RESEARCH COMMUNICATIONS OF THE 28th ECVIM-CA CONGRESS

Twelve dogs, different in age, sex and breed, who died spontaneously for reasons other than pulmonary diseases, were included in the study, with owners’ consent, and distinguished by weight in 3 groups (<10, 10‐25, >25Kg). All the subjects were examined endoscopically in a systematic manner with a HD flexible endoscope (Ø6mm). The endoscopy focused on intracorpore (IC) and extracorpore (EC) exam. The EC was performed after the isolation of the lungs in order to obtain a better examination of cranial lobes, difficult in IC for their orientation. We considered the visualisation and the ability to pass through the lumen of each branch with the endoscope. After that, on the same lungs, casts of polyurethane foam were made and diameter and length of the bronchial branches were measured through a digital calliper. Furthermore, to name the structures and to draw the bronchial map, we defined them by looking at their direction and position.
