Endoscopic Bronchial Anatomy in the Cat

The aim of this paper is to define the endoscopic bronchial anatomy of the cat and to adapt these findings to the bronchoscopic nomenclature previously described for the dog by Amis and McKiernan (Amis TC, McKiernan BC (1986) Systematic identification of endobronchial anatomy during bronchoscopy in the dog. American Journal of Veterinary Research47(12), 2649–2657). In this study, the normal endoscopic bronchial anatomy was identified based on analysis of 10 air-dried feline lungs, two euthanased and eight healthy anesthetized cats using either a rigid or a flexible endoscope. Endoscopic photographs were taken during the examinations in the anesthetized cats for a photographic atlas. Corrosion casts were made from the 10 air-dried lungs to confirm the anatomy identified by bronchoscopy. With the results of our findings a bronchoscopic map of the feline bronchial tree and a photographic bronchoscopic atlas of the healthy cat were made.
