SURGICAL-MANAGEMENT OF EXTRATHORACIC TRACHEAL COLLAPSE IN 2 LARGE-BREED DOGS

Collapse of the cervical portion of the trachea was diagnosed for 2 yo ung large-breed dogs. Clinical signs included worsening respiratory st rider and coughing exacerbated by exercise. The diagnosis was confirme d by use of conventional radiography and fluoroscopy of the trachea. A polypropylene, spiral ring, extraluminal, tracheal prosthesis was use d to successfully treat tracheal collapse in each dog. Although trache al collapse typically affects middle-aged and old small-breed dogs, tr acheal collapse should be considered as a differential diagnosis for l arge-breed dogs with a honking cough and respiratory stridor.
