Clinical significance: Presence of pseudoflail, rib fracture, or pneumothorax should
raise suspicion of intrathoracic injury. Strong
consideration should be given to radiography,
surgical exploration, and debridement of all
thoracic dog bite wounds.

for lung lobe torsion (LLT) and to determine
prognostic factors for survival.
Lesnikowski S et al.
Study design: Retrospective multicenter study
from four veterinary teaching hospitals.
Background: Dogs with tracheal stents
often have positive airway bacterial cultures.
The pathogenicity of these organisms and
risk factors for infection have not been
Animals: Dogs (n = 80) with LLT.
Methods: Medical records were reviewed
for clinical and histopathological findings.
Long-term outcome was assessed with an
owner questionnaire. Lung lobe torsion was
classified as idiopathic or secondary on the
basis of the etiology.
Results: The most represented breeds were
pugs (47.5%) and sighthounds (16.2%). The
cause of the LLT was considered primary
in 77%, secondary in 21%, and unknown
in 2% of dogs. Postoperative complications
were recorded in 14% of dogs. Overall, 95%
of dogs survived to discharge, and median
follow-up was 1095 days (range, 7-3809).
Owners assessed outcomes and quality of
life as excellent in 93% and 89% of dogs,
respectively. Primary LLT was associated
with a longer survival (median not reached
in the study) compared with secondary LLT
(921 days; range, 7-2073; P = .001).
Conclusion: Overall long-term survival after
lung lobectomy for LLT was excellent. Primary
LLT was associated with longer survival
compared with secondary LLT. Long-term

Objective: Describe bacterial infection in
dogs with tracheal collapse before and after
tracheal stent placement.
Animals: Fifty-three client-owned dogs.
Methods: Retrospective review of medical
records of dogs receiving tracheal stents
with thoracic radiographs, tracheoscopy, and
Results: There was no difference between
the overall prevalence of dogs with positive
bacterial cultures before (31/38; 82%) or
after stent placement (24/31; 77%) (P= 0.67).
An increased number of geriatric (17/28;
61%) and traditional-type collapse (TTC)
(16/26; 62%) dogs had positive pathogenic
airway infections before stent placement,
compared to young (8/25; 32%; P = 0.04)
and malformation-type collapse (MTC)
dogs (9/27; 33%; P = 0.04). After tracheal
stent placement, geriatric dogs had a 52%
