A 57-year-old man was admitted because of dysphagia. Two year earlier, endoscopic ND-YAG laser treatment had been performed for squamous cell carcinoma of the tracheal carina. The esophagus was compressed and narrowed by invasion of lung cancer. After ballooning, under endoscopic and fluoroscopic control, a self-expanding nitinol stent (SENS, Ultraflex, Microvasive) was implanted in the esophagus. Immediately after esophageal prosthesis implantation, severe dyspnea and stridor developed because of tumor strictures in the left main bronchus. Under fluoroscopic and guide-wire control, SENS (Accuflex, Microvasive) was implanted in the tracheobronchial tree. Dyspnea, dysphagia and stridor were markedly improved after placement of two nitinol stents. Highly flexible, knitted, self-expanding nitinol stent is made of a nickel titanium alloy. Although the implantation of SENS in tracheobronchial stenosis has not previously been reported, it should be useful for prevention of airway obstruction.
一名57岁男性因吞咽困难入院。两年前，曾对气管隆突鳞状细胞癌行内镜下钕钇铝石榴石激光治疗。食管癌侵犯导致食管受压狭窄。在胃镜和荧光镜控制下进行球囊扩张后，将自膨式镍钛合金支架（SENS，Ultraflex，Microvasive公司）植入食管。食管假体植入后即刻，因左主支气管肿瘤狭窄出现严重呼吸困难和喘鸣。在荧光镜和导丝控制下，将SENS（Accuflex，Microvasive公司）植入气管支气管树。植入两个镍钛合金支架后，呼吸困难、吞咽困难和喘鸣明显改善。高柔韧性、编织型、自膨式镍钛合金支架由镍钛合金制成。虽然此前尚未报道SENS用于气管支气管狭窄的植入情况，但它应有助于预防气道阻塞。
