The genomic test uses cells obtained from standard cytology brushings taken from the
mainstem bronchus during a lung cancer diagnostic bronchoscopy.
In our ED, a chest X-ray or computed tomography scan is routinely performed after tube placement to detect
mainstem bronchus intubation.
The main components of an airway (i.e., trachea, carina, left
mainstem bronchus, and right
mainstem bronchus) were all made using onsite 3D printers using Platinum Series ABS Filaments (Airwolf 3D Printers, Costa Mesa, CA) which are composed of acrylonitrile-butadiene-styrene copolymer.
The prosthesis was found in the left
mainstem bronchus (Figure 1).
The right lower lobe bronchus (30%) and left
mainstem bronchus (20%) were the most common locations of foreign bodies [3].
His trachea was not deviated and his left
mainstem bronchus was 50 mm in length.
The proximal edge of the granulation tissue began approximately 2 cm inferior to the stoma, and it extended nearly to the
mainstem bronchus, a distance of approximately 1.0 cm.
An esophagram was subsequently performed, and demonstrated a fistulous connection between the esophagus and the left
mainstem bronchus (Figures 1 and 2).
Mainstem bronchus intubation with endo tracheal tube.
The lesion measured approximately 3.5 to 4 cm in length, at the right membranocartilaginous junction, above the carina and just proximal to the entrance of the right
mainstem bronchus. Right-sided bronchial injuries in the setting of chest trauma occur more frequently than on the left [4] and especially at this weak histological junction.
Then, with its bent blocker balloon tip angled towards the left, the deflated and lubricated Coopdech catheter was passed within the ETT lumen blindly and with little difficulty through the Murphy eye into the left
mainstem bronchus (Figure 2C).
Station 10.--Hilar nodes: Nodes immediately adjacent to the
mainstem bronchus and hilar vessels including the proximal portions of the pulmonary veins and main pulmonary artery
