Aneurisma e ruptura da aorta em ruminantes no Semiárido da Paraíba.

Abstract

A total of 1,831 autopsied ruminants, cattle were 709 (38.7%), 583 sheep (31.9%) and 539 goats (29.4%). Of these, four were diagnosed with rupture in the aorta due to aneurysm, corresponding to 0.23% of autopsies. In goats, the prevalence was 0.37%, corresponding to two cases. Sheep occurred in only one case, with a prevalence of 0.17%. 0.14% in cattle, only one case occurred in this species. In the first goat no clinical evolution, since the second goat had clinical signs of caseous lymphadenitis was observed. The sheep was found dead by the owner and no clinical manifestation was observed. In the case of beef, abdominal distension, was the reason the animal was taken to the Veterinary Hospital, and stress during transport is probably what led to rupture of the aneurysm. In all cases there was a sudden death of the animals. The main symptom was found in animals staining white porcelain mucous. The main macroscopic findings at necropsy were hemoperitoneum or hemothorax, and rupture of the aorta artery. Although it occurs sporadically, the rupture of the aorta due to aneurysm, causes great economic losses to the owners, as always results in death of the animal.
