Long‐term outcomes of dogs with W‐shaped or traditional tracheal collapse treated with a continuous extraluminal tracheal prosthesis: A retrospective study
🔍 Key Findings
- Dogs with W-shaped tracheal collapse (WTC) had significantly more stridor and labored breathing preoperatively than those with traditional collapse (TTC) (p < .0001 and p = .0419).
- WTC dogs were 12.1× more likely to require preoperative oxygen support than TTC dogs.
- All dogs (TTC and WTC) survived to discharge after CETP placement; no intraoperative deaths occurred.
- Postoperative laryngeal paralysis occurred in 5 dogs (7.2%), with similar rates between TTC and WTC groups.
- Recurrent tracheal collapse occurred in 3 dogs (1 TTC, 2 WTC), all requiring additional stenting.
- 36-month survival was 75.7% (TTC) and 90.9% (WTC), not statistically different.
- Multivariate analysis showed Yorkshire Terriers (HR = 19.3) and older age (HR = 1.35 per year) were significantly associated with reduced survival.
- CETP was safe and effective for WTC, despite more severe preoperative signs, offering a viable alternative to stenting.
