| Popis: | This retrospective study was undertaken on the records of intraluminal diameter of the trachea in 185 dogs, in which hypoplasia of the trachea had been suspected. The relative size of the trachea was measured using the tracheal diameter (TD), thoracic inlet distance (TI), thoracic tracheal diameter (TT) and the width of the third rib (3R), expressed as ratios TD:TI and TT:3R. Thirty-five dogs were diagnosed as having tracheal hypoplasia. Bulldogs and non-bulldog brachycephalic dogs had significantly smaller measured trachea diameters compared to the predicted values calculated on the basis of their body weight. Radiographs of each dog were investigated by four observers. Inter- and intra-observer reliability (ICCinter, ICCintra) was based on the measurements taken by four observers to evaluate the reproducibility of the protocol. There was a good ICCinter (0.8) and ICCintra (0.89) agreement. Craniocaudal tangential radiographs, centred on the cranial thoracic aperture, did not show a significant difference in tracheal diameter measurements compared to the right lateral radiographs. In conclusion, our findings indicate that bulldogs and non-bulldog brachycephalic dogs have smaller tracheal diameters than non-brachycephalic dogs. |
