Mediastinitis is a rare complication of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). Recent reports of infectious complications following EBUS-TBNA involved oropharyngeal bacteria. Here, we report 2 unusual cases of post-EBUS-TBNA mediastinitis involving Streptococcus pneumoniae and Pseudomonas aeruginosa, which were likely the result of direct inoculation of the organisms at the time of transbronchial needle aspiration. The first case was successfully treated with computed tomography-guided drainage and antibiotics, whereas the second case had >50% distal tracheal obstruction and near total occlusion of the left main stem bronchus, requiring rigid bronchoscopy, stent placement, debulking, and antibiotics...

Posttracheostomy tracheal stenosis is a rare complication of prolonged tracheal intubation. Treatment modalities that may be used include surgical resection and anastomosis, endoscopic tracheal dilation, laser resection, and tracheal stenting. We describe a novel salvage modality for dilation of a symptomatic tracheal stenosis using a percutaneous tracheostomy dilator wherein rigid bronchoscopic dilation was not feasible and balloon tracheal dilation had failed.

Severe and critical central airway obstruction causing impaired ventilation and/or oxygenation can impose tremendous challenges on the interventional pulmonologist. Near total airway obstruction can rapidly evolve into potentially fatal complete airway occlusion during bronchoscopic airway manipulation under moderate sedation; as well as during the induction of the general anesthesia. Although there are currently interventional pulmonary procedures available to tackle the critical airway obstruction in extreme situations, cardio-pulmonary bypass should be considered prior to the intervention to maintain the adequate gas exchange during the procedure...

OBJECTIVES: Evaluation of complex, acquired, non-malignant tracheo/broncho-oesophageal fistulas (TEF) repaired by extrathoracic pedicled muscle flaps that were, in addition to their interposition between the airways and the gastro-intestinal tract, patched into gastro-intestinal or airway defects if primary closure seemed risky. METHODS: A single institution experience of patients treated between 2003 and 2015. Twenty-two patients required TEF repair following oesophageal surgery (18), Boerhaave syndrome (1), chemotherapy for mediastinal lymphoma (1), carinal resection and irradiation (1) and laryngectomy (1); 64% of them underwent prior radio- or chemotherapy and 50% prior airway or oesophageal stenting...

BACKGROUND: Airway transplantation remains a major challenge in thoracic surgery. Based on our previous laboratory work, we developed the techniques required to bioengineer a tracheal substitute in vivo using cryopreserved aortic allografts as biological matrices (Replacement of the Airways and/or the Pulmonary Vessels Using a Cryopreserved Arterial Allograft [TRACHEOBRONCART] Study, NCT01331863). We present here 2 patients who had a definitive tracheostomy for complex laryngotracheal stenoses refractory to conventional therapy...

The trachea has a complex anatomy to fulfill its tasks. Its unique fibro-cartilaginous structure maintains an open conduit during respiration, and provides vertical elasticity for deglutition, mobility of the neck and speech. Blood vessels pierce the intercartilaginous ligaments to perfuse the ciliated epithelium, which ensures effective mucociliary clearance. Removal of a tracheal segment affected by benign or malignant disease requires airtight restoration of the continuity of the tube. When direct approximation of both tracheal ends is no longer feasible, a reconstruction is needed...

Endobronchial stent placement is a novel therapy for treatment of iatrogenic tracheal tears. A review of the available literature shows surgery and long-term intubation being the established treatment strategy. We describe the case of a 64-year-old woman with a tracheal rupture following endotracheal intubation for routine surgery. Pneumo-mediastinum and chest pain were the predominant symptoms. She was treated with a covered self-expandable metal stent that closed the tear and led to immediate symptom relief...

BACKGROUND: The incidence of caudal stent migration in high tracheal stenting is 13-21% and is common with silicone stents. This can lead to major problems, including emergency repeat procedures. Several antimigration methods are described, but have limitations in terms of their success rate, availability, cost or ease of the procedure. OBJECTIVES: We describe an innovative method of stent migration prevention using a simple percutaneous anchoring "hitch stitch", validated in a large series...

Objective: To study the effect of self-expanding bare metal stents on the trachea of dogs, and therefore to provide useful information for choice of airway stents by interventional physicians. Methods: In this experiment, 8 beagles were randomly divided into 4 groups. Four self-expanding metal stents of different diameters (16, 18, 20 and 22 mm, respectively) were placed in the trachea of these beagles for 3 months and their impacts on normal trachea were observed. Results: In the 16 mm stent group (stent-to-airway diameter ratio 103%), good epithelialization was observed and the tracheal structure had no significant damage...

