  • A 5-year-old male Pointer dog weighing 24 kg was referred because of a chronic cough. The dog was routinely vaccinated and treated monthly with medications to prevent heartworm and endoparasites. Blood analyses revealed no abnormalities. Chest radiographs showed interstitial and bronchial patterns in the caudal lung fields. Bronchoscopic imaging identified a collapse of the left bronchus with a mucopurulent discharge, indicating the onset of bronchomalacia. Computed tomography also showed bronchial collapse and a tapering angle in the left caudal bronchus. This case study describes the diagnosis of bronchomalacia in a Pointer dog with a chronic cough, and suggests that bronchoscopic examination is a valuable tool for identifying of the onset of bronchomalacia in dogs presenting with an uncontrolled cough.

  • Postpneumonectomy syndrome is a rare complication that usually occurs in younger patients within the first year after a right total lung resection. Its clinical presentations are stridor, dyspnea, and recurrent pulmonary infections. An airway obstruction secondary to the extreme mediastinal shift and ratation after a pneumonectomy is the main mechanism. It is commonly complicated with tracheobronchomalacia due to longstanding airway compression. The management modalities involve a repositioning of the mediastinum with volume expansion of the pneumonectomy site by a expandable prosthesis. however, other methods including an endobronchial stent insertion should be considered in the presence of a tracheobronchomalacia or in poor surgical candidates. Here we describe a case of postpneumonectomy syndrome complicated by a bronchomalacia, which was successfully treated with a self-expandable endobronchal stent.

  • Purpose : In adults, endoscopic tracheobronchial balloon dilatation and stenting have become valuable methods to establish and maintain an adequate airway lumen when tracheomalacia or neoplastic growth compromise the airways. But in children, only a few cases were reported due to technical problems. We report six children who were treated with stent implantation and describe the use and safety of airway stents. Methods : Six patients with severe airway obstruction were treated. We investigated the underlying medical problems, stenotic site, symptomatic improvement and complications, and the size and location of stent. Results : The median age of the six patients was 21 months. Three of them were mechanically ventilated and one had an endotracheal tube to maintain the patency of airway. Diagnoses were : congenital tracheal stenosis with or without bronchomalacia, granulation tissue formation after right upper lobectomy by bronchial carcinoid or after prolonged intubation, endobronchial tuberculosis, and airway compression by mediastinal undifferentiated sarcoma. Nitinol stents were implanted in the airway guided by bronchoscopy and fluoroscopy simultaneously. Three cases were placed in trachea, the others were in the bronchus. After stent implantation, all patients showed marked improvements of their airway obstructive symptoms. Four patients are doing well, although two expired due to underlying diseases. Four patients had granulation tissue formation around stents, but that was tolerable after removing the stent. Conclusion : We suggest that the use of expandible metallic stent implantation can offer safe therapeutic option even in extremely severe, life threatening and inoperable airway stenosis in children.
