Splenic bleeding or splenic rupture in pets - Emergency surgery explained

Splenic bleeding or splenic rupture is a life-threatening condition that requires immediate emergency care. The spleen can rupture due to trauma or a tumor, resulting in severe internal bleeding. This can lead to shock and death if not treated quickly. The condition occurs mainly in dogs, often in connection with splenic tumors, but can also occur in cats. 

In this article, we discuss the causes, symptoms, diagnosis, and emergency surgical treatment of splenic bleeding or rupture in pets.

What is splenic bleeding or splenic rupture?

The spleen is a blood-rich organ that plays an important role in immune defense and the breakdown of red blood cells. When the spleen ruptures, this can lead to massive internal bleeding into the abdominal cavity (hemoperitoneum). This is an emergency that requires immediate medical intervention.

Causes of splenic bleeding

• Trauma, for example from being hit by a car or a fall
• Tumors, such as hemangiosarcoma (malignant) or hemangioma (benign)
• Spontaneous rupture of an enlarged or weakened spleen
• Clotting disorders that worsen bleeding

In dogs, a tumor is the most common cause; in cats, trauma is more common.

Symptoms of splenic bleeding

• Acute lethargy or collapse
• Pale mucous membranes (anemia)
• Rapid, weak pulse
• Rapid breathing
• Enlarged abdomen due to blood accumulation
• Signs of shock (low blood pressure, cold extremities, loss of consciousness)

Diagnosis

The diagnosis is based on clinical signs, physical examination, and further testing:

• Abdominal ultrasound to detect free fluid (blood)
• Blood tests often show anemia and clotting abnormalities
• Abdominal puncture (abdominocentesis) can reveal free blood in the abdominal cavity

Treatment: emergency surgery

Treatment of splenic bleeding almost always consists of emergency surgery (splenectomy): removal of the spleen. During the operation, the bleeding is controlled and the abdominal cavity is checked for additional damage or tumor spread. If the bleeding is tumor-related, the tissue is sent for histopathological analysis.

Aftercare and recovery

Intensive aftercare is crucial after surgery:

• Intravenous fluid therapy and blood transfusions if needed
• Monitoring of heart function, blood pressure, and clotting
• Pain relief and antibiotics
• Rest and controlled recovery at home

The prognosis depends heavily on the cause of the bleeding: trauma generally carries a good prognosis, while malignant tumors often carry a poor long-term prognosis.

Prognosis

The prognosis after splenic surgery varies. With traumatic ruptures, the chance of full recovery is high. With tumors such as hemangiosarcoma, the prognosis is often worse (than with a traumatic or benign mass), with limited survival time even after surgery.

Frequently asked questions (FAQ)

What is a splenic rupture?

A tear in the spleen that leads to severe internal bleeding.

What are the symptoms of splenic bleeding?

Sudden lethargy, pale mucous membranes, shock, and a swollen abdomen.

How is splenic bleeding treated?

With emergency surgery in which the spleen is removed (splenectomy).

Does this occur more often in dogs or cats?

In dogs, often due to tumors. In cats, trauma is a more significant cause.

Can an animal live without a spleen?

Yes, animals can live well without a spleen, although immune function decreases slightly.
