REVIEW
Laura Frye, Michael Machuzak
Airway complications remain a significant source of morbidity and mortality after lung transplantation. The incidence of complications is wide-ranging depending on the definition of the event, and there is still no universally accepted grading system for airway findings after transplantation. Additionally, although surgical technique and organ preservation have improved, other modifiable risk factors remain unclear. The management is as wide-ranging as the definitions. A multimodality approach is often needed with airway stenting reserved for refractory cases and stent management by a transplant team with expertise in placement and management of long-term complications...

BACKGROUND: Excessive dynamic airway collapse, which is often caused by the collapse of the posterior membrane wall during exhalation, is often misdiagnosed with other diseases; stents can provide support for the collapsing airways. The standard pulmonary function tests do not necessarily show change in functional breathing condition for evaluation of these type of diseases. METHODS: Flow characteristics through a patient's airways with excessive dynamic airway collapse have been numerically investigated...

BACKGROUND: Tracheal and bronchial stenosis is a life-threatening condition causing difficulty in breathing and even severe respiratory distress. The silicone tracheobronchial stents were placed using the rigid bronchoscopy into the trachea of severe dyspneic patients and they exhibited symptomatic improvement as well as a rise in the saturation of oxygen. The bronchial stents were applicable to many extensive malignant airway stenosis patients, such as those with esophageal cancer, lung cancer, and laryngeal cancer...

Airway management and ventilation during a tracheobronchial stenting procedure are challenging given that mandatory positive pressure ventilation cannot be fully achieved while using a rigid bronchoscope due to leakage from the scope tip. Biphasic cuirass ventilation is a negative pressure ventilation method using an external cuirass fitted to the anterior chest, which could assist in spontaneous breathing and ventilation support. We report 3 successful anesthesia cases in which we could maintain adequate ventilation and oxygenation, supported by biphasic cuirass ventilation, in patients undergoing tracheobronchial stent placement or removal procedures using rigid bronchoscopy...

Ultrasound is becoming a valuable diagnostic tool in the armamentarium of thoracic surgeons. We report its use to follow stent placement in the laryngotracheal position for management of life-threatening neoplastic obstruction. For this purpose, a 15-MHz linear probe was placed in the midline at the level of the cricoid cartilage. Ultrasound performed daily at bedside showed normal movement of vocal folds and no stent dislocation. This strategy may be an alternative to computed tomography scan or endoscopy to follow stent placement in extrathoracic airways...

A trachea is a tubular structure composed of smooth muscle that is reinforced with cartilage rings. Some diseases can cause sagging in smooth muscle and cartilaginous tissue. The end result is reduction (narrowing) of the trachea diameter. A solution to this problem is the use of tracheal stents, which are small tubular devices made of silicone. One is inserted into the trachea to prevent or correct its constriction. The purpose of tracheal stent use is to maintain cartilage support that would otherwise be lost in the airway...

Relapsing polychondritis (RP) is a rare systemic autoimmune disease that affects cartilaginous structures. RP causes tracheobronchomalacia (TBM) by affecting the bronchial cartilage. TBM is a fatal condition characterized by excessive weakening of the walls of the trachea and bronchi. We herein report a case of a 73-year-old man who experienced sudden respiratory failure due to TBM caused by RP. Immunosuppressive treatment did not improve his respiratory failure. Multiple metallic stentings dramatically improved his severe airway symptoms...

BACKGROUND: Stereoscopic bronchoscopy is a new diagnostic tool to measure the diameter and cross-sectional area of the airway. The stereoscopic bronchoscope, which operates the same as a standard bronchoscope, utilizes 2 lenses to measure the airway using the principles of triangulation. Furthermore, the stereoscopic bronchoscope has the capability to measure the size of the airway during intervention in real-time, including variable stenosis. MATERIALS AND METHODS: To prospectively compare preoperative stereoscopic and multidetector computed tomography (MD-CT) images to select the appropriate stent size for airway stenosis...

Pulmonary artery sling (PAS) is a rare disease frequently associated with severe malacia and stenosis of the trachea. We present a two-day-old newborn that underwent urgent surgery for PAS and needed prolonged respiratory support afterward. Temporary airway stenting above the level of the tracheal bifurcation was performed five days after surgery to overcome severe airway obstruction caused by tracheomalacia and laceration of the tracheal mucosa after diagnostic bronchoscopy. Two days after the procedure, the child could be extubated and after two weeks the stent was removed without complications...

More than half of primary lung cancers are not resectable at diagnosis and 40% of deaths may be secondary to loco-regional disease. Many of these patients suffer from symptoms related to airways obstruction. Indications for therapeutic endoscopic treatment are palliation of dyspnea and other obstructive symptoms in advanced cancerous lesions and cure of early lung cancer. Bronchoscopic management is also indicated for all those patients suffering from benign or minimally invasive neoplasm who are not suitable for surgery due to their clinical conditions...

BACKGROUND: Venovenous extracorporeal membrane oxygenation (VV ECMO) is used to support gas transfer of patients suffering from respiratory failure during various procedures. The purpose of this study was to evaluate the technical feasibility and safety of fluoroscopic stent placement under respiratory support with VV ECMO in patients with critical airway obstructions. METHODS: We reviewed the records of 17 patients (14 male and 3 female; mean age: 63 years; range, 30-82 years) who underwent self-expandable metallic stent (SEMS) placement under VV ECMO respiratory support for critical airway obstruction caused by malignant (n=16) or benign (n=1) etiology...

Noninvasive ventilation has been widely used in the management of acute respiratory failure in appropriate clinical settings. In addition to known benefit of alleviating the need for invasive mechanical ventilation, recent literature suggested its beneficial use in the process of endotracheal intubation. Search of the PubMed database and manual review of selected articles investigating the methods and outcomes of endotracheal intubation in difficult airway due to hypoxemic respiratory failure and the role of noninvasive ventilation in this process...

BACKGROUND: Airway stents are traditionally used in central airway obstructions to maintain airway patency. Historically, distal bronchial stenting within lobar and segmental bronchi has not been amenable to stenting. In addition, there are questionable benefits to stenting small airways. The Atrium iCast stent is a polytetrafluoroethylene covered stainless steel balloon deployed stent which can be deployed through a flexible bronchoscope under direct visualization. The purpose of this study was to assess the feasibility, complications, and long-term impact of using this stent in patients with lobar bronchial stenosis either secondary to malignancy or benign etiologies...

The use of venovenous extracorporeal membrane oxygenation (VV-ECMO) has traditionally been limited to a narrow set of clinical circumstances, such as acute hypoxic respiratory failure, submassive pulmonary embolism, and cardiopulmonary collapse. Within the pediatric population, there have been cases of VV-ECMO in the context of extrinsic airway compression by a mediastinal mass, typically in the setting of either a lymphoma or germ cell tumors. However, the use of VV-ECMO for adults with extrinsic airway compression is comparatively limited...
