Preliminary Study for a Newly Designed Silicone Stent and Delivery System for Canine Obstructive Tracheal Disease

초록

The goal of this study was to prove the possibility of using silicone stents broadly used for human medicine in canine obstructive tracheal disease. A silicone stem anatomically designed for canine trachea was tested on 5 beagle dogs for 8 weeks. The stem was carefully inserted using a newly developed delivery device under fluoroscopic guidance. There were no technical difficulties in placing the stent during the procedure. Previously reported complications of airway stenting such as stent migration or granulation tissue formation did not occur in any of the cases. In addition, removal of the stent was as simple as inserting it, and complications were absent. The stein introduced in this study could possibly be applied to various canine obstructive tracheal diseases.
