Feline Splenectomy

A feline splenectomy is the removal of a cat's spleen. The spleen is located in the abdomen and can be removed without causing future health problems in your cat. In determining if your cat requires a splenectomy the veterinarian performs several tests such as blood and urine tests, abdominocentesis, X-rays or an ultrasound. Each of these tests determine if the spleen is damaged or diseased and will help the veterinarian decide if a feline splenectomy is necessary.

  1. Requirements

    • Feline splenectomies are performed usually when there is twisting in the blood vessels supplying the spleen, an infected spleen, tumors on the spleen or trauma to the spleen. Trauma to the spleen can result from kicking, falling from a high place or being hit by a car. If the splenectomy is associated with tumors, trauma or bleeding, additional tests such as blood count, radiographs, urinalysis and an EKG may be necessary.

    Surgery

    • During a feline splenectomy, the cat is laid on its back on a surgical table. The fur on the abdomen is clipped and the area is scrubbed to disinfect it. The veterinarian uses a scalpel to cut the abdominal skin and open the abdominal cavity. Blood vessels going to the spleen are tied off and the spleen is then removed. The abdominal incision is closed with stitches or surgical staples.

    Recovery

    • Some cats may be hospitalized for several days to one week following a splenectomy. When you cat returns home, follow the instructions given by your veterinarian regarding post-operative care. Restrict the cat's activity until the stitches are removed in 10 to 14 days. Pain medication may be prescribed and your cat should be checked frequently for bleeding and anemia. Watch for signs of infection such as pain, discharge, swelling or redness.

    Tumor-Related Splenectomy Follow-Up

    • If a feline splenectomy is associated with a tumor, depending on the biopsy results, chemotherapy or another such treatment may be recommended. Survival time for a cat after a cancer-related splenectomy is 14 months. Survival time without a splenectomy is six months. The splenectomy does not always cure the cat, but it removes a significant number of tumor cells quickly and the remaining cells take time to regrow and form another tumor.
