Bronchoscopy, Imaging, and Concurrent Diseases in Dogs with Bronchiectasis: (2003-2014)

Area of Science:

• Veterinary Medicine
• Pulmonology
• Diagnostic Imaging

Background:

• Bronchiectasis is a permanent airway condition resulting from chronic or severe injury.
• Diseases associated with bronchiectasis in dogs are not well-defined.

Purpose of the Study:

• To assess the effectiveness of diagnostic tests for bronchiectasis in dogs.
• To characterize the underlying or concurrent diseases associated with canine bronchiectasis.

Main Methods:

• A retrospective case series of 86 dogs diagnosed with bronchiectasis after bronchoscopy.
• Evaluation of radiographs, computed tomography (CT), and bronchoscopic findings.
• Diagnosis of concurrent conditions like pneumonia, eosinophilic bronchopneumopathy (EBP), and inflammatory airway disease (IAD) based on clinical data and diagnostic testing.

Main Results:

• Bronchiectasis was diagnosed in 14% of dogs undergoing bronchoscopy.
• Bronchoscopy confirmed bronchiectasis in 92% of cases; CT was 100% sensitive.
• Pneumonia (52%), Eosinophilic Bronchopneumopathy (12%), and Inflammatory Airway Disease (36%) were common concurrent diagnoses. Bacterial infections were identified in 28% of cases.

Conclusions:

• Bronchiectasis should be suspected in dogs with infectious or inflammatory respiratory conditions.
• Advanced imaging and bronchoscopy are crucial for diagnosing bronchiectasis and identifying co-existing respiratory diseases in dogs.
