Ultrasonographic assessment of the normal ileocecocolic junction in dogs.

The ultrasonographic appearance of the ileocecocolic junction (ICCJ), comprising the ileocolic junction (ICJ) and the cecocolic junction (CCJ), has not been established in dogs. The purpose of this prospective study was (1) to evaluate the feasibility and technique of systematic ultrasonographic evaluation of the ICJ and CCJ and (2) to describe its ultrasonographic features. Abdominal ultrasound was performed in 102 fasted dogs, free of digestive signs.

Computed tomographic features of gastric and esophageal content in dogs undergoing CT myelography and factors influencing the presence of esophageal fluid.

Background: Gastroesophageal reflux (GER) has been reported to be a common finding in dogs under general anesthesia.

Objectives: The aim of this retrospective study was to assess the esophageal and gastric contents in a population of dogs undergoing computed tomographic myelography (myelo-CT) examination and to evaluate the factors influencing the presence of esophageal fluid (gastric content, duration of anesthesia, body position, and intrinsic factors).

Methods: Esophageal and gastric contents of 83 non-brachycephalic dogs were retrospectively assessed based on plain and myelo-CT scans.

Lung lobe torsion in 15 dogs: Peripheral band sign on ultrasound.

The diagnosis of lung lobe torsion in dogs is usually based on radiological, endoscopic, and CT features. Few ultrasonographic descriptions have been published. The purpose of this multicenter, retrospective, and prospective observational study was to investigate the presence of a hypoechoic area forming a pulmonary band or line at the periphery of the twisted lobe on ultrasonography and assess its significance by comparing it to CT and histological findings.

Ultrasonographic characteristics of the abdominal esophagus and cardia in dogs.

Differential diagnoses for regurgitation and vomiting in dogs include diseases of the gastroesophageal junction. The purpose of this cross-sectional study was to describe ultrasonographic characteristics of the abdominal esophagus and gastric cardia in normal dogs and dogs with clinical disease involving this region. A total of 126 dogs with no clinical signs of gastrointestinal disease and six dogs with clinical diseases involving the gastroesophageal junction were included.

Ultrasonographic characterization of the feline cardia and pylorus in 34 healthy cats and three abnormal cats.

A prospective study was performed in 34 fasted healthy cats to describe the normal ultrasonographic anatomy of the cardia and pylorus. Measurements were obtained for the caudal esophageal wall thickness (Ew), cardia wall thickness (Cw), pyloric wall thickness (Pw), thickness of the pyloric muscularis (Mp), length of the thicker part of the proximal duodenal submucosa (Dl). Among the 34 cats, 24 were examined using a linear transducer, and 10 with a microconvex transducer.

Persistent truncus arteriosus in a cat.

A 5-month-old male domestic cat presented with a history of rapid, heavy breathing and cyanosis after exercise. Physical examination showed an abnormal respiratory pattern with an increased rate and stress-induced cyanosis. Auscultation revealed tachycardia and a grade 5/6 systolic murmur best heard over the left base.

Anatomical study of cranial nerve emergence and skull foramina in the dog using magnetic resonance imaging and computed tomography.

Twenty-two magnetic resonance imaging (MRI) brain studies of different breeds of dogs were reviewed to assess the anatomy of cranial nerve (CN) origins and associated skull foramina. These included five anatomic studies of normal brains using 2-mm-thick slices and 17 studies using conventional clinical protocols with 3- or 4-mm slices on both normal and abnormal brains. Images were obtained in transverse, sagittal, and dorsal planes to allow a thorough comparison between studies.
