BACKGROUND/AIM: Tracheal stenosis can cause respiratory problems in mature, small-breed dogs. This study aimed to evaluate the placement of an intratracheal titanium alloy stent to prevent tracheal stenosis in canine tracheal anastomosis.
MATERIALS AND METHODS
The self-expandable intratracheal stent was an alloy of nickel and titanium, at the same atomic ratio. Vital signs and respiratory patterns, C-reactive protein, radiography, computed tomography, and endoscopy results after intraluminal stenting were assessed for 3-5 months.
RESULTS
No dogs showed evidence of intraluminal tracheal stenosis or tracheitis in the region of stent insertion on tracheoscopy and computed tomography after tracheal stent placement. After 1-2 weeks of tracheal stent placement, all dogs resolved coughing and dyspnea signs and resumed normal activities.
CONCLUSION
The intratracheal stent showed no movement or deformation in the trachea, and had flexibility and an appropriate radial force. Therefore, titanium alloy tracheal stents are useful in stenotic operations for tracheal reconstruction.
背景/目的：气管狭窄可导致成熟小型犬出现呼吸问题。本研究旨在评估气管内钛合金支架置入术在犬气管吻合术中预防气管狭窄的效果。
材料与方法
自膨式气管内支架由镍钛按等原子比组成。在气管内支架置入后 3-5 个月，评估生命体征和呼吸模式、C 反应蛋白、影像学检查（放射学和计算机断层扫描）和气管镜检查结果。
结果
气管镜和计算机断层扫描检查均未见支架置入部位的气管腔内狭窄或气管炎症。气管内支架置入后 1-2 周，所有犬均咳嗽和呼吸困难症状消失，恢复正常活动。
结论
气管内支架在气管内无移动或变形，具有柔韧性和适当的径向力。因此，钛合金气管支架在气管重建的狭窄手术中很有用。
