【摘要】 目的评价内支架在气管恶性狭窄中的治疗作用。方法对重度的呼吸困难、喘呜的41例肿瘤患者。所用支架为Z形不锈钢自张式支架和镍钛温度记忆合金支架。在支气管镜引导下,采用经口腔、喉气管内支架留置术。结果全部病例均获得成功,没有技术上的失败。患者呼吸困难、喘鸣、呛咳等症状在支架留置后即刻改善。随访3～36个支架无移位,气管通畅。其中35例患者在气管支架置入后进行了化疗和(或)放疗。于手术后6～36月死亡31例,余10例仍在随访中。结论气管恶性狭窄的内支架成形术安全、有效,能明显提高患者的生活质量,为放疗或化疗创造条件。更多还原

【Abstract】 Objective To evaluate the treatment effect of stents in tracheal malignant stenosist. Methods 41 neoplasms cases were placed by intraluminal stents intubation. The main clinical symptoms were dyspnea,stridor and 2 cases with esophagotracheal fistula complaining of choking. Z stent and NiTi alloy stent were used. In all cases, peroral-laryngeal intubation of the stents was performed under bronchoscopic guidance. Results All stents were successfully placed without technical failure. The symptoms of dyspnea, stridor and choke were immediately relieved after finishing the stent placement procedure. After 3 - 36 months follow-up all stents remained in the original position and the tracheal pathway was patent. The radiotherapy and/or chemotherapy were performed in 35 cases after stent placement. There were 31 cases died during 6 to 36 mounths follow-up, 10 survival and still in follow-up. Conclusion Tracheal stenting is a safe and efficient method with immediate relief of symptoms and improvement of quality of life in patients suffering from malignant tracheobronchial stricture, making radiotherapy or chemotherapy possible.更多还原
