全身麻醉下气管支架植入术治疗恶性气管狭窄

目的评价全身麻醉下气管支架植入术治疗恶性气管狭窄的疗效。方法选择因恶性肿瘤致气管狭窄、中、重度呼吸困难患者17例，行全身麻醉及气管插管，于DSA监视下经气管套管植入镍钛记忆合金支架。结果全部病例均成功植入支架，呼吸困难症状立即得到改善。随访3～24个月，支架无移位，气管通畅，患者无明显疼痛及异物感。结论全身麻醉下气管支架植入术治疗恶性气管狭窄安全、快捷、有效，患者痛苦小，可为后续治疗提供条件。

Under general anesthesia endotracheal stenting for the treatment of malignant tracheal stenosis

Objective To assess the curative effect of under general anesthesia endotracheal stenting for the treatment of malignant tracheal stenosis. Methods Seventeen patients with malignant tumors and moderate and severe dyspnea caused by tracheal stenosis were collected and underwent endotracheal stenting under general anesthesia. Nickel-titanium shape memory alloy stents were implanted through tracheal tube to the stenosis under DSA fluoroscopy. Results Technical success was achieved in all patients. The dyspnea was improved immediately after stent placement. Following-up for 3-24 months showed that there was no stent displacement, no obstruction of the airway, nor obvious pain and foreign body sensation in all cases. Conclusion Under general anesthesia tracheal stent implantation is safe, fast, effective and little pain for the treatment of malignant tracheal stenosis, which contributes to subsequent treatment.
