Background: Stenting is an effective treatment option for tracheal collapse in dogs. Cross-braided tracheal stents are currently the norm in veterinary medicine, but cross-and-hook braided stents have recently been adopted in human medicine. We examined whether stents manufactured using this novel braiding technique provided additional advantages for the treatment of tracheal collapse in dogs. Objectives: To evaluate the outcomes of cross-and-hook braided stent implantation in the treatment of tracheal collapse in dogs. Methods: The medical records of 22 client-owned dogs that underwent luminal placement of cross-and-hook braided Fauna Stents for the treatment of tracheal collapse between January 2018 and July 2021 were examined and data on canine signalment, clinical signs, diagnostic test results, surgical outcomes, and postoperative complications were retrieved and analyzed statistically. Results: Twenty-six stents were surgically implanted, with 20 dogs (90.9%) receiving one stent and the remaining two (9.1%) receiving two or more stents. All dogs survived the procedure. The median survival time at a median follow-up of 990 days was 879 days. At the final follow-up examination, loss or mild improvement of cough was observed in all dogs. Conclusions: Compared with conventional lumen stents, the cross-and-hook braided Fauna Stent offered a higher survival rate and improved clinical symptoms in all patients. The results of this study suggest that the Fauna Stent may be a promising treatment option for dogs with tracheal collapse.

Tracheal Stenosis after Tracheostomy Treated Successfully with Papillotome Electrocautery A 39-year-old woman presented with symptoms of dyspnea. Ten years previously, she had received a tracheostomy because of the decision to not continue taking an anticonvulsant drug. Presently, chest computed tomography showed diffuse stenosis and focal web at the cervical trachea. We performed bronchoscopy and found a two-thirds reduction of the upper trachea due to the web-like fibrotic stenosis. Papillotome electrocautery removed the stenotic lesion. Endobronchial electrocautery is a valuable tool with potential for therapy of an endobronchial obstructing airway lesion. We report this case to introduce the successful treatment with papillotome electrocautery.

We report a rare case of primary tracheal malignent melanoma documented by careful clinical examination. Differentiation between primary and metastatic malignant melanoma is very difficult We conclude that this tracheal tumor is a primary malignant melanoma based on characteristic pathologic features and the exclusion of the possibility of spontaneous regression of the primary site by patient's history and physical examination.

Obstructive Fibrinous Tracheal Pseudomenbrane (OFTP) is a rarely known but potentially fatal complication of endotracheal intubation. Sudden respiratory failure shortly after extubation is not infrequent in the ICU. However, these cases are commonly diagnosed as laryngospasm, retention of secretion or laryngeal edema. A 68-year-old woman presented with a 6-day history of progressive dyspnea. She had undergone invasive ventilator care for 24 hours. The patient was discharged from the hospital with improvement after having an extubation. However, after 3 days she revisited the emergency department with progressive dyspnea. The patient was diagnosed with OFTP from the results of chest CT and bronchoscopy. This is the first case studied in detail using CT images, pulmonary function test, and bronchoscopy.

We have experienced a case of lung injury caused by accidental inhalation of ammonia gas in a 34 year-old-man. By the explosion of ammonia tank in a refrigerator boat he inhaled ammonia gas. Several minutes later, he suffered from severe dyspnea and visual loss. On arrival at emergency room, analysis of arterial blood gas revealed severe hypoxemia and his chest film showed bilateral pulmonary infiltrates. Under the impression of adult respiratory distress syndrome, mechanical ventilator was applied to the patient. After recovery from ARDS and tracheal edema, he complained of some hemoptysis and productive sputum during the admission. So we checked bronchoscopy and bronchograpy which showed tracheal bullae just above carina and tubular bronchiectatic change in the right lower lobe. We report a case of lung injuries-ARDS, tracheal bullae, and bronchiectasis-caused by inhalation of ammonia gas with the review of the relevant literatures.

