Abstract

Computed tomographic examination of the trachea was performed on 18 mix-breed dogs. The measurements were taken from 5 segments from which the first 3 segments were extrathoracic trachea, 1 segment at the level of thoracic inlet and 1 segment intrathoracic trachea. The inner and outer transverse and vertical diameters were measured at each of the segments. The cross-sectional area of the lumen, ratio of the inner and outer transverse and vertical diameters were also calculated. It was seen that the diameters and cross-sectional area of the lumen decreased gradually in the extrathoracic trachea from larynx to thoracic inlet but these values showed an increase in the intrathoracic trachea. Correlation coefficients between the inner diameters, cross-sectional lumen areas and the body weight was calculated and a high correlation was found between the inner transverse and vertical diameters and the cross-sectional area of the lumen except between the inner transverse and vertical diameters at the level of S5 segment.
