Traumatic pericarditis in cattle: clinical, radiographic and ultrasonographic findings


Braun, U (2009). Traumatic pericarditis in cattle: clinical, radiographic and ultrasonographic findings. Veterinary Journal, 182(2):176-86.

Abstract

Pericarditis is an inflammation of the pericardium with accumulation of serous or fibrinous inflammatory products. In cattle, it is almost always attributable to a reticular foreign body that has penetrated the reticular wall, diaphragm and pericardial sac. The lead signs of pericarditis are tachycardia, muffled heart sounds, asynchronous abnormal heart sounds, distension of the jugular veins and submandibular, brisket and ventral abdominal oedema. The glutaraldehyde test is an important diagnostic tool because it is positive in >90% of affected cattle. Other common laboratory findings are leukocytosis and hyperfibrinogenaemia (indicating inflammation), and elevation of liver enzyme activity (reflecting hepatic congestion). Radiographs of the thorax and reticulum often show a foreign body cranial to the reticulum. In the majority of cases, massive fibrinopurulent adhesions obscure the cardiophrenic angle, cardiac silhouette and ventral diaphragm. Ultrasonography is the method of choice for diagnosis and characterisation of pericardial effusion. Echogenic deposits and strands of fibrin are seen on the epicardium, and the ventricles are compressed by the effusion. Severe pleural effusion is usually evident. In cattle with distension of the jugular veins and tachycardia, the differential diagnosis includes right-sided cardiac insufficiency attributable to other causes. Distension of the jugular veins without signs of right-sided cardiac insufficiency may occur with obstruction or compression of the cranial vena cava. The prognosis is poor, and pericardiocentesis or pericardiotomy are inadequate methods of treatment. Thus, prompt and humane euthanasia is indicated for cattle with traumatic reticuloperitonitis. Because a definitive diagnosis of traumatic reticuloperitonitis is not always possible based on clinical signs alone, radiography and ultrasonography of the thorax and reticulum are indicated in doubtful cases.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
