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
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 .
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).
