To evaluate the technical feasibility and safety of covered airway stent placement for malignant tracheobronchial strictures in patients with an endotracheal tube.
Data regarding retrievable, expandable, metal stent placement under fluoroscopic guidance in 20 patients with an endotracheal tube inserted for malignant tracheobronchial strictures were retrospectively analysed. The clinical effectiveness was assessed using the following variables: technical and clinical success; procedure and stent-related complications; and duration of intubation following stent placement.
Stent placement was technically successful in all 20 patients (100%), and with 19 of the 20 patients (95%) showing symptomatic improvement within 5 days. The endotracheal tube could be removed during (n=7) or after (n=12) stent placement, and the mean duration of intubation following stent placement was 1.4 days (range 0-3 days). One patient could not have his endotracheal tube removed and he died 9 days following stent placement in an intubated state. There were no procedure-related complications. Stent-related complications in three patients included partial (n=2) and complete (n=1) stent migration, all of which were managed with placement of a second stent (n=2) or stent removal and placement of a second stent (n=1).
Covered airway stent placement under fluoroscopic guidance in patients with an endotracheal tube inserted for malignant tracheobronchial strictures, is both technically feasible and safe.
评估在气管插管患者中置入覆膜气道支架治疗恶性气管支气管狭窄的技术可行性和安全性。
回顾性分析20例因恶性气管支气管狭窄而插入气管插管的患者在透视引导下置入可回收、可扩张金属支架的数据。使用以下变量评估临床疗效：技术和临床成功率；操作及支架相关并发症；支架置入后的插管持续时间。
20例患者支架置入技术均成功（100%），20例中有19例（95%）在5天内症状改善。气管插管可在支架置入期间（n = 7）或之后（n = 12）拔除，支架置入后插管的平均持续时间为1.4天（范围0 - 3天）。1例患者气管插管无法拔除，在插管状态下支架置入9天后死亡。无操作相关并发症。3例患者的支架相关并发症包括部分（n = 2）和完全（n = 1）支架移位，所有这些均通过置入第二个支架（n = 2）或取出并重新置入第二个支架（n = 1）进行处理。
在因恶性气管支气管狭窄而插入气管插管的患者中，透视引导下置入覆膜气道支架在技术上可行且安全。
