PURPOSE To evaluate the diagnostic value of multidetector CT (MDCT) and its multiplanar reformation (MPR), volume rendering (VR) and virtual bronchoscopy (VB) postprocessing techniques for primary trachea and main bronchus tumors. METHODS Detection results of 31 primary trachea and main bronchus tumors with MDCT and its MPR, VR and VB postprocessing techniques, were analyzed retrospectively w...

Congenital fistulae between the tracheobronchial tree and oesophagus usually originate from the lower end of the trachea or right main bronchus. The case history is presented of a man in whom a fistula between the oesophagus and left main bronchus was not diagnosed until the age of 48.

A 44 year old man with poorly controlled diabetes mellitus developed endobronchial mucormycosis, which totally obstructed the right lower lobe bronchus. The lesion was removed through a rigid bronchoscope. Two weeks later the bronchus was free of mucormycosis histologically and on culture.

A 75-year-old female underwent a High Resolution Computed Tomography (HRCT) scan for recurrent bronchitis and cough. HRCT images showed an anomalous supernumerary bronchus to the right upper lobe directly arising from the right side of distal trachea, corresponding to Tracheal Bronchus (TrB). TrB can cause recurrent right upper lobe pneumonia and special care is requiring during endotracheal in...

In addition to its emerging immunodulatory properties, theophylline is a bronchodilator and also decreases mean pulmonary arterial pressure in vivo. The mechanism of action of this drug remains controversial; adenosine antagonism, phosphodiesterase (PDE) inhibition and other actions have been advanced to explain its effectiveness in asthma. Cyclic adenosine monophosphate (AMP) and cyclic guanos...

The amino acid and sugar composition of mucins from various organs is similar but not identical. This could arise by one or more of the following: organ-specific processing of a single core protein, organ-specific splicing of a single mucin mRNA, or organ-specific expression of various mucin genes. To begin to investigate the source of this variability, we examined (a) immunological cross-react...

The endotracheal tube with a movable bronchial blocker, Univent tube, used to effect one-lung ventilation is easy to use in endotracheal intubation. However, problems are often encountered when inserting the blocker into the bronchus. We herein describe a method which enables the easy blind insertion of the blocker into the left or right bronchus. The techniques of inserting the blocker into th...

Background. Typical pulmonary carcinoids represent less than 5% of primary lung tumors. In patients with typical bronchial carcinoid, formal surgical resection still remains the gold-standard treatment. Data regarding long-term outcome in using flexible bronchoscope-based modalities under conscious sedation is very limited. Objectives. We sought to investigate, over extended follow-up period, t...

Necrotizing tracheobronchitis and acute airway obstruction from invasive mycosis developed in a patient who had undergone bone marrow transplantation. The infectious process obstructed the airway and disintegrated the walls of the right mainstem bronchus and pulmonary artery. The airway was cleared using rigid bronchoscopy to extract the detritus. The patient died of hemorrhage after rupture of...

An incidental string-like structure spanning the lumen of the intermediate bronchus was found during bronchoscopy in an 18-year-old woman. We consider that the lesion may be a rare fibrous anomaly of the bronchus and may be closely related to a bronchial web. We have named this unusual structure 'bronchial string'.
