Splenic Torsion in Cats

The spleen exists as a main support to the immune system. It acts as a filter to destroy excess red blood cells, and as a reservoir for blood. Splenic torsion, or twisting of the spleen, may occur by itself, or in association with gastric dilatation-volvulus (GDV) syndrome, when a cat's air-filled stomach expands and twists on itself. It can occur suddenly, or it can gradually twist over a period of time. Being affected by an abnormality such as splenic torsion is rare.

Symptoms and Types

• Intermittent lack of appetite
• Vomiting
• Weight loss
• Red to brown colored urine
• Abdominal pain
• Pale gums
• Increased heart rate
• Abdominal mass that can be felt

Causes

• Prior gastric dilatation, and volvulus (abnormal expansion, and twisting of the intestinal or gastric organs)
• Excessive exercise, rolling, and retching may contribute
• Nervousness and anxiety have been associated with an increased risk of GDV 

Diagnosis

Your veterinarian will perform a complete physical exam on your cat, including a blood chemical profile, a complete blood count, a urinalysis and an electrolyte panel. You will need to give a thorough history of your cat's health, onset of symptoms, and possible incidents that might have precipitated this condition.

A coagulation test may show prolonged bleeding times, which would indicate a disseminated intravascular coagulopathy (clotting within multiple veins throughout the system), a serious end-stage disease of the cardiovascular system.

Abdominal x-ray images may reflect a mass, and/or an abnormally located spleen. An abdominal ultrasound may be used for a more sensitive imaging of the spleen. Your veterinarian may also want to use an electrocardiogram to trace blood flow, a blockage in the flow may show as arrhythmias of the heart.
