Expandable metallic stents were successfully introduced in 7 patients, including 4 with left main bronchial stenosis caused by bronchopulmonary tuberculosis, 2 with main bronchial stenosis caused by lung cancer and one with tracheal stenosis caused by adenoid cystic carcinoma. The length of stenosis was 1.5-5 cm. The stents were 1.5-2.5 cm long with barbs, and their full expanded diameter was 1.5 cm. Balloon dilatation was performed before stenting in all cases. The stents were inserted by using a 10-12 Fr catheter. In all patients except the one with tracheal stenosis, stents were introduced under local anesthesia without any difficulties. No migration of stents occurred. After stent placement, there were no respiratory difficulties, and radionuclide lung perfusion scan and chest radiographic findings such as lung atelectasis showed marked improvement in three cases. Combined therapy of stent placement and bronchial arterial infusion chemotherapy showed marked effectiveness in one case with lung cancer. Expandable metallic stents were very useful in eliminating tracheobronchial stenosis symptoms.
7例患者成功植入可扩张金属支架，其中4例因支气管肺结核导致左主支气管狭窄，2例因肺癌导致主支气管狭窄，1例因腺样囊性癌导致气管狭窄。狭窄长度为1.5 - 5厘米。支架长1.5 - 2.5厘米，带有倒刺，完全扩张直径为1.5厘米。所有病例在支架置入前均进行了球囊扩张。使用10 - 12 Fr导管插入支架。除1例气管狭窄患者外，所有患者均在局部麻醉下顺利置入支架。未发生支架移位。支架置入后，无呼吸困难，3例患者放射性核素肺灌注扫描及胸部X线表现如肺不张等明显改善。支架置入联合支气管动脉灌注化疗对1例肺癌患者显示出显著疗效。可扩张金属支架在消除气管支气管狭窄症状方面非常有用。
