Ultrasonography is an excellent method for investigation of animals with gastrointestinal disorders, and is particularly useful for excluding obstructive processes.
OBJECTIVE
To describe the effect of fasting on the technical success of abdominal ultrasonography specifically in respect of examination of the gall bladder, duodenum, pancreas, adrenal glands and portal vein in dogs.
METHODS
Randomised, prospective study of 150 dogs with a variety of physical characteristics. Animals were divided into two groups of 75 dogs each. Dogs in Group 1 were fasted for 8 to 12 hours before ultrasonographic evaluation and those in Group 2 were not but received food anytime between 10 minutes and 2 hours before the procedure.
RESULTS
Intraluminal gas can influence the visibility of organs, but intraluminal gas accumulation occurred independently of fasting status. The assessment of abdominal organs was not affected by whether or not an animal was fasted.
CLINICAL SIGNIFICANCE
Routine fasting of dogs before abdominal ultrasonography is not essential.
Nos últimos anos o furão (Mustela putorius furo) tornou-se um conhecido animal de estimação sendo observada uma população em constante crescimento no Brasil, e por conseqüência cada vez mais presente em clínicas veterinárias. O presente trabalho teve como objetivo avaliar a anatomia ultrassonográfica dos linfonodos abdominais de furões-europeus hígidos. Foram utilizados 20 animais, dentre os quais nove eram machos e onze fêmeas, com idade média total de três anos. Localizaram-se em 100% dos furões os linfonodos mesentéricos, em 55% dos animais os linfonodos pancreático-duodenal e esplênico, em 20% o linfonodo gástrico e em 5% o linfonodo hepático. Conclui-se que a localização e características ultrassonográfica dos linfonodos abdominais em furões são muito similares aos linfonodos abdominais de gatos, sendo este estudo uma orientação preliminar para a localização dos linfonodos abdominais de furões hígidos.
