Abstract
A 57-year-old patient presented with stridor and dyspnea. Metastases from a thyroid cancer had invaded the trachea over its whole length and eroded the fifth cervical vertebral body. Because of the possibility of transverse section, rigid bronchoscopy could not be performed. After laser photoresection a Silastic tracheal stent was inserted with a flexible bronchoscope. As this endoprosthesis did not solve the problem, it had to be removed using an inflated endotracheal tube. A 12-cm-long bifurcated Dynamic airway stent was inserted with flexible instruments under local anesthesia. Semistiff tube exchangers, fiberoptically placed into the stem bronchi. were used to guide the y-shaped Dynamic stent down until it saddled on the carina. The procedure gave the patient immediate relief from his central airway obstruction.
