To review the removal of Y-shaped airway self-expanding covered metallic stents using the interventional technique under fluoroscopy.
The clinical data of 33 patients who underwent removal of Y-shaped airway self-expanding covered metallic stents from March 2011 to August 2019 were analysed retrospectively.
A total of 35 Y-shaped stents were removed. The average indwelling duration of the tracheal stents was 101.7 ± 105.4 days. Four cases were removed via the conventional method (grasping the upper tip of the stent to collapse and adduct the proximal end of the stent), whereas 31 cases were removed using the reversal method (grasping the distal end of the stent to invert and strip out the stent). The duration of stent removal was 24.3 ± 12.4 minutes (median time, 20 minutes).
The interventional radiology technique is a feasible, safe, and effective method for removing Y-shaped airway self-expanding covered metallic stents, and can be considered for use in the clinical setting.
回顾在透视下使用介入技术取出 Y 型气道自膨式覆膜金属支架。
回顾性分析 2011 年 3 月至 2019 年 8 月 33 例接受 Y 型气道自膨式覆膜金属支架取出的患者的临床资料。
共取出 35 个 Y 型支架，气管支架平均留置时间为 101.7±105.4 天。4 例采用常规方法（抓住支架的上尖端使支架塌陷并使近端靠拢）取出，31 例采用反转方法（抓住支架的远端使支架翻转并将其取出）。支架取出时间为 24.3±12.4 分钟（中位数时间为 20 分钟）。
介入放射学技术是一种可行、安全、有效的取出 Y 型气道自膨式覆膜金属支架的方法，可在临床中应用。
