Abstract
BACKGROUND
The aim of this study is to describe surgical findings, treatment and outcome of spontaneous pneumothorax (SP) secondary to suspected migrating vegetal foreign body (MVFB).
METHODS
This retrospective study included dogs with computed tomography (CT) consistent with SP suspected to be secondary to MVFB that underwent thoracic surgery. They were divided into two groups according to whether CT identified (group 1) or only suspected (group 2) an MVFB.
RESULTS
Thirty-seven dogs were included (twenty-one in group 1 and 16 in group 2). An MVFB was identified during surgery in 18 of 21 of cases of group 1 and in 10 of 16 of group 2. An agreement between lobes affected on CT and surgical findings was observed in 34 of 40 lobes. In nine of 37 of cases, a lung perforation was identified without evidence of MVFB. Thirty-nine lobectomies were performed: 15 complete and 24 partial. No recurrence of pneumothorax was observed. In four dogs, a second surgery was necessary to remove an MVFB 1.5 to 3 months after the initial surgery due to secondary draining tracts.
CONCLUSION
Surgical approach planed with CT resolved SP in all cases before discharge with excellent short-term outcome and no major complication. CT was reliable to assess perforated lung lobes in 85% of cases. Clinical signs of delayed draining tract developed in 33% of cases where surgery failed to find an MVFB identified on CT.
