Splenic Torsion (Twisted Spleen) in cats

Occurrence: very rare
Location of illness: Abdomen/pelvis

Splenic torsion in cats refers to the pathological twisting of the spleen, which leads to an interruption of the blood supply and possible damage to this organ.

The most important facts at a glance

Splenic torsion in cats occurs when the spleen twists on its own axis, which can impair blood flow and lead to tissue damage. The exact causes are not fully understood, but increased mobility of the spleen, splenomegaly, or sudden movements can be risk factors. Symptoms include loss of appetite, vomiting, abdominal pain, and a palpable mass in the abdomen. Diagnosis is made by clinical examination and imaging procedures such as ultrasound or X-ray. Blood tests can also be helpful to rule out other causes of the symptoms.

Treatment usually consists of a splenectomy, in which the spleen is removed. Stabilization of the cat may be necessary before surgery, especially if it shows signs of shock. After surgery, regular check-ups and possibly antibiotics are important to avoid complications. The prognosis depends on the speed of treatment, but is often good with early intervention. In the long term, cats can lead a normal life without a spleen, but may be more susceptible to infections. For prevention, cats should receive a balanced diet and undergo regular veterinary examinations. Stress reduction and immediate veterinary consultation for unusual symptoms are also important.

Causes

The spleen is an important organ in the immune system of cats, playing a role in filtering the blood and producing lymphocytes. It also helps in the storage and recycling of red blood cells and iron. Anatomically, the spleen is located in the abdomen near the stomach and is connected to other organs by ligaments.

Splenic torsion occurs when the spleen twists on its own axis. This twisting can narrow or completely block the blood vessels that supply the spleen. This can lead to reduced blood flow or complete standstill, which can result in tissue damage or necrosis of the spleen.

The exact causes of splenic torsion in cats are not fully understood. However, it can occur as a result of increased mobility of the spleen, which is favored by injuries or congenital anomalies. In some cases, an enlarged spleen, known as splenomegaly, can also lead to a higher probability of torsion. Splenomegaly can be caused by various conditions, including infections, inflammatory conditions, or tumors.

Risk factors for splenic torsion can also be sudden movements or trauma, although such events are less common in cats than in other animals, such as dogs. A genetic predisposition has not yet been clearly demonstrated, but could play a role in some cases.

Symptoms

Very common symptoms:

Common symptoms:

The symptoms of splenic torsion in cats can vary, depending on how severe and rapidly the torsion progresses. In many cases, the symptoms are non-specific, which can make diagnosis difficult. The most common signs include lethargy and a general malaise, as the cat may experience pain due to reduced blood circulation in the spleen.

Other symptoms may include loss of appetite, vomiting, and diarrhea, which arise from the impairment of normal digestive processes. In some cases, there may also be a visible swelling of the abdomen, caused by the enlargement of the spleen. A cat may also show signs of shock, such as pale mucous membranes, rapid heart rate, and shallow breathing, if the torsion is severe and the blood circulation is severely impaired.

Diagnosis

The diagnosis of splenic torsion in cats requires a thorough clinical examination and the use of diagnostic imaging techniques. Initially, the veterinarian will take a complete history and assess the cat’s clinical symptoms. Palpation of the abdomen may provide evidence of an enlarged or painful spleen.

Imaging techniques such as ultrasound or X-rays are crucial to assess the position and condition of the spleen. An ultrasound can help visualize the torsion of the spleen and determine the degree of blood flow disruption. In some cases, a computed tomography (CT) scan may also be required to obtain a more detailed view.

In addition, blood tests can be performed to assess the cat’s general health and rule out other possible causes of the symptoms. These tests can reveal signs of anemia, inflammatory conditions, or infection.

Therapy

Treatment of splenic torsion in cats usually requires surgery to correct the torsion and restore normal blood circulation to the spleen. This can be achieved through a procedure called splenectomy, in which the spleen is removed. Although the spleen plays an important role in the immune system, cats can live without this organ, as other organs can partially take over its functions.

Stabilization and supportive care may be required prior to surgery, especially if the cat shows signs of shock. This may include the administration of intravenous fluids, pain relievers, and other supportive therapies.

Post-operative care is also important to avoid complications and support the cat’s recovery. This includes regular check-ups and, if necessary, the administration of antibiotics to prevent infections.

Prognosis and follow-up care

The prognosis for cats with splenic torsion depends on various factors, including the severity of the torsion and the speed of treatment. With early diagnosis and successful surgical intervention, the prognosis is generally good, and many cats recover completely.

However, complications can occur, especially if the torsion has led to significant tissue damage or necrosis of the spleen. In such cases, recovery may take longer, and there may be an increased risk of post-operative infections or other complications.

In the long term, cats without a spleen can lead a normal life, although they may be more susceptible to certain infections. Therefore, regular veterinary care and monitoring is important to ensure the health of the cat.

Prevention

To minimize the risk of splenic torsion in your cat, it is important to pay attention to a balanced diet and a healthy weight. Overweight can increase the risk of various health problems, including splenic torsion. Feed your cat high-quality food in appropriate portions and avoid excessive treats.

Regular veterinary examinations are also crucial to monitor your cat’s general health and detect potential problems early. Talk to your veterinarian about your cat’s specific needs, especially if it belongs to a breed that may be more prone to such conditions.

Stress reduction is another important factor. A calm and stable environment can help minimize stress in your cat. Make sure she has enough retreat options and encourage regular exercise to support both physical and mental health. Be sure to avoid sudden changes in the environment or routine that could trigger stress.

Finally, it is important to consult a veterinarian immediately for any unusual behavior or symptoms. Early detection and treatment can be crucial to avoid serious complications.

Outlook on current research

Splenic torsion in cats is a relatively rare condition that is receiving increasing attention in veterinary medical research. While splenic torsions are more common and well-documented in dogs, especially in large breeds, there is less data and fewer studies in cats. Recently, however, research has focused on better understanding the causes, diagnostic methods, and treatment options for this condition in cats.

One area of research is investigating the anatomical and physiological differences between cats and dogs that may contribute to the different frequency of splenic torsions. Researchers are trying to understand why the spleen is less susceptible to torsions in cats and what factors might play a role in the rare cases that do occur. These studies involve examining the spleen structure, its blood supply, and its attachment points in the body.

Another important research focus is the development of improved diagnostic techniques. Traditionally, splenic torsion is diagnosed by physical examination and imaging procedures such as ultrasound or X-ray. Researchers are working to increase the accuracy and efficiency of these methods, possibly through the use of more advanced technologies such as magnetic resonance imaging (MRI) or newer ultrasound techniques that allow for more detailed visualization of the internal organs.

In addition, efforts are being made to identify the best treatment approaches. While surgical removal of the spleen (splenectomy) is the most common treatment method, alternative approaches are being explored that are less invasive and allow for faster recovery. Some studies focus on the possibility of stabilizing the spleen in its position without removing it, which could potentially improve the cat’s quality of life.

Finally, the genetic predisposition to splenic torsions in cats is also being explored. Researchers are investigating whether certain breeds or genetic lines are more susceptible to this condition and whether genetic tests could be developed to identify at-risk animals early on. In the long term, this could help develop breeding strategies that minimize the risk of splenic torsions.