The convergence of additive manufacturing and shape-morphing materials is promising for the advancement of personalized medical devices. The capability to transform 3D objects from one shape to another, right off the print bed, is known as 4D printing. Shape memory thermosets can be tailored to have a range of thermomechanical properties favorable to medical devices, but processing them is a challenge because they are insoluble and do not flow at any temperature. This study presents here a strategy to capitalize on a series of medical imaging modalities to construct a printable shape memory endoluminal device, exemplified by a tracheal stent...

Non-malignant and malignant obstruction of the tracheal airway causes significant morbidity and mortality. With increased use of artificial airways, benign and iatrogenic complications are increasing. A tracheal stenosis that is less than 5 cm in length can be resected with end-to-end anastomosis. Longer tracheal lesions can be treated in a palliative way by placement of a stent to secure airway lumen patency. The management of tracheal defects is an evolving field. Tracheal transplantation and tracheal regeneration may provide major treatment advances to cases with long-segment tracheal involvement...

BACKGROUND: Bare metal stents may cause complications like fibrous encapsulation, granulation and tracheal stenosis. We investigated the behaviour of three commercially available stents in vivo (rabbits) and in vitro (coculture of those stents with epithelial and fibroblast cell lines). Also, we investigated whether development of tracheal stenosis could be predicted by any biological marker. MATERIALS AND METHODS: The tracheae of 30 rabbits were implanted with either nitinol stents, with or without paclitaxel elution, or a cobalt-based stent...

OBJECTIVE: The solution of severe tracheobronchial obstructions in early childhood means a great challenge. Biodegradable stents were intended to be a minimally invasive temporary solution which may decrease the number of interventions and limit the possible complications of stenting procedures. However, our first experiences have brought out a new, - especially in childhood - potentially life-threatening complication of this concept. METHODS: Five SX-ELLA biodegradable polydioxanone stents was applied in three patients because of severe tracheobronchial obstruction: congenital tracheomalacia (7 day-old), acquired tracheomalacia (10 month-old), and congenital trachea-bronchomalacia (10 month-old)...

Laurie Putz, Alain Mayné, Anne-Sophie Dincq
The indications for rigid bronchoscopy for interventional pulmonology have increased and include stent placements and transbronchial cryobiopsy procedures. The shared airway between anesthesiologist and pulmonologist and the open airway system, requiring specific ventilation techniques such as jet ventilation, need a good understanding of the procedure to reduce potentially harmful complications. Appropriate adjustment of the ventilator settings including pause pressure and peak inspiratory pressure reduces the risk of barotrauma...

INTRODUCTION: The close anatomical relationship between the oesophagus and bronchial tree results in formation of an oesophago-respiratory fistula in a subset of patients with advanced oesophageal or lung cancer. In those patients stenting of both the oesophagus and tracheobronchial tree is a valid option of palliative treatment. AIM: To determine the effectiveness, tolerance, quality of life, safety and survival after double stenting procedures. MATERIAL AND METHODS: Retrospective analysis of a prospectively collected database was performed, concerning consecutive patients with oesophago-respiratory fistulas treated with double stenting...

BACKGROUND: Currently available silicone and metallic stents for tracheal stenosis are associated with many problems. Granulation proliferation is one of the main complications. The present study aimed to evaluate the efficacy of paclitaxel drug-eluting tracheal stent in reducing granulation tissue formation in a canine model, as well as the pharmacokinetic features and safety profiles of the coated drug. METHODS: Eight beagles were randomly divided into a control group (bare-metal stent group, n = 4) and an experimental group (paclitaxel-eluting stent group, n = 4)...

Occurrence of bronchial artery aneurysm is rare, and it has been detected in less than 1 % of all selective bronchial arteriography cases. Here, we present a case of a bronchial artery aneurysm caused by a tracheal stent migration. A 59-year-old man was operated on for esophageal cancer, where an esophageal-tracheal fistula occurred 1 week after operation. Surgical repair of the esophageal-tracheal fistula was performed using a muscle flap, but this not results in fistula closure. Consequently, a self-expanding covered metallic tracheal stent was implanted for rescue, and this resulted in fistula closure...
