Abstract

Objective: (1) To report signalment and outcome data from dogs and cats undergoing pneumonectomy; and (2) to document presenting clinical signs, surgical complications, histologic diagnosis, and postoperative complications. 
Study Design: Retrospective, multicenter study. 

Sample Population: Seventeen dogs and ten cats. 

Methods: Signalment, clinical signs, side affected, surgical data, pre-operative diagnostic tests (including complete blood count, serum biochemistry, cytological diagnosis, chest radiographs and computed tomography), histopathologic diagnosis, surgical complications, adjunctive therapy, and date and cause of death were collected from records of dogs and cats that underwent pneumonectomy. Survival estimates, and complication were assessed. 

Results: Seventeen patients had a left-sided pneumonectomy performed (12 dogs and 5 cats) and ten patients had a right-sided pneumonectomy (5 dogs and 5 cats). Fourteen patients were diagnosed with neoplasia (52%). The overall incidences of complications were 76% and 80% for dogs and cats, respectively. The incidences of major complications were 41% and 50% for dogs and cats, respectively. Respiratory complications (persistent pleural effusion, oxygen dependence, persistent increased respiratory rate or coughing) were the most commonly reported complications. 
No patients died or were euthanized intraoperatively or within the first 24 hours post operatively. However, one dog (6%) and 2 cats (20%) died or were euthanized in the first 2 weeks post-operatively. 

Conclusion: Based on this small cohort, right and left pneumonectomy can be performed with a relatively low perioperative mortality rate in dogs and cats, with some animals experiencing prolonged survival.
