Splenectomy in Dogs and Cats
Life-Saving Surgical Removal of a Diseased or Ruptured Spleen
A splenectomy is the surgical removal of the spleen, typically performed when this organ becomes diseased, ruptured, or is affected by a mass. At Whittington Veterinary Clinic, we perform this procedure with precision and care, helping stabilize your pet and improve their quality of life—even without a spleen.
What Does the Spleen Do?
The spleen plays a role in:
- Filtering old or damaged red blood cells
- Supporting immune function
- Storing blood cells for emergencies
While the spleen has important functions, pets can live healthy lives without it when removal is medically necessary.
When Is a Splenectomy Needed?
We may recommend splenectomy for dogs or cats with:
- Splenic masses or tumors (benign or cancerous)
- Ruptured spleen due to trauma
- Internal bleeding from splenic injury or disease
- Hemangiosarcoma — a common malignant tumor in dogs
- Torsion (twisting) of the spleen
- Severe splenic infection or abscess
In many cases, a splenectomy is an emergency procedure due to internal bleeding or collapse.
Signs Your Pet May Need Evaluation:
- Sudden collapse or weakness
- Pale gums
- Swollen or painful abdomen
- Labored breathing or rapid heart rate
- Lethargy or loss of appetite
- Intermittent vomiting or signs of internal pain
If your pet shows these signs, immediate veterinary attention is critical.
What Happens During a Splenectomy?
The procedure is performed under general anesthesia. It includes:
- Pre-operative bloodwork and imaging to assess stability
- Abdominal surgery to identify and remove the spleen
- Control of bleeding and inspection for other issues
- Post-operative pain management, IV fluids, and monitoring
- Optional biopsy of any masses for definitive diagnosis
In emergencies, surgery may be performed immediately to stop internal bleeding and stabilize your pet.
Recovery and Aftercare
Most pets recover well after splenectomy. You can expect:
- Hospitalization for 24–48 hours after surgery
- Pain medications and antibiotics
- E-collar use to prevent licking the incision
- Activity restriction for 10–14 days
- Follow-up visits to monitor healing and discuss pathology results
Pets without a spleen are more vulnerable to infection, so early diagnosis of future illnesses and regular wellness checks are especially important.
