Achados de necropsia de cães com peritonite primária

Abstract

ABSTRACT The peritonitis definition is an inflammatory process of the peritoneal cavity, of variable etiology, with the potential to evolve into sepsis. Among the forms of peritonitis, primary peritonitis is the rarest, occurring through the dissemination of an infectious focus via the hematogenous or lymphatic route without any damage to the abdominal cavity. To describe the necropsy findings observed in two dogs with primary peritonitis, and to discuss sepsis as the cause of death. Necropsies were performed on two pitbull dogs, aged between 1 and 2 months. Among the main necropsy findings, the most prominent was the presence of marked acute diffuse fibrinopurulent peritonitis. Ear lesions compatible with bilateral conchectomy were also found in both dogs. The entry point of the peritonitis agent may have been the conchectomy lesion or bacterial translocation of parvovirus. No other alterations that could indicate sepsis were evidenced. However, the absence of a complete history, macroscopic sepsis lesions (not always identified at necropsy), histology, and identification of the causative agent, leads to the belief that the animals died as a result of a septic condition secondary to peritonitis, aggravated by multiple organ dysfunction. The authors of the current human consensus on sepsis emphasize that sepsis-induced organ dysfunction can be subtle or even imperceptible, and should therefore be considered in every patient presenting with an infectious process.
