Surgical Conditions

  • Cholangitis/cholangiohepatitis in cats refers to inflammation of the bile duct or a combination of inflammation of the bile duct, gallbladder, and surrounding liver tissue. The clinical signs, diagnosis, treatments, and prognosis of the conditions are outlined in this handout.

  • Collie Eye Anomaly (CEA) is a genetic mutation affecting many breeds that causes developmental defects in the eye that can lead to vision deficits or blindness. This defect can be diagnosed by a veterinary ophthalmologist between 6 and 8 weeks of age by visualizing spots of choroidal hypoplasia or a colobomas . It can be associated with microphthalmia or enophthalmia. It can lead to retinal detachment and blindness. Although laser repair of partial retinal detachments can be attempted if detected in early stages, there is generally no treatment for CEA. Vision varies depending on the extent of the lesions and some dogs will become blind. Prevention requires not breeding animals that carry the mutation and this can be achieved through genetic testing of breeding dogs.

  • Ulcerative keratitis is inflammation in the cornea of the eye. The signs of ulcerative keratitis depend somewhat on the cause and how long the condition has been present. There are many potential causes of ulcerative keratitis, including trauma, infection, and abnormal tear production. Antibiotic ointment or drops will be prescribed and it is important to prevent additional trauma to the cornea. Superficial corneal ulcers typically heal within 5 to 7 days. Deeper or more complicated ulcers may take several weeks to heal and may require surgery in addition to medical treatment.

  • The traditional extracapsular lateral suture ECLS technique is the oldest surgical correction for cranial cruciate ligament (CCL) injury in dogs. The name of the procedure originates from the fact that the joint is stabilized outside the joint capsule (externally). CCL repair surgery typically begins with an initial examination of the inside of the knee. Both the traditional ECLS and the Tight Rope® procedures are considered extracapsular or external repairs of CCL injury. Both yield similar results with similarly low risks.

  • One of the most common injuries to the knee in dogs is tearing of the cranial cruciate ligament (CCL). When the cranial cruciate ligament is torn, surgical stabilization of the knee joint is often required. The development of tibial plateau leveling osteotomy or TPLO was a major advancement in the treatment of CCL rupture. Healing from TPLO surgery is generally rapid, with the dog resuming normal activities quickly.

  • One of the most common injuries to the knee in dogs is tearing of the cranial cruciate ligament (CCL). Several surgical techniques are currently used to correct CCL rupture. The TTA procedure is more commonly performed in dogs with a steep tibial plateau (angle of the top part of the tibia). Healing from TTA surgery is generally rapid and dogs resume normal activities quickly.

  • This handout outlines cruciate ligament rupture, an orthopedic condition, in cats. The common causes, clinical signs, diagnosis, and treatments are described.

  • The cruciate ligaments are two bands of fibrous tissue located within each stifle joint. They join the femur and tibia together so that the knee works as a stable, hinged joint. The two most common causes of cranial cruciate rupture are trauma and degeneration of the ligaments within the joint. There are various surgical techniques to stabilize the knee joint following cruciate rupture. Regardless of the technique used to stabilize the joint, arthritis is likely to develop in the joint as your dog ages.

  • Cryosurgery (or cryotherapy) is the application of extreme cold to destroy abnormal or diseased tissue. In animals, the technique is used to treat tumors in locations where conventional surgery would be difficult or impossible. Cryosurgery is sometimes also used for the removal of aberrant or extra eyelashes (distichiasis).

  • A cutaneous histiocytoma is a common benign (harmless) tumor of the skin in dogs, typically younger ones. Their development, appearance, diagnosis, and treatment are explained in this handout.
