RESPIRATORY DI SEAS E S
Evaluation of Unilateral Arytenoid Lateralization for the Treatment of Laryngeal Paralysis in
14 Cats B Thunberg, GC Lantz
RETROSPECTIVE STUDY Laryngeal paralysis is a relatively common cause of upper airway obstruction in middle-aged to older, large- breed dogs; however, it is rare in the cat. The purpose of this study is to describe a series of cats diagnosed with laryngeal paralysis treated by unilateral arytenoid lat- eralization. Fourteen cats met the criteria of the study. Intraoperative and postoperative complications were seen in 21% (three of 14) and 50% (seven of 14) of cases, respectively. Median duration of follow-up was 11 months (range 3 weeks to 8 years). None of these cats had recurrence of clinical signs. Based on this brief case series, unilateral arytenoid lateralization appeared to be a suitable method for treating laryngeal paralysis in cats. Additional studies are warranted to determine the type and frequency of long-term complications.
INTERNAL MEDIC INE
Syndrome of Inappropriate Antidiuretic Hormone
Secretion in a Cat K Cameron, A Gallagher
CASE REPORT A 3-year-old, spayed female, domestic shorthaired cat was presented for evaluation of liver disease. Following anesthesia, laparoscopy, and medical therapy, the cat developed severe hyponatremia that was unresponsive to fluid therapy. Further evaluation of serum and urine osmolality determined that the cat fulfilled the criteria for syndrome of inappropriate antidiuretic hormone secretion. Treatment with fluid restriction resulted in resolution of the hyponatremia and clinical signs associ- ated with the electrolyte imbalance.
SOFT T ISSUE SURGERY
Successful Treatment of Necrotizing Fasciitis in the Hind Limb of a
Great Dane AB Csiszer, HA Towle, CM Daly
CASE REPORT A 5-month-old, intact female Great Dane was presented for an acute onset of rapidly progressive lameness, severe pain, and diffuse swelling of the right hind limb. Ultrasound evaluation revealed echogenic fluid pockets extending along fascial planes of the right hind limb, from the proximal femur to the hock. Necrotic soft tis- sues were debrided, and closed-suction drains were placed. No foreign material was identified at surgery. Fluid culture identified a beta-hemolytic Streptococcus sp., and affected fascial histopathology was consistent with necrotizing fasciitis. Postoperatively, the puppy was managed with intravenous broad-spectrum antibiotics, local infusions of amikacin, and daily physical rehabilita- tion. Oral pentoxifylline was administered to treat bron- chopneumonia and streptococcal toxic shock syndrome that developed secondary to necrotizing fasciitis. To our knowledge, this is the first report of a successfully man- aged case of beta-hemolytic, streptococcal, necrotizing fasciitis successfully managed after a single surgical debridement in combination with systemic broad-spec- trum antibiotics, local amikacin infusion, active closed- suction drainage, daily cytology, massage, and passive range-of-motion exercises to maintain limb function.
