Tracheal perforation is a loss of the integrity of the tracheal wall, in the form of a hole or rip, allowing leakage of air into the surrounding tissues and creating air pockets under the skin, air collection in the mediastinum (in between the lungs), and potentially air in the sac around the heart, free air in the chest cavity, and air in the most posterior part of the abdominal cavity (pneumoretroperitoneum). This loss of integrity can be caused by a penetrating trauma, trauma from inside the trachea, or blunt neck or chest trauma.
The severity of tracheal perforation ranges from a small perforation to complete tracheal avulsion (tearing away of the trachea). In cats with complete avulsion, the mediastinal tissues can help to maintain the airways.
The following signs
The following signsmay occur immediately after injury or up to a week later:
Penetrating cervical (neck) wounds:
Perforation by a veterinarian (iatrogenic):
Blunt trauma can cause intrathoracic tracheal avulsion:
The prediction of a disease’s outcome in advance
The puncturing of a hole in the wall of the chest as a means of drawing out fluid or air
An in-depth examination of the properties of urine; used to determine the presence or absence of illness
A medical condition in which gas or air collects in the pleural space
The windpipe; it carries air from the bronchi to the mouth
The membrane that covers the wall of the abdomen and pelvic area
The tearing or breaking away of a part.
Anything that is created through a method of treatment
The area in the thorax between the two lungs, where the heart, esophagus, aorta, bronchials, and thymus are located.
The space in the abdomen that holds the major digestive organs in an animal. Normally referred to as the area between the diaphragm and the pelvis. Also referred to as the peritoneal cavity.
