Airway stenting provides an important treatment option for patients with proximal tracheal stenosis. However, the risk of migration remains a major challenging problem. In our report we describe the internal fixation of SEMS in 3 patients with proximal tracheal stenosis due to variable causes. The fixation was performed in different situations including: prophylaxis to prevent the stent migration, fixation due to displacement of the stent during insertion and finally internal fixation of migrated tracheal stent.

Other advantages of Arista AH include simplicity of use, low cost, and widespread availability in hospital operating rooms.Recent publications have described the use of Arista AH powder for endoscopic sinus surgery, 7 neurosurgery, 8 prostatectomy with lymphadenectomy 9 all resulting in reduced bleeding. To our knowledge, this is the first case of the endobronchial use of Arista AH. In this case, it was a life-saving measure after exhaustion of the other more traditional therapies. The use of this hemostatic proved to be useful and merits further consideration in the treatment of refractory life-threatening hemoptysis.
