Aortic Thromboembolism in Cats
An aortic thromboembolism results when a blood clot is dislodged and travels through the aorta, becoming lodged in a distant location. This causes severely reduced blood flow to the tissues receiving blood from that particular part of the aorta, leading to decreased oxygen in the tissues. Mixed breed cats, Abyssinian, Ragdoll, and Birmans are the most commonly affected. Sudden paralysis and pain, usually in the rear legs, are the most common clinical signs of aortic thromboembolism, although weakness and lameness may be seen. Other signs may include decreased or absent pulses in the femoral arteries of the rear legs, rapid breathing or difficulty breathing, vocalization from pain, vomiting, and the nailbeds and footpads may be pale or bluish. Initially, cats may need to be treated as inpatients. Drugs to prevent platelets from clumping together will be prescribed. The expected course of this disorder is days to weeks for full recovery of function to the legs, but the prognosis in general is very poor.
