Tracheal collapse in dogs is a condition characterized by incomplete formation or weakening of the cartilagenous rings of the trachea resulting in flattening of the trachea. It can be congenital or acquired, and extrathoracic or intrathoracic (inside or outside the thoracic cavity. Tracheal collapse is most commonly found in small dog breeds, including the Chihuahua, Pomeranian, Toy Poodle, Shih Tzu and Maltese.
Tracheal collapse is a dynamic condition that does not allow for proper oxygenation and can become a emergengy situation without warning. Tracheal stenting provides a minimally invasive, non-surgical method for the treatment of a narrow or obstructed tracheal lumen. A tracheal stent is a self-expanding metallic device which is placed within the trachea (windpipe) and is used to hold the airway open and prevent collapse. Many different considerations must be made when evaluating patients for stent implantation. It is recommended to speak with your vetererinarian in order to see if your pet is a candidate for tracheal stenting.
