Abstract：
Tracheal AERO stent collapse is a rare complication compared to bronchial AERO stent collapse due to differences in the nitinol framework thickness. A 58-year-old man with a bulky anaplastic thyroid carcinoma was referred to our hospital due to exacerbation of tracheal stenosis despite the administration of lenvatinib. His tracheal stenosis exhibited a severe extrinsic compression pattern with a length of 8 cm. Because tracheotomy was inappropriate, we placed an 18 × 80 mm AERO stent. Five months later, he was readmitted with severe dyspnea due to collapse of the distal portion of the stent caused by tumor growth. Because stent removal was difficult, we placed an additional AERO stent (18 × 60 mm) to cover the collapsed portion. The additional stent successfully expanded the collapse and improved his dyspnea. To our knowledge, this is the first case where a tracheal AERO stent collapse due to a poor prognosis tumor was treated with the stent-in-stent method.
摘要：
由于镍钛诺框架厚度的差异，气管AERO支架塌陷是与支气管AERO支架塌陷相比的罕见并发症。尽管服用了lenvatinib，但由于气管狭窄加剧，一名58岁的甲状腺大变性癌患者被转诊到我们医院。他的气管狭窄表现出严重的外部压迫模式，长度为8厘米。因为气管切开术不合适，我们放置了18×80mmAERO支架。五个月后,由于肿瘤生长引起的支架远端塌陷，他因严重呼吸困难再次入院。因为移除支架很困难，我们额外放置了AERO支架(18×60mm)以覆盖塌陷部分.额外的支架成功地扩大了塌陷并改善了他的呼吸困难。据我们所知,这是首例因预后不良的肿瘤引起的气管AERO支架塌陷采用支架内支架法治疗的病例.
