An uncommon neoplasm of the larynx, rhabdomyosarcoma, was diagnosed in a 6-year-old 14-kg neutered female Spitz. In addition to the progressive onset of expected clinical signs of the tumor (exercise intolerance, respiratory stridor, inability to bark), the dog experienced hyperthermic crisis. Laryngectomy was successful in eradicating the local neoplastic tissue; however, unusual postoperative complications developed and included acute complications of pharyngotracheal fistula and hypoparathyroidism, and long-term complications of periodic collapse of the tracheal stoma and intolerance to heat. Probable causes and successful management of these complications are described. At 22 months after laryngectomy, the dog was admitted for a solitary hepatic metastasis. While hospitalized, the dog died of apparent asphyxiation attributable to stoma collapse.
一只6岁、体重14千克的绝育雌性斯皮茨犬被诊断出患有罕见的喉部肿瘤——横纹肌肉瘤。除了肿瘤预期的临床症状逐渐出现（运动不耐受、呼吸喘鸣、无法吠叫）外，这只狗还经历了高热危机。喉切除术成功根除了局部肿瘤组织；然而，出现了不寻常的术后并发症，包括咽气管瘘和甲状旁腺功能减退的急性并发症，以及气管造口周期性塌陷和不耐热的长期并发症。本文描述了这些并发症的可能原因及成功的处理方法。喉切除术后22个月，这只狗因孤立性肝转移入院。住院期间，这只狗因造口塌陷导致明显窒息而死亡。
