08% of the population and is defined as a supernumerary bronchus arising from the inner wall of the right main bronchus or bronchus intermedius
opposite to the origin of the right upper lobe bronchus.
There was severe stenosis of the right bronchus intermedius
and proximal left main stem bronchus and a hypoplastic right lung (Fig.
Lower border--The upper border of the lower lobe bronchus on the left; the lower border of the bronchus intermedius
on the right
Bronchus intermedius is the most vulnerable part of the airway, and collapse of the right middle and lower lobes may occur.
The largest group of lymph nodes as identified by CT scan is located in the subcarinal area (87%), and the most common sites of airway compression are the left main bronchus (21%), right main bronchus (14%) and bronchus intermedius (8%).
We describe a rare bronchial anomaly in a 2-month-old girl in which the right upper lobe, middle lobe, and lower lobe bronchi all originated at the same point as a result of a developmental teratogenic long right main bronchus and an absent bronchus intermedius.
Bronchography demonstrated a long right main bronchus and the apparent absence of a bronchus intermedius (figure 3).
The maximum stenosis in the trachea, right main bronchus, bronchus intermedius and left main bronchus was measured, if present.
There were a total of 62 stenoses, comprising 14 in the trachea, 6 in the right main bronchus, 22 in the bronchus intermedius, and 20 in the left main bronchus.
858) compared with the figures for the trachea, bronchus intermedius and left main bronchus.
909) between the sets of measurements in the bronchus intermedius, with a high consistency value (ICC consistency 0.
A metallic Wallstent (Schneider, Minneapolis, MN) was used at this second intervention in the same sites, with additional stenting in the right main stem bronchus, bronchus intermedius
and right lower lobe bronchus.
