Use of computed tomography (CT) for the diagnosis of mechanical gastrointestinal obstruction in canines and felines.

The objective of this study was to describe the use of computed tomography (CT) for diagnosis of mechanical gastrointestinal (GIT) obstruction in canines and felines. Medical records of 130 canines and felines that underwent an abdominal CT scan between 2013 and 2015 at a specialty referral hospital for suspected gastrointestinal tract (GIT) obstruction were reviewed. Images were evaluated by a single board-certified radiologist for the presence of foreign material, evidence of obstruction, and location of foreign material present.

Proximal tibial metaphyseal fractures in immature dogs.

Objective: To describe proximal tibial metaphyseal fractures in immature dogs.

Materials And Methods: Medical records of immature dogs with metaphyseal fractures of the proximal tibia were reviewed and data were collected on signalment and history of trauma. Craniocaudal and mediolateral radiographs were evaluated for the determination of the bones fractured, location of the fracture within the bone, fracture configuration, and the presence of fracture segment displacement and angulation.

Total laparoscopic gastropexy using 1 simple continuous barbed suture line in 63 dogs.

Objective: To describe the use and outcome of a single, simple continuous, barbed suture line for prophylactic, total laparoscopic gastropexy in dogs.

Study Design: Multi-center, retrospective case series.

Animals: Sixty-three client-owned dogs.

Articular cartilage lesions of the patellofemoral joint in dogs with naturally occurring cranial cruciate ligament disease.

Objective: To evaluate frequency, severity, and location of patellofemoral (PF) osteoarthritis (OA) in dogs with naturally occurring cranial cruciate ligament (CCL) disease.

Study Design: Cross-sectional observational study.

Animals: Dogs (n = 40; stifles, 44).

Sensitivity, positive predictive value, and interobserver variability of computed tomography in the diagnosis of bullae associated with spontaneous pneumothorax in dogs: 19 cases (2003-2012).

Objective: To determine the sensitivity, positive predictive value, and interobserver variability of CT in the detection of bullae associated with spontaneous pneumothorax in dogs.

Design: Retrospective case series.

Animals: 19 dogs with spontaneous pneumothorax caused by rupture of bullae.

Comparison between bolus tracking and timing-bolus techniques for renal computed tomographic angiography in normal cats.

Renal dual-phase computed tomograpic angiography (CTA) is used to assess suitability of feline donors prior to transplantation. A prerequisite for successful CTA is optimal synchronization between the arterial passage of contrast material and CT data acquisition. This retrospective study was conducted to compare quality of renal vascular enhancement at dual-phase CTA in normal cats between two techniques of timing of data acquisition: the timing-bolus and the bolus tracking method.

Use of a self-expanding metallic stent to palliate esophageal neoplastic obstruction in a dog.

Case Description: An 11-year-old spayed female Collie was evaluated because of regurgitation, dysphagia, severe ptyalism, coughing, and weight loss of approximately 12 weeks' duration. Esophageal squamous cell carcinoma had been diagnosed prior to referral on the basis of results of radiographic and endoscopic examination and histologic evaluation of biopsy samples. A percutaneous endoscopically placed gastrostomy (PEG) tube had been inserted 2 weeks prior to referral, and the dog was being treated for infection at the gastrostomy site.

Characterization of normal feline renal vascular anatomy with dual-phase CT angiography.

Helical computed tomography angiography was used to evaluate the renal vascular anatomy of potential feline renal donors. One hundred and fourteen computed tomography angiograms were reviewed. The vessels were characterized as single without bifurcation, single with bifurcation, double, or triple.

Dual-phase computed tomographic angiography in three dogs with pancreatic insulinoma.

This article describes the findings in three dogs with histopathologically confirmed pancreatic insulinoma using dual-phase computed tomographic angiography (CTA). In all three dogs, dual-phase CTA findings identified lesions not seen on ultrasonography, including the actual identification of the primary pancreatic neoplasm in two dogs. CTA findings were in agreement with the surgical and histopathological findings.

Helical computed tomographic angiography of the normal canine pancreas.

Helical abdominal computed tomography (CT) was performed in nine normal beagle-mix dogs. Following cephalic vein injection of ionic iodinated contrast medium via power injector (rate 5 ml/s) dual-phase CT was performed in all dogs. A delayed scan was performed in five dogs between 5 and 13 min after the contrast medium injection.
