Why it happens The most common causes are a lung infection during childhood, such as pneumonia or whooping cough that damages the
bronchi, and smoking.
We collected 1.0 cm-long fragments of the cranial and caudal portions of the trachea, tracheal bronchus, main
bronchi and lungs, washed in distilled water for 20 min and post-fixed in 1 % osmium tetroxide solution (Polyscience[R], Inc.
It can be explained by lower activity of an inflammatory process in the
bronchi in children from the Groups I and II associated with reduced transudation of protein through the vascular wall.
Amyloidosis may affect various tissues and organs, commonly kidneys, heart, liver, nervous system, and skin, while very rarely it affects trachea and
bronchi.
Groundnuts were the most commonly aspirated foreign bodies with a majority being localized in the
bronchi. In majority of the patients, the foreign bodies were retrieved successfully by rigid bronchoscopy.
Particles of 2-6 [micro]m in diameter, thought to be deposited in the
bronchi by analysis using the cascade impactor, are targeted to relatively proximal
bronchi (Figure 4).
However, whether the truncation of terminal
bronchi will influence the airflow in the model is unknown.
It was observed that the primary right and left
bronchi arise from the bifurcation of the trachea, immediately dorsal to the base of the heart.
Rarely are they encountered within the
bronchi, and rarely still do they get large enough to cause symptoms.
In addition, distance at which apical
bronchi was given off was also recorded.
This condition results in airway dilatation in the trachea and
bronchi. Tracheal diverticula may also occur, mainly in the posterior trachea [8].
When foreign bodies are stuck in the
bronchi for a long time, various complications such as atelectasis, chronic lung infection, abscess, and bronchiectasis may develop (2).
