“…The reticulum was visualised ultrasonographically in all cows confirming previous findings (Braun and Götz, 1994;Braun and Rauch, 2008). It had a crescent shape, was immediately adjacent to the peritoneum and had 11.0 ± 2.12 biphasic contractions in 9 minutes (1.2 ± 0.24 contractions/min) (Tab.…”

“…They were also invasive because they involved fistulation of the rumen. Ultrasonography has been used successfully for the assessment of the reticulum and reticular motility (Braun and Götz, 1994;Braun and Rauch, 2008) as well as for imaging the rumen (Tschuor and Clauss, 2008;Imran et al, 2011;Braun et al, 2013). The main goal of this study was therefore to investigate the feasibility of ultrasonography for the assessment of ruminal motility.…”

The goal of this study was to investigate the feasibility of ultrasonographic assessment of reticuloruminal motility in 45 healthy cows. The transducers of five ultrasound machines were connected to a digital video recorder and placed simultaneously at five sites on the left side of the cows to scan the reticulorumen (reticulum; ruminal atrium; dorsal sac of the rumen; left longitudinal groove; ruminal recess, caudodorsal and caudoventral blind sacs). The video streams from all five ultrasound machines were recorded synchronously with the same time line and displayed on a single monitor. Time 0 was defined as the start of a biphasic reticular contraction. The reticulum was visualised in all cows and had 11.0 ± 2.12 biphasic contractions in 9 min. The ruminal atrium was visualised in 40 (89%) cows and had 10.7 ± 2.10 contractions in 9 min, which started at the time point 5.0 ± 0.83 sec and lasted 7.0 ± 2.14 sec. Contractions of the dorsal sac of the rumen, visible in all cows, were visualised in 29 (64%) cows. There were 9.5 ± 1.8 contractions in 9 min that started at the time point 4.0 ± 0.85 sec and lasted 8.2 ± 1.04 sec. The left longitudinal groove was seen contracting in 39 (87%) cows. There were 10.2 ± 1.98 contractions in 9 min that started at the time point 4.1 ± 1.81 sec and lasted 7.8 ± 1.19 sec. Contractions of the ventral sac of the rumen (ruminal recess) were seen in 31 (69%) cows. There were 7.5 ± 2.59 contractions in 9 min that started at the time point 14.3 ± 4.30 sec. Contractions of the caudodorsal and caudoventral blind sacs were seen in 34 (76%) cows. There were 9.0 ± 2.75 (1.0 ± 0.31) contractions/min and 9.4 ± 2.09 (1.0 ± 0.23) contractions/min of the dorsal and ventral blind sacs, and they started at the time points 6.2 ± 1.32 sec and 21.3 ± 6.20 sec, respectively. Primary contraction cycles were seen in all cows and secondary cycles in 22 (49%) cows. The former were complete in 37 (82%) cows and incomplete in 8 (18%). There were 11.0 ± 2.12 primary and 4.5 ± 2.15 secondary cycles in 9 min, and the ratio between primary and motilisecondary cycles averaged 2.4:1. Ultrasonography is suitable for the assessment of reticuloruminal motility in cattle. cows. There were 10.2 ± 1.98 contractions in 9 min that started at the time point 4.1 ± 1.81 sec and lasted 7.8 ± 1.19 sec.

“…Además, las paredes de los vasos hepáticos se observan hiperecoicas, siendo sugestivo de un cuadro de lipidosis hepática (Braun 2009b;Imran et al 2011). Se observa, también, marcada peritonitis a nivel de la pared del retículo y del rumen (Braun et al 1993;Braun et al 2013), con la formación de un espacio de 3,5 cm de distancia entre pared abdominal y pared de los órganos internos; en este espacio se observa distintos grados de ecogenicidad a lo largo de la evaluación de las paredes, sugiriendo alto contenido de exudados y transudados. Se determinó, además, gran cantidad de material fibrinopurulento diseminado en la cavidad (Figura 2).…”

“…Se determinó, además, gran cantidad de material fibrinopurulento diseminado en la cavidad (Figura 2). A nivel de flanco izquierdo, en el rumen, se observa engrosamiento e hiperecogenicidad de la pared, confirmando un proceso diseminado de peritonitis (Braun et al 2013). Alrededor de 4 centímetros de material con ecogenicidad aumentada es observado entre pared abdominal y rumen, revelando peritonitis séptica (Braun et al 1993;Braun 2009a …”

Resumen: La reticulopericarditis traumática es una enfermedad que puede afectar, severamente, a los bovinos, al producir efectos importantes como reducción en su rendimiento general y descarte temprano. La ingestión de cuerpos extraños punzocortantes, causantes de una reticuloperitonitis, en primera instancia, es el factor primario, mientras que las contracciones ruminales y la presión del útero grávido son factores favorecedores. Se describe, en este trabajo, los aspectos clínicos y hallazgos post mortem de un caso de reticulopericarditis, de un Bos indicus, macho, de ocho años. Se hace especial énfasis en el abordaje clínico y los hallazgos ultrasonográficos a nivel de cavidad abdominal y cavidad torácica. Mediante el diagnóstico clínico y el apoyo de las imágenes, se evidenció una pericarditis séptica. Dada la condición del animal, se procedió al sacrifico. Se reporta, entonces, las alteraciones orgánicas macroscópicas y microscópicas producidas por la enfermedad.Palabras claves: bovinos, cebú, trópico, ultrasonido, patología, sistema digestivo, sistema cardiovascular.Abstract: Traumatic reticuloperitonitis is a disease that can severely affect cattle by producing important chronic effects leading to decreased productive performance and early culling. The ingestion of sharp objects, which can cause reticuloperitonitis as a primary cause, is the primary factor. Conditions such as ruminal contractions and the pressure of the gravid uterus may favor the disease. This paper describes clinical aspects and post-mortem findings of a case of reticuloperitonitis in an eight-year old Bos indicus male. Special emphasis is made on the clinical approach and the ultrasound findings of the abdominal and thoracic cavities. As a result of the clinical diagnosis supported with ultrasound images, a septic pericarditis was evidenced. Given its condition, the animal was sacrificed. Consequently, macroscopic and microscopic organic alterations caused by the disease are reported in the paper.
