The objective of this retrospective study was to describe the clinical presentation and ultrasonographic findings in water buffaloes suffering from congestive heart failure. Fifty-three buffaloes with congestive heart failure, which was confirmed postmortem, were included. The final diagnoses were traumatic pericarditis (n = 38) and vegetative endocarditis (n = 15). Ten healthy buffaloes were enrolled in this study as controls. The main clinical presentations were those related to right-sided congestive heart failure including peripheral edema, venous distension and jugular pulsation, and a sharp drop in milk yield. Only 5 buffaloes exhibited signs of left-sided heart failure. Ultrasonographic examinations showed cardiac and extracardiac lesions. Accumulation of massive anechoic fluids in the pericardial sacs, peritoneum, and pleura represented pericardial, peritoneal, and pleural effusions, respectively. In buffaloes with endocarditis, the affected valves appeared as hyperechogenic thick mass structures with nodular or proliferative vegetative lesions. Small (<25 mm) and large (>25 mm) vegetative lesions were imaged. The most affected valve was the tricuspid (n = 8), then the mitral (n = 5) and pulmonary (n = 2). In addition, perireticular abscesses, hepatomegaly, dilated caudal vena cava, and lung consolidations were also imaged. In conclusion, the prognosis seemed poor. Ultrasonography may be helpful in the evaluation of lesions in buffaloes with congestive heart failure.

“…Ultrasonography allows some assessment to be made of small intestinal activity and lumen contents. In contrast to the small intestine, which has vigorous peristaltic activity and segmental contractions, few contractions are observed in the large intestine (Braun 2009). However, true peristaltic activity has not been easily or widely determined, because differentiating peristaltic activity from oscillatory activity using B-mode ultrasonography has not been possible (Mitchell et al 2005).…”

ABSTRACT:The aim of this study was to assess the usefulness of ultrasonographic examination of the large intestine in 10 clinically healthy Jersey/Red Sindhi crossbred cows. The area extending from the tuber coxae to the 6 th intercostal space (ICS) and from the lumbar transverse processes to the linea alba on the right side was shaved. An imaginary line was drawn from the distal third of the femur up to the 8 th ICS parallel to the longitudinal axis of the cow. The large intestine was scanned dorsal to this imaginary line. Only the near wall of the large intestine adjacent to the abdominal wall could be imaged ultrasonographically. Based on the topographical anatomy, the ultrasonographic images of the caecum and the proximal loop of the ascending colon (PLAC), resembling the 'arc of a circle' , were observed in the mid to dorsal right paralumbar fossa and the 12 th ICS; however, the caecum and the PLAC could not be differentiated with certainty using ultrasonography. Similarly, the ultrasonographic images of the spiral loop of the ascending colon (SLAC), resembling a 'cycloid' , could be imaged through the 12 th to 11 th ICSs and in the dorsal right paralumbar fossa; yet, ultrasonographically, it was difficult to differentiate the SLAC from the descending loop of the ascending colon, transverse colon, and descending colon, respectively. The differences (qualitative and quantitative) in the degrees of curvatures of various ultrasonographic images of parts of the large intestine were also not helpful. In conclusion, ultrasonographic imaging of various parts of the bovine large intestine should be interpreted with caution.Keywords: ultrasonography; large intestine; caecum; colon; cows List of abreviations DC = descending colon, DLAC = descending loop of the ascending colon, ICS = intercostal space, PLAC = proximal loop of the ascending colon, SC = sigmoid colon, SLAC = spiral loop of the ascending colon, TC = transverse colon Knowledge of the topographic relations of the large intestine (caecum and colon) to the body wall is essential to the veterinary surgeon for its clinical examination, which includes the techniques of transrectal palpation, laparoscopy, ultrasonography, and diagnostic laparotomy. The caecum lies in the dorsal part of the right abdominal cavity and extends from the middle of the lumbar region to the pelvic inlet with a free, rounded blind apex which projects caudally from the supraomental recess. The colon consists of the ascending colon, transverse colon, and descending colon. The ascending colon, the longest part of the large intestine, has three parts/loops (proximal, spiral, and distal). The proximal loop of the ascending colon (PLAC) runs cranially for a short distance to the plane of the right kidney, where it doubles back dorsal to the first part and the caecum. It then turns mediodorsally around the caudal border of the mesentery and runs cranially on the left side of the mesentery. Ventral to the descending duodenum, in the supraomental recess of the greater omentum, are the PLAC and t...

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.
