Abstract:
The current study was conducted for radiographic evaluation of caudal vena cava and aortic sizes of eight apparently healthy German shepherd dogs free from cardiothoracic disorders and three dogs that had cardiac problems. The course of caudal vena cava passing through abdomen into right atrium makes it visible on lateral radiograph. Thus on a lateral radiograph, the CVC to descending aorta ratio, fourth thoracic vertebra length, and fourth rib width are helpful predictors of right heart illness. To examine the caudal vena cava (CVC) and aortic (Ao) parameters, the animals were subdivided into two groups; group-I containing healthy animals and group-II contained animals with cardiac abnormalities). Mean±S.E values of body weight and age were measured 26.80±1.26 (range 22-33.2) kg and 55.00±3.62 (range 36-72) months and 36±1.53 (range 34-39) kg and 68±4.00 (range 60-72) months in animals of the group-I and II, respectively. The majority of the parameters between group I and group II animals were found to be non-significant. The goal of this study was to establish standard values (ranges) for CVC and aortic parameters.
