Clinical findings and diagnosis of thrombosis of the caudal vena cava in cattle


Braun, U (2008). Clinical findings and diagnosis of thrombosis of the caudal vena cava in cattle. Veterinary Journal, 175(1):118-125.

Abstract

This paper describes the causes, clinical findings and diagnosis of caudal vena caval thrombosis in cattle. Occlusion of the vein is caused by a ‘white’ thrombus, and typical clinical signs include chronic weight loss, poor general condition and intermittent fever. Most affected cattle have respiratory signs; in some, pulmonary haemorrhage, ascites and sudden death occur. Haematological analyses, endoscopy of the respiratory tract and ultrasonographic examination of the pleura, liver and abdomen should be carried out in cattle suspected of having thrombosis of the caudal vena cava. The most important diagnostic finding is dilatation of the caudal vena cava seen via ultrasonography. Normally, the caudal vena cava appears triangular in cross section but in cattle with thrombosis it is oval or circular. The prognosis is poor and there is no treatment.

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.
