  • Tracheal collapse at the thoracic inlet is described in a 4 year-old female yorkshire terrier. The initial presenting signs included coughing, dyspnea, cyanosis and collapse. Diagnosis was based upon the clinical signs, physical examination, plain radiography and fluoroscopy. The collapse was corrected by the aplication of a neumber of modified total ring prostheses (m-TRP) applied to the cervical trachea. Clinical complicatons were minimal and limited to mild, short-term coughing. The present study indicated that m-TRP were easy to apply to tracheal collapse and were able to decrese clinical signs. Therefore, m-TRP may be applied to tracheal collapse as new prostheses.

  • Tracheal collapse is a common respiratory disease in dogs. There are many ways to treat tracheal collapse, one of which is the use of an intraluminal stent. In this study, we divided 21 dogs into two groups and implant conventional stents and new nitinol stents. Comparison of two groups was based on following, feature of stent fracture, form of stent migration, clinical sign improvement, complication and prognosis. Approaching was established via C-arm under spontaneous breathing and placing a stent at the site of collapse. Using radiographic images, determine stent size accurately. For a comparison of identical condition, all intraluminal stents were placed 10 mm caudal from larynx to 10 mm cranial from carina. In this study, new nitinol stents improve the problems of conventional stents and may be effective in the treatment of tracheal collapse in small dogs.

  • A 3-month old female Holstein calf was presented with about a month history of intermittent dyspnea, exercise intolerance and cough despite antibiotic therapy. Auscultation revealed prominent inspiratory and exploratory crackles and wheezes over the causal cervical trachea which were heard equally over both side of the chest.4 modest amount of forced exercise caused severe respiratory distress with stertorous noise and occasional honkinglike cough. Pasteurella spp. was isolated on the nasal swabs and a hemogram showed mild leucocytosis with a mature neutrophilia and mild monocytosis. Lateral radiographs of the neck and thorax revealed a marked narrowing of the tracheal lumen extending from the level of the fifth cervical to the second thoracic vertebra, and the lung field was judged to be within normal limitsi except very mild peribronchial thickening. The hypertrophic non-union fractures of the first pair of ribs were noted with a well delineatedr redundant callus formations and also the completely healed fractures were found on the next seven pairs of ribs. A diagnosis of tracheal collapse was made, which is thought to be a traumatic origin.4 poor prognosis was given. The calf was euthanatized and necropsied. The tracheal rings from 19th to 41s1 were collapsed dorsoventrally. Histologically, there was no difference between the collapsed and normal areas of the tracheae except the folding mucosal layer in the collapsed area. This report details a case of tracheal collapse in a calli and the literature is reviewed.

  • Ninety-nine dogs diagnosed as tracheal collapse were reviewed for 2002-2003 year at Veterinary Medical Teaching Hospital, Seoul National University with clinical records and radiographs. Dogs were ranged in age from 1 to 15 years old (average 8.23 years old) and in weight from 1.2kg to 10.3kg (average 3.3kg). The population included 58 females (6 spayed) and 41 males (8 castrated). It is highly predominant in Yorkshire terrier (64, 64.6%) followed by Pomeranian (10, 10.1 %), Poodle and Chihuahua (8, 8.1%), Maltese (4, 4.0%), mixed breed (3, 3.0%), Cocker Spaniel and Pug (1, 1.0%). The incident rate of female dogs (59%) exhibited relatively higher than that of male dogs (41%). The most prevalent occurrence location was thoracic inlet (60%) of all and carina region (15%), intrathoracic trachea (14%) and cervical trachea (11 %) showed similar rate. Conclusively, tracheal collapse was observed in completely matured or old small breed dogs, largely Yorkshire terrier, on thoracic inlet primarily regardless of gender. These tendencies were apparently similar to previous reports.

  • The purpose of this study was to compare easiness of application of polypropylene external total ring prosthesis (PPTRP, Group A) with that of polyvinylchloride external total ring prosthesis (PVCTRP, Group B), which were used for surgical correction of tracheal collapse in dogs. PPTRP was made from 3 ml syringe and PVCTRP from the drip chamber of intravenous administration set. Prostheses of group A (n=5) and B (n=5) were placed to cervical trachea in clinically normal 10 dogs, respectively weighing between 4 kg and 6 kg. There were mild coughing and swelling in one to three dogs of both groups for 3 days after surgery. No exercise intolerance was observed in both groups after surgery. There were no different results of clinical signs and radiographic views after surgery between group A and group B. The time (mean${\pm}$SD) to make total ring prosthesis, group A took $23.2{\pm}1.9$ minutes which was remarkably longer than that $(4.6{\pm}0.3)$ of group B. Also, the time to place around trachea, group A required $61.8{\pm}8.8$ minutes and group B $38.4{\pm}8.0$ minutes. Conclusionly, PVCTRP was timesaving and easier to make, fix, and suture than those of PPTRP. PVCTRP may be used alternatively to PPTRP for the tracheal collapse to treat in dogs.

