Bronchoscopy is a procedure done by an Internal Medicine specialist to evaluate the trachea, bronchi and lower airways. The procedure is done with your pet under general anesthesia after he/she has not eaten for 12 or more hours.While anesthetized, a flexible digital endoscope is passed through your pet’s mouth into his/her trachea and down into the lungs. The Internal Medicine specialist is able to view an image of your pet’s airway on a digital video screen. A biopsy instrument or tiny brush can be passed through the endoscope for the purpose of obtaining small samples of the tracheal or bronchial wall. Often small amounts of sterile saline are flushed through the scope and into the lower airway, then immediately retrieved by suction. This is called a bronchoalveolar lavage (BAL) and allows the specialist to obtain samples of tissue and cultures of the lower lung or airway.
