Abstract: Tracheal collapse is commonly seen in small breed dogs and is caused by a progressive weakening of the tracheal rings. A 5 year-old male Yorkshire terrier (weighing 1.97 kg) was presented Veterinary Teaching Hospital at Kangwon National University (S. Korea) with goose honking cough and cyanosis. On the radiographical and endoscopical examination, trachea was collapsed from the mid of cervical trachea to the mid of thoracic trachea. A self-expanding intraluminal stent (Zilver® 635 biliary stents, COOK, USA) was implanted to restore collapsed trachea. After implantation, the dog was medicated with cough suppressant (methylephedrine, 2 mg kg 1 BID), prednisolone (0.5 mg kg 1 BID) and cefazoline (5 mg kg 1 BID) for 2 weeks, to reduce side effects from metallic stenting. Clinical improvement was noticed right after implantation. Although mild transient dry cough lasted for a month, the dog was clinically recovered from tracheal collapse.
