This case describes successful reconstruction of a long-segment tracheal defect using AlloDerm as the conduit for reconstruction. A 38-year-old woman who had undergone a thyroid lobectomy in 2011 presented several months later unable to swallow. Chest computed tomography results revealed a tracheal/esophageal mass and a subsequent bronchoscopy, and esophagogastroduodenoscopy results revealed an upper esophageal/tracheal mass with two areas concerning for fistula. She underwent a bronchoscopy with a tracheal stent and percutaneous endoscopic gastrostomy placement...

The study's objective was to determine effects of relative size and placement location of endoluminal stents on incidence of complications and survival for canine tracheal collapse. Measurements were obtained on lateral radiographs before and after stenting to determine percent of the trachea occupied by the stent. These values were monitored over time and compared to complication rates and survival. Overall median survival time was 502 days. Six month survival rate was 78%, 1 yr survival was 60%, and 2 yr survival was 26%...

We describe the implantation of an absorbable, custom-made stent of polydioxanone to treat tracheomalacia in a 5-month-old patient with extrinsic compression by a double aortic arch. The use of an absorbable, oversized stent treated the tracheal collapse caused by vascular compression, avoided removal procedures, and allowed the infant's growth. The use of an oversized stent prevented stent migration and gave minimal problems of granulation.

Although tracheobronchial stents are widely used for tracheal obstruction due to malignant or benign stenosis, stent migration has been reported as a major postoperative complication. A self-expandable metallic stent (SEMS) is more easily introduced compared with silicone stents. However, it is also difficult to remove or replace without complications. We report a new technique for successful SEMS adjustment using a flexible bronchoscope with two biopsy forceps.

We have developed the algorithm for the choice of the surgical strategy for the treatment of chronic post-traumatic laryngeal stenosis with the purpose of enhancing the effectiveness of the management of the patients presenting with this condition. The proposed approach envisages obtaining anthropometric characteristics of the patients, determination of the type of his (her) neck and constitution, construction of the regressive models of the clinically significant laryngometric parameters based on the results of the clinical observations including the dimensions of the glottal fissure and the position of the vocal folds, calculations of the size of the autotransplant and the length of the T-shaped tube based on the results of the mathematical analysis of the anthropo- and organometric characteristics of the concrete patient, the laryngoplastic and prosthetic treatment of the newly formed laryngo-tracheal passage...

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...
