Clinical signs, diagnostic results, intraoperative findings, surgical complications, and clinical outcomes were analyzed.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Of the 69 dogs, 45 had\n TTC<\/jats:styled-content>\n and 24 had\n WTC<\/jats:styled-content>\n . All were discharged after\n CETP<\/jats:styled-content>\n placement. Preoperative stridor (\n p<\/jats:italic>\n \u2009<\u2009.0001) and labored breathing (\n p<\/jats:italic>\n \u2009=\u2009.0419) were more prevalent in patients with\n WTC<\/jats:styled-content>\n than in those with\n TTC<\/jats:styled-content>\n . The\n WTC<\/jats:styled-content>\n group was 12.1 times more likely to require preoperative oxygen management than the\n TTC<\/jats:styled-content>\n group (OR, 95%\n CI:<\/jats:styled-content>\n 3.2\u201337.5). The 36\u2010month postoperative survival rates were 75.7% and 90.9% in dogs with\n TTC<\/jats:styled-content>\n and\n WTC<\/jats:styled-content>\n , respectively. Postoperative laryngeal paralysis occurred in three dogs in the\n TTC<\/jats:styled-content>\n group and two in the\n WTC<\/jats:styled-content>\n group. Recurrent\n TC<\/jats:styled-content>\n occurred in one dog in the\n TTC<\/jats:styled-content>\n group and two in the\n WTC<\/jats:styled-content>\n group. Seven of the eight dogs with postoperative complications required surgical intervention or intraluminal stent placement.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n Although dogs with WTC showed more severe preoperative respiratory symptoms, their postoperative outcomes were comparable with those of dogs with TTC.<\/jats:p>\n <\/jats:sec>\n \n Clinical significance<\/jats:title>\n CETP placement is a viable surgical treatment option for dogs with WTC, even those with severe respiratory symptoms.<\/jats:p>\n
