To determine factors associated with long-term outcome in dogs with tracheal collapse treated with extraluminal polypropylene C-shaped stents.
Retrospective case series.
90 dogs.
Medical records of dogs with surgically treated tracheal collapse were reviewed. Follow-up was obtained either by recheck at the veterinary teaching hospital only (n = 10) or by telephone interviews with referring veterinarians and owners (n = 35), referring veterinarians alone (n = 23), or owners alone (n = 16). The chi 2 test was used to determine which factors were associated with long-term outcome.
11 breeds were represented. Yorkshire Terriers, Poodles, and Pomeranians were most common. Median age at the time of surgery was 6.8 years. Median weight was 2.9 kg. Severity of collapse ranged from grade II to grade IV. Dogs < 6 years old had more severe collapse than did dogs > or = 6 years old. Dogs > or = years old had more postoperative complications and a poorer longterm outcome than did dogs < 6 years old. 17 dogs required permanent tracheostomy, 10 within 24 hours after surgery.
Surgical placement of extraluminal polypropylene C-shaped stents was an effective method of attenuating clinical signs of tracheal collapse. Dogs < 6 years old had more severe tracheal collapse but did better after surgery than did dogs > or = 6 years old.
确定接受腔内聚丙烯C形支架治疗的气管塌陷犬长期预后的相关因素。
回顾性病例系列研究。
90只犬。
回顾接受手术治疗气管塌陷犬的病历。通过仅在兽医教学医院复查（n = 10）或通过与转诊兽医和犬主电话访谈（n = 35）、仅与转诊兽医访谈（n = 23）或仅与犬主访谈（n = 16）来进行随访。采用卡方检验确定哪些因素与长期预后相关。
涉及11个品种。约克夏梗犬、贵宾犬和博美犬最为常见。手术时的中位年龄为6.8岁。中位体重为2.9千克。塌陷严重程度从II级到IV级不等。年龄<6岁的犬比年龄≥6岁的犬塌陷更严重。年龄≥6岁的犬比年龄<6岁的犬术后并发症更多且长期预后更差。17只犬需要永久性气管造口术，其中10只在术后24小时内。
腔内聚丙烯C形支架的手术放置是减轻气管塌陷临床症状的有效方法。年龄<6岁的犬气管塌陷更严重，但术后比年龄≥6岁的犬恢复更好。
