OBJECTIVES/HYPOTHESIS: Intubation is an essential component of intensive care, yet it does have potential complications. Posterior glottic stenosis (PGS) is among the most severe sequela. Risk factors are poorly understood. One hypothesis is that large endotracheal tubes (ETTs) in smaller airways may increase risk. Because tracheal diameter is proportional to height, we designed a case-control study to evaluate the association between intensive care unit (ICU)-patient height (proxy for tracheal diameter) and their risk of postintubation PGS...

We report a simple endovascular repair for symptomatic aberrant right subclavian artery (ARSA) in an 11-year-old girl. She had undergone tracheostomy due to hypoxic encephalopathy after cardiac surgery and suffered from dyspnea. Computed tomography revealed tracheal stenosis caused by a vascular ring made with an ARSA and the right common carotid artery. Transcatheter ARSA embolization using an Amplatzer vascular plug and coils was performed. Symptoms improved within a few days after this intervention and no complications such as upper extremity ischemia were encountered...

Venovenous extracorporeal membrane oxygenation (VV-ECMO) is used not only support gas transfer of patients suffering from respiratory failure, but also to manage hypoxic patients with critical airway obstruction during various procedures. We present a case in which we electively used VV-ECMO to facilitate tube placement and tracheal biopsy in a 67-year-old female with critical tracheal stenosis. The patient was transferred to our hospital for a surgical treatment after emergent tracheostomy for postoperative management of cerebral hemorrhage in right putamen...

Surgery for laryngeal cancer and the following recurrent tumor growth may further change the anatomy of the airway. Airway management during anesthesia induction is challenging for the patients undergoing secondary surgery due to recurrence of laryngeal cancer or its postoperative complication, but it has never been reported. In this report, we described three cases of anesthetic induction which had different process of airway events. The first case was given intravenous general anesthetic for induction and experienced failed intubation, difficult mask ventilation and emergent tracheostomy, eventually were rescued successfully...

Tracheal injury, stenosis, and malignancy demand tracheal reconstruction, which often fails due to the lack of a functioning epithelium. We performed an extensive comparative analysis to determine optimal biomaterials for developing tracheal epithelial grafts with mucociliary function. We screened Hyaluronan-Poly(Ethylene Glycol), Chitosan-Collagen, Collagen Vitrigel Membrane, Fibrin Glue, Silk Fibroin, and Gelatin based on various parameters including mechanical strength, bulk degradation, cell attachment, spreading, metabolic activity, focal adhesion formation, and differentiation into ciliated and goblet cells...

Background: The primary objective of the study was to evaluate the health-related quality of life (HRQL) of patients with benign post-intubation tracheal stenosis considered as unfit for surgical treatment. Secondary objectives were: (I) to determine if clinical variables (gender, age, total treatment time, and type of tracheal device) could influence HRQL and (II) to compare the results with a normal standardized population. Methods: Prospective study between August-2014 and December-2016 including patients with tracheal stenosis treated with silicone stents, T-Tubes or tracheostomy...

We reported the role of endobronchial ultrasound as complement to standard diagnostic exams to better define the benign tracheal stenosis (i.e., thickness and tracheal cartilage integrity) and to plan the treatment with flexible instead of rigid bronchoscope. Under sedation and spontaneous ventilation, the flexible bronchoscope was inserted through the laryngeal mask airway that assured the ventilation. The stenosis was first resected with cold scissors and then dilated with balloon catheter. This strategy was successfully applied in five consecutive patients...

BACKGROUND: Hydrogen-oxygen mixture (H2-O2) may reduce airway resistance in patients with acute severe tracheal stenosis, yet data supporting the clinical use of H2-O2 are insufficient. OBJECTIVES: To evaluate the efficacy and safety of breathing H2-O2 in acute severe tracheal stenosis. METHODS: Thirty-five consecutive patients with severe acute tracheal stenosis were recruited in this prospective self-control study. Air, H2-O2 and O2 inhalation was given in 4 consecutive breathing steps: air for 15 min, H2-O2 (6 L per min, H2:O2 = 2: 1) for 15 min, oxygen (3 L per min) for 15 min, and H2-O2 for 120 min...

BACKGROUND: Endoscopic management of tracheal stenosis may be challenging, especially in the case of complex stenosis placed near the vocal folds, and needing stent placement. Herein, we evaluated the utility of the three-dimensional (3D) airway model for procedural planning in a consecutive series of patients with complex airway stenosis and scheduled for endoscopic treatment. METHODS: This strategy was applied to 7 consecutive patients with tracheal stenosis unfit for surgery...

Idiopathic laryngotracheal stenosis is a fibroinflammatory stenosis in persons without alternative explanation such as trauma, intubation, or autoimmune disease. Patients are usually females of child-bearing age. We report on an 11-year-old male who developed progressive dyspnea and stridor. Bronchoscopy revealed 90% stenosis of the cervical trachea. He underwent serial balloon dilation with steroid injection; stenosis decreased to 20%. He had no history of intubation or trauma. Histologic and laboratory workup for autoimmune disease was negative...

Postintubation tracheal stenosis is preventable yet commonly occurring clinical condition. Early in the disease, nonspecific symptoms may predominate but once the stenosis reaches a critical stage life-threatening respiratory compromise may ensue. Bronchoscopic interventions are an invaluable tool in the management both as a primary treatment and as an interim procedure before the surgery. Optical dilatational tracheoscopy is a safe and minimally invasive procedure in the treatment of benign tracheal stenosis...
