Transcutaneous ultrasonographic characteristics of the canine cervical esophagus
Ultrasound is a readily available imaging modality that allows detailed visualization of the canine esophageal wall. However, in the literature, there are few reports of its use for this purpose. The aim of the present study was to document the sonographic appearance and measurements in normal dogs. Seven cadavers and ten healthy live dogs were examined using a 14MHz transducer. Two, four or six wall layers were identified using ultrasound. To the authors’ knowledge, the identification of six layers using ultrasound has not been reported before; this is apparently due to fibrous tissue located between the muscle layers as determined using histology. The mean ultrasonographic wall thickness for the live dogs was 2.8 mm ± 1 mm. These findings support the use of transcutaneous ultrasonography to evaluate the cervical esophagus, but further research is required to determine its use in clinical cases.
期刊介绍:
The Vlaams Diergeneeskundig Tijdschrift (ISSN 0303-9021) is a scientific journal that is published bimonthly (six issues per year). It presents mainly clinical topics and addresses itself to two very different readerships: the local Dutch speaking veterinarians in Belgium and the Netherlands, and the international veterinary and biomedical research community. Each issue contains scientific papers either in English, or in Dutch with an English abstract.
