The use of tracheobronchial stents for compromised large airways is increasing. We provide a case series highlighting some of the complications of airway management in patients with tracheobronchial stents in situ and propose an approach for dealing with this potentially complicated situation.

Scott H. Randell, Ph.D. M any disease processes in airways are characterized by altered epithehial cell phenotype. The spectrum ranges from loss of cilia through mucous cell hypertrophy, hyperplasia, and squamous metaplasia to neoplasia. A useful step toward understanding the regulation of airway cell proliferation and differentiation is elucidation of progenitorprogeny relationships. The curre...

BACKGROUND: Thoracic injury overall is the third most common cause of trauma following injury to the head and extremities. Thoracic trauma has a high morbidity and mortality, accounting for approximately 25% of trauma-related deaths, second only to head trauma. More than 70% of cases of blunt thoracic trauma are due to motor vehicle collisions, with the remainder caused by falls or blows from b...

Thoracic trauma is a significant cause of morbidity and mortality in both adults and children. It is a leading cause of death in approximately 25% of multiple trauma patients and, when associated with other injuries, it causes death in additional 50% of multiple trauma patients, usually as a result of hypoxia and hypovolemia. When cardiac trauma is not involved, mortality from isolated penetrat...

Human lungs are constantly exposed to a large number of Aspergillus spores which are present in ambient air. These spores are usually harmless to immunocompetent subjects but can produce a symptomatic disease in patients with impaired antifungal defense. In a small percentage of patients, the trachea and bronchi may be the main or even the sole site of Aspergillus infection. The clinical entiti...

Plastic bronchitis, a condition associated with widespread mucous plugging of the tracheobronchial tree, is an increasingly recognised bronchoscopic finding in acute chest syndrome of sickle cell disease. Removal of casts by bronchoscopy is technically challenging. We describe a child with acute chest syndrome where bronchoscopic removal of extensive tracheobronchial plastic casts was facilitat...

Pulmonary amyloidosis can be classified into tracheobronchial diffuse alveolar-septal and nodular parenchymal forms. Tracheobronchial amyloidosis can be further subdivided into diffuse and focal varieties. The latter is rare. We report a patient with a focal intrabronchial deposit of amyloid who presented with haemoptysis. The haemoptysis ceased following bronchoscopic removal of this deposit.

Unexpected and puzzling variations in bronchial anatomy might be discovered during bronchoscopy. The occurrence of congenital tracheobronchial anomaly is estimated to range between 1% and 12% of the overall population.1 We present 2 rare cases of congenital bronchial anomaly that were discovered during bronchoscopy and that emphasize the value of computed tomogram (CT) in diagnosing congenital ...
