Emergency Removal of a Proximal Tracheal Foreign Body by Tracheotomy in a Dog and a Cat

Figure 3

Radiographs of case 2 with a large foreign body (roundish stone) in the proximal trachea. Right lateral cervicothoracic view before surgery reveals increased opacity in the ventral lung field (a) and the stone causing near-complete lumen obstruction (b). Ventrodorsal views demonstrate changes in the right lung opacity before surgery (c), after the first extubation (d), after the positive pressure ventilation before the second extubation (e), and 12 days after surgery (f).
