Saddle thrombus, a condition that affects cats, is a blood clot that forms in the aorta, the main artery that carries blood from the heart to the rest of the body. This clot can cause severe pain, paralysis, and even death if left untreated. The condition is called “saddle” thrombus because the clot typically forms at the aortic bifurcation, where the aorta divides into the two main arteries that supply blood to the legs, resembling a saddle. In this article, we will delve into the world of saddle thrombus, exploring its causes, symptoms, diagnosis, treatment options, and management strategies.
Causes and Risk Factors of Saddle Thrombus
Saddle thrombus is often associated with underlying heart disease, particularly hypertrophic cardiomyopathy, a condition where the heart muscle becomes thickened, leading to poor heart function and increased risk of blood clots. Other risk factors include:
Underlying Medical Conditions
Cats with certain medical conditions, such as hyperthyroidism, kidney disease, and cancer, are more prone to developing saddle thrombus. These conditions can increase the risk of blood clots due to inflammation, poor circulation, and other factors.
Genetic Predisposition
Some breeds, such as British Shorthairs and Maine Coons, are more susceptible to saddle thrombus due to their genetic makeup. However, any cat can develop this condition, regardless of breed or size.
Symptoms of Saddle Thrombus
The symptoms of saddle thrombus can vary depending on the size and location of the clot, as well as the individual cat’s overall health. Common symptoms include:
Pain and Discomfort
Cats with saddle thrombus often exhibit severe pain and discomfort, particularly in the hind legs, back, and abdomen. They may vocalize, pace, or show signs of restlessness.
Paralysis and Weakness
As the clot blocks blood flow to the legs, cats may experience paralysis or weakness in one or both hind legs. This can lead to difficulty walking, standing, or even moving around.
Other Symptoms
Other symptoms of saddle thrombus may include cold extremities, poor pulse, and bluish discoloration of the skin. In severe cases, cats may experience respiratory distress or cardiac arrest.
Diagnosis of Saddle Thrombus
Diagnosing saddle thrombus requires a combination of physical examination, medical history, and diagnostic tests. Your veterinarian may perform the following:
Physical Examination
A thorough physical examination can help identify signs of pain, paralysis, or weakness in the hind legs. Your veterinarian may also check for poor pulse, cold extremities, and other symptoms.
Imaging Tests
Imaging tests, such as ultrasound, CT scans, or MRI, can help visualize the clot and determine its size and location.
Blood Tests
Blood tests can help identify underlying medical conditions, such as hyperthyroidism or kidney disease, that may be contributing to the development of saddle thrombus.
Treatment Options for Saddle Thrombus
Treatment for saddle thrombus depends on the size and location of the clot, as well as the individual cat’s overall health. The primary goal of treatment is to restore blood flow to the affected area and prevent further complications.
Medications
Medications, such as anticoagulants and antiplatelet agents, can help prevent further clotting and reduce the risk of complications. Pain management medications may also be prescribed to alleviate discomfort and pain.
Surgery
In some cases, surgery may be necessary to remove the clot and restore blood flow to the affected area. However, surgery is typically reserved for severe cases where the clot is large and life-threatening.

What is a saddle thrombus and how does it occur?
A saddle thrombus is a type of blood clot that forms in the aorta, which is the main artery that carries blood from the heart to the rest of the body. It is called a “saddle” thrombus because it typically forms at the point where the aorta divides into the two main arteries that supply blood to the hind legs, resembling a saddle shape. This type of thrombus can occur in animals, particularly cats, and is often caused by a combination of factors such as blood clotting disorders, heart disease, and atherosclerosis.
The formation of a saddle thrombus can be a life-threatening condition, and it requires prompt veterinary attention. The symptoms of a saddle thrombus can vary depending on the severity of the condition, but they often include pain, weakness, and paralysis in the hind legs, as well as coldness and pale coloration of the affected limbs. In some cases, the thrombus can break loose and travel to other parts of the body, causing further complications. It is essential to seek veterinary care immediately if you suspect that your pet has developed a saddle thrombus, as early treatment can significantly improve the chances of a successful outcome.
