If it is determined that a limb requires amputation surgically, your veterinarian will perform a urinalysis, blood chemistry and blood count to determine overall health of your pet and, if amputation is not urgent, treat or address any conditions required prior to surgery.
If cancer is present, biopsies of any tumors will be performed prior to limb amputation to determine the type of cancer and the risk of metastasizing. In addition to biopsies, X-rays may be taken to determine if tumors have spread to other parts of the body.
You will be required to have your pet fast and restrict fluid the night before the surgery. When you arrive at the veterinarian they will use intravenous anesthesia to put your cat into a deep sleep prior to inserting a tracheal tube that will be used to maintain the anesthesia with gas. The area to be treated surgically will be shaved and cleaned and surgical drapes used to maintain the sterile area for surgery.
Your veterinarian will perform surgery to remove the limb and ensure that all vascularization is attended to. Most foreleg amputations involve the entire limb up to the shoulder (scapulothoracic disarticulation) . If a hind leg is being removed it may either be performed at the hip joint or the upper part of the femur (high femur) which will leave a short stump.
The surgical area will be sutured and the wound bandaged. Antibiotics may be administered prior to surgery and post surgery to prevent infection, if deemed necessary. Your cat will be required to wear an Elizabethan collar to prevent them licking or biting the wound or sutures.
