“…This approach uses highresolution multirow detector computed tomography (CT) scanning to obtain high-resolution 3-dimensional endoluminal images to the level of the segmental bronchi. 35 Contrast chest CT scans with 3-dimensional reconstruction is widely used to delineate major thoracic vessel and airway anatomy. However, this modality frequently underestimates the degree and length of airway narrowing, and hence should be used as an adjunctive investigative tool only.…”

Congenital tracheal stenosis (CTS) is a serious and rare condition. In most cases, stenotic lesions are composed of complete tracheal rings of cartilage. The severity of symptoms correlates with the length of affected trachea, the presence of concomitant respiratory conditions, degree of luminal narrowing, and any bronchial involvement. Critically, CTS is a disorder that can lead to life-threatening respiratory insufficiency in children. Thus, it is a clinical entity that demands timely diagnosis and treatment. This review will firstly discuss the anatomy and pathophysiology of CTS and outline the various clinical presentations associated with the disorder. In addition, methods of diagnosis and treatment strategies will be reviewed, with a focus on contemporary surgical techniques. Finally, postoperative care of patients with CTS will be reviewed, and a contemporary multidisciplinary management approach will be presented.

“…In simulated cases, there is no constriction on this airway since there needs to be an unknown-free path for the system to be invertible (see subsection 2.3). In practice, bronchoscopy can be used to determine if plugs exist in the most proximal airways [41], which can thus be removed from the unknown set. Plugs in proximal generations are all detected.…”

In asthma and COPD, some airways of the tracheo-bronchial tree can be constricted, from moderate narrowing up to closure. Those pathological patterns of obstructions affect the lung ventilation distribution. While some imaging techniques enable visualization and quantification of constrictions in proximal generations, no non-invasive technique exists to provide the airway morphology and obstruction distribution in distal areas. In this work, we propose a method that exploits lung ventilation measures to access positions of airways obstructions (restrictions and closures) in the tree. This identification approach combines a lung ventilation model, in which a 0 tree is strongly coupled to a 3 parenchyma description, along with a machine learning approach. Based on synthetic data generated with typical temporal and spatial resolutions as well as reconstruction errors, we obtain very encouraging results of the obstruction distribution, with a detection rate higher than 85%.

“…In either case, there is a combination of necrosis and/or fibrosis, leading to a progressive stenosis that is typically in a subglottic position or in the upper third of the trachea. CT is highly accurate in detecting the extent of such lesions and is, therefore, very useful in treatment planning for stent placement and subsequent follow-up [46][47][48] .…”

Recent state-of-the-art computed tomography and improved three-dimensional (3-D) postprocessing techniques have revolutionized the capability of visualizing airway pathology, offering physicians an advanced view of pathology and allowing for appropriate management planning. This article is a comprehensive review of trachea and main bronchi imaging, with emphasis on the dynamic airway anatomy, and a discussion of a wide variety of diseases including, but not limited to, congenital large airway abnormalities, tracheobronchial stenoses, benign and malignant neoplasms and tracheobronchomalacia. The importance of multiplanar reconstruction, 3-D reconstruction and incorporation of dynamic imaging for non-invasive evaluation of the large airways is stressed.
