Tracheal collapse is a chronic, progressive, irreversible disease of the trachea, or windpipe, and lower airways (mainstem bronchi collapse).The trachea is a flexible tube and, similar to a vacuum cleaner hose. It has small rings of cartilage that help keep the airway open when the dog is breathing, moving or coughing.racheal collapse is a chronic, progressive, irreversible disease of the trachea, or windpipe, and lower airways (mainstem bronchi collapse).
Background. Tracheomalacia is a process characterized by flaccidity of the supporting tracheal cartilage, widening of the posterior membranous wall, and reduced anterior-posterior airway caliber.These factors cause tracheal collapse, especially during times of increased airflow, such as coughing, crying, or feeding.1, 2, 3] Tracheomalacia most commonly affects the distal third of the trachea and can be associated with various congenital anomalies, including cardiovascular defects, developmental delay, gastroesophageal reflux, and tracheoesophageal fistula.
