Correlações morfo-radiográficas cardíacas em calopsitas (Nymphicus hollandicus, Kerr 1792)

Abstract

Birds of the Order Psittaciformes are often kept in captivity, in which there are several conditions that, without proper care, can generate a predisposition to diseases. Research has shown that captive parrots present a series of cardiovascular alterations with high frequency, but which are mostly diagnosed postmortem. Due to the difficulty in assessing the avian circulatory system, some lack of specificity of clinical signs and the presence of concomitant alterations, cardiovascular alterations, may be underdiagnosed in companion Birds, since the reported cases of ante mortem diagnosis are scarce. This Project aims to correlate morphological (macroscopic) cardiac parameters with radiographic parameters of cockatiels. Cardiac morphometric parameters data were analyzed from eight cockatiel Hearts, through external and internal measurements, then correlated with cardiac radiographic parameters through the RadiAnt DICOM Viewer 5.0.1 software program, being triplicated for each radiograph to increase accuracy. Robustness of the sample from right lateral and ventrodorsal exposures and furthermore, to complement these data, a histological analysis of the microscopic reference to the work was carried out. Data were statistically analyzed by paired sample tests to compare anatomical and radiographic dimensions, in addition to testing to compare anatomical measurements with each other. In view of the results presented in this article, the cockatiel heart has characteristics that converge with the heart of other birds, since the morphometric data obtained become relevant due to the lack of data in the literature regarding the cardiac anatomy of cockatiels
