Ultraschallbefunde bei einem Rind mit Aszites infolge Thrombose der Vena cava caudalis


Schweizer, G; Wehbrink, D; Müller, R; Hilbe, Monika; Braun, Ueli (2005). Ultraschallbefunde bei einem Rind mit Aszites infolge Thrombose der Vena cava caudalis. Tierärztliche Praxis. Ausgabe G, Grosstiere/Nutztiere, 33(06):389-394.

Abstract

Objective: Description of a heifer with ascites due to thrombosis of the caudal vena cava. Material and methods: Case report of a 21-month-old Swiss Braunvieh heifer. Results: The most important clinical findings included a dilated pearshaped abdomen, positive swinging and percussion auscultation of the abdomen and a small rumen, which was compressed by the intraabdominal fluid. Laboratory investigation revealed a lowered haematocrit, elevated liver enzyme activities and a mild leukocytosis. Ultrasonographic examination of the abdomen showed a massive accumulation of anechoic fluid in which the abdominal organs appeared to be floating. Instead of its normal triangular shape, the caudal vena cava had a circular cross-section near the liver, which indicated dilatation of the vein due to obstruction or compression. Fluid collected by abdominocentesis was determined to be a transudate. Based on these findings, a diagnosis of ascites due to thrombosis of the caudal vena cava was made. The cause was thought to be rupture of a liver abscess into the caudal vena cava. Because of a poor prognosis, the heifer was slaughtered. Postmortem examination revealed multiple liver abscesses, which had a maximal diameter of 5 cm and contained yellow creamy material. An abscess immediately adjacent to the caudal vena cava had ruptured into the vein. At the point of rupture into the vein, there was a septic thrombus, which partially occluded the lumen of the caudal vena cava. Conclusion: In cattle with dilatation of the abdomen and positive swinging auscultation an ascites should also be taken into consideration. Exact knowledge of the causes is essential for further examination. Clinical relevance: Correct diagnosis in cattle with dilatation of the abdomen is of great importance for prognosis and eventual treatment.
