“…Além desses sinais, outros podem ser observados, como a esplenomegalia que é resultante de um fluxo arterial contínuo seguido de uma obstrução venosa que determina o aumento do órgão (Maxie et al, 1970). As manifestações clínicas encontradas na cadela aqui relatadas corroboram com os achados de outros autores (Maxie et al, 1970, Konde et al, 1989, Neath et al, 1997, Mai, 2006, Rial et al, 2010, Azevedo et al, 2011, Ortiz et al, 2016.…”

“…O paciente apresentava anemia, assim como relatado por outros autores (Maxie et al, 1970, Konde et al, 1989, Neath et al, 1997, Mai, 2006, Rial et al, 2010, Azevedo et al, 2011, Ortiz et al, 2016. A anemia é resultante do sequestro de hemácias pelo baço torcido e da inflamação em curso, desde que descartadas hemoparasitose e anemia hemolítica imunomediada, segundo Schnier (2010).…”

“…As manifestações clínicas são inespecíficas, podendo ocorrer sinais de dor abdominal, aumento do pulso e da frequência respiratória, palidez das mucosas, vômito, anorexia, perda de peso, distenção abdominal, depressão e letargia (Konde et al, 1989, Neath et al, 1997, Azevedo et al, 2011, Ortiz et al, 2016. Exames complementares como radiografia e ultrassonografia devem ser utilizados; porém a laparotomia exploratória é a única forma de diagnóstico definitivo para a torção esplênica isolada (Konde et al, 1989, Goldsmid et al, 1994.…”

RESUMO.Torção esplênica é uma condição rara em cães. A rotação ocorre em seu pedículo vascular e geralmente ocorre concomitantemente à dilatação vólvulo gástrica, porém a torção primária esplênica é rara. Segundo a literatura essa enfermidade acomete normalmente cães de grande porte e raças de peito profundo. Os sinais clínicos, achados laboratoriais e radiográficos são inespecíficos e inconclusivos para o diagnóstico preciso de torção esplênica. Assim, a ultrassonografia juntamente com o uso do Doppler colorido tem sido relatada como ferramentas fundamentais para a sugestão do diagnóstico de torção esplênica, que é confirmado através de laparotomia exploratória, geralmente seguida de esplenectomia total como forma de tratamento. Este estudo relata o caso de um cão da raça Pit Bull, três anos de idade, cujo exame ultrassonográfico foi uma ferramenta de grande valor diagnóstico para detecção desta enfermidade.Palavras chave: Baço, torção esplênica, ultrassonografia esplênica Primary splenic torsion in dogs: Case report ABSTRACT. Splenic torsion is a rare condition in dogs. The torsion occurs in the vascular pedicle and usually occurs concomitantly with dilatation gastric volvulus, but the primary splenic torsion is rare. According to the literature, this disease usually affects dogs of big size and breeds of deep chest. Clinical signs, laboratory and radiographic findings are nonspecific and inconclusive for the accurate diagnosis of splenic torsion. Thus, ultrasound along with the use of color Doppler has been reported as fundamental tools for the suggestion of the diagnosis of splenic torsion, which is confirmed by exploratory laparotomy, usually followed by total splenectomy as a form of treatment. This study reports the case of a 3-year-old Pit Bull dog whose ultrasound examination was a tool of great diagnostic value for the detection of this disease.

The determination of arterial vascular distribution patterns can contribute to more detailed knowledge on arterial systems. In this context, the aim of the present study was to describe the collateral aortic branches in the collared peccary, aiming to define a standard model for this species, providing information through comparative anatomy for analysis of some evolutionary aspects of the order Artiodactyla. Ten young male animals were employed. The vascular system was washed with a saline solution and then perfused with Neoprene 450 latex coloured with red or yellow pigment, followed by collateral aorta branch dissections and analyses. The contrasted digital radiography technique was applied to two animals, which were initially perfused with a barium sulphate solution (1 g/ml) and Neoprene 450 latex at a 1:3 ratio, and subsequently, the digital radiographic examination was performed. The aortic arch of the collared peccary emitted the brachiocephalic trunk and the left subclavian artery, while eight symmetric pairs of dorsal intercostal arteries originated from the thoracic aorta. The abdominal aorta, in turn, exhibited the celiac, cranial mesenteric, renal, caudal mesenteric, testicular, external iliac, internal iliac and sacral arteries as the collateral branches in all studied animals. Therefore, no relevant variations were observed regarding the arrangement of the arterial distribution of the aorta, thus suggesting a static standard model in the collared peccary.

Ingestion of metallic and/or sharp foreign bodies triggers cases of traumatic reticuloperitonitis and its sequelae in cattle. Among these sequelae, we can highlight traumatic reticulosplenitis, that has high mortality, although its frequency in the ruminant medicine is low. Therefore, based on the scarcity of information on this disease, the current study aimed to evaluate the clinical, laboratory, ultrasonographic, and pathological findings of 30 adult cattle diagnosed with traumatic reticulosplenitis. Clinical, ultrasound, and anatomopathological findings were analyzed using descriptive statistics and laboratory data were evaluated using measures of central tendency. Clinically the animals presented dehydration and alterations in behavior, appetite, and ruminal motility. Hematological findings revealed neutrophilic leukocytosis (37077.17±25004.59cell/μL) with regenerative left shift and hyperfibrinogenemia (1130±364.98mg/dL). The ultrasound examination enabled visualization of mobile and echogenic filaments that corresponded to the presence of fibrin adhesions. Displacement of the reticulum and irregularity in its contour, as well as alterations in the quantity, pattern, and amplitude of reticular contractions were also observed. Splenic alterations such as abscesses were found, characterized as circular structures of varying sizes delimited by capsules containing variable echogenicity. Splenic vein thrombosis and spleen folding were also observed. The results obtained in the current study indicated that traumatic reticulosplenitis causes nonspecific clinical signs, severe laboratory alterations and, mainly, that ultrasound is an efficient method for the diagnosis of this disease, since the anatomopathological lesions confirmed the ultrasound findings.
