Results of using intratracheal stents with different thickness of nitinol thread in tracheal collapse

Tracheal collapse syndrome in dogs is a chronic progressive respiratory disease that most often occurs in adult small breed dogs and the most effective way to treat tracheal collapse in dogs is endoscopic surgery with the placement of a nitinol stent. In this regard, the search for a stent that can withstand various tissue loads and the controlled duration of its working states seems to be a promising direction in the treatment of tracheal collapse. As a result of the comparison, a smaller number of postoperative complications were found when using stents with a smaller nitinol thread thickness in the short term due to a more flexible design, but in the long term, relapse of the disease and complications are also likely. But with existing methods of drug support, these complications can be stopped. The difference between tracheal stents with different nitinol thread thickness is explained by the quality of the materials used, as well as the difference in ensuring the optimal load of the implanted material.
