From: The strategy of removing tracheal stents by using an interventional technique under fluoroscopy
A 62-year-old female with tracheal stenosis caused by postoperative recurrence of esophageal cancer underwent tracheal covered stent implantation for more than 2 months. The patient subsequently experienced dyspnea for 7 days. CT showed that the tracheal stent had moved downward. DSA (A) showed that the tracheal stent had shifted downward. DSA (B) showed that stent-removal hook hooked the upper end of the tracheal stent. DSA (C–D) showed that the tracheal stent was then removed by direct extraction method, in which the stent-removal hook was attached to the upper end of the tracheal stent to collapse the proximal end. The patient’s dyspnea was relieved after the stent was removed
