CLASSIFICATION OF CARINAE
Our proposed nomenclature for the carinae in the bronchial tree is shown in Figure 1. The abbreviation, MC, describes the main carina dividing the two major bronchi. The carina dividing the bronchus to right upper lobe and right bronchus intermedius is termed RC 1 (right carina 1) and the carina between right middle lobar bronchus and bronchus to right lower lobe is termed RC 2 (right carina 2). Similarly, LC 1 (left carina 1) describes the carina between bronchus to anterior segment of the
COMMENTS
The new nomenclature is simple to use and avoids confusion in describing the appropriate carina. Furthermore, lengthy descriptive terms can be eliminated in recording bronchoscopic findings regarding the carinal involvement in various diseases. The uniform use of the new nomenclature by bronchoscopists, thoracic surgeons, pulmonologists, thoracic roentgenologists, and pulmonary pathologists will bring precision to the description of carinae.
The rationale behind the proposed nomenclature is

Silicone Y-stent Placement for a Secondary Right Carina
2017, Seminars in Thoracic and Cardiovascular SurgeryCitation Excerpt :The length and diameter of the stenosis were assessed using flexible and rigid bronchoscopes, an endobronchial ultrasonic probe with a balloon, and pre-procedural static images, as described previously.3 A 14-mm Dumon Y-stent (Novatech, La Ciotat, France) was selected from our large stock of stents, cut on-site to a 25-mm length for the bronchus intermedius and to 7 mm each for the middle lobe bronchus and basal bronchus, and placed at the carina between the right middle lobe bronchus and the lower lobe bronchus (secondary right carina, RC22) by pushing with rigid grasping forceps without fluoroscopic guidance (Fig. 2C-E). The procedure time was 129 minutes.
Imaging parenchymal lung diseases with confocal endomicroscopy
2012, Respiratory MedicineCitation Excerpt :An Olympus 1T260 bronchoscope was used to evaluate the central airways and then advanced into the most distally accessible bronchi, whereupon the probe was gently advanced beyond the distal opening of the working channel until recognisable images were obtained of the acinus. During normal respiration, successive pCLE video loops were acquired of up to six bronchopulmonary segments (BPSs) named according to international nomenclature.25 In each PLD patient, an attempt was made to optically biopsy contrasting BPSs, displaying both maximal and minimal radiological signs of disease.
