In dogs with pulmonary thromboembolism, dyspnea and arterial hypoxemia are consistent findings, often associated with multiple underlying disease processes such as cardiac disease, neoplasia, or sepsis.
May support comorbidity screening in older dogs with dyspnea and hypoxemia; leaves open prospective validation for pulmonary thromboembolism.
Medical records of 47 dogs with pulmonary thromboembolism were reviewed. Middle-aged to older dogs predominated and dyspnea and arterial hypoxemia were consistent clinical findings. Thoracic radiographic findings were variable. Cardiac disease, neoplasia, hyperadrenocorticism, disseminated intravascular coagulation, and sepsis were identified most frequently. Multiple disease processes were identified in 64% of the dogs.
