A 13-month-old neutered female American domestic shorthair cat was presented for evaluation of bilateral pelvic limb lameness of 9 months' duration. A diagnosis of bilateral stifle osteochondritis dissecans was made from the physical and radiographic examination findings. Cartilage fragments and flaps were found in both stifle joints during bilateral stifle arthrotomy. The affected subchondral bone was curetted. The clinical signs improved after this surgical treatment, and the cat had a normal range of motion in both stifle joints on the physical examination 3 years postoperatively.
A 13-year-old male miniature Dachshund was presented for evaluation of voiding difficulty. Prostatic inflammation or a tumor was suspected after a series of diagnostic imaging examinations, but biopsy by transabdominal cystoscopy revealed a fibrous foreign body obstructing the prostatic urethra. A laparotomy was performed to remove the obstruction, and the symptom subsided postoperatively. Because the dog had previously undergone surgical repair of a perineal hernia, we concluded that a piece of cotton used during the surgery had entered the prostatic urethra and caused urethral obstruction.
An 11-year-old male Pekingese was presented with chronic coughing and swelling of the ventral cervical region on expiration. A diagnosis of dynamic cervical lung herniation was made based on thoracic radiographic findings. The hernia was repaired in two surgical operations. Transposition of the sternocephalicus muscle was performed in the first operation, which resulted in recurrence of the hernia; therefore, polypropylene mesh was used to close the hernia in the second operation. Although the second operation alone was not sufficient to achieve complete reduction, the complementary use of a cervical corset prevented recurrence of the herniation, and a favorable postoperative outcome was obtained.
