Objective:
To present details of an unusual case of caudal vena caval obstruction and its management in a cat.
Study Design:
Clinical case report.
Study Population:
A 15 month old male castrated domestic shorthaired cat.
Results:
The diagnostic evaluation included the use of digital subtraction angiography and ultrasonography to locate the caudal vena caval obstruction. Treatment initially involved puncture and balloon dilation of the obstructed area of the cava. After reobstruction, the stenotic area was redilated and stented. The cat was euthanatized 4 weeks later because of vomiting, anorexia, and abnormal behavior, presumed to be associated with liver disease.
Conclusion And Clinical Relevance:
Interventional radiography provided a minimally invasive way to manage this unusual vascular anomaly.
