An expandable metal stent inserted via a long term tracheostomy successfully relieved life threatening respiratory obstruction due to benign tracheal stenosis. Later the patient's tracheostomy suction catheter became stuck on the stent and dislodged it. The stent was removed electively, without damaging the trachea, with a rigid biopsy forceps.
通过长期气管造口术插入的可扩张金属支架成功缓解了因良性气管狭窄导致的危及生命的呼吸阻塞。后来,患者的气管造口吸引导管卡在支架上并使其移位。使用刚性活检钳选择性地取出支架,未损伤气管。
