Plain-English summary
A group of 69 dogs with severe tracheal collapse (a condition where the windpipe weakens and narrows) underwent surgery to place a special tracheal prosthesis. The dogs were divided into two groups based on the type of collapse they had: traditional and W-shaped. Those with the W-shaped collapse had more breathing difficulties before surgery but did just as well after the procedure, with a high survival rate of about 91% at three years. Most dogs recovered well, although a few experienced complications that required further treatment. Overall, the surgery proved to be a good option for these dogs.

Abstract
OBJECTIVE: To report the clinical characteristics of traditional (TTC) and W-shaped tracheal collapse (WTC) and the long-term outcomes of continuous extraluminal tracheal prosthesis (CETP) placement in dogs with grade IV tracheal collapse (TC). STUDY DESIGN: Retrospective case series. ANIMALS: A total of 69 client-owned dogs. METHODS: Medical records of dogs with grade IV TC, subclassified as TTC or WTC, treated using CETP between 2018 and 2021, were retrospectively reviewed. Clinical signs, diagnostic results, intraoperative findings, surgical complications, and clinical outcomes were analyzed. RESULTS: Of the 69 dogs, 45 had TTC and 24 had WTC. All were discharged after CETP placement. Preoperative stridor (p < .0001) and labored breathing (p = .0419) were more prevalent in patients with WTC than in those with TTC. The WTC group was 12.1 times more likely to require preoperative oxygen management than the TTC group (OR, 95% CI: 3.2-37.5). The 36-month postoperative survival rates were 75.7% and 90.9% in dogs with TTC and WTC, respectively. Postoperative laryngeal paralysis occurred in three dogs in the TTC group and two in the WTC group. Recurrent TC occurred in one dog in the TTC group and two in the WTC group. Seven of the eight dogs with postoperative complications required surgical intervention or intraluminal stent placement. CONCLUSION: Although dogs with WTC showed more severe preoperative respiratory symptoms, their postoperative outcomes were comparable with those of dogs with TTC. CLINICAL SIGNIFICANCE: CETP placement is a viable surgical treatment option for dogs with WTC, even those with severe respiratory symptoms.
