Feline aortic thromboembolism

Aortic thromboembolism is one of the most serious and difficult-to-manage complications. of feline cardiac disease. Most, but not all, cats presenting with signs of aortic thromboembolism are found to have underlying cardiac disease at the time of presentation. In most cases no underlying disease has been diagnosed prior to presentation with paresis/paralysis and profound anxiety. This article will review commonly used treatments for thromboembolism and agents proposed for prophylaxis. Many of the proposed treatments are themselves associated with a high morbidity rate and long term clinical trials are required to make comparative risk-to-benefit ratio assessments of these different options. In cats which do survive the initial treatment, clinicians are still faced with the perplexing problem of long term thrombus prevention, as a majority of cats have been shown to re-embolise despite prophylaxis.
