Aortic thrombo-Embolism in cats – a tragic condition

I had the tragic task of dealing with a case of aortic thrombo-embolism in the emergency clinic at the weekend, in a beautiful cat who had been presented by her owner after suddenly going off her back-legs.

This condition, which results in a blood clot forming and blocking the major blood vessels to the legs – most usually at the point where the body’s main artery, the aorta, branches to supply the hindlimbs – results in cat suddenly losing the use of their back legs, with the legs often feeling cold to the touch and with the absence of any normal sensation. This was confirmed when I performed a test to see whether there was any blood flow to the back legs by making a small needle impression in the pads (which normally results in a small spot of blood, as you would get if you pricked your finger with a needle) and by cutting the nail back past the quick, which is the equivalent of the very tip of our fingers and usually results in bleeding. The absence of any blood after both these tests confirmed the diagnosis and as a result the decision was made to put the cat to sleep.

There can be many reasons for such a clot to form in cats, with the most common reason being an underlying heart condition which if left undiagnosed and untreated can result in abnormal blood flow and potentially a clot forming, with some devastating and sudden effects. It is therefore important to ensure that you take your cat to the vet for regular check-ups, which will include the vet listening to their heart. Sometimes, however, as in the case yesterday, there is no apparent reason and it it just makes the situation that much more tragic.
