The term tracheobronchomalacia refers to excessively compliant and collapsible central airways leading to symptoms. Although seen as a coexisting condition with various other pulmonary condition, it may cause symptoms by itself. The condition is often misdiagnosed as asthma, bronchitis or just chronic cough due to a lack of specific pathognomonic history and clinical findings. The investigation revolves around different modes of imaging, lung function testing and usually confirmed by flexible bronchoscopy. The treatment widely varies based on the cause, with most cases treated conservatively with non-invasive ventilation...

Autologous airway epithelial cells have been used in clinical tissue-engineered airway transplantation procedures with a view to assisting mucosal regeneration and restoring mucociliary escalator function. However, limited time is available for epithelial cell expansion due to the urgent nature of these interventions and slow epithelial regeneration has been observed in patients. Human airway epithelial cells can be expanded from small biopsies or brushings taken during bronchoscopy procedures but the optimal mode of tissue acquisition from patients has not been investigated...

A 56-year-old male who had received transcatheter coil deposition 10 years ago for an arteriovenous malformation (AVM) was admitted to our hospital because of persistent hemosputum. Chest radiograph and bronchoscopy revealed straightened coil bundles in his air way. Recently, less invasive transcatheter intervention has been performed more frequently for treatment of AVM than surgical resection. In our case, however, chest radiography and bronchoscopy showed that the coils might migrate from the deposited site to the airway...

Pulmonary artery sling (PAS) is a rare congenital condition in which the left pulmonary artery (LPA) arises from the right pulmonary artery, and then passes between the trachea and the esophagus to reach the left lung, thereby forming a sling around the airway. It is often associated with intrinsic tracheal stenosis due to complete cartilaginous rings. Therapeutic management nowadays consists of one-stage reimplantation of the LPA and tracheoplasty with cardiopulmonary bypass support. Here, we present a 7-week-old boy with PAS and long-segment tracheal stenosis (LSTS) who underwent surgical intervention consisting of reimplantation of the LPA and slide tracheoplasty...

PURPOSE: Electromagnetic tracking is the gold standard for instrument tracking and navigation in the clinical setting without line of sight. Whilst clinical platforms exist for interventional bronchoscopy and neurosurgical navigation, the limited flexibility and high costs of electromagnetic tracking (EMT) systems for research investigations mitigate against a better understanding of the technology's characterisation and limitations. The Anser project provides an open-source implementation for EMT with particular application to image-guided interventions...

Foreign bodies in the airway, as well as those in the upper gastrointestinal tract, are life-threatening conditions and require prompt intervention. We report on a 44-year-old male patient who presented with 4 days of intermittent cough. A computed tomography was performed showing two metallic foreign bodies located in the right main bronchus and the duodenum. The knife blade was successfully removed by upper gastrointestinal endoscopy. However, the broken end of the blade was incarcerated in the right main bronchus and was removed via thoracotomy after the failure of endoscopic treatment...
