Abstract

Objective—To determine demographic, clinical, and radiographic features of bronchiectasis in dogs.

Design—Retrospective study.

Animals—289 dogs identified through the Veterinary Medical Database (VMDB) and 27 dogs examined at the North Carolina State University Veterinary Teaching Hospital.

Procedure—Demographic characteristics of dogs identified through the VMDB were compared with characteristics of the entire population of dogs entered in the VMDB. Medical records of dogs examined at the teaching hospital were reviewed; the diagnosis was confirmed through review of thoracic radiographs.

Results—Analysis of data from the VMDB indicated that American Cocker Spaniels, West Highland White Terriers, Miniature Poodles, Siberian Huskies, English Springer Spaniels, and dogs > 10 years old had an increased risk of bronchiectasis. Among dogs examined at the teaching hospital, coughing was the most common clinical sign. There was evidence for excessive airway mucus but not hemorrhage. A variety of bacterial organisms were isolated from tracheal wash and bronchoalveolar lavage samples. On thoracic radiographs, cylindrical bronchiectasis, generalized disease, and right cranial lung lobe involvement were most common. Seven of 14 dogs for which follow-up radiographs were available did not have any progression of radiographic lesions. Median duration of clinical signs prior to diagnosis of bronchiectasis was 9 months (range, 1 day to 10 years). Median survival time was 16 months (range, 2 days to 72 months).

Conclusions and Clinical Relevance—Results suggest that despite substantial clinical abnormalities, dogs with bronchiectasis may survive for years. Certain purebred dogs and older dogs may have an increased risk of developing bronchiectasis. (J Am Vet Med Assoc 2003;223:1628–1635)

Abstract

Case Description—4 rabbits (1.5 to 6 years old) were evaluated at the Angell Animal Medical Center from June 2007 to March 2009 because of nonspecific clinical signs including anorexia, lethargy, and decreased fecal output.

Clinical Findings—Physical examination revealed signs of pain in the cranial portion of the abdomen, gas distention of the gastrointestinal tract, and diminished borborygmi. Serum biochemical analyses and CBCs revealed moderately to markedly high alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase activities and mild to moderate anemia with polychromasia. Abdominal radiographic findings were nonspecific. Three of the 4 rabbits underwent abdominal ultrasonography; abnormalities in shape, size, echogenicity, and blood flow of the liver, indicative of liver lobe torsion, were detected.

Treatment and Outcome—All 4 rabbits underwent surgery, during which liver lobe torsion was confirmed and the affected liver lobe was resected. Histologic examination of sections of the excised lobe obtained from 3 of the 4 rabbits revealed severe, diffuse, acute to sub-acute hepatic ischemic necrosis. All rabbits recovered from surgery; owners reported that the rabbits were doing well 22 to 43 months after surgery.

Clinical Relevance—Liver lobe torsions in any species are rarely reported, yet 4 cases of liver lobe torsion in domestic rabbits were treated at 1 referral center in a 2-year period. In rabbits, clinical signs of this condition are nonspecific and results of additional tests, including abdominal ultrasonography and serum biochemical analysis, are necessary for diagnosis. Prompt diagnosis and hepatectomy of the affected lobe are recommended and appear to be associated with an excellent prognosis.
