Prior to reconstructive surgery your veterinarian may perform routine tests to determine your cat's overall health and likely success of reconstructive surgery or risk from anesthesia. Occasionally, treatment of the wound prior to surgery will be necessary to optimize the chance of successful reconstruction by ensuring tissue is as healthy as possible. Treatment may involve medication or bandaging to optimize the condition of the wound prior to the procedure. The wound must be clean, free of infection, and granulation of tissue present in order for reconstructive surgery to have the best outcome. The night prior to surgery your cat will need to fast to reduce the risk of aspiration during surgery. When your cat arrives at the veterinarian on the day of surgery, they will be examined to ensure that bacterial infection is not present. Your cat will be given a sedative, intravenous anesthesia, and then have a breathing tube inserted to maintain anesthesia by gas. The wound will be cleaned and hair, dirt and other contaminants removed from the surgical area. If emergency trauma had occurred, supportive treatment such as intravenous fluids may be necessary.
Reconstructive Surgical techniques that may be performed on your cat include:
Suturing and Other Surgical Techniques
Specialized sutures, such as tension relieving sutures, may be placed at the wound site. Tension relieving sutures are a pattern of sutures that hold skin edges together where there is a lot of tension, or a tight closure over the wound. These sutures relieve the stress on the skin and allow for better circulation and healing.
Wounds on joints may be aggravated by constant motion; a veterinary surgeon may make an incision on the opposite side of the joint to release tension and allow the skin on the opposite side to close over the wound located at a joint. The incision made will heal on its own.
Skin Flaps
Because skin can be manipulated and stretched, skin that is located next to the open wound can be lifted from its natural bed and manipulated, rotated and stretched to cover the open wounds. In order for this to work, loose skin adjacent to the wound needs to be available. If this is not the case, skin adjacent to the wound can be stretched prior to surgery by using expanding devices under the skin, or bands on the surface of the skin.
Skin Grafts
When adjacent skin is not available, skin can be removed from one part of the body and transported to the open wound site where it can be sutured in place. Sometimes surgical mesh may be used to facilitate this by providing a binding site and structure for the grafted skin to bind to.
Reconstruction may require more than one surgical procedure to achieve the desired results.
If reconstructive surgery is being conducted at the same time as tumor removal, your veterinarian will change gloves and instruments between surgeries to minimize the risk of contamination by neoplastic (abnormal cell) tissues.
Hospitalization and cage rest may be recommended for a short time to ensure that healing begins before your cat is sent home for recovery. Pain medication and antibiotics will be administered as required.
