Zawaly u psow i kotow - opis wybranych przypadkow

The aim of the study was the presentation of selected and recognized by autopsy and histopathology of cases with the development of internal organ infarction. The study was performed on 5 dogs and 1 cat, which died for different reasons and were autopsied in the Division of Pathological Anatomy, Department of Clinical Sciences of the Agricultural University of Warsaw from 2005 to 2006. In each particular case the clinical history was noted, additional laboratory findings were known in some cases. In each case autopsy and histopathological examination of the tissue samples was performed. Final diagnosis was established on the basis all diagnostic tests performed. The presence of the infarctions was recognized in 5 dogs and 1 cat: the animals were of different ages (4-12 years), of different breeds and both sexes. Lesions were localized in various internal organs, most often they were multiple (4 cases), and rarely were observed in one organ (2 cases); the spleen and lung were the most observed localization. In some cases infarctions were the direct or indirect cause of an animal’s death, in others they were incidental findings. It seems that the infarctions are rather rarely observed in companion animals, and their recognition is very difficult clinically. The pathomechanisms of infarction development are various but in most cases are associated with hypercoagulable states during the different pathologic processes.
