The result in the case of a saddle thrombus (an embolism at the base of the aorta) is that it cuts off the blood supply––mostly to the back legs, which is an extremely painful condition. 90% of saddle thrombus cases have underlying heart disease.
.
Consequently, why is saddle thrombus painful?
In cats, these blood clots can travel downstream and become lodged in the femoral arteries -- the main arteries that provide blood flow to the hind limbs. When a saddle thrombus occurs, there is a loss of blood flow to the hind legs causing pain, decreased pulses, cold limbs and paralysis.
Likewise, what is saddle thrombosis? Saddle thrombus (or saddle thrombosis) is a blood clot that started off in the left atrium of the heart and then moved out into the aorta (hence the term aortic thromboembolism). Once there, the clot travels to the junction of the aorta and into the iliac arteries where it gets stuck.
Accordingly, do cats recover from saddle thrombosis?
The cat will need heart medication, blood thinners, and nursing care while the rear legs recover. Median survival of saddle thrombus cats with heart failure is 77 days while median survival of saddle thrombus cats without heart failure is 223 days. About 5% of cats will have tissue damage appearing as an open wound.
What causes saddle thrombosis?
72 percent of cats with a saddle thrombus have both rear legs affected. The saddle thrombus comes from a larger clot in the left atrium of the heart. In fact, 89 percent of cats with a saddle thrombus have heart disease. Heart disease leads to turbulent blood flow which encourages the formation of clots.
Related Question AnswersCan saddle thrombus be prevented?
Prevention. There is no known mode of prevention for most of the cardiac diseases that predispose cats to saddle thrombus formation.Is saddle thrombosis hereditary?
Aortic Thromboembolism in Cats Therefore, complications arising in the aorta can be very serious. Aortic thromboembolism, also referred to as saddle thrombus, is more common in cats in comparison to dogs, and it is believe to be hereditary in nature.Why would a cat not walk?
When a cat is experiencing paralyzation, it is often because communications between the spinal cord and the brain have been disrupted.

full rear leg paralysis is called paraplegia, but some cats only show partial paralysis symptoms.

- Circling.
- Weakness.
- Head pressing (possibly as a result of a headache)
- Not using the legs normally (sometimes on one side of the body)
- Unsteadiness when walking.
- A head tilt.
- Abnormal eye movements.
What causes feline aortic thromboembolism?
Therefore, 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.What is an arterial clot?
Arterial thrombosis is a blood clot that develops in an artery. It's dangerous as it can obstruct or stop the flow of blood to major organs, such as the heart or brain. If a blood clot narrows one or more of the arteries leading to the heart, muscle pain known as angina can occur.How do cats get water in their lungs?
Pulmonary Edema in Cats. Pulmonary edema refers to fluid buildup in the lungs and is often associated with pneumonia, although there are many other possible causes.

Thromboembolism is a fairly common and potentially devastating complication of heart disease in cats. Aortic thromboembolism (ATE) is a disease process whereby a thrombus is formed, typically in the left atrium. 1,2 Neoplasia and thyroid disease have also been associated with ATE.How is hypertrophic cardiomyopathy treated in cats?
Ultimately, the goals for treatment of HCM in cats include:- Medications to slow the heart rate, correct abnormal heart beats, and improved blood flow and cardiac function.
- Medications to decrease blood clot formation.
- Medication to alleviate fluid build-up with congestive heart failure.
