Chapter 159 The combination of surgical risk and the inability of the ring procedure to treat intrathoracic collapse adequately led to the evaluation of human-intended intraluminal tracheal stents for the treatment of affected dogs. A number of stents have been previously evaluated in the canine trachea, including both balloon-expandable (Palmaz) stents, and self-expanding stents (stainless steel, laser-cut nickel-titanium [nitinol], and knitted nitinol). Clinical improvement has been reported in 75% to 90% of animals treated with intraluminal stainless steel, self-expanding stents (Moritz et al, 2004), and long-term improvement was noted in 10 of 12 dogs treated with nitinol self-expanding metallic stents (Sura and Krahwinkel, 2008). Immediate complications were typically minor; late complications included stent shortening, development of excessive inflammatory tissue, progressive tracheal collapse, and stent fracture.
