For exact orientation inside the tracheobronchial tree, clinicians are in urgent need of a navigation system for bronchoscopy. Such an image guided system has the ability to show the current position of a bronchoscope (instrument to inspect the inside of the lung) within the tracheobronchial tree. Thus orientation inside the complex tree structure is improved. Our approach of navigated bronchos...

Endobronchial lipoma is a rare neoplasm of the tracheobronchial tree and it may cause irreversible pulmonary damage due to recurrent pneumonia. Rarely, it may mimic bronchial asthma. We present a 53-year-old woman with an endobronchial lipoma, which had been treated as a bronchial asthma for four years. She also had developed recurrent pneumonia three times.

Chest trauma can affect any one or all components of the chest wall and thoracic cavity (bony skeleton, lungs and tracheobronchial tree, heart and great vessels, esophagus and diaphragm). This review is focused on the pathophysiology, diagnostic and treatment of blunt and penetrating thoracic injuries.

Tracheostomy is a life saving procedure and many patients are discharged with permanent tracheostomy tubes. We report the rare occurrence of a fractured tracheostomy tube migrating into the tracheobronchial tree and highlight the clinical manifestations of this uncommon complication that carries the potential risk of fatal respiratory obstruction.

A small ventilation failure alarm which can be used with all types of lung ventilator is described. The entire patient circuit can be removed and autoclaved easily. Activation of the unit is by a removable key, a mains failure warning is provided, and alarm may be muted during aspiration of secretions from the tracheobronchial tree.

Granular cell tumors (GCTs) are generally benign neoplastic tumors of neural origin that have little malignant potential. These tumors may occur in any location, including the tracheobronchial tree. Although an endobronchial location is believed to represent a small percentage of cases, GCTs should be included in the differential considerations of any endobronchial lesions leading to airway col...

Received August 8, 2002 Abstract Pulmonary sequestration is a congenital anomaly of lung parenchyma without a normal connection to the tracheobronchial tree and an anomalous systemic arterial supply. We report an 11-month-old boy with extralobar pulmonary sequestration. Magnetic resonance angiogram identified the arterial supply from aorta and venous drainage to azygous vein. Various imaging te...
