Tracheal diameter was calculated from the square root of the product of the major and minor axes at 4 locations: 1 cm caudal to the larynx, the thoracic inlet, the midthoracic trachea, and 1 cm cranial to the carina. Values were averaged to determine predicted stent diameter in situ. The predicted length of the stent placed in each dog was calculated with regression formulas derived from the manufacturer\u2019s information regarding stent diameter and length. Actual stent length following deployment was determined from stored fluoroscopic images. Predicted stent lengths were compared to actual stent lengths, and the percent error was determined for each patient.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Appropriate images were available for 11 dogs.
