| 目的 探讨64层螺旋CT在良性气管狭窄支架治疗中的应用价值。方法 14例气管狭窄患者在支架置入术前、术后1个月、并发症发生时及支架取出后行64层螺旋CT和支气管镜检查,回顾分析其MSCT及支气管镜表现。结果 MSCT显示了全部14例气管狭窄,其中上段7例,中段5例,下段1例,上段和中段两处狭窄1例,狭窄段长度12.9~41.9 mm,平均(28.09±7.99)mm,狭窄段直径1.5~8.2 mm,平均(5.68±2.22)mm,置入支架后,狭窄段直径11.6~16.4 mm,平均(13.69±1.25)mm,支架取出后狭窄段直径10.2~15.6 mm,平均(11.96±1.44)mm。支架相关并发症:全部14例均有肉芽组织增生和黏液滞留,2例发生支架移位。支气管镜显示了全部14例气管狭窄,气管黏膜充血、支架表面滞留液和气管壁、肉芽组织的动态变化,其中5例先端未能通过狭窄段而不能全面观察病变。结论 MSCT在良性气管狭窄治疗中具有重要的临床应用价值,可作为首选影像学检查方法。 |

| Objective To observe the application value of 64-slice CT in the treatment of benign tracheal stenosis with airway stent implantation. Methods All 14 patients with tracheal stenosis underwent 64-slice CT and bronchoscopy before stent implantation, one month after stent implantation, as well as on the occurrence of stent-related complications and after stent removal. MSCT and bronchoscopy findings of 14 patients were analyzed retrospectively. Results Tracheal stenosis of all 14 patients were showed with MSCT, stenosis was located in superior segment in 7 patients, middle segment in 5 patients, inferior segment in 1 patient, both superior segment and middle segment in 1 patient. The length of tracheal stenosis was 12.9—41.9 mm, mean (28.09±7.99)mm. The diameter of tracheal stenosis was 1.5—8.2 mm, mean (5.68±2.22)mm. The diameter of tracheal stenosis was 11.6—16.4 mm, mean (13.69±1.25)mm after stent implantation, whereas 10.2—15.6 mm, mean (11.96±1.44)mm after stent retrieval. Stent-related complications included granulation tissue and mucus retention in all 14 patients, and stent migration in 2 patients. All tracheal stenosis, hyperemia of the tracheal mucous membrane, mucus on the stent surface and motion of the tubal wall and granulation tissue were observed with bronchoscopy, among them, 5 patients were not observed completely because the distal end of the bronchoscopy failed to pass through the tracheal stenosis segment. Conclusion MSCT has great clinical value in airway stent implantation of benign tracheal stenosis, and can be used as the first choice of imaging examination. |