  • Three dogs were presented with signs of recurrence of coughing, dyspnea and difficulty of barking after endotracheal stent placement. On the basis of history taking, physical examination, laboratory tests and radiography, complications of endotracheal stent were suspected. Dog 1 had unfitted stent diameter (stent diameter is larger than tracheal diameter) and getting disentangled of proximal tracheal stent wire. Dog 2 was suspected a foreign body reaction. Dog 3 had the migration of stent caudally. Based on these cases, the veterinarian should accurately evaluate the indicated patients before endotracheal stent and has to select the appropriate stent (diameter, length and location) to prevent complications after endotracheal stent and concern the regular follow-ups to assure proper endotracheal stent placement.

  • A 15 years old castrated male Pug dog was referred with chief complaint of cough, described as a goose honk. He was diagnosed into of tracheal collapse by clinical signs and radiography. He was received by injection- AP with butorphanol (0.15 mg/kg, SID) at BL13, LU01, LU05, LU06, LU07, LU09 and CV22 for 10 days, and he was also received by injection-AP with butorphanol (0.40 mg/kg, SID) at BL13, LU01 and CV22 for 9 days. The patient was given with Sochungryong-Tang (0.5 g/head, TID) for 7 days, and he was additionally given with Sojagangki-Tang (1 ml/kg, TID) for 12 days. Cough was not detected at all, and tracheal diameter was more increased than that of session 1 on radiograph at session 19. Cough was not detected at all and tracheal diameter at follow-up study of three month later was more dilated than that of session 19. In conclusion, the present patient was a case with canine tracheal collapse which showed favorable therapeutic response by injection-AP with butorphanol combined by administration of herbal medicine.

  • Relapsing polychondritis is a rare disesase involving any cartilaginous structure of entire body and is characterized by recurrent episode of inflammation and degeneration of cartilage and most commonly involve ear, nose, larynx, trachea, ribs, Eustachian tube, etc. Its signs and symptoms are recurrent swelling of auricle, saddle nose deformity, polyarthralgia, hoarseness and dyspnea, audiovestibular disturbance and cardiovascular abnormality, etc. Characteristic histologic findings are loss of normal basophilic staining of cartilage, perichondrial inflammatory infiltration with plamsa cells, lymphocytes and neutrophils, and finality, destruction of cartilage and replacement with scar tissue. Our case had saddle nose deformity, arthralgia, tracheal collapse, hearig loss and positive histologic finding but no auricular perichnodritis. Her major problem was airway. obstruction due to tracheal collapse. This case was diagnosed with relapsing polychondritis according to the Damiani's criteria. This case indicates that any patients complaining of airway obstruction have to be examined systemically.

  • Objectives: Endoscopic airway dilatation and stenting has been developed to treat the airway stenosis without potential morbidities of open surgery. We report the clinical results of endoscopic airway dilatation with silicone stenting in patients with posttuberculous bronchial stenosis(PTBS) and with severe main tracheal stenosis who have poor general conditions Methods : A prospective observation study of five patients, who have undergone endoscopic airway dilatation and silicone stenting between Feb 2007 and Feb 2009. A total of twelve patients were treated with endoscopic airway dilatation, among them 5 patients were included in this study. three patients were treated with newly designed silicone stent (Natural stent: TNO Co., Seoul, South Korea) because of poor surgical conditions and longer stenotic segment Results: 3 patients were grade III PTBS, and the other 2 patients were grade IV post tracheotomy main tracheal stenosis. One patient of PTBS were treated with silicone stent following endoscopic dilatation because of longer stenotic segment. Two patients of main tracheal stenosis patients were treated with silicone stent because of tracheal lumen collapse. There was no severe postoperative complications except mild granulation tissue formations Conclusions : Endoscopic dilatation including silicone stenting could be a useful method for treating patients with PTBS, and for main tracheal stenosis patients with poor general surgical conditions
