From: The strategy of removing tracheal stents by using an interventional technique under fluoroscopy
A 61-year-old man with tracheal stenosis due to postoperative recurrence of esophageal cancer underwent uncovered tracheal stent implantation for more than 3Â months. Two months previously, the patient experienced dyspnea again, and bronchoscopy showed a large number of new organisms protruding into the metal mesh stent. A month ago, a covered stent was inserted into the original stent by the intervention technique. DSA (A) showed that the two tracheal stents were completely expanded in the main trachea. DSA (B) showed that stent-removal hook hooked the lower end of the inner tracheal stent. DSA ( C) showed that inner tracheal stent was removed by internal stripping method. DSA (D) showed that external tracheal stent was removed by internal stripping method. The two stents were successfully removed. The patient's dyspnea improved significantly
