To evaluate the application of Ni-Ti shape memory alloy stent for treating tracheal stricture, including its indications and complications.
Forty-three patients clinical data were analyzed, among them, 15 suffered from tumor; 7 trauma; 4 granulation; 1 Wegener's granuloma, 2 rhinoscleroma, 1 without clear diagnosis; 7 were relapsing polychondritis; 1 were respiratory amyloidosis; 4 were tracheobronchial tuberculosis, 5 were tracheobronchomalacia. The stricture degree: Level I: 15 patients, Level II:24 patients, Level III:4 patients. The location of stricture in 5 patients extended to the subglottis area. All patients had tracheal stricture and accepted the treatment with Ni-Ti shape memory alloy stent.
Forty-two patients breathed freely after the operation, 1 patient died after surgery. The tracheostoma in 18 patients was closed 34 days after operation. Among the remaining 8 patients with tracheostoma:3 patients left hospital with tracheal cannula; 1 patient died,2 patients were found stent shifted and no evident breath improving; 2 patients were found granulation and had secondary operation with laser.
Ni-Ti shape memory alloy stent can expand the tracheal stricture quickly and thus improve the breath effectively, which is minimally invasive and simple. It can be used as a method in the treatment of tracheal stricture.
评估镍钛形状记忆合金支架在治疗气管狭窄中的应用，包括其适应证和并发症。
分析43例患者的临床资料，其中，15例患有肿瘤；7例有创伤；4例有肉芽组织；1例为韦格纳肉芽肿，2例为鼻硬结病，1例诊断不明确；7例为复发性多软骨炎；1例为呼吸道淀粉样变性；4例为气管支气管结核，5例为气管软化症。狭窄程度：Ⅰ级：15例患者，Ⅱ级：24例患者，Ⅲ级：4例患者。5例患者狭窄部位延伸至声门下区。所有患者均有气管狭窄并接受了镍钛形状记忆合金支架治疗。
42例患者术后呼吸通畅，1例患者术后死亡。18例患者的气管造口在术后34天闭合。其余8例有气管造口的患者中：3例带气管套管出院；1例死亡，2例发现支架移位且呼吸改善不明显；2例发现有肉芽组织并接受了激光二次手术。
镍钛形状记忆合金支架能迅速扩张气管狭窄，从而有效改善呼吸，具有微创、操作简单的特点。可作为治疗气管狭窄的一种方法。