The trachea is defined as the airway from the inferior border of the cricoid cartilage to the top of the carinal spur. This paper would confirm the normal tracheal length of Korean adults through the actual measurement using the fiberoptic bronchoscopy. The subjects of this study were 25 patients, 13 males and 12 females between the age of 20 to 69 without abnormality on the neck, trachea, mediastinum and lung pharenchyme on the preoperative chest X-ray, who received the operations from the period of July to September, 1994. For those patients who had heart diseases, the cardiothoracic ratio was below 50%. The measurement was performed on the patients with endotracheal intubation under the general anesthesia in supine and neutral position. The tracheal length was calculated by the difference between the length from the tip of the endotracheal tube [E-tube to carina and to the needle which was inserted into the E-tube at the lower border of the palpated cricoid cartilage, by inserting the broncoscopy through the E-tube. The result was as follow : 1 The measured tracheal length for men was 11.8 0.2 cm[mean standard deviation and women was 10.5 0.3 cm, and that was longer than this [p<0.01 . The average was 11.2 1.0 cm and the standard error was 0.20 cm. 2 According to the correlation between the tracheal length to weight, height[Ht , age, and body surface area[BSA respectively, the Ht [p=0.003 , age [p=0.055 , and the BSA[p=0.017 were significant, while weight was not [p=0.314 . 3 From the regression analysis of the tracheal length[T.L. to the Ht, Age, and the BSA which were significant, the following equation was derived.i Ht : T.L.= -1.29 + 0.076 x Ht [P=0.003 ii Age: T.L.= 10.04 + 0.028 x Age [P=0.055 iii BSA : T.L.= 5.60 + 3.48 x BSA [P=0.017 iv In multi-regression : T.L. = -4.15 + 0.034 x Age + 0.085 x Ht [P=0.0002]

배 경 : 동물 모델을 이용하여 일정한 수준의 상기도 협착을 일으킬 수 있다면 이에 대한 임상교육에도 도움이 되며 새로운 진단법이나 치료법의 개발을 보다 쉽게 할 수 있을 것이다. 저자들은 한국산 잡견을 이용하여 Nd-YAG Laser 소작술로 기관 협착을 일정하게 유도하는데 성공하여, 이에 대해 기술하고자 본 연구를 시행하였다. 방 법 : 체중 22kg 정도의 한국산 잡견 6마리를 전신마취 시킨 후, Nd-YAG 레이저를 이용하여 4개의 기관 연골환의 전방부 180도를 $8946{\pm}2484$ Joule로 소작 하였다. 실험 동물은 매 1주마다 4주 동안 기관지내시경으로 기관 협착 정도를 관찰하였고, 병리학적 검사를 같이 시행하였다. 결 과 : 시판 협착은 레이저 소작 2주 후부터 시작되어 3주후까지 빠른 속도로 진행되었으며, 소작 4주 후에 가장 심한 양상을 보였다, 모든 실험 동물은 제 3주가 지나 심한 호흡곤란과 천명음, 식욕부진 및 체중 감소를 보였고, 이중 2마리는 호흡부전으로 4주가 되기 전에 사망하였다. 병리 육안소견상 소작 부위의 기관 연골이 소설되고 섬유조직으로 치환되어 외경도 감소되어 있었고, 현미경 소견에서 연골이 소실되고 섬유화 조직이 협착을 일으켜 내경이 감소된 모습을 확인 할 수 있었다. 결 론 : 이러한 기도 협착 동물 모델은 향후 기도 협착의 이해, 교육, 새로운 진단 및 치료법의 개발에 도움을 줄 것으로 사료된다.

비관통성 흉부손상에 의한 기관-기관지 파열의 높은 사망률과 이환율은 조기 진단과 수술로 이를 낮출 수 있으므로 초기 임상증상과 단순흉부방사선상 기관-기관지 파열이 의심되는 소견이 있으면 바로 기관지경검사로 기관-기관지 파열을 진단하고 적절한 치료를 해야한다. 저자들은 교통사고후 비관통성 흉부손상을 받고 호흡곤란을 주소로 내원한 환자에서 기관지경검사로 기관 파열을 조기 진단하여 수술적 치료로 회복시킨 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다.
