine, defined as gas within the vertebral canal. Iatrogenic causes are the most common source of nontraumatic PR reported in humans. PR has been recognized in dogs undergoing routine CT.

A Pilot Study on Using an Artificial Intelligence Algorithm to Identify Urolith Composition through Abdominal Radiographs in the Dog.

In small animal practice, patients often present with urinary lithiasis, and prediction of urolith composition is essential to determine the appropriate treatment. Through abdominal radiographs, the composition of mineral radiopaque uroliths can be determined by considering many different factors; this can be complex and, as such, tailor-made for the use of artificial intelligence (AI). The Minnesota Urolith Center partnered with Hill's Pet Nutrition to develop a deep learning AI algorithm (CALCurad) within a smartphone application called the MN Urolith Application that allows for the preliminary assessment of urolith composition.

Laparoscopic ultrasound-guided microwave ablation of hepatocellular carcinoma in a dog.

Objective: The aim of the study was to describe laparoscopic ultrasound (LUS) to guide microwave ablation (MWA) of hepatocellular carcinoma (HCC) in a dog.

Animals: A 13-year-old female spayed Husky.

Study Design: Case report.

Comparative morphology in the context of facial reduction: Modularity in primate, dog, and bat crania.

Biological variation in the mammalian skull is the product of a series of factors including changes in gene expression, developmental timing, and environmental pressures. When considering the diversity of extant mammalian crania, it is important to understand these mechanisms that contribute to cranial growth and in turn, how differences in cranial morphology have been attained. Various researchers, including Dr.

Cystine and urate cystoliths in dogs are frequently visible on radiographs prior to surgical or nonsurgical removal.

Objective: To investigate the frequency at which cystine and urate cystoliths (stones) are visible on radiographs prior to surgical or nonsurgical retrieval.

Methods: Records of client-owned dogs (n = 331) were analyzed between January 2019 and December 2023 for cystoliths submitted for stone analysis after surgical removal or nonsurgical retrieval. Records were analyzed for cystolith type; when cystine or urate stones were identified, records were analyzed for signalment, procedure, presence of mineral opaque cystoliths on pre-procedural radiographs, urine pH and crystalluria, history of previous cystoliths, prior prescription diet attempt, recurrence, and genetic, congenital and acquired comorbidities.

Cooled feline intestine and fresh intestine did not differ in enterotomy leak pressure testing or in gross wall thickness measurement.

Objective: To report gross anatomical gastrointestinal measurements and compare enterotomy leak pressures between fresh and cooled feline cadavers.

Study Design: Ex vivo, randomized study.

Animals: Fresh feline cadavers (n = 20).

Hepatic insufficiency in two juvenile dogs with histoplasmosis.

A 9-month-old female intact toy poodle and a 1-year-old female intact Labrador retriever mix presented to separate teaching hospitals for chronic histories of malaise and clinicopathologic evidence of hepatic dysfunction. The signalment and clinical histories of these dogs prompted consideration of a congenital portosystemic shunt as a primary differential. However, microscopic evaluation of peritoneal effusion, pleural effusion, and peripheral blood samples from the dogs revealed round to ovoid yeast organisms morphologically most compatible with Histoplasma capsulatum.

Laparoscopic ultrasonography of the liver is feasible and safe in dogs.

Objective: To describe the feasibility and technique for performing laparoscopic ultrasound (LUS) of the liver in dogs.

Animals: 12 client-owned dogs presenting for elective laparoscopic surgery from January 1, 2022, to October 31, 2022.

Methods: Laparoscopic exploration and LUS of the liver were performed in all dogs.

A Novel Standardized Method for Aiding to Determine Left Atrial Enlargement on Lateral Thoracic Radiographs in Dogs.

Background: Left atrial enlargement indicates severe cardiac disease. Although the gold standard for determining left atrial size is echocardiography, many veterinary practices lack the necessary equipment and expertise. Therefore, thoracic radiography is often used to differentiate cardiogenic pulmonary edema from primary respiratory diseases and to facilitate distinguishing dogs with stage B1 and B2 mitral valve degeneration.

Radiographic and ultrasonographic appearance of a jejunal torsion-volvulus in a dog.

A 1.5-year-old male neutered, 5 kg, Dachshund was referred for anorexia and vomiting for several days' duration. Radiographs revealed concern for a small intestinal obstruction.

Computed tomographic features of double aortic arch in six dogs.

Double aortic arch (DAA) is a rare, congenital anomaly in small animals, resulting in a complete vascular ring encircling the esophagus and trachea, and subsequent compression of these organs. Few studies have reported utilizing CT angiography (CTA) for diagnosing DAA in dogs; thus, the imaging features are currently lacking in the literature. The objectives of this retrospective, multicenter, descriptive case series were to report the clinical and CTA characteristics of DAA in surgically treated cases.

Percutaneous transvenous coil embolization of an extrahepatic portosystemic shunt in a cat.

Case Summary: A 10-month-old male domestic shorthair cat presented for surgical treatment of a congenital portosystemic shunt. The cat had a history of lethargy and ptyalism. Pre- and postprandial bile acids were markedly elevated.

Percutaneous transvenous coil embolization of congenital intrahepatic portosystemic shunts in small- and toy-breed dogs: 20 cases (2015-2021).

Objective: To describe outcomes of small- and toy-breed dogs with a congenital intrahepatic portosystemic shunt (IHPSS) treated with percutaneous transvenous coil embolization (PTCE).

Animals: 20 small- and toy-breed dogs with an IHPSS.

Procedures: All dogs underwent CT angiography for shunt evaluation as well as PTCE.

Prospective evaluation of lymphatic embolization as part of the treatment in dogs with presumptive idiopathic chylothorax.

Objective: To describe the embolization technique and short-term clinical outcome in dogs undergoing lymphatic embolization (LE) as part of treatment for presumptive idiopathic chylothorax (IC). Additionally, to document findings in computed tomography lymphangiography (CTLa) following embolization.

Study Design: Prospective case series.
